All open roles

Join Aqarios to Redefine the Future of Computing!

At Aqarios, we want to change how the world solves hard problems. We use quantum computing to tackle some of the most complex challenges companies face across industries. Join us and you'll work on technology that's still being figured out, in a setup that's flexible and gives you room to own what you do. Ideally you'd be with us in our Munich office, though remote within Germany works too.

Who We Are

Aqarios was founded to close the gap between quantum computing and problems companies actually need solved. Our aim is to make quantum genuinely useful for the hard, complex challenges that come up across many industry domains. We work with large enterprises to do that, sometimes through Luna, our platform, and sometimes through solutions we build for a specific customer. We're a team of around 15 people, spun out of LMU Munich. That means there's real academic depth behind what we do, paired with the day-to-day of shipping software that customers rely on.

Your Tasks

• Implementing gate-based circuits for optimization, mainly around QAOA and its variants

• Getting into circuit compilation, from transpilation and qubit routing to error mitigation

• Turning ideas from papers into working code and testing whether they hold up

• Shipping your work into Luna, our optimization platform, where customers actually use it

• Working closely with the team on our quantum stack and picking up how the pieces fit together

Your Qualifications

• A solid foundation in quantum computing, from lectures, a thesis or your own projects

• You've built circuits yourself, in Qiskit or a comparable framework, beyond copying tutorial notebooks

• Decent Python and a willingness to write clean code

• Exposure to QAOA, transpilation, error correction, or a thesis in that direction

• Enrolled as a student (Werkstudent requirement) in Physics, CS, Maths, or something adjacent. Late Bachelor's or Master's is the sweet spot

• You ask questions when you're unsure and take feedback well. Admitting you don't know something is genuinely fine here

• Based in or near Munich, or elsewhere in Germany if you work remotely

Your Benefits

At Aqarios, you’ll have the chance to grow alongside a company at the forefront of quantum innovation, building a career in a rapidly expanding field.

• Your work runs in production for customers

• A close look at deeptech, right where quantum algorithms meet real software

• Real influence on where our quantum stack goes

• Flexible work arrangements that adapt to your studies and exam phases

• A small team that supports each other, an office in central Munich and regular team events

• A Wellhub membership for gyms and fitness

🚀 Don’t just work - make an impact. Join Aqarios and help us shape the future of computing, one breakthrough at a time!
