Senior Software Engineer (C++/Linux)

Company

We're looking for an experienced software engineer to join a growing technology company developing software for specialist products used in highly demanding environments.

This is an application development role, focused on building robust C++ applications that run on Linux-based embedded platforms. It's not a firmware or electronics position, so we're looking for someone who enjoys developing software close to the hardware, without spending their days writing device drivers or low-level firmware.

Role

• Developing and enhancing applications written in C++
• Building software for Linux-based embedded and edge devices
• Working on performance-critical systems where efficiency and reliability matter
• Contributing to software architecture and technical decision-making
• Collaborating with a small team of experienced engineers to deliver high-quality products

Person

We're keen to speak with engineers who have experience in:

• Modern C++ development
• Linux application development
• Embedded Linux environments
• Software performance optimisation and memory management
• TCP/IP networking and communications protocols
• Developing software that interacts with hardware or runs on embedded devices

You'll be someone who enjoys solving complex technical challenges and takes pride in writing clean, well-engineered code.

Security Clearance Requirements

Due to the nature of the work, candidates must be eligible to obtain UK Security Clearance (SC).

To be considered, you'll typically need:

• A minimum of 5 years' residency in the UK
• A clear and consistent employment and address history during that period
• To hold one of the following:
  • A British passport, or
  • Indefinite Leave to Remain (ILR), or
  • A valid UK residency status that supports SC clearance eligibility

If you've built your career around C++ and Linux application development, and you're looking for a role where your software runs on real-world devices rather than in the cloud, I'd love to hear from you.
