Mercura
AI Quote and Order Automation for Distributors & Manufacturers
AI Engineering Intern
About the role
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 AI 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 software engineering and AI, this is your opportunity to learn, experiment, and contribute.
What you will be working on
- Work across the full stack to build AI agents end-to-end
- Work with embeddings and fine-tune LLMs for classification and reranking
- Optimize algorithms for product search
- Apply RLHF & DPO to align LLMs with human feedback
- Build data pipelines to process large-scale unstructured data efficiently
- Make our backend scalable, stable and efficient
What we're looking for
- High agency and experience with building software and iterating quickly
- Experience with NLP, LLMs, Embeddings, ML, and AI-powered applications
- First Experience with full-stack development (TypeScript, Python, React, Next)
- 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
- You want to work in-person in Munich with more intensity than in a 9-5 job
Company Perks
- Free team dinner (up to 4x/week)
- UrbanSportsClub membership - join our team workouts 3x/week
- Easy relocation to Munich — our office is located in the Werk1 Startup Incubator, where you can rent a 1-bedroom apartment right next to the office for just €750/month
- Access to any AI or productivity tools you need
