AI/​LLM Engineer - Remote Opportunity at Mercura

About the Role

We are looking for an AI/LLM Engineer to join our dynamic team at Mercura. As an AI/LLM Engineer, you will play a pivotal role in building agentic AI systems end-to-end. This is a fast-paced, hands-on role for engineers with high agency, strong technical depth, and a founder mindset. You’ll work on building reliable AI systems in production - from retrieval and LLM orchestration to tool-using agents and product integration. If you’re a passionate builder who excels at the intersection of LLMs, data systems, AI, data engineering, and full-stack development, this is your opportunity to shape how users interact with AI in real-world workflows. Join us in our mission to bring AI to the backbone of our economy.

What You'll Do

• Design and build LLM-powered agentic systems end-to-end, from experimentation to production deployment.
• Build retrieval and context pipelines (RAG, hybrid search, structured retrieval) to enable reliable reasoning over large volumes of technical and commercial data.
• Develop evaluation and monitoring systems to measure and improve AI performance in production.
• Build scalable pipelines to process and structure large volumes of unstructured documents and data.
• Implement automated feedback pipelines that allow AI systems to learn from usage data and human feedback.
• Own the architecture and reliability of AI systems in production, ensuring they are fast, scalable, and robust.
• Collaborate with other stellar engineers to deeply integrate AI capabilities into the product experience.

Requirements

• Proven track record of architecting and building complex, AI/LLM-powered systems or agents in production.
• Experience with model serving, orchestration of agent workflows, monitoring, and scaling AI workloads.
• Strong experience in designing systems that process and structure large volumes of unstructured data.
• Proficiency in Python is required.
• Experience in full-stack development (React / Typescript / FastAPI) is a plus.

Nice to Have

• Experience with machine learning frameworks and tools.
• Familiarity with cloud platforms and deployment strategies.
• Understanding of AI ethics and responsible AI practices.

What We Offer

• Guaranteed career advancement opportunities in a rapidly growing team.
• An ambitious team that feels like family and sees their work as more than just a job.
• Real shares in our company with the most favorable tax treatment - no VSOP/ESOP.
• Free team dinner (up to 4x/week) and UrbanSportsClub membership.
• Access to any AI or productivity tools you need.
• Easy relocation to Munich with comprehensive support packages.
