Job Description:

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 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.

Job Responsibility:

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

Requirements:

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

Nice to have:

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)

What we offer:

Competitive Salary & Equity
401(k) Program with a 4% match
Health, Dental, Vision and Life Insurance
Short Term and Long Term Disability
Paid Parental, Medical, Caregiver Leave
Commuter Benefits
Monthly Wellness Stipend
Autonomous Work Environment
In Office Set-Up Reimbursement
Flexible Time Off (FTO) + Holidays
