Job Description

We are working with a global manufacturer of safety‑critical electronic instrumentation used in regulated, real‑world environments where reliability and accuracy are essential.

This is a hands‑on firmware role suited to someone with solid low‑level embedded experience who enjoys working close to the hardware, developing and maintaining real‑time firmware on 32‑bit microcontrollers, integrating sensors and communication protocols, and contributing to products from early development through to production alongside hardware and systems engineers.

Key Responsibilities

• Develop and maintain embedded firmware in C/C++ for safety‑focused electronic products. Build real‑time firmware on 32‑bit microcontrollers in an RTOS environment. Integrate sensors and communication interfaces (UART, SPI, I²C, Modbus). Write and debug low‑level drivers and hardware abstraction layers. Support board bring‑up and troubleshooting with hardware and systems teams. Contribute to reliable releases through testing, validation, and good engineering practices.

Essential Requirements

• Significant professional experience developing embedded software in C and C++ for production systems.
• Strong hands‑on experience with embedded Linux and real‑time operating systems.
• Deep understanding of low‑level device programming, hardware interfaces, and real‑time data handling.
• Experience integrating embedded software with FPGA‑based systems, including register‑level communication and performance optimization.
• Proven ability to take ownership of complex technical work and drive it through multiple development phases.

Desirable Requirements

• Experience developing firmware for low‑power or resource‑constrained embedded systems.
• Familiarity with regulatory or compliance‑driven development environments and structured testing practices.
