Make your impact within a rapidly growing Fintech Company

Join BILL's Risk Engineering organization as a Senior Staff Software Engineer and take on some of the most consequential technical challenges in fintech. Our Risk Engineering team builds the platforms that protect hundreds of thousands of SMBs from financial harm, owning the risk decisioning infrastructure, onboarding compliance systems, access control frameworks, and real-time signal processing pipelines that operate across payment, lending, and spend products. The team sits at the intersection of security engineering and financial risk, where the decisions you build into software directly affect whether a small business can trust BILL with their money.

In this role, you will drive the technical vision and delivery of risk platform services with a security-by-default, platform-first mindset, from real-time decisioning engines and onboarding compliance workflows to privileged access controls and cloud security infrastructure in AWS. You will partner closely with Product, Data Scientists, Compliance, Risk Strategy and Infrastructure teams to turn complex fraud, regulatory, and identity signals into reliable, low-latency systems. A key part of this role is elevating engineering excellence by embedding AI-assisted workflows into design, testing, and development cycles to accelerate team velocity and code quality. This is hands-on technical leadership: you will not only define strategy but deliver production systems that raise the platform and security bar across the enterprise.
