Embedded Firmware Engineer

Salary: £45,000–£55,000 | Fully On-site | Worcester

The Opportunity

An opportunity has arisen for a Junior Embedded Firmware Engineer to join an established engineering and manufacturing business developing, building and maintaining electronic products.

This role would suit an engineer with a couple years of industry experience who enjoys practical engineering, working close to hardware and seeing their firmware brought to life in real products.

You'll contribute to firmware development while gaining exposure to electronics design, testing and product development within a hands‑on engineering team.

The business is open to engineers with different levels of experience and is looking for someone with a solid technical foundation, a practical approach and the ability to make an impact.

What You'll Be Doing

• Developing and maintaining embedded firmware using C.
• Working with microcontrollers, ideally PIC and/or ESP32 platforms.
• Supporting firmware development for connected devices, telemetry and low-power applications.
• Working alongside engineers on electronic hardware and PCB-related development.
• Testing, debugging and troubleshooting firmware and electronic systems.
• Supporting RF testing, radio communications and product compliance activities where required.
• Contributing to the development, manufacture and ongoing maintenance of electronic products.

What We're Looking For

• Experience developing embedded firmware using C.
• Exposure to microcontroller‑based systems, ideally PIC, ESP32 or similar platforms.
• A good understanding of embedded systems and how software interacts with hardware.
• A practical, hands‑on approach to engineering and problem‑solving.
• An interest in electronics hardware, PCB design or working directly with electronic products.
• Good debugging and troubleshooting skills.
• A willingness to learn, take ownership and contribute across different areas of engineering.

Experience with any of the following would be advantageous:

• PCB design and electronic hardware development.
• Automotive electronics, telemetry or low‑power systems.
• RF, wireless communications or radio frequency testing.
• EMC, regulatory compliance or product verification.

Please Note: We cannot offer sponsorship for this role
