Embedded Software Engineer

Salary: Up to £45,000 + Flexible Hybrid Working
Location: Birmingham (3 days onsite, 2 days WFH)

KO2's client, a pioneering technology company at the forefront of smart water management and operational efficiency, is looking for an experienced Embedded Software Engineer to join their innovative and collaborative engineering team in Birmingham.

This is an exciting opportunity to take ownership of embedded software design and development across a range of real-time, microcontroller-based systems. You'll work on products that have a genuine environmental impact - improving how critical resources are managed globally.

The Role

As an Embedded Software Engineer, you'll play a key role in the full development lifecycle, from concept through to testing and deployment.
You'll be responsible for developing efficient, reliable, and maintainable embedded code that interacts closely with custom electronics and sensor systems.

Key Responsibilities:

• Design, develop, and maintain embedded software in C/C++ for STM32 or ARM-based microcontrollers
• Implement and optimise applications running on RTOS platforms
• Work with serial communication protocols such as SPI, I2C, UART, and CAN
• Support board bring-up, debugging, and hardware/software integration
• Collaborate closely with hardware, firmware, and test engineers to deliver robust embedded solutions
• Participate in design reviews, code reviews, and continuous improvement initiatives

Skills & Experience

• Hands-on experience with embedded C/C++ development
• Proven experience developing firmware for STM32 or similar 32-bit microcontrollers
• Experience working with RTOS-based systems
• Proficiency in debugging and hardware bring-up using oscilloscopes, logic analysers, and JTAG tools
• Familiarity with serial communication protocols (SPI, I2C, UART, CAN)
• Comfortable working through the full development lifecycle - from concept to production

Desirable:

• Experience with low-power or sensor-based embedded systems
• Knowledge of analogue/digital circuit design and PCB-level debugging
• Exposure to version control and CI/CD tools (Git, Jira, etc.)

Why Join?

• Work on meaningful, environmentally impactful projects
• Be part of a growing, collaborative engineering team
• Enjoy hybrid working (typically 3 days onsite, 2 from home)
• Competitive salary and benefits, with opportunities for technical progression
