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 Team Product Platform builds and owns the shared foundations the rest of Replit is built on, spanning the full stack so every other team can ship features safely and quickly. Identity & Authorization defines how people, agents, sandboxes, and services prove who they are and what they can do. These systems protect critical product and service interactions across Replit's web product, Agent, enterprise controls, and internal services. Our work is high-leverage and horizontal: when identity and policy are clear, reliable, and easy to adopt, every other team can move faster without rebuilding security controls. We are a small, collaborative team that values curiosity and clear thinking over pedigree, and we work in the open by bringing each other the problem rather than just the request. We care more about how you reason and build than the route you took to get here. About the Role As a Software Engineer , you will design, build, and operate the identity and authorization systems that protect critical interactions on Replit, including Agent acting on behalf of a user or holding their own identity. The work is guided by a few simple questions: Can every protected request prove which workload made it, which principal it represents, and who is acting on that principal's behalf? Can product teams express policy once and trust the same decision across web, mobile, Agent, and internal services? Can enterprise administrators control who can access each workspace, app, connector, and Agent capability without navigating a permission maze as well as having a legible ledger of decisions? Can Agent act for a user across long-running and durable work without receiving broad or long-lived credentials? Are identity and auth

With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. About the role This is a zero-to-one Product Engineering role on Replit's Money team. You'll bring our financial partnerships alive from scoping to integrating and operating them so that the builders on Replit, and the Apps and Agents they ship can transact reliably anywhere in the world. Money at Replit isn’t traditional payments. Builders are publishing apps that earn revenue. Agents are spending and being paid for work. New protocols for agentic commerce now exist to power the future of commerce: Shared Payment Tokens, the Agentic Commerce Protocol (ACP), the Universal Commerce Protocol (UCP), the Machine Payments Protocol (MPP). Replit is one of the platforms that will define what they look like in practice and lower the barrier to entry. To make any of that real, we need someone who can sit between Replit engineering and our financial partners including billing platforms, payment processors, agentic-commerce protocol partners, tax and compliance vendors to turn signed contracts into live, reliable integrations. You'll be the engineer partners ask for, and the engineer the rest of Replit relies on when a new monetization surface needs to ship. This role is a fit if you like writing code and you also like being in the room when a partnership is being scoped, because you know that the design decisions made in that room are the ones that bind the integration for years. You will Take financial partnerships from zero-to-one: scope the integration with the partner, pressure-test data and protocol specs, design the system, build it, ship it, and operate it.
