Job description

Are you an experienced software developer who loves building practical solutions on embedded hardware? Want to work closely with end‑users and see the real‑world impact of your code? Join our National Security & Defence team, where you'll design and deliver mission‑critical software using platforms like ESP32, Raspberry Pi, and ARM‑based microcontrollers (e.g., Zero, Pico). You'll work with Python and C++ to solve operational problems directly alongside our customers, typically on‑site 4 days per week. This is a hands‑on role for engineers who enjoy low‑level work, problem solving, and creating robust tools in challenging environments.

Responsibilities

• Develop bespoke software solutions on embedded platforms (ESP32, Raspberry Pi, ARM).
• Write and maintain code in Python and/or C++, often interfacing directly with hardware.
• Work with communication protocols to control and integrate peripheral devices.
• Perform testing and debugging, both in the lab and at customer sites.
• Collaborate with cross‑functional teams to refine requirements and implement features.
• Occasionally support system integration and deployment of hardware/software stacks.
• Engage with users to understand operational needs and adapt your solutions accordingly.
• Contribute to technical documentation and version control (Git).
• Support team knowledge sharing and mentor less experienced developers when appropriate.

Qualifications

• Experience in hands‑on software development.
• Strong proficiency in C++ and/or Python.
• Experience coding for embedded systems (e.g., ESP32, ARM Cortex based boards).
• Familiarity with low‑level hardware interfacing, including serial comms, GPIO, USB, or SPI/I2C.
• Comfort working in Linux development environments.
• Strong problem‑solving skills and attention to detail.
• Ability to adapt quickly to new hardware, tools, and use cases.
• Familiarity with unit testing, debugging tools, and Git‑based workflows.

Desirable

• Experience with security‑focused projects (e.g., Government, MoD).
• Exposure to cryptography and secure audio/data transport.
• Knowledge of Bluetooth, Ultra Wideband, or other wireless protocols.
• Familiarity with USB device drivers or USB communication.
• Experience with RTOS or bare‑metal development environments.

Education & Qualifications

• Degree in Computer Science, Electrical Engineering, or related field preferred.
• Professional membership of BCS or IET is a plus.

Benefits

• Pay Range: £47,500.00–£60,900.00 (general guideline; subject to change).
• Pension, share options, car leasing, free parking, cycle scheme.
• Private medical insurance.
• 33 days annual leave (incl. public holidays), with buy/sell options.
• Flexible benefits: life assurance, gym memberships, health plans.
• Work‑life balance: 37.5‑hour week + up to 2 TOIL days per month.
• Learning & development: TechX Academy, unlimited e‑learning, career mobility.

If you want to work on real‑world systems, close to the mission, and in a role where your code directly impacts outcomes, we'd love to hear from you.

Commitment to Diversity.
