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.

We will also consider part-time applications for this role. Please indicate your preferred working schedule in your cover letter.

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, these 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.

Systems Engineering bridges the gap between Riverlane and its customers. They act as the primary technical interface for our customers’ engineers to guide them through product integration and help with troubleshooting complex quantum systems. They are key to securing design wins and driving product development.

As an FPGA Engineer, you will configure our Deltaflow Hardware to connect Quantum Computers to provide low‑latency, high‑throughput systems that perform complex operations in a predictable and guaranteed way. You will use your knowledge and expertise to adapt the hardware to an ever‑changing quantum control system to support scientists that are running quantum experiments.

This is a fantastic opportunity to join Riverlane’s team, that is developing the world’s most advanced quantum error correcting algorithms. The Riverlane team is a mix of mathematicians, physicists and engineers, working together on a range of exciting and cutting‑edge projects.
