About The Role
At Riverlane, our mission is to make it possible for anyone to write and run fault‑tolerant programs on a quantum computer. A key part of that mission is Deltakit, our open‑source, user‑facing platform for building, simulating and interpreting quantum error‑correction experiments. As a Senior Software Engineer you will own and lead the development of Deltakit, shaping its direction and ensuring it evolves to meet the needs of a growing, highly‑technical user community.
This role sits at the intersection of research and engineering. You will take cutting‑edge ideas from the forefront of QEC and turn them into robust, intuitive software that researchers can rely on. You’ll drive the design and delivery of new features, improve performance and usability, and ensure the platform scales as adoption grows. You’ll also play a key role in planning and prioritising the development roadmap, aligning technical delivery with research milestones, user needs, and broader organisational goals, defining technical direction, making architectural decisions and setting the standard for high‑quality code.
Responsibilities
- Lead significant parts of both the internal and external software stack for error‑corrected quantum computing systems
- Turn internal tools into external and public tools. Own the complete software cycle: design, development, testing, builds, workflows, releases
- Mentor, guide and lead engineers in the team
- Lead collaboration with other engineering teams to integrate their software and hardware artifacts with Deltakit
- Engage with the community of users and researchers to identify needs and formulate adequate responses
- Contribute actively to open‑source projects and lead the Deltakit open‑source community
- Organise and run workshops and tutorials for the community of users
Qualifications
- Strong technical foundation (e.g., computer science, mathematics, physics or similar)
- Experience designing and building high‑quality scientific or technical software, primarily in Python
- Ability to translate complex, research‑driven concepts into robust, scalable and user‑friendly solutions
- Broad understanding of software systems (e.g., compilers, operating systems, computer architecture)
- Experience shipping software to users and maintaining high engineering standards
- Curiosity and a strong drive to learn and solve complex problems
- Collaborative mindset, with experience working across diverse teams
- Strong written and verbal communication skills
- Ability to shape technical direction, drive best practices, and support others through mentorship and leadership
- Interest in contributing to the quantum open‑source ecosystem
Even Better If
- Experience with a strongly typed language (e.g., C++ or Rust)
Benefits
- 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
