About the role

Staff Software Engineer on Replit’s Money team responsible for architecting and delivering the commerce platform that enables agent-based purchasing, integrations with merchants and providers, and end-to-end purchase lifecycle beyond checkout.

Responsibilities

  • Lead end-to-end purchasing experiences through Replit Agent: translate user intent into relevant options, communicate prices and terms, obtain appropriate authorization, execute purchases, and confirm fulfillment or provisioning.
  • Build extensible integrations with merchants, software vendors, and service providers so the platform can expand its commerce offering without rebuilding each workflow from scratch.
  • Build on existing Stripe and payments capabilities, extending payment integrations where needed to support new purchasing experiences rather than treating basic payment acceptance as a greenfield problem.
  • Design agent-facing APIs and tools with clear contracts, secure credentials, scoped permissions, spending limits, and appropriate confirmation for consequential actions.
  • Partner with product and security to support enterprise purchasing requirements such as role-based access, approval workflows, purchasing policies, and auditable transaction histories, while keeping simpler purchases easy.
  • Own the purchase lifecycle beyond checkout: provisioning and access, order and subscription state, receipts, renewals, cancellations, refunds, and reconciliation across providers.
  • Make agent-driven transactions reliable with idempotency, verified events, durable state, safe retries, and recovery from partial failures; evaluate whether workflows complete the authorized task without duplicate purchases or unintended spend.
  • Lead ambiguous initiatives across teams, define incremental milestones, stay hands-on with implementation, and raise the engineering bar through mentoring, design reviews, and production ownership.
  • Set the architecture and technical roadmap for agentic commerce, making Replit a single place to discover, buy, and manage the products and services businesses need.

Qualifications

  • A track record of Staff-level technical leadership on complex customer-facing products or platforms, taking ambiguous initiatives from architecture through launch and production operation across multiple teams.
  • Strong hands-on engineering and system design skills, including API design, data modeling, distributed workflows, and thoughtful evolution of existing systems.
  • Experience building extensible third-party integrations and handling asynchronous events, duplicate requests, partial failures, and changing provider capabilities.
  • Strong product judgment: you can turn complex, multi-step workflows into simple user experiences and balance rapid delivery with correctness and long-term flexibility.
  • A security-conscious approach to authentication, authorization, credentials, sensitive data, and actions performed on a user’s or organization’s behalf.
  • Demonstrated ability to align engineering and cross-functional partners on technical direction, document decisions clearly, and drive execution without relying on reporting authority.
  • Experience mentoring engineers and improving the quality of architecture, implementation, and operations beyond your own projects.
  • Comfort using AI-assisted development tools while taking responsibility for the correctness, security, and maintainability of the code you ship.
