Software development in C++ and Rust for low latency transactions

This company creates ultra-high-speed FPGA-based hardware and highly optimised software for specialised applications requiring maximum performance. Due to continued growth, they are seeking an experienced C++ software engineer to join their Cambridge-based development team.

In this senior engineering role, you will help shape the software component of their system. Written in C++ and increasingly in Rust, this code runs in a Linux environment, and is responsible for control functionality and oversight of the hardware. You would be contributing to its design, development, test, and deployment throughout the software development lifecycle. Aspects you might typically be involved in include concurrency, threaded programming, communications protocols, and maximising performance by leveraging CPU and memory architectures.

You may well also be called upon to impart your knowledge to less experienced engineers and to collaborate with colleagues and stakeholders, including from non-engineering specialisms.

You will need:

  • A good degree in computer science or related discipline from a well-respected university.
  • Demonstrably excellent software design and implementation skills, including strong skills in C++ and at least an interest in using Rust.
  • A good understanding of Dev Ops techniques.
  • Good communication and team-working skills and an analytical approach to problem solving.
  • Full, existing, and unrestricted UK work permission.

This is a great opportunity for an accomplished Senior C++ Developer with a penchant for thinking outside the box to push the limits of highly optimised code. Whilst highly profitable, this company was founded primarily with altruistic aims in mind - a philosophy that includes taking good care of their employees and providing a friendly and supportive workplace culture. They offer a competitive compensation package including performance-based bonuses.

Hybrid working is available for up to two day per week with the remainder being based at their Cambridge offices.
