Backend Developer

Stockholm, Sweden

We’re Hiring: AI Platform Developer (Backend & API)

Remote (Europe) | Part-Time or Contract | Help Build Europe’s Open AI Stack

We’re a new European inference and Kubernetes provider on a mission:

Champion open innovation. Power open models. Redefine model-as-a-service in Europe. We run our own hardware (incl GPU), only using open-source frameworks, and build infrastructure to make AI hosting fast, sovereign, and developer-friendly.

Now, we’re looking for a Backend/API Developer to help us scale our core systems.

What You’ll Work On

  • Design and build backend APIs powering our serverless inference platform for text, audio and image serving
  • Implement integrations with frameworks like vLLM, SGLang, and OpenAI-compatible APIs
  • Contribute to internal tooling and external-facing APIs for developers
  • Help shape a clean, robust, secure, and developer-centric architecture

What You Bring

  • Solid experience with TypeScript and Python
  • Familiarity with inference stacks like vLLM, SGLang, Ollama, Llama.cpp or similar
  • Comfortable building APIs and backend systems with production-ready quality
  • You use AI tools effectively—but stay fully in control of quality, reliability, and security
  • Bonus: experience working with Kubernetes-native systems (RKE2, Rancher, Harvester, OpenShift, K3s, microK8s), open models, or MLOps infra

Why This Might Be For You

  • You want to build AI infra that’s open, not locked down
  • You’re excited about joining an early-stage, technically ambitious team
  • You prefer autonomy, speed, and technical ownership over layers of process
  • You’d like part-time or contract work—with the option to go deeper over time
