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

Deltakit is Riverlane’s open-source software development kit (SDK) for QEC which is designed to help researchers build, test and run QEC workflows as the field of quantum computing rapidly evolves.

You’ll sit right at the heart of Deltakit, working closely with users, partners and cross-functional teams to deeply understand real-world challenges and translate them into a compelling product direction. You’ll use a blend of user insight, product data and market context to cut through complexity and focus on what matters most.

You’ll own and evolve Deltakit’s strategy and roadmap, bringing together engineering, research, business development and marketing around a shared vision. You’ll strike the balance between bold, long-term ambition and what’s realistically achievable today, helping us build for the future of quantum computing while delivering value right now.

Beyond the roadmap, you’ll play a key role in bringing Deltakit to life for the community. From supporting launches to engaging directly with users, you’ll shape how we show up, tell our story, and communicate the product’s value in a way that excites and inspires people to build with it.
