Electronics Engineer - Climate Tech Start-Up

Want direct contact with senior management, more technical ownership, and a role that contributes to solving global energy challenges? This is for you. What’s in it for me? This is an opportunity to join a maturing start-up developing a new generation of high energy density supercapacitors—technology with the potential to transform how clean energy is stored and delivered. Backed by a strategic collaboration with one of the world’s largest private energy companies, and based in state-of-the-art labs just outside Cambridge, this role comes with the chance to join as the second electronics engineer, helping shape the development of novel energy storage technology. What will I be doing? You’ll work closely with senior management to define the BMS road-map and bring new ideas to life—from circuit design and embedded systems to building and testing prototype boards. The role also includes contributing to broader research projects focused on improving energy cell performance and supporting new commercial prototypes. The tech stack is broad and evolving, including STM32/ARM Cortex systems, SMPS, DC-DC converters, and communication protocols like SPI, I2C, and CANbus. Tools used include KiCAD, LTSpice, and MATLAB, with hands-on lab work across design, soldering, and debugging. This is a role offering deep technical exposure, meaningful input into product direction, and the chance to work on technology with global impact. You’d be joining at a formative stage, where your contribution directly influences outcomes. There\’s strong support for learning, high visibility, and clear progression opportunities for those who want to lead projects or build deep expertise. You’ll need a solid grounding in power electronics and embedded systems, practical experience with PCB design and prototyping, and a genuine interest in energy storage or battery systems. You’ll also need to be comfortable working full-time on-site (with some flexibility) at the company’s Cambridge-area facility. If you’re looking for a role where you’ll be trusted to solve problems, push your skills, and contribute to a clean energy mission that matters—I’d love to chat. What do I do next?
