About SolarSub
SolarSub is a start-up on a mission to enable 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 global floating solar market, 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 and has progressed through field testing. We are now preparing trials with strategic end-users and partners in Spain, Scotland, and Singapore.
We are seeking a Verification & Validation 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. 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 at the Salter Centre in Loanhead, Edinburgh on a full-time basis, with regular in-person office and lab work and international travel.

- Own verification and validation (V&V) across laboratory, pilot, and field trials, translating requirements into clear test objectives and acceptance criteria.
- Design test set-ups, fixtures, and instrumentation layouts using computer-aided design (CAD), integrating monitoring and data acquisition (DAQ) to generate repeatable engineering evidence.
- Create and manage the test programme, procedures, methodology, and standards, coordinating internal work and specialist third-party testing.
- Analyse test, simulation, and pilot data, conduct root cause analysis (RCA), and translate results into clear product and design decisions.
- Lead reliability testing for commercially important long-term risks, namely, durability, degradation, and failure modes, using Failure Modes and Effects Analysis (FMEA).
- Develop long-term test procedures and quality control (QC) methods for product development, manufacture, and deployment.
- Maintain clear test documentation, traceability, and reporting, working closely with Product & Performance on performance goals.
Ideal Candidate
- An engineering degree in mechanical, electrical, materials, energy, or another related field.
- An understanding of FEA and CFD is advantageous.
- Experience planning and executing verification, validation, or reliability programmes for physical products, ideally from prototype and laboratory testing through to field deployment.
- Practical capability in test design, instrumentation, data analysis, and root-cause investigation, with the ability to turn results into sound engineering decisions.
- Experience of working with test standards, quality methods, and external laboratories is preferred; renewable-energy, solar, floating-system, or outdoor testing experience would be advantageous.
