The salary range for this role is broad, as we are able to consider varying levels of experience. Any offer made will carefully take into account level of experience (including relevant industry experience), transferable relevant skills and previous relevant achievements.
About us
the company'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, some breakthroughs can never be achieved. the company 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), the company 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
the company's QEC research only moves as fast as the software that supports it. Researchers working on decoding algorithms need tools they can trust: fast, correct, and built to last.
You'll sit within the Research teams, working alongside mathematicians, physicists and engineers to develop the simulation and analysis tooling that underpins their work. The quality of the software directly shapes what research is possible.
At Senior level, you'll take ownership of significant technical work and help researchers around you raise their engineering standards. At Staff level, you'll set direction across projects and may lead a small team.




This would suit someone who cares deeply about software quality and wants their work to directly shape what research is possible.
