AI/LLM Engineer

ABOUT THE ROLE

We are a Y Combinator-backed B2B SaaS startup building AI-powered sales automation for distributors and manufacturers. As an AI/LLM Engineer, you will design and ship end-to-end AI systems that directly power core product features, working across a small, high-velocity team that spans AI, data engineering, and full-stack development.

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.
• Design and optimize algorithms for product search.
• Apply RLHF and DPO techniques to align LLMs with human feedback.
• Build scalable data pipelines to process large volumes of unstructured data.
• Improve the scalability, stability, and efficiency of the backend.

WHAT WE'RE LOOKING FOR

• 2+ years of engineering experience, with a strong focus on AI and LLM-oriented work rather than frontend or non-NLP specializations.
• Strong hands-on experience with NLP, LLMs, embeddings, ML, and AI-powered applications.
• Demonstrated experience building and scaling data and ML pipelines for large-scale unstructured data.
• Experience applying RLHF or DPO to align language models with human feedback.
• Full-stack development experience using React, TypeScript, and Next.js.
• Familiarity with containerization (Docker, Kubernetes), cloud infrastructure (AWS, Azure, or GCP), and infrastructure as code (Terraform).
• Strong computer science fundamentals.

COMPENSATION & BENEFITS

• Salary: 80,000 to 130,000 EUR annually, depending on experience.
• Visa sponsorship: Available.
