Job summary

E2B is seeking a backend engineer to own and scale the services behind the E2B Dashboard and SDK, focusing on APIs, data models, and real-time backends. You’ll work closely with dashboard engineers to ship features end-to-end and integrate with Core/Platform teams, primarily in Go with some TS work.

You’ll be building enterprise-grade services for 100k+ weekly active users, designing auth/billing/usage surfaces, and ensuring observability, security, and performance.

Qualifications

• 3-5+ years shipping production backend services, with deep expertise in Go.
• Strong API design — REST/RPC, contracts, versioning, and an eye for the interface the frontend actually needs.
• Solid with PostgreSQL: schema design, query optimization, migrations, and reasoning about data at scale.
• Backend fundamentals: authentication/authorization, server-side performance, and building real-time data flows (WebSockets, SSE).
• Working TypeScript (Next.js is a plus) competence — you won't live here, but you can move into the app-router frontend to wire up a feature end-to-end.
• Understand data fetching patterns on frontend side.
• Excited to work in person from Prague on a devtool product.
• Ownership mentality: you see projects through from conception to launch to iteration.
• Comfortable talking to customers and explaining technical tradeoffs.
• Not being afraid to take ownership of your part of the product.
• Great communication, curiosity, and interest in the AI space.

Responsibilities

• Owning the Go services behind the dashboard and SDK — APIs, data models, and the contracts the frontend builds on
• Designing auth/authorization, billing, and usage‑metering surfaces
• Building the real‑time backends (WebSockets, SSE) that feed sandbox logs and metrics to the dashboard
• Optimizing data access and server‑side performance — query design, caching, response times
• Partnering closely with dashboard engineers to ship features end‑to‑end, and with Core/Platform on the boundaries where product meets infrastructure
• Making architectural decisions around observability, testing, and security best practices
