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 Software Engineer at Riverlane, you will help build the world’s first Quantum Error Correction (QEC) stack, a critical step towards making useful quantum computing a reality.
This role sits within Riverlane’s Explore research team, which focuses on advancing our decoding algorithms at the core of the QEC stack. These algorithms underpin both our product development and our research efforts and form a central part of how we push the field forward. The team brings together mathematicians, physicists and engineers, working closely across disciplines on challenging technical problems.
You will collaborate directly with researchers, contributing to research code, internal tools and production software. Your work will play an important role in translating new ideas into robust, high-quality software that colleagues and customers can rely on.
What you will do
As a Research Software Engineer at Riverlane, your work will vary and will include:
Developing research ideas and prototypes into correct, maintainable, and fast code.
Delivering reliable and optimised software implementations of cutting-edge decoding algorithm.
Maintaining and evolving repositories and software releases at the high engineering level.
Extending Riverlane’s software tools for quantum simulation and QEC decoding and analysis.
Sharing expertise and collaborating with other teams at Riverlane to guide the development of various parts of the QEC stack.
What we need
MSc in Mathematics, Physics, Computer Science, or a related technical field (or equivalent professional experience)
Proficiency in C++ and Python is essential
Experience with collaborative programming
Experience with software engineering tools: CI/CD, containers, version control, static and dynamic code analysis
Confidence in basics of linear algebra, discrete mathematics, and probabilities
Strong problem-solving skills
Ability to work effectively, both independently and as part of a team
A passion for learning and curious mindset
An interest in quantum computing
Strong written and oral communication skills, with the ability to discuss complex ideas
