Expleo is a leading Global Engineering Services Provider with UK presence in 10 locations. We are seeking an Embedded Electronics Systems Integration Engineer.

We are looking for a proactive engineer with broad capability across electronics, embedded software, and system integration. Candidates with defence or aerospace backgrounds are of particular interest, with military, marine, or rail experience also considered valuable.

This position offers the opportunity to contribute directly to advanced defence technology, supporting the security of the UK and its allies. Ideal candidates will be collaborative, self‑motivated, detail‑focused, and methodical in their approach to problem solving

The Embedded Electronics Systems Integration Engineer will perform, but not be limited to, the following activities centred on system architecture, avionics integration, driver development, and laboratory de‑risking:

• →Support finalisation of the system architecture for communications and power
• →Identify required avionics equipment to fulfil the proposed architecture
• →Generate requirements specifications for any non‑COTS/MOTS equipment
• →Produce a system integration de‑risk plan
• →Conduct integration and compatibility testing of laboratory equipment to de‑risk the long‑term solution
• →Develop, document, and prove application drivers for imposed COTS/MOTS functionality
• →Develop, document, and prove communication translations (ETH T1/TX, MODBUS, CAN)
• →Liaise with SMEs across Electronics, Software, Systems‑Proving, and related disciplines
• →Project‑manage an aggressive de‑risk programme against an agreed plan
• →Demonstrate the complete system operating in the lab on representative hardware
• →Produce a future‑work report identifying remaining de‑risking activities
