Job description

Graduate / Junior Software Engineer C++

Location: Berkshire (on-site)

Salary: Up to £40k, + benefits, inc. bonus, pension, PMI etc.

This role is for a junior or graduate C++ engineer who wants to learn how real, production systems are built.

You’ll work on performance-focused software that processes very large data files. It’s not a real-time environment, but efficiency, memory usage, and clean design matter. You’ll write new C++ code, improve an existing codebase, and learn how commercial products are engineered properly.

The team is small and technically strong. You won’t be thrown in at the deep end, but you will be expected to think for yourself, take ownership of problems, and grow your skills over time. This isn’t a corporate ladder role it suits someone motivated by technical contribution and depth, not job titles.

Looking For

• Strong fundamentals in C++
• Interest in performance-focused systems
• Willingness to work with existing / legacy code
• Qt experience helpful but not essential
• Engineering, Physics, Maths or similar background preferred

Why Join

• Real C++ engineering, not framework glue
• Exposure to complex, data-heavy systems
• Direct access to experienced engineers
• Long-term technical development
