Senior C++ Software Engineer - Scientific Software
Location: Glasgow, hybrid WFH (50/50 split between home and office)
Salary: Up to £65,000 DOE
KO2's client develops advanced cheminformatics software. Their software helps scientists understand and work better with chemical data. They're looking for an experienced Senior C++ Software Engineer to join their small, growing team in Glasgow. You'll modernise their core C++ codebase and turn complex scientific algorithms into robust, high-performance code.
The company is international and close-knit. The Glasgow team works closely with colleagues in small offices in Germany and France, so you'll be part of a collaborative, multicultural engineering group.
You'll work closely with chemistry subject-matter experts and implement their algorithms using sound design patterns and modern C++. You'll be one of the main code reviewers, protect the quality and consistency of the architecture, and mentor junior developers as they continue to grow.
Key responsibilities
- Maintain and modernise a legacy C++ codebase, migrating it gradually to modern C++
- Implement new cheminformatics algorithms specified by the SMEs
- Review algorithm specifications for feasibility and clarity before implementation
- Act as a primary code reviewer, protecting the team's architectural consistency and code quality
- Own the test strategy for your work, covering unit and integration tests, edge cases and regression protection
- Maintain the CMake build system and related Linux tooling
- Mentor junior developers on clean code, architecture and design patterns
- Work with colleagues in Glasgow, Germany and France
Essential skills and experience
- Significant commercial modern C++ experience, 17 onwards ideally.
- An architectural mindset, with OOP, SOLID principles and design patterns as part of your everyday work
- Confidence applying modern idioms to legacy code you didn't write
- Strong code review skills. You give thorough, constructive feedback and can spot subtle logic errors and design drift
- A solid understanding of concurrency, including writing, debugging and reasoning about multithreaded code, synchronisation and data races
- Experience with the Linux development toolchain: CMake, GCC/Clang, gdb, and dynamic linking (RPATH, SONAME)
- Familiarity with static and runtime analysis tools such as clang-tidy, Valgrind and sanitisers
- Experience of AI-assisted development, such as using Claude Code and directing coding agents on architectural decisions
- Implementing algorithms from specifications, and reasoning about their efficiency and complexity
- Network programming (TCP/IP and sockets)
- Python, and testing frameworks such as pytest and Catch2
- Docker and containerised build environments
What's on offer
- A competitive salary, depending on experience
- Flexible hybrid working, split 50/50 between home and the Glasgow office
- A small, growing Glasgow team that you can help shape
- Working with international colleagues in Germany and France
- Challenging, meaningful work on scientific software
- A senior role with real influence over architecture and code quality
