Product Engineer - Backend Developer

Your job will be to own and scale the backend that powers the E2B Dashboard https://github.com/e2b-dev/dashboard and SDK -the APIs, data, and services developers rely on to run, monitor, and debug their sandboxes. You're the backend counterpart to our dashboard engineers: they own the experience, you own the services and data behind it, and together you ship product end-to-end.

This is product/application backend - APIs, data layer, auth, billing, usage metrics, real-time log/metric pipelines. It is not our low-level infrastructure (Firecracker, orchestration, the sandbox runtime) - that lives with our Core and Platform teams, who you'll integrate with but not duplicate.

The split is roughly 80% Go backend, 20% TypeScript. You live in Go, but you're comfortable dropping into the Next.js app to wire things up end-to-end and unblock the frontend rather than throwing work over a wall.

You'll build enterprise-grade services that scale to 100k+ weekly active users. Responsibilities include:

- 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 like 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

This role requires a high amount of ownership and the ability to take projects from 0 to 1. You'll have deep autonomy to make backend and product decisions. If you see a better way to build something, you build it.

WHAT WE'RE LOOKING FOR

- 3-5+ years shipping production backend services, with deep expertise in Go

- Strong API design with REST/RPC, contracts, versioning, and an eye for the interface the frontend 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 and not be lost

- 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

If you join E2B, you'll get a lot of freedom. We expect you to be proactive and take ownership. You'll be taking projects from 0 to 1 with the support of the rest of the team.
