Fullstack engineer (AI platform & APIs)

We’re Hiring: Fullstack Engineer (AI Platform & APIs)

Stockholm | Help Build Europe’s Sovereign AI Stack

Berget AI is building a developer-first, sovereign AI platform on open infrastructure. We run our own GPU hardware and provide Kubernetes-native inference APIs and platform services. We’re expanding the core product team and are looking for a fullstack engineer who enjoys owning systems end-to-end and making complex infrastructure feel simple and reliable.

What you’ll work on

You will design, build, and operate backend services powering Berget AI’s platform, including inference APIs, OpenAI-compatible endpoints, internal product APIs, and usage and billing flows.

You’ll own features from idea to production: architecture, implementation, testing, deployment, monitoring, and iteration. You’ll keep releases flowing, fix bugs quickly, and continuously improve reliability and performance.

You’ll build Kubernetes-native services with strong focus on observability, security, and operational robustness. You’ll actively participate in incident response and ongoing security work, treating operational safety as a core product concern.

You’ll work closely with inference, platform, and community roles to translate real user needs into stable, developer-friendly APIs.

What you bring

You have strong experience building backend services in TypeScript/Node.js and designing clean, reliable APIs. We use Koa as our backend framework and run everything on Kubernetes with RKE2. We’re obsessed with automation and use FluxCD for GitOps deployments, so we can trust the system to heal itself when needed.

You’re comfortable working with React for frontend development and enjoy creating intuitive developer experiences. You’re familiar with modern frontend tooling and understand how to build responsive, accessible interfaces.

You’re comfortable owning systems from PR to production and understand distributed systems fundamentals, failure modes, and secure service design. You have experience with secrets management (Vault) and understand security best practices for cloud-native applications.

You care about quality, reliability, and making infrastructure approachable for developers. Experience with Kubernetes-native application patterns is a strong plus. Familiarity with inference runtimes (vLLM, SGLang) or AI/ML systems is a bonus, not a requirement.

You’re pragmatic, collaborative, and enjoy working in small teams with high ownership.

Why Berget

You’ll help shape the core APIs and developer experience of a European sovereign AI platform, with real ownership, fast feedback loops, and close collaboration across engineering, product, and community.
