Staff Software Engineer, Financial Infrastructure
About The Position
As a Staff Software Engineer on Replit’s Money team, you will set technical direction and build financial infrastructure and commerce capabilities that help businesses buy and manage products and services through Replit Agent. The role focuses initially on enterprise billing, spend controls, and financial correctness, while expanding on Replit’s existing payment integrations. You will design systems for agent-assisted purchasing that combine a simple customer experience with enterprise controls, making purchases understandable, authorized, reliable, and verifiable. You will own architecture and lead cross-team delivery for billing services, enterprise contract lifecycles, usage attribution, purchasing workflows, reconciliation, and post-transaction management. You will remain hands-on in design and implementation while collaborating with Product, Finance, Sales, and Support, mentoring engineers, and delivering incremental customer value. The position also includes production ownership, including testing, observability, incident response, and safe recovery from failures.
Requirements
- Track record of Staff-level technical ownership, including setting architecture and delivering complex initiatives across teams.
- Deep experience building and operating production backend or distributed systems.
- Strong fundamentals in API design, data modeling, databases, and event-driven architecture.
- Sound judgment around transactions, consistency, concurrency, idempotency, and failure recovery.
- Experience evolving live systems and migrating data without compromising correctness or availability.
- Product judgment that balances customer needs, delivery speed, and long-term system quality.
- Clear communication with technical and non-technical partners, including translating business requirements into system behavior.
- Hands-on leadership through implementation, design reviews, mentoring, and production ownership.
Nice To Haves
- Experience with billing, payments, subscriptions, credits, entitlements, or other financial systems.
- Experience with enterprise contracts, negotiated pricing, invoicing, or quote-to-cash automation.
- Experience with high-volume usage metering, pricing calculations, or low-latency spend controls.
- Experience building reconciliation, financial reporting, or auditable transaction histories with Finance and Accounting.
- Experience integrating billing, payment, or CRM platforms, with judgment about what to build versus buy.
- Experience with AI or cloud infrastructure billing, including variable costs and attribution across distributed workloads.
- Experience building customer-facing spend visibility, budgets, or internal tools that reduce manual billing work.

- Build timely budget enforcement, alerts, and overrides that give customers control over spending without disrupting hosted apps.
- Attribute AI usage costs to the correct customer, workspace, user, or agent, including delegated work without double-counting.
- Build reconciliation and audit trails that make balances and invoices explainable and help Finance identify discrepancies.
- Simplify the billing stack through safe migrations that preserve balances, transaction history, and customer access.
- Own production reliability through testing, observability, incident response, and safe recovery from duplicate events, delayed usage, and partial failures.
- Lead cross-team delivery while remaining hands-on, mentoring engineers, and partnering with Product, Finance, Sales, and Support.
