Great ideas come from different minds. That’s why we bring together engineers, scientists, analysts, and creatives from every background – and give them the trust, tools, and freedom to make a difference. What connects us is the mission: solving meaningful problems and building capability that protects what matters most.
And as the challenges evolve, so do we – working on the technologies that will shape tomorrow, not just today.

Roke imagines a more secure world where technology protects, where engineers, consultants and business staff collaborate to protect what matters most to our clients.

Roke is a leader in the development of cutting‑edge technology solutions for the defence industry with clients spanning National Security, Defence and Intelligence areas. We work alongside our customers to solve their complex and unique challenges.

We are a friendly and flexible team with a culture of ‘time, trust and freedom’. We pride ourselves on listening to each other’s aspirations and accommodating wherever possible.

Roke is seeking an Embedded Software Engineer to design and implement efficient real time system software for a variety of developments in the domains of Position, Navigation and Timing (PNT), RF communication and sensors. This senior engineering role combines hands‑on detailed design with technical team leadership.

You will contribute innovation to and take ownership of software in the platforms for cutting‑edge electronics for defence and robust position, navigation and timing (RPNT) systems. You will use your design and simulation skills in projects from prototypes for urgent requirements at low TRL to development of new Roke EW products. Specific technology domains will include communication systems, radar systems, ground search systems, GNSS anti‑jam and anti‑spoof technologies such as array‑based directional antenna systems and extended long range navigation (eLORAN) systems.

You will join stimulating, collaborative and driven teams that offer you autonomy, challenge, and strong sense of purpose. In addition to your technical responsibilities there will be opportunities for leadership within the teams and in client engagements, in the initial discussions of requirements through technology demonstrations to customer acceptance test, delivery and support. The role may give the opportunity to work on client site, from the office, in shared work spaces or from home as necessary.

As an embedded software engineer your responsibilities could include:

• Capture of embedded software requirements, software design and test/ verification processes for efficient real time systems from R&D concept through to the full product development lifecycle
• The implementation of bespoke data processing and control schemes.
• Understanding and applying new and emerging technologies inclusive of RPNT Digital Signal Processing algorithm techniques
• Rapid prototyping for UOR requirements

• BEng/BSc or Master’s degree in an appropriate engineering or computer science related subject.
• Strong skill set in C and/or C++ for embedded development and associated operating systems
• Collaboration with cross‑functional teams to deliver project requirements, system design, and system test/integration phases and experience of modern Dev Ops practices
• Knowledge of latest System on Chip (SoC) devices, Software Defined Radio (SDR) platforms and open-source frameworks such as OpenCPI.
• Good understanding of Digital Signal Processing (DSP) algorithms and experience of modelling or simulation algorithms using MATLAB or Python.

• Awareness of security aspects related to embedded systems.
• Practical electronics design experience in hardware and associated FPGA firmware development.
• Knowledge of defence domains, such as Position, Navigation and Timing (PNT), Electronic Warfare, Sensor and Communication systems.
