About Asset Cool

Do you want to work with the 15th fastest-growing startup in Europe? If so, you’re in the right place.

Asset Cool 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.

Asset Cool 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.

Asset Cool 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, Asset Cool is where you can make it happen.

As the High Voltage Systems Engineer, you will be our internal subject matter expert for all high‑voltage requirements and experimental designs. You will play a pivotal role in ensuring that our robotic and drone platforms are not only functional but fully live‑line capable. You will lead the design of proof‑of‑concept experiments for our coatings and robotic systems, providing critical design input to ensure our technology operates safely and reliably in energised high‑field environments.
