Staff Software Engineer (Agentic Commerce & Payments)

Join Replit's Money team as a Staff Software Engineer, where you'll set the technical direction and build a commerce platform that allows users to discover, evaluate, purchase, and manage the products and services they need to build and run their businesses. You'll own the architecture, lead cross-team delivery, and design commerce experiences that combine simplicity with enterprise controls. This is a hands-on role that requires strong engineering and system design skills, as well as experience in building extensible third-party integrations and handling complex customer-facing products.

• 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.
• 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.

• Experience building extensible third-party integrations and handling asynchronous events, duplicate requests, partial failures, and changing provider capabilities
• 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 product judgment: you can turn complex, multi-step workflows into simple user experiences and balance rapid delivery with correctness and long-term flexibility
• Strong hands-on engineering and system design skills, including API design, data modeling, distributed workflows, and thoughtful evolution of existing systems
• Experience mentoring engineers and improving the quality of architecture, implementation, and operations beyond your own projects
• A security-conscious approach to authentication, authorization, credentials, sensitive data, and actions performed on a user’s or organization’s behalf
• Comfort using AI-assisted development tools while taking responsibility for the correctness, security, and maintainability of the code you ship
• Demonstrated ability to align engineering and cross-functional partners on technical direction, document decisions clearly, and drive execution without relying on reporting authority
• Experience building commerce platforms, marketplaces, purchasing or procurement systems, or products that connect buyers with multiple vendors
• Experience with agent tool calling, multi-step agent workflows, or evaluations for reliable execution of actions against external systems
• Familiarity with payment and purchase lifecycles, including authorization, checkout, subscriptions, fulfillment or provisioning, refunds, and reconciliation
• Experience building enterprise capabilities such as approval workflows, role-based access, purchasing policies, budget controls, or audit trails
• Experience with Stripe or other payment providers, developer platforms, or partner integration ecosystems
• Experience with emerging agentic-commerce protocols, MCP, or delegated authorization for agent-initiated transactions
• Experience integrating software and service catalogs, pricing and availability, entitlements, or automated provisioning
• Familiarity with recurring and usage-based costs, renewal management, international purchasing, or multi-provider transaction workflows
• These are additional strengths, not a checklist; prior experience spanning every commerce domain or payment provider is not expected
