My client is a design and technology consultancy specialising in IoT, embedded systems, and connected devices. They partner with global leaders in defence, medical, industrial, and energy sectors to design and deliver innovative, production‑ready technology. Their multidisciplinary team brings together electronics, firmware, software, mechanical design, and manufacturing expertise under one roof.

We are looking for a Senior Embedded Engineer to join a growing team in Bristol. This is a client‑facing role working directly with major global clients on multiple concurrent projects across diverse sectors. The work is varied, fast‑paced, and highly rewarding, offering the opportunity to develop advanced IoT and embedded systems from concept through to production.

This position represents a major career growth opportunity. As my client continues to expand, they are establishing firmware as a distinct and autonomous function within the business.

You’ll initially take ownership of the embedded function within a key project, then help define the future of the department shaping its processes, standards, and team as it grows.

It’s an ideal role for someone ready to take a significant step up in responsibility and leadership, with the long‑term goal of building and leading the embedded engineering capability within an innovative, forward‑looking company.
