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.
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
- Document your implementations clearly
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
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

Your very own career expert that helps elevate your application to the next level.
Desirable Skills
- 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
- Maintaining CI/CD pipelines
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
