Staff Engineer, Billing

Who we are About Stripe Stripe is a financial infrastructure platform for businesses. Millions of companies—from the world's largest enterprises to the most ambitious startups—use Stripe to accept payments, grow their revenue, and accelerate new business opportunities. Our mission is to increase the GDP of the internet, and we have a staggering amount of work ahead. That means you have an unprecedented opportunity to put the global economy within everyone's reach while doing the most important work of your career. About the team In this role, you'll be joining a small, focused team with a large mandate: enabling businesses and Stripes to extend Stripe Billing exactly to their needs. Our users accomplish the vast majority of their goals with what Stripe Billing provides out of the box, but when they need to tailor billing logic to their unique business model, this team provides the tools and capabilities to do it. We are in the early stages of building an extensibility platform for Stripe Billing and are working toward general availability. Our work unlocks enterprise customers with complex, bespoke billing requirements — directly contributing to Stripe's mission of increasing the GDP of the internet. Our team brings extensibility to Stripe's Billing products, enabling merchants to customize billing logic — from discount calculations to invoicing workflows — through user-authored scripts and orchestration of Billing primitives We collaborate closely with Billing domain teams and Stripe's Extensibility platform teams to identify and build high-leverage extension points across the billing engine We have shipped at Stripe Sessions two years in a row — most recently launching five new extension capabilities along with script upload and observability tooling; you can explore our public docs at docs.stripe.com/extensibility What you'll do As a Staff Engineer on the team, you'll own the technical direction of our extensibility platform and play a central role in how we grow from early adoption to general availability. You'll work closely with other Billing domain teams to identify where extensibility creates the most value, partnering with them to build those capabilities into their products as first-class features — not afterthoughts. This is a high-autonomy, high-ownership role on a team that is actively shaping a new product area at Stripe. You'll navigate novel engineering challenges — including how to safely execute user-authored logic inside Stripe's billing engine — and establish the technical patterns the rest of the team builds on. You'll also be a key voice in cross-functional conversations with Billing leadership and Extensibility platform teams as we scale adoption from early customers to a broadly available product. Responsibilities Define and drive the technical architecture of Billing’s extensibility platform, setting patterns and standards that scale across teams Identify high-leverage extension points across Stripe's billing system and partner with Billing domain teams to build them into their products as extensible, first-class features Own end-to-end technical solutioning for complex, novel problems — from initial design through production delivery — in an evolving product environment Build resilient systems that handle failures gracefully, including novel failure modes introduced by user-authored logic running inside Stripe's billing engine Drive adoption of Billing's extension capabilities by external customers and internal Billing teams, iterating based on real-world usage Collaborate with Billing leadership, product managers, and Extensibility platform teams to define and execute the team's technical roadmap Mentor engineers on the team and raise the technical bar through design reviews, code reviews, and hands-on collaboration Who you are We're looking for someone who meets the minimum requirements to be considered for the role.
