Job description

Director (Electronics Engineer) at Spark Product Innovation Ltd

Company Overview

We are an ISO9001-certified product design consultancy working across mechanical, electronic and software disciplines to deliver innovative solutions that meet our clients’ needs. Integration and understanding across these domains is central to how we work and a key driver of our success.

Our team has deep expertise in high-speed digital electronics, analogue design and power electronics, together with embedded firmware, microprocessor software, digital signal processing and FPGA-based system integration.

Why Join Us?

You’ll be part of a highly skilled and collaborative engineering team where technical curiosity and practical problem‑solving are valued. We work on varied and genuinely interesting projects across multiple market sectors, meaning no two designs are the same. You’ll have the autonomy to take ownership of your work, influence technical direction, and see designs through from concept to production. We offer a supportive environment, opportunities to broaden your skillset, and the chance to make a meaningful impact on real products.

Role

Due to the growth of the business, we are now seeking an additional electronic design engineer to become part of our highly talented team based in the Bristol & Bath Science Park.
