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

As a QEC Researcher (Simulation Development) at Riverlane, you will work on the development and productization of classical simulation techniques for fault-tolerant quantum computing and quantum error correction.

The team brings together mathematicians, physicists, and chemists, and works closely with leading researchers in quantum algorithms and QEC. A core part of the role is researching, developing, and documenting internal tooling to support the team for estimating quantities of interest in non-Clifford protocols.

This includes working with team members to design requirements for new capabilities for non-Clifford operations, investigating the accuracy, complexity, and limitations of simulation approximations, implementing high-performance computing solutions using best coding practices, and enabling large-scale studies non-Clifford QEC protocols and decoder performance.

Your work may include submitting novel simulator science to journals, working with internal and external partners on new software capabilities, working with open-source collaborators on multiple community simulation tools, and managing large numeric simulations.

You’ll collaborate closely with other QEC teams at Riverlane, including those working on logical operations, decoding and QEC code design across different qubit platforms.

What you will do 

• Develop and improve simulation tools for fault-tolerant quantum computing and quantum error correction.
• Research and recreate efficient simulation techniques for Clifford and non-Clifford quantum circuits.
• Maintain good coding standards and implement new features across multiple repositories for non-Clifford simulation.
• Engage in academic research activities, including reading and reviewing literature, participating in journal clubs, writing papers, and presenting work at conferences.
• Write code to test scientific ideas and contribute to software-focused research outputs and products.
• Lead or contribute to projects involving small, cross-disciplinary teams.
• Collaborate with other teams across Riverlane to integrate your work with related research areas.
• Build and maintain relationships with partners and collaborators in industry and academia.

What we need 

• A PhD with strong academic performance in a mathematically focused discipline, such as physics, theoretical chemistry, mathematics, or computer science.
• Experience working with and contributing to legacy code bases and on large coding projects, especially with professional development experience.
• Curiosity and motivation to learn new technical topics and apply your skills across quantum error correction and quantum algorithms.
• The ability to work both independently and collaboratively, sharing progress clearly with colleagues, contributing to technical discussions and problem solving.
• Strong written and verbal communication skills.

Even better if you have…

• Experience working on quantum simulations, especially stabilizer tableau simulations and related techniques. 

• Experience designing and running numerical simulations. 
• Experience conducting research in quantum error correction, either in academia or industry.

What can you expect from us

• A comprehensive benefits package that includes an annual bonus plan, private medical insurance, life insurance, and a contributory pension scheme 

• Equity, so that our team can share in the long-term success of Riverlane 

• 28 days annual leave, plus bank holidays and enhanced family leave 

• A diverse work environment that brings together experts in many fields (including software and hardware development, quantum information theory, physics and maths) and over 20 different nationalities 
• A learning environment that encourages individual, team and company growth and development, including a regular programme of learning events and training and conference budgets
