Design Engineer

What we're looking for

• Evidence of discovery. You've changed your own mind about what to build because of something a user said or did. You can tell us about a time you were wrong.
• Evidence of analytics. You've made a product decision from data you instrumented yourself. You know the difference between a metric that moved and a metric that mattered.
• Taste. You notice when spacing is off, when a flow doesn't communicate, when an interaction feels sluggish — and you fix it without being asked. We'll look at what you've made.
• Real code shipped to real users. React and TypeScript to production. Not prototypes, not a bootcamp project. Some Python helps; we can teach it.
• AI as leverage, not as identity. We don't care which tools you use. We care that you've restructured how you work around them and can show us the difference it made.
• German and English. Our users are almost entirely German-speaking. You'll be in those conversations from week one.

How we work

In the office, Munich, five days a week. We build in the same room — decisions happen at desks, not in tickets. Relocation support if you're not here yet.

High pace, steep learning curve. Most of the team is here well past six. That's not a policy or a number we track, it's what building something this size with sixteen people currently takes, and it's a phase, not a permanent state. If you're optimising for predictable hours right now, this is the wrong role, and that's a completely reasonable thing to be optimising for.

This is not the role if you want specs handed to you, you separate "my design work" from "my engineering work," you need a design system before you can start, or your best work needs a slide to explain it.

About the Founders

We are Lukas, Stefan & Sean , the co-founders of Mercura.

We share a deep commitment to excellence and the discipline to pursue what others might consider impossible.

Two of us come from non-academic families, and we all know what it means to create our own paths and overcome barriers. This experience shapes our belief in equal opportunity and fuels our dedication to social mobility.

Lukas (left) is responsible for business development at Mercura. With his background as a Data Scientist at Allianz and at Google in Silicon Valley, he brings extensive expertise in data and AI.

Lukas’ family has been active in the construction industry for over 100 years, giving him a deep understanding and passion for the sector's specific needs.

Sean (middle) is responsible for technical development at Mercura. As a top 0.01% physicist, Sean earned a Silver medal for Germany at the International Physics Olympiad (IPhO), began researching with the Max Planck Institute at the age of 16, and has since published at leading machine learning conferences.

Stefan (right) leads product development at Mercura. Previously, he worked in management consulting at Bain & Company, where he helped manufacturers improve their operations.

Stefan leverages his research experience at the Massachusetts Institute of Technology (MIT) and Harvard Business School to develop innovative solutions for the industry.

At Mercura, we believe that the best ideas emerge when people from different backgrounds collaborate together. We hire based on ability, mindset, and values, and we live by one simple rule: the best idea wins.

Beyond Mercura, we actively support initiatives that promote diversity and gender equity and commit a portion of our personal income each year to organizations expanding opportunity for others.
