Senior C++ Developer

You'll be working on the core software platform, solving complex engineering problems involving:

• Modern C++ development

• High-performance algorithms and data structures

• Concurrent and multithreaded programming

• Memory management and performance optimisation

• Cross-platform software development across Linux, Windows and macOS

• Designing and maintaining robust, scalable software at the heart of a globally deployed product

This is a hands-on engineering role where you'll spend your time solving difficult technical problems, improving performance and writing clean, maintainable code. You'll be joining a team of experienced software engineers, computer scientists and PhDs who are passionate about solving complex engineering problems.

We're Looking For

You'll ideally have experience with:

• Modern C++ (C++17 or later)

• Performance-critical or systems-level software

• Multithreaded and concurrent programming

• Strong computer science fundamentals, including algorithms and data structures

• Linux development

• Debugging and optimising complex software

Experience in any of the following would be advantageous:

• Database engines

• Compilers

• Distributed systems

• High-performance backend platforms

• Scientific or numerical computing

• Graphics, simulation or game engines

• Low-latency or real-time systems

Why Join?

• Work on a sophisticated C++ codebase deployed at global scale

• Join a highly experienced engineering team where technical excellence is valued

• Tackle genuinely challenging problems in performance, concurrency and software architecture

This role is ideal for engineers who enjoy understanding how software works beneath the surface, care about writing high-quality code, and want to work on technically challenging C++ systems

Avanti Recruitment is partnering with an innovative deep-tech software company developing high-performance software used by millions of devices worldwide. This is an opportunity to join a small team of exceptional engineers working on the company's core C++ platform. The work is technically demanding, with a strong emphasis on performance, correctness and elegant software design rather than rapid feature delivery.
