Role: Senior Electronics Engineer - High Voltage Robotics Systems
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
This is a senior technical leadership role within AssetCool’s hardware team, responsible for the architecture and development of electronics deployed on robotic systems operating in high-voltage transmission environments.
You will lead the design of power, control and communication electronics for conductor-traversing robots and drone-deployed devices, and define the EMC and high-voltage validation strategies that ensure safe and reliable operation in harsh electromagnetic environments.
This is a hands-on role spanning the full product lifecycle from architecture and prototyping through validation, production and field deployment.
Key Responsibilities
Electronics architecture for live-line robotics
* Define system-level electronics architecture for robots operating on energised transmission lines
* Develop grounding, isolation and EMC strategies for high-electric-field environments
* Design resilient systems spanning power electronics, sensing, control and communications
PCB and power electronics development
* Lead design of multi-layer PCBs for motor control, power conversion, battery systems and sensor interfaces
* Ensure robust design for EMI/EMC, signal integrity, thermal performance and reliability
* Apply DFM/DFA/DFT principles to transition designs from prototype to production
High-voltage & EMC validation
* Define and execute EMC and high-voltage testing programmes with internal teams and test labs
* Lead root-cause analysis, mitigation and redesign following test and field feedback
Integration with robotics and drone platforms
* Collaborate with mechanical, embedded and robotics teams to integrate electronics into field-deployed systems
* Ensure reliability under vibration, temperature, humidity and high electric-field exposure
Production and quality
* Act as technical authority for electronics during manufacturing scale-up
* Support EMS partners, production test development and investigation of field returns
* Maintain documentation to support regulatory and compliance requirements
Technical leadership
* Provide mentorship and contribute to cross-functional design reviews and long-term electronics strategy
Required Skills & Experience
* Degree in Electronics/Electrical Engineering or related discipline
* 7+ years’ experience developing electronics for shipped products
* Strong analogue, digital and mixed-signal design skills
* Experience designing power electronics, motor control and battery-powered systems
* Strong understanding of EMI/EMC-aware PCB layout, grounding and noise mitigation
* Experience with common communication interfaces (CAN, RS485, Ethernet, SPI, I²C, UART)
* Experience developing electronics for harsh, outdoor or industrial environments
* Hands-on debugging using lab instrumentation and leading validation testing
Preferred Skills & Experience
Experience with EMC standards (e.g. IEC 61000) and environmental qualification
Experience with high-voltage-adjacent or safety-critical systems
Experience working with EMS partners and supporting production ramp-up
Familiarity with hardware configuration management and compliance processes
