Software Engineer - Open Source

Cambridge, UK | Full-time | Permanent | Hybrid Salary: £60,000 - £70,000 DOE We will also consider part-time applications for this role. Please indicate your preferred working schedule in your cover letter. About us Riverlane’s mission is to master quantum error correction (QEC) and unlock a new age of human progress. From advances in material and climate science, to complex chemistry simulation for new drug design, quantum computers will help humanity solve some of its most important challenges. But without QEC, the industry’s defining technical challenge, such breakthroughs can never be achieved. Riverlane is the world leader in QEC technology. QEC is a complex problem that requires a range of skills, talent and passion. Having raised more than $125M in funding to date to accelerate our cutting-edge R&D in quantum error correction (QEC), Riverlane partners with many of the world’s leading quantum hardware providers and government agencies to make fault-tolerant quantum computing a reality. We’re making remarkable progress and growing fast. About the role At Riverlane, our mission is to make it possible for anyone to write and run fault-tolerant programs on a quantum computer. A key part of that mission is Deltakit, our open-source, user-facing software platform for building, simulating and interpreting QEC experiments. As a Software Engineer, you will play a central role in shaping and evolving Deltakit , ensuring it continues to meet the needs of a rapidly growing and highly technical community. This is a role at the intersection of research and engineering. You’ll work closely with leading experts in QEC, translating cutting-edge ideas into robust, intuitive software that researchers can rely on. Your work will directly influence how users interact with Riverlane’s software ecosystem, helping to bridge the gap between theoretical advances and practical application. Beyond building features, you’ll engage actively with our user community, supporting adoption, und
