Staff Software Engineer, Financial Infrastructure

Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation.

About the role

Make Replit the single place where businesses can buy everything they need through their agents. As a Staff Software Engineer on Replit’s Money team, you’ll set technical direction and build the commerce platform that lets users discover, evaluate, purchase, and manage the products and services they need to build and run their businesses—without leaving Replit.

Replit already enables businesses to accept payments through integrations such as Stripe. This role builds on that foundation to expand what businesses can buy and accomplish through Replit Agent. You’ll design commerce experiences that combine the simplicity consumers expect with the controls enterprises need, making agent-assisted purchasing useful, trustworthy, and reliable.

You’ll own architecture and lead cross-team delivery across merchant and service-provider integrations, agent tools, purchasing workflows, and the lifecycle after a transaction. The challenge goes beyond executing a payment: agents need to understand what a user wants, present clear choices and costs, act within delegated authority, and verify that the purchase delivered the intended outcome. You’ll stay hands-on with design and code while aligning partners, mentoring engineers, and turning an ambitious product vision into incremental customer value.

You will

• Set technical direction for Replit’s financial infrastructure, with an immediate focus on enterprise billing, spend controls, and financial correctness.
• Build shared services for usage-based billing, pricing, credits, subscriptions, and entitlements so product teams can launch without rebuilding billing.
• Automate enterprise contract lifecycles—from onboarding through amendments and renewals—keeping commercial terms, provisioned credits, and invoices in sync.
• Build timely budget enforcement, alerts, and overrides that give customers control over spend without disrupting their hosted apps.
• Make AI usage understandable: attribute costs to the right 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 catch discrepancies before customers do.
• 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.
• Stay hands-on while leading cross-team delivery, mentoring engineers, and partnering with Product, Finance, Sales, and Support.

Required skills and experience

• A track record of Staff-level technical ownership: 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.

Preferred Qualifications

• 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.

Bonus Points

• 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.
• Experience with cloud marketplace billing, payment recovery, or fraud and dispute workflows.
• Familiarity with agentic commerce or delegated spending. These are additional strengths, not requirements.

What we value:

• Customer outcomes: success means a business can get what it needs through its agent, with clear costs and a verified result—not merely a completed API call.
• User control and trust: agents act within explicit authority, surface consequential choices, and make purchases and ongoing commitments understandable.
• Consumer simplicity and enterprise readiness: straightforward experiences should coexist with the controls organizations need.
• End-to-end ownership: we own the experience from intent through purchase, fulfillment, and ongoing management.
• Pragmatic technical leadership: we build on what exists, deliver incremental value, and invest in correctness and extensibility where they matter.
• Clear collaboration: we document decisions, surface risks early, and help other teams and partners succeed.
