Munich, Bayern, Deutschland Mercura Vollzeit 40.000 € - 80.000 € pro Jahr

Mercura is building AI software for the backbone of our economy.

We are one of the fastest growing companies from YC's W25 batch and raised a heavily oversubscribed round at one of the highest valuations in our cohort. After surpassing $1M in ARR in under a year, we are looking for team members ready to go all-in to help us reach our next milestone: $10M ARR by the end of 2026.

One of our co-founders, Lukas, grew up in a trades family that has been active in the construction industry for over 115 years. Having worked on the construction site himself, he learned first-hand how slow and manual quoting still is in the industry.

In an era where AI becomes ubiquitous, we set out on a deeply personal mission: bring AI to the backbone of our economy - to the companies that keep our world running.

We're looking for Full-Stack Engineering Interns to help us build AI systems end-to-end. This is a fast-paced, hands-on role for candidates with high agency. At Mercura, you will collaborate closely with the best engineers and gain real-world experience in building AI applications in an industrial B2B context.

If you're excited about full-stack engineering and AI, this is your opportunity to learn, experiment, and contribute.

  • Strong problem-solving capabilities and willingness to learn new technologies
  • You're excited to strive for excellence and build software in a fast-paced startup environment
