About Us
At THEKER, we're taking on one of the greatest challenges of the 21st century: redefining how physical work gets done in the world.
We are a robotics and AI company building intelligent, adaptable systems that solve problems traditional automation never could. We recently closed the largest robotics Series A in Europe's history, and we're looking for the top 0.01% of talent to take on that mission with us, and build the biggest company in the world.
By joining us, you will have the chance to do the most meaningful work of your life, setting a new standard for industrial automation and driving breakthroughs with integral reach, while being surrounded by a focused, talent-dense team that shares this ambition and is here to win.
Your role
We're looking for an AI Tooling Engineer to build the internal infrastructure that makes our engineering team move faster and smarter. This isn't a research role. It's about shipping tools that have a measurable impact on how we design, develop, and deploy robotic systems.
You'll work directly with engineers across software, hardware,



and operations to identify where AI can cut friction and then build it. That means LLM integrations, internal agents, evaluation pipelines, retrieval systems, and whatever else removes bottlenecks from the way we work. The team is small, the scope is wide, and the things you build will be used every day.
You'll have enough autonomy to make real technical decisions, and enough context on the product to make them wisely. A good quarter in this role means our engineers spend less time on repetitive cognitive work and more time on the problems only they can solve.
What we're looking for
- Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field.
- Solid Python skills and experience building production-quality software, not just scripts or notebooks.
- Hands-on experience with LLMs: prompt engineering, function calling, RAG, or fine-tuning.
- Ability to work autonomou
