Senior Embedded Software Engineer

Senior Embedded Software Engineer | Birmingham (Hybrid)

GTS Group have an exciting opportunity to join an industry disrupting organisation, based in Birmingham!

The role:

• Architect and build embedded software bridging microcontroller firmware (STM32, modern C++, MISRA) and higher-level supervisory systems
• Implement OCPP (1.6J–2.1), CAN, Modbus RTU and MQTT for vehicle and cloud comms
• Own things end to end: requirements → build → live site diagnostics
• Mix of work: ~60% new development, 30% integration/test, 10% in-service support

What you'll need:

• Strong C++ in resource-constrained embedded systems
• Hands-on with CAN/Modbus and MQTT/WebSockets
• RTOS or bare-metal background
• EVSE/OCPP experience is a plus, not a must — automotive, industrial control or energy backgrounds welcome

Why it's worth a look:

• Small team, so your decisions actually shape the product
• Infrastructure that matters, not another dashboard
• Hybrid: 2 days/week in Birmingham, genuine lab and site time
