Fuse Energy is an energy startup on a mission to make energy abundant and affordable, fast. We combine first-principles thinking with cutting-edge technology to build a radically better energy system.
We've raised over $200M from top-tier investors including Balderton, Lakestar, Accel, Creandum, Lowercarbon, Ribbit, 20VC, Hummingbird and Collaborative Fund, alongside strategic angels including Nico Rosberg and GPs behind Meta, Revolut, Spotify and Uber.
We're building a fully integrated energy company: developing our own solar, batteries and other generation projects, building our own hardware, improving and developing grid infrastructure, trading power in real time, using AI across the business, and installing distributed energy in homes. By selling directly to consumers we cut out the middleman, lower costs and pass the savings on to our customers.
We're hiring a versatile Electronics Design Engineer to develop the core electronics behind our plug-and-play solar products. The role focuses on designing robust, scalable electrical systems for safe, efficient and reliable renewable energy hardware.
Responsibilities
- Own end-to-end electrical development, including requirements definition, specification, design execution, simulation, schematic capture, PCB layout, DFM iteration, board bring-up, system integration, and validation
- Design and develop electronics for renewable energy systems, including power conversion, sensing, control, and communications functions
- Collaborate closely with firmware, mechanical, controls, PCB layout, program management, validation, and manufacturing teams to deliver high-performance hardware
- Debug hardware issues and system-level interactions in a fast-moving, multidisciplinary development environment
- Produce clear and thorough technical documentation, including design requirements, calculations, test plans, validation results, and design reviews
- Support prototype builds, industrialization, supplier engagement, and production ramp activities
- Rapidly iterate designs as requirements evolve and product features mature over time
Requirements
- Strong understanding of power electronics and circuit design, including dc/dc converters, inverters, battery-powered systems, power switching devices, gate drivers, magnetics, and loss modeling/calculation
- Strong understanding of analog and digital circuit design, including microcontrollers, signal conditioning, common communications interfaces, component selection, and thermal/power dissipation considerations
- Experience with PCB design and layout for mixed power and signal systems, including minimizing parasitics and designing for EMI/EMC performance
- Experience with circuit board design tools, ideally Altium Designer
- Proficiency with lab equipment such as oscilloscopes, electronic loads, signal generators, LCR meters, and power analyzers
- Experience with hardware bring-up, validation, debugging, and root-cause analysis
- Familiarity with modeling and simulation tools such as LTspice, PLECS, or similar
- Basic scripting or programming ability, ideally in Python or MATLAB
- Basic knowledge of embedded systems, PWM, and control concepts for power conversion
- Experience supporting products through manufacturing and high-volume production is a plus
- Bachelor’s, Master’s, or PhD in Electrical Engineering or a related field, or equivalent practical experience
