Cambridge, UK | Full-time | Permanent Salary: £72,000 - £90,000 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 are 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 platform for building, simulating and interpreting QEC experiments. As a Senior Software Engineer, you will own and lead the development of Deltakit , shaping its direction and ensuring it evolves to meet the needs of a growing and highly technical user community. This role sits at the intersection of research and engineering. You will take cutting-edge ideas from the forefront of QEC and turn them into robust, intuitive software that researchers can rely on. Day to day, this means driving the design and delivery of new features, improving performance and usability, and ensuring the platform scales as adoption grows. You’ll play a key role in planning and prioritising the development roadmap, aligning technical delivery with resear
