Electronics Hardware Engineer

From the Mariana Trench, the deepest point on earth, to surging shorelines and anywhere in-between, we make the impossible possible through our continuous passion for innovation.
Our people design, engineer and manufacture technologies that are enabling our customers to discover, navigate, measure, detect and communicate in the toughest environment on earth: Our oceans.
Weve been actively developing the technology to make the oceans accessible for over 50 years and were only just getting started
At Sonardyne, we value different ways of thinking. Whether you think in code, patterns, systems, or steps, your unique perspective is important to us.

Are you an innovative Electronics Hardware Engineer with a passion for developing cutting-edge subsea technology? Join our Electronic Hardware team and contribute to the design and development of world-class underwater acoustic systems, data loggers, Doppler velocity logs, and more.

This is a fantastic opportunity for a skilled engineer who thrives in a hands-on environment and enjoys solving complex technical challenges.

As an Electronics Hardware Engineer, you will play a key role in designing, developing, and supporting the electronics and embedded firmware that power our subsea instruments.

If you join you will be:

• Designing digital (FPGA & MPU) and analogue electronics with a focus on low power consumption and low-noise performance

• Ensuring all designs meet EMC requirements, contributing to EMC testing and compliance

• Leading hardware design reviews and evaluating techniques to choose the best engineering solutions

• Developing embedded C and/or C++ applications for microprocessors

• Performing hands-on electronics and embedded software fault-finding

• Producing high-quality documentation to support development and future maintenance

• Staying ahead of industry trends, tools, and technologies

• Supporting continuous improvement of engineering processes

Some travel is required, including visits to our Plymouth trial site.

Were looking for a proactive engineer with strong problem-solving skills, excellent communication, and the ability to work independently or as part of a multidisciplinary team.

Ideally we would like:

• Expert in analogue and digital electronics design, including simulation and low-power techniques
• Competent in designing for EMC and understanding standards such as EN60945
• Competent in Altium for schematic design and basic PCB layout principles
• Competent in C programming; basic understanding of C++
• Strong documentation skills
• Hands-on fault-finding and production support experience
• Ability to collaborate effectively across teams
• 2:1 or above in Electronic Engineering, Electrical Engineering, or a related discipline

Leadership & Teamwork

While this role has no direct reports, you will be expected to mentor colleagues, guide design decisions, and uphold quality standards across engineering and production support.

Why Join Us?

• If you want to help deliver innovative subsea technologies that make a real impact in marine, defence, offshore, and science industries, this role offers the chance to work at the forefront of ocean engineering with a team that values quality, curiosity, and technical excellence.
