Senior Compiler Engineer at Riverlane Ltd

Cambridge, UK | Full-time | Permanent | Hybrid

Salary: £65,000 - £80,000 GBP DOE. We will also consider part-time applications for this role. Please indicate your preferred working schedule in your cover letter. We are able to consider a range of levels of experience, and are therefore advertising this role at different levels of seniority. Please apply to the role you feel best suits your skills and experience.

About us

Riverlane’s mission is to make quantum computing useful, sooner. From advances in material science to complex chemistry simulation for drug design and discovery, quantum computers will help solve some of the world’s most important challenges. Riverlane is building the quantum error correction stack, Deltaflow, to make this happen. It’s a complex problem that requires a range of skills, talent, and passion.

We recently raised $75M in Series C funding to accelerate our cutting-edge R&D in quantum error correction (QEC), and are partnering 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 Tooling team is building out the compilation toolchain for fault-tolerant quantum computing. The compiler enables the quantum computer user to use representations of novel error correcting codes and to execute their programs with new real-time decoders. This role is a fantastic opportunity to help us do this.

You don't need a background in quantum computing to be successful in this role – quantum engineering requires a wide range of skills and disciplines, including classical computing skills. By applying your existing knowledge of computer science fundamentals, you will help Riverlane to build the critical compilation and runtime systems needed for this unique computing system. You will learn quantum computing along the way!

Riverlane’s mission 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, so the ability to adapt is important.

What you will do

1. Design and build system tools such as compilers, schedulers, and debuggers.
2. Develop functional and performance models of control systems and Deltaflow hardware (our quantum error correction stack).
3. Write correct, maintainable, and fast code.
4. Enable users to write and run fault-tolerant programs.
5. Build the software stack for error-corrected quantum computing systems.
6. Work with scientists and engineers to implement new error correcting codes and runtimes for new decoders.

Requirements

What we need:

1. Experience of shipping real software to real users.
2. Curiosity to learn new things.
3. Experience of working collaboratively, with a diverse range of people.
4. Broad knowledge of the whole software and hardware stack: compilers, operating systems, computer architectures.
5. Deep experience with LLVM, GCC, or other compiler toolchains.
6. Expertise in Python; expertise in C++ or Rust.
7. Interest in working in the quantum open-source ecosystem.
8. Excellent communication skills, both written and verbal.

Benefits

What you can expect from us:

1. A comprehensive benefits package, including annual bonus scheme, private medical insurance, life insurance, a contributory pension scheme (and much more).
2. Equity so that our team can share in the long-term success of Riverlane.
3. 28 days annual leave (plus bank holidays) and enhanced family leave.
4. A diverse work environment that brings together experts in many fields (including software and hardware development, quantum information theory, physics, maths, and many more) and over 20 different nationalities.
5. A learning environment that encourages individual, team, and company growth and learning, including an annual training and conference budget.
