Job Technologies
Your role in the team
- You code because you love it - not because you have to.
- Whether you've been in the profession for 1 year or 6 years: what matters is that you understand what you write and enjoy improving it.
- You want to work on security-critical backend infrastructure - signature workflows, PKI, cryptography, REST APIs that run daily in enterprise environments.
- You want to build on-premise AI systems – no cloud APIs, no shared models.
- We integrate LLMs and RAG stacks on dedicated customer instances.
- Anyone interested in both worlds: also good.
- Who only cares about one thing: totally fine.

Our expectations of you
Education
- A completed degree in Computer Science, Mathematics, or a related field is a plus — but not a must, as long as you can demonstrate relevant knowledge.
Qualifications
- You have solid fundamentals in Java or in the AI environment.
- Curious, eager to learn, not afraid of complexity.
- You don't need to be a PKI expert or ML engineer – you just need to be eager to become one.
- You have knowledge of server architectures, LLM integration, or RAG stacks, and can independently take responsibility for features and systems after a brief onboarding.
- In both cases: solid fundamentals in Java (Track A) or Python / ML tooling (Track B), interest in the respective field, fluent German.
