Quantum Algorithm Engineer

Munich (preferred) · Remote possible within Germany · Full-time · Mid Senior Build quantum circuits for real optimization problems, own circuit compilation from transpilation to error mitigation, and ship what works into our flagship platform, Luna. 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 in active research, 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 just over 10, spun out of LMU Munich's QAR-Lab. 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 Design and implement gate-based circuits for optimization, mainly QAOA and its variants, including constraint-preserving mixersBuild out our circuit compilation, from transpilation and qubit routing to error mitigationDrive these topics on your own, from following the literature to deciding what we build nextShip your work into Luna, our optimization platform, and see it used by customersPublish what you find 𝗬𝗼𝘂𝗿 𝗤𝘂𝗮𝗹𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀 Hands-on experience building gate-based circuits beyond textbook examples, from industry or researchDepth in at least one of circuit compilation, error mitigation or quantum optimization algorithms, and interest in picking up the othersNice to have: Familiarity with quantum error correction and where the field is headingYou work independently. Given an open problem, you find your way to a solid answer without someone checking in every dayComfortable in Qiskit, PennyLane or comparable SDKs, and you write code others can read and maintainStrong Python and solid engineering habits. You structure code into modules, write tests, and are at home with Git, code reviews and CI. C++ or Rust on top is a plusA PhD in physics, CS or maths is a plus, as are publications and hands-on time with real QPUsYou ask questions when you're unsure and take feedback well. Admitting you don't know something is genuinely fine herePreferably 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. Flexible hours and a relaxed approach to where you work. Remote is fine, we'd just like to see you in the office about once a week if you're in MunichPublishing and going to conferences is welcome and supportedReal influence on where our quantum stack goesYour work runs in production and will be evaluated with customersA small team that supports each other, an office in central Munich and regular team eventsA Wellhub membership for gyms and fitness, and a Claude subscription for your daily work 🚀 Don’t just work - make an impact. Join Aqarios and help us shape the future of computing, one breakthrough at a time!
