Do you want to work with the 15th fastest-growing startup in Europe? If so, you’re in the right place.
AssetCool is one of Europe’s fastest-growing startups, building the fastest path to more power on the grid.
We’re tackling one of the most urgent challenges in the global energy transition: grid congestion. Electricity demand is rising fast; driven by electrification, AI and data centres. While traditional grid upgrades take years, demand exists today. The grid isn’t ready.
AssetCool delivers robotic grid upgrades that physically increase the capacity of existing transmission lines by up to 30%, without rebuilding infrastructure. Using advanced robotics and proprietary photonic coatings, we unlock data-centre-scale capacity in weeks to months, not years and at a fraction of the cost and disruption of conventional approaches.
Our technology goes beyond capacity. We reduce losses, prevent corrosion, cut corona noise and generate high-value operational data that supports smarter grid operation and maintenance. Our systems are already deployed globally, and we just raised a big funding round from leading energy and climate investors.
AssetCool is one of the most innovation-driven companies in the UK energy sector and we’re scaling fast! If you’re ambitious, mission-driven and excited to work on real deployments that strengthen the industry that really matters, AssetCool is where you can make it happen.
Role Overview
As a Test & Validation Engineer, you play a critical role in ensuring the safety, reliability, and performance of our CapacityN robotic platforms. You will design and execute test plans, build test rigs, collect and analyse data, and provide clear feedback to design teams. This role requires strong hands-on skills, analytical thinking, and cross-disciplinary knowledge across mechanical, electrical, and software systems.
