AI & Backend Engineer

Über diese Stelle

ABOUT THE ROLE

We're a seed-stage B2B SaaS company building an AI-powered support agent designed for technical, complex customer service workflows. Our product helps B2B teams auto-resolve difficult support tickets, equips human agents with AI-driven context and suggestions, and bridges the gap between support and engineering — all within a secure, compliance-first architecture.

We're looking for an AI & Backend Engineer to join our small, high-velocity team. You'll own end-to-end features across the full stack, shape AI-powered capabilities, and help scale the architectures that power our agents. This is a high-impact role at an early stage where your work will directly define the product.

Tech stack: Python, FastAPI, OpenAI models (GPT-4o, GPT-4.1, o3, o4-mini), Next.js, React, TypeScript, PostgreSQL, Firestore (GCP), Docker, Kubernetes.

WHAT YOU'LL DO

- Design and implement full-stack product features from concept to production.

- Develop and enhance AI features, including LLM pipelines, prompt engineering, and agent architectures.

- Collaborate with the team to plan, design, and ship new capabilities at pace.

- Help make internal workflows AI-native — actively experimenting with AI coding agents and tooling to improve team productivity.

WHAT WE'RE LOOKING FOR

Must-haves:

- 1–4 years of experience in backend or AI engineering (new graduates with strong AI project experience are welcome).

- Demonstrated ability to build and ship backend systems or AI pipelines to production.

- Hands-on experience integrating OpenAI models and crafting effective prompts.

- At least some experience working with AI agents (e.g. autonomous task agents, LLM-powered workflows).

- Experience designing end-to-end architectures and building AI-powered data or model pipelines.

- Proficiency with Next.js, React, and TypeScript for full-stack development.

- Experience with PostgreSQL and/or Firestore (GCP).

- Experience deploying and operating applications with Docker and Kubernetes.

- Hobby projects involving LLMs or related AI topics — we want to see genuine curiosity and self-driven exploration.

- Eligibility to work in Germany (visa sponsorship is available).

- Availability to work on-site in Munich, 5 days a week.

Nice to have:

- Heavy user of AI coding agents such as Codex, Claude Code, or Cursor — with concrete learnings or ideas about improving AI-assisted development setups.

- Background in B2B SaaS, customer support tooling, or developer tooling.

- Experience in a fast-paced startup environment (comparable to companies like Sierra, Intercom, Freshworks, Forethought, or similar).

LOCATION

This role is fully on-site in Munich, Germany, 5 days per week. Visa sponsorship is available for eligible candidates.
