AI/LLM Engineer

About the Role

This is a hands-on AI engineering role at a fast-growing, Y Combinator-backed B2B SaaS startup building AI-powered sales automation for distributors and manufacturers. You will work across the full stack to design and ship end-to-end AI systems that directly drive product growth and customer impact.

What You'll Do

• Build, deploy, and optimize AI agents end-to-end across the full stack.
• Work with embeddings and fine-tune LLMs for classification and reranking tasks.
• Optimize algorithms for product search and discovery.
• Apply RLHF and DPO techniques to align LLMs with human feedback.
• Build data pipelines to process large-scale unstructured data efficiently.
• Improve backend scalability, stability, and performance.

What We're Looking For

• 2+ years of engineering experience, with substantive AI/LLM or backend-oriented depth (not frontend-focused).
• Strong experience with NLP, LLMs, embeddings, ML, and AI-powered applications.
• Demonstrated experience building and scaling data and ML pipelines, including large-scale unstructured data.
• Hands-on experience applying RLHF or DPO to align LLMs with human feedback.
• Full-stack development skills using React, TypeScript, and Next.js.
• Experience with containerization (Docker, Kubernetes), cloud infrastructure (AWS, Azure, or GCP), and infrastructure as code (Terraform).
• Strong computer science fundamentals.
• Ability and willingness to work on-site in Munich on a regular basis.
