Staff Software Engineer, Agentic Commerce & Payments

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.

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.

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.

You will:

• 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.

Required skills and experience:

• 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.

Preferred Qualifications

• 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.

Bonus Points:

• 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.

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.
