Product Engineer
Build and scale the product backend (APIs, data, auth, billing, real-time metrics) powering E2B's Dashboard and SDK. 80% Go with some TypeScript/Next.js; requires 3-5+ years production backend experience, strong PostgreSQL skills, and end-to-end product ownership.
About the job
Responsibilities
- Own and scale the Go services behind the E2B Dashboard and SDK, including APIs, data models, and contracts for the frontend.
- Design and implement auth/authorization, billing, and usage-metering surfaces.
- Build real-time backends using WebSockets and SSE to feed sandbox logs and metrics to the dashboard.
- Optimize data access and server-side performance, including query design, caching, and response times.
- Partner closely with dashboard engineers to ship features end-to-end, and with Core/Platform teams on product-infrastructure boundaries.
- Make architectural decisions around observability, testing, and security best practices.
- Take projects from 0 to 1 with high ownership and autonomy for backend and product decisions.
Requirements
- 3-5+ years shipping production backend services with deep expertise in Go.
- Strong API design skills with REST/RPC, contracts, versioning, and focus on frontend interfaces.
- Solid experience with PostgreSQL, including schema design, query optimization, migrations, and reasoning about data at scale.
- Strong backend fundamentals: authentication/authorization, server-side performance, and building real-time data flows (WebSockets, SSE).
- Working competence in TypeScript (Next.js is a plus); ability to work in the Next.js app-router frontend to wire up features end-to-end.
- Understanding of data fetching patterns on the frontend side.
- Ownership mentality with ability to see projects through from conception to launch to iteration.
- Comfortable talking to customers and explaining technical tradeoffs.
- Great communication, curiosity, and interest in the AI space.
- Excited to work in person on a devtool product.
Nice-to-Haves
- Experience with Next.js.
- Proactive and ownership-driven approach in a fast-growing startup.
- Background or interest in AI agents and hyperscalers.
