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.

We recently raised $75 million to accelerate our cutting‑edge R&D. We partner with many of the world’s leading quantum computing companies and governments to accelerate their path to utility‑scale quantum computers. We’re making remarkable progress and growing fast. Join us!

We have an excellent opportunity for a proactive and technically proficient Systems Administrator to join our dedicated on‑site IT team. Reporting to our IT Manager, you’ll collaborate closely to maintain, enhance and scale our High‑Performance Computing (HPC) environment.
