Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide and over 500,000 business users, Replit is democratizing software development by removing traditional barriers to application creation.
About The Role As a Staff Product Engineer on Replit’s Product Platform team , you’ll build the shared product systems and primitives that power Replit’s core experiences — enabling product teams to ship faster and helping users (and agents) build better software.
The nature of software development has changed and Replit is at the forefront of that revolution. The product platform team builds and scales the primitives that Replit Agent uses to empower over 40 million users to build anything they want.
This role is ideal for a senior web engineer who’s shipped at scale, thrives in high-ownership environments, and can define what “good” looks like across reliability, performance, and developer experience.
We’ve hit a significant scale and have escape velocity. A number of our systems need to be scaled and rebuilt, so you’ll get to build these out for 0 → 1 → huge scale quickly.
You’ll work closely with product other engineers, platform engineers, designers, product managers, and go-to-market partners to deliver foundational capabilities that unlock entire categories of product development.
This is why we require product engineers with a strong product sense and past distributed systems experience that are excited about building at scale platform primitives!
What You’ll Do
Core areas you’ll work on Agents and Replit users depend on us to build applications (e.g. Connectors framework, Content/configuration primitives (CMS + product surfaces), Data/analytics/events + experimentation primitives).
Replit Agent as a principal in third party systems . Agent can be fully used within ChatGPT and publishes straight to the iOS app store. We’ll be doing loads of that.
Platform product teams rely on us to ship consistently (e.g. Identity & Access platform (SSO/SCIM), Localization/i18n platform, Notifications & communications platform).
Core web platform infrastructure (e.g. performance & page load optimization, observability and debugging workflows, caching strategy and reliability).
Required Skills And Experience
Bonus points
Experience working in environments with a high engineering bar (or a fast-growing startup where you shipped fast without burning out quality)
Experience with platform and distributed systems patterns (queues, workflows, caching, rate limiting, async processing)
Familiarity with systems like:
Redis, Postgres
Workflow engines (e.g. Temporal)
Auth and enterprise identity (SSO, SCIM)
Abuse protection and edge systems (Cloudflare)
Cloud platforms (GCP)
Observability (Datadog, Sentry)
Localization
Experimentation and event pipelines (Statsig, Segment, analytics/event tracking)
Excited about the future of programming, including agent workflows and developer tools
Exposure to agent ecosystems (e.g. MCP-style patterns, tool integrations, structured automation)
