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

Our Software team's mission is to enable anyone to be able to write and run a fault tolerant program on a quantum computer. The compiler is a critical part of this toolchain. This role is a fantastic opportunity to help us build and ship this toolchain for use by our hardware partners.The Senior role involves owning and leading parts of the software stack.

You could have a background in computer science,mathsorphysics. You might have experience in building classical compilers, orin designingfault tolerant logic representations.Youwillbring your background,experienceand passion for learning new things to buildRiverlane'ssoftware stack. The stack encodesRiverlane'snovel QEC codes and real-time decoder interfaces into a greenfield, modernLLVM MLIR-based compiler. You will helpRiverlanebuild the critical compilation and runtime systems needed forlarge-scale fault-tolerant quantum computers.

Riverlane'smission is exciting, but complex. It requires teams with a wide range of skills and perspectives, that communicate well and collaborate effectively to achieve truly innovative solutions. You will thrive in an environment where knowledge-sharing and continuous learning are the norm. We are moving fast in a brand-new market, where requirements change as the technology evolves, sothe ability to adaptis important.

What you will do

• Design and build system tools such as compilers, emulators, profilersand debuggers
• Design and implement correct, maintainable compiler optimizations, transformations, and analyses across multiple IR levels.
• Own a substantial part ofthe software stack for error-corrected quantum computing systems
• Mentor, guide and leadengineers in the team
• Lead collaboration with other engineering teams to integratetheir software and hardware artifacts with the compiler
• Work with scientists and engineers to implement new error correcting codes, and runtimesfornew decoders

What we need

• Curiosity to learn new things
• Experience of working collaboratively, with a diverse range of people
• Good communicationskills, both written and verbal
• Broad knowledge of the whole software and hardware stack: compilers, operating systems, computer architectures
• Experience in compilers (LLVM MLIR orothers),in particularexperiencein middle- and back-endareassuch asIRdesign, optimization passes,instructionselection, etc.
• Experience of shipping software to users
• Proficiencyin Python;proficiencyin C++ or Rust
• Interest in working in the quantum open-sourceecosystem

What can you expect from us

• A comprehensive benefits package that includesan annual bonus plan,private medical insurance, life insurance, and acontributory 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,physicsand maths) and over 20 different nationalities
• A learning environment that encourages individual, team and company growth anddevelopment, including a regular programme of learning events and training and conference budgets
