Who you are
This role is ideal for a senior platform-minded 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
7+ years of professional software engineering experience
Understanding of the full agentic software development stack, helping coding agents build, test and review correct code
Strong track record leading complex projects with cross-functional stakeholders
Experience building and operating platform systems that other teams depend on
Experience operating and scaling systems in production (reliability, performance, incidents, on-call readiness)
Strong product judgment: you can balance UX, speed, correctness, and long-term maintainability
Comfort working in modern web stacks such as TypeScript, React, Node.js, Postgres
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

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
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!
Lead major cross-team platform initiatives, taking foundational systems from 0 → 1 and scaling them to support millions of users
Build shared, extensible Agent primitives that Replit Agent can reuse safely and consistently (Meta Programming)
Identify the highest-leverage technical bottlenecks (performance, reliability, correctness, abuse, observability), then design and ship solutions for our scale
Raise the bar for engineering excellence through architecture reviews, code quality, reliability standards, and mentorship
Partner across teams to improve platform adoption, ergonomics, and velocity — turning platform work into measurable outcomes
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)
Example Projects You’ll Work On:
Connectors platform for agents — ship a secure connector framework (OAuth/permissions/data access) so agents can integrate with Slack/Notion/GitHub/etc
Agent-facing external surfaces — own high-quality embedded experiences (desktop/extension/embeds) that let agents act in-context across tools
Safety + abuse controls for agent actions — design permissioning, rate limits, and policy enforcement so agents can operate safely at scale
