By replacing outdated financial processes with innovative tools, we help businesses—from startups to established brands—make smarter decisions and gain control of their operations. And we don’t stop there: we’re creating the future of financial automation so businesses can spend more time on what matters. Working here means you become part of a vision-driven team that’s ready to tackle challenges and build cutting-edge solutions. We value purpose, drive, and curiosity—and we thrive in a fast-paced, ever-changing environment. We're remote-first, with office spaces in San Jose, CA and Draper, UT — and opportunities to connect in person when it counts. BILLders collaborate to deliver real impact for businesses that need more time in their busy weeks. BILL builds high performing teams and we seek to hire the best talent for every role. We're committed to building a workplace that fosters inclusion and diverse perspectives, valuing each person’s unique skills and experiences. We’d love to hear from you—you might be just what we’re looking for, whether in this role or another. ✨ Let’s give businesses more time for what matters. Customer Experience Operations at BILL handles 60K+ customer contacts per month across chat, phone, and email. We support SMB, mid-market, and enterprise customers with a mix of internal and BPO teams across four countries. We're standing up a new team inside CXO focused on building agentic AI systems that automate manual work, catch things before they fall through cracks, and give leaders visibility into their operations. The work isn't new. We've been building AI tools and delivering value ad hoc, but now it's our mandate. This is a founding team. You'd be shaping the architecture, the workflows, and the culture from the ground up. There's existing work to build on, but no inherited playbook to follow. You'll work directly with CARE leaders, QA, Advocacy, and WFM to identify what to automate and validate that it's working. In this role, you will: Automate repetitive operational workflows: CES reporting, QA transcript analysis, knowledge article maintenance, SOP-driven case workflows. Deploy standardized automations across Slack and Salesforce at scale. Flag stalled handoffs, aged cases, SLA breach risks, and duplicate cases before they become problems. Review DevRev/Cresta transcripts to ensure bots are behaving as expected. Give leaders self-serve access to data and insights. Deliver automated weekly/monthly business intelligence on cadence (site health, volume, SLA, CES). Detect escalation patterns and repeat contacts that nobody is connecting the dots on. Build memory architecture: bots that look at staffing, feedback, transcripts, and agent work together at scale. Know what happened last week and what's coming next. You will also: Connect and deploy orchestration layers (MCP, custom connectors) to automate CX business workflows and productize internal tools Measure operational reliability and system accuracy to ensure business metrics are being achieved: contacts deflected, cost avoided, hours saved. Design escalation patterns so the system knows when to surface to a human. Partner with the data team on structured data layers that keep AI outputs trustworthy. Productize what works so it scales across the org. We'd love to chat if you have: 5+ years building and deploying production systems. Python required. SQL strongly preferred. 2+ years working with LLMs in production: prompt configuration, tool use, function calling, RAG pipelines, agentic frameworks (MCP, custom orchestration, etc.) Experience building LLM orchestration and integration layers that connect AI agents to business systems. Multi-step workflows, tool coordination, memory management, error recovery. You understand context engineering: accuracy depends on what information reaches the model. You've structured context, routing logic, and retrieval pipelines for these systems at scale. You know how to measure operational reliability of AI systems: are they actually delivering the business outcomes they're supposed to? Comfort with ambiguity. You'll define the approach, not just implement specs. You can translate between technical implementation and business value: hours saved, contacts deflected, cost avoided. Familiarity with customer support operations: contact routing, SLAs, agent workflows, quality assurance. Bias toward shipping. Deploy, measure, iterate. Bonus points if you also have: Experience with Salesforce integrations or CX/support tooling (DevRev, Cresta, knowledge management systems) Data modeling or analytics background (dbt, Redshift, Trino) Experience building tools for non-technical end users Visa Sponsorship: Please note that this position is not eligible for visa sponsorship.

We're committed to building a workplace that fosters inclusion and diverse perspectives, valuing each person’s unique skills and experiences. We’d love to hear from you—you might be just what we’re looking for, whether in this role or another. ✨ Let’s give businesses more time for what matters. Make your impact within a rapidly growing Fintech Company Join BILL as Director of Developer Experience and Infrastructure Platform and lead the engineering organization that sets the foundation for how hundreds of services are built, deployed, and operated across the company. This team is the connective tissue of BILL's engineering culture: owning the developer tooling that engineers rely on from their first line of code through production, the platform automation that keeps pace with a growing codebase, and the service platform infrastructure that makes reliability possible at scale. BILL's platform is used every day by hundreds of thousands of small and midsize businesses managing cash flow, accounts payable, and financial operations. Your team will be responsible for keeping BILL's platform fast, reliable, secure, and exceptionally easy to build on. In this role, you will set the technical direction for developer tooling and service platform, drive the organizational change management needed to standardize how teams build and ship, and lead an AI-native developer experience strategy that fundamentally accelerates the software development lifecycle (SDLC) across the company. You will operate across the full engineering organization as both a technical authority and an influential leader. Responsibilities: Own the strategy and roadmap for BILL's AI-augmented developer platform across two core pillars: developer tooling (local development workflows, AI coding assistants, IDE context-injection, code automation, CI/CD, Code Review, and internal bots) and service platform (the infrastructure for building, maintaining, operating, and retiring services across the company's 250+ services). Drive company-wide change management to standardize how engineering teams build and ship, including defining service templating, common libraries, and AI-driven guardrails that proactively intercept security vulnerabilities and compliance drift during the generation phase. Lead, grow, and develop a team of engineers and engineering managers, partnering with the current team to restore stability and direction following org changes, and setting a high bar for craft, accountability, and AI tool fluency. Scale the developer experience: architecting the infrastructure required to embed coding assistants into daily workflows, optimizing knowledge base codebase context, and deploying agentic workflows to automate routine refactoring and migrations. Optimize the engineering "inner loop" by owning the strategy, tooling, and runtime configurations for local developer environments (workstations/laptops). Deliver fast feedback loops, containerized local environments, and robust containerized strategies that enable engineers to reliably build, debug, and test complex, multi-service architectures locally before code ever reaches a shared test environment. Operate as a senior technical leader and cross-functional partner, collaborating with engineering managers, architects, product, and the CTO to align platform investments with the company strategy. Define and track the metrics that matter: developer experience satisfaction, deployment frequency, system reliability, time-to-productivity for new engineers, and AI adoption metrics, using data to prioritize and communicate progress to senior leadership and build a data-driven culture. Represent the developer platform org in executive-level conversations, translating technical complexity into clear business impact and building trust with stakeholders across engineering and beyond. We’d love to chat if you have: 12+ years of experience in software engineering or infrastructure, with at least 5 years leading platform, DevX, or infrastructure teams at a Director level or equivalent scope. Proven track record of implementing, scaling, and measuring AI-assisted development tools (e.g., AI pair programmers, automated code review agents) across a scaled engineering organization (300+ engineers). Demonstrated ability to lead organizational change at scale: you have owned the rollout of engineering standards, tooling, or platform migrations that required buy-in across a distributed engineering organization. Extensive technical depth and architectural leadership in modern DevOps practices operating in the cloud: Specifically featuring production-scale experience with Kubernetes (k8s), ArgoCD, and GitLab CI/CD platforms (AWS environment preferred). You possess the credibility to deeply engage with principal engineers on pipeline optimization, build fleet management, and deployment strategies. Deep technical and strategic mastery of modern coding assistant technologies (e.g., GitHub Copilot, Cursor, Claude) and their underlying mechanics. You pair this technical depth with a sophisticated understanding of how to safely deploy these tools within a regulated fintech environment. Strong executive communication skills: you can present a system design retrospective, a platform strategy, or a staffing ask to a CTO or board-level audience with the same clarity you use with your team. Experience operating in a complex, multi-team engineering environment where influence matters as much as authority, and where aligning stakeholders with competing priorities is part of the job. Desired Qualifications: Experience building internal custom AI tooling, fine-tuning models for coding tasks, or building custom RAG pipelines to feed internal codebase context to developer agents. Background in fintech, payments, or other regulated, high-availability environments where reliability and security are first-class engineering concerns.

Make your impact at a leading Fintech Company Join BILL's AI Product Engineering team and help shape the future of intelligent financial automation. BILL processes millions of financial documents every month, and machine learning sits at the core of how we turn unstructured documents into accurate, actionable financial data. We are looking for a Staff ML Engineer to raise the technical bar across our AI/ML organization, someone who is equally comfortable getting hands-on with model training code and setting the multi-quarter technical direction for a team. This is a senior individual-contributor role with organization-wide influence. You will architect and build the next generation of our ML systems, spanning LLM-based extraction, fine-tuned open-weight models, intelligent routing, and the data foundations underneath them, while mentoring engineers and shaping how we evaluate, deploy, and iterate on models in production. Responsibilities : Own technical direction for high-impact ML initiatives end to end, from problem framing and research exploration through production deployment and measurement, across document understanding, field extraction, and model-serving infrastructure Stay hands-on: prototype, fine-tune, and ship models yourself; write production code alongside the engineers you mentor Lead our LLM strategy, including fine-tuning open-weight foundation models, designing evaluation harnesses, and making principled build-vs-buy decisions between self-hosted and frontier API models across accuracy, cost, latency, and privacy constraints Bring a research-oriented mindset to production problems: read and translate current literature into practice, design rigorous experiments and ablations, and know when a published technique will or won't transfer to our data distribution Design the data flywheel, including labeling pipelines, human-in-the-loop feedback, and drift monitoring, so our models improve continuously from production signals Set engineering standards for model evaluation, calibration, reproducibility, and responsible deployment; be the person others seek out for design reviews on anything ML-shaped Mentor and multiply: grow senior and mid-level ML engineers through code review, pairing, and technical guidance; influence roadmaps in partnership with product and platform leadership We’d love to chat if you have: Requires a minimum of 8 years of related experience with a Bachelor's degree; or 6 years and a Master's degree; or a PhD with 3 years of experience; or equivalent experience 8+ years in software/ML engineering with a demonstrated track record at Staff level or equivalent scope, leading technically while remaining deeply hands-on with the modern ML/AI stack (PyTorch, distributed training, experiment tracking, feature and vector stores) Direct experience fine-tuning LLMs, including supervised fine-tuning, LoRA/QLoRA, preference optimization (DPO/RLHF), and structured-output training, and taking fine-tuned models to production at scale Production experience in at least one of: recommendation systems, personalization, or search/ranking; you have built systems that learn from user behavior at scale, handled feedback loops and position bias, and shipped models where offline metrics had to survive contact with online reality Strong data reasoning fundamentals: sampling and class imbalance, evaluation design and metric selection, confidence calibration, leakage detection, distribution shift, and the statistical judgment to know when an A/B result or benchmark number is real versus noise Research-oriented mindset with shipping discipline: you follow the literature, form hypotheses, and run disciplined experiments, but you measure success by what reaches production and moves business metrics Nice-to-Have Experience with document AI / intelligent document processing (OCR pipelines, layout-aware models such as LayoutLM/Donut, vision-language models) Publications, patents, or open-source contributions in ML Experience with privacy-constrained ML (on-prem/VPC model hosting, PII handling, data governance in fintech or healthcare) Experience designing multi-model routing or cascade architectures balancing cost, latency, and accuracy Our ranges for each role and job level are based on a variety of factors including candidate experience, expertise, and geographic location and may vary from the amounts listed below.

We’d love to hear from you—you might be just what we’re looking for, whether in this role or another. ✨ Let’s give businesses more time for what matters. Make your impact at a leading Fintech Company We are the team of Software Development Engineers in Test (SDET) - the voice of quality within Engineering squads and the guardians of Continuous Delivery and Innovation. Quality is not a phase we own at the end of the pipeline; it is a discipline we build into every stage of development. As a Senior SDET, you will understand the technical design of applications, champion testability from the earliest design conversations, and hold a high bar for the quality of the components we ship. You will build test automation that delivers maximum, meaningful coverage in the most efficient way possible — catching defects early, preventing regressions, and giving the team the confidence to release continuously without compromising on quality. Responsibilities: Spend ~80% of your time on automation and enabling the team to drive quality through strong testing practices, taking an automation-first, AI-assisted approach to test design and authoring. Collaborate with Engineers, Product, and Design to solidify and validate feature requirements - clear acceptance criteria, specifications, and expected outcomes - early in the lifecycle. Partner with Engineering to create and evangelize quality practices, coaching developers to own more of their own test authorship over time. Write automated tests in TypeScript/Playwright across UI and API layers (functional, contract, and integration). Contribute to testing framework design and implementation, optimize the testing process, and enable quality gating within the CI/CD pipeline for the squad's deliverables. Leverage AI tools (test generation, self-healing locators, coverage-gap analysis, failure triage) to increase coverage and reduce maintenance overhead. Regularly write and complete manual and exploratory tests alongside automation to verify new features, cover edge cases, and catch regressions. Investigate and root-cause automated test failures, distinguishing product defects from flaky tests and infrastructure issues. Define and maintain release criteria, test plans, and coverage expectations across multiple squads. We’d love to chat if you have: Bachelors degree in Computer Science, Engineering, Mathematics, or equivalent work experience. 5+ years of professional experience on a software development team (cross-functional environment preferred). Experience designing, implementing, and running automated tests with Playwright (or a similar modern browser automation framework, with a willingness to work primarily in Playwright). Proficiency in JavaScript/TypeScript preferred; proficiency in any functional or general-purpose language considered. Hands-on experience with AI-assisted testing – using AI tools to generate tests, triage failures, maintain self-healing locators, or analyze coverage gaps – and a mindset of folding these into everyday workflows. API testing knowledge – REST/GraphQL, request/response validation, auth flows, and API-level automation. An innate ability to pick up and ramp on new technologies and languages quickly. Experience determining the cause of automated test failures. Experience documenting and completing manual tests. Experience writing release criteria and associated test plans. Knowledge of CI/CD pipelines and quality gates. Desired Qualifications: Payments industry experience or exposure to card issuing (virtual/physical cards, payment rails, settlement, reconciliation, or related domains). Experience with contract testing (Pact or similar) and visual regression testing (Chromatic, Percy, or similar). Experience introducing coverage gating and enforcing quality thresholds in the delivery pipeline. Familiarity with observability tooling (Datadog, Splunk) for test and production quality signals. Experience building or maintaining shared test frameworks/libraries used by other engineers. Exposure to evaluating non-deterministic / AI-powered features (eval frameworks, prompt/output validation) Our ranges for each role and job level are based on a variety of factors including candidate experience, expertise, and geographic location and may vary from the amounts listed below.
