System Engineer in Broughton

Position: Systems Engineer

Location: Livingston/Greater Edinburgh Area

Type: Full-time

SolarSub

SolarSub is a start-up on a mission to allow solar panels to thrive in the sun. The company has developed a patent-pending passive cooling technology to negate the impact of overheating on solar panel efficiency and lifespan, achieving a double-digit improvement in revenue. Initially, we are deploying in the floating solar market globally, unlocking more favourable project economics.

The company has secured Pre-Seed investment and has generated interest amongst OEMs and end-users. The technology has been validated at the University of Edinburgh, with infield trials ongoing in Dubai. We are now moving to our next stage of commercialisation, setting up field trials with strategic end-users.

We are seeking a systems engineer to join our team and support us in our technical development. This role offers a chance to contribute to driving a fundamental shift in renewable energy by maximising the efficiency of solar. The role is an important early hire into an early-stage start-up, and we are seeking an individual who would relish the opportunity to execute in an entrepreneurial environment and grow in a leadership capacity.

The role will be based in Livingston/Greater Edinburgh Area on a full-time basis, initially with flexibility for virtual working, but will require an increase in in-person presence in an office and lab facility.

Key Responsibilities

• Define and manage system requirements, interfaces, and architecture across all mechanical and electrical subsystems.
• Coordinate with mechanical design engineers to ensure technical outputs are aligned across the entire system.
• Incorporate structural requirements, electrical systems, mechanical component considerations, and fit-for-manufacturing principles into the design of the passive cooling system.
• Apply Design for Manufacture and Design for Assembly principles to reduce costs, mitigate risk and complexity, while improving reliability.
• Align designs with the requirements of manufacturers, EPCs, developers and environmental regulatory bodies.
• Contribute toward the development of appropriate verification test plans.
• Produce clear technical documentation and support IP development to capture and protect future innovations.

Ideal Candidate

• An engineering degree in mechanical, electrical, or other related fields.
• A track record of taking prototypes from mid-stage readiness to a commercially viable product that complies with customer requirements, industry standards and other stakeholder needs.
• Experience in system integration or multidisciplinary product development, preferably in renewable energy.
• An understanding of structural loads, cabling, electrical systems, and buoyancy/stability principles in floating systems is preferred.

Attributes

• Entrepreneurial mindset: A willingness to take initiative within the role and across the business as required.
• Team Player with the ability to execute autonomously: Thriving in a high-trust environment with high personal accountability, whilst understanding the amplifying value of the skills that surround you.
• Gritty and optimistic: An ability to thrive in problem-solving, taking setbacks in stride to propel the team forward.
• Low Ego: To underpin personal growth and contribute to creating a high-feedback environment, allowing the team to develop as a whole.
