We combine first-principles thinking with cutting-edge technology to build a radically better energy system.\nWe'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.\nWe'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.\nAs a Senior Test Engineer, you will play a critical role in ensuring Fuse’s hardware products and energy systems meet applicable regulatory, safety, and performance requirements throughout their lifecycle. You will work hands-on with prototypes and deployed systems, collaborating closely with hardware, firmware, software, and operations teams to translate regulatory requirements into practical, testable engineering outcomes.\nIn this role, you will be directly involved in design validation, certification, and end-of-line verification, navigating a broad regulatory landscape including electrical safety, EMC, grid connection standards, and environmental compliance.\nResponsibilities:\nPlan, set up, and execute hands-on validation, verification, and compliance tests on Fuse Energy hardware systems, both in laboratory environments and on live sites.\nPrepare systems for external certification and type testing, coordinating with notified bodies, test houses, and third-party laboratories.\nSupport in-field testing, commissioning, and acceptance activities at customer, partner, or pilot sites to validate safety, performance, and grid interoperability.\nExecute targeted test campaigns covering areas such as electrical safety (LVD), EMC, grid code compliance (e.g. G99/G100 and EU equivalents), functional safety, and environmental requirements.\nIdentify, analyse, and troubleshoot hardware, firmware, and system-level issues uncovered during testing, working closely with design and software engineers to drive corrective actions.\nDesign test equipment and software to perform automated test either in HIL testing or EOL verification at the production site.\nDevelop and maintain thorough test documentation, including test procedures, reports, evidence packs, and compliance dossiers for internal use and external audits.\nCommunicate test results, risks, and compliance status clearly to engineering, operations, and leadership teams, supporting informed technical and commercial decisions.\nContribute to continuous improvement of Fuse’s compliance, testing, and quality processes as products and deployments scale.\nRequirements\nBachelor’s degree or higher in Electrical Engineering, Electronic Engineering, or a closely related technical discipline.\nAt least 5 years of experience in a hardware test, compliance, regulatory, or certification-focused engineering role.\nStrong hands-on experience working with electrical or power-electronic systems in laboratory and/or field environments.\nProficiency with standard electrical test and measurement equipment, such as oscilloscopes, power analysers, multimeters, insulation testers, and data acquisition systems.\nExperience creating structured test plans, executing formal test procedures, and producing clear, high-quality technical documentation.\nWorking knowledge of relevant standards and regulations, such as LVD, EMC, grid connection codes, and related EU/UK directives (or a strong ability to learn them quickly).\nExcellent problem-solving and debugging skills, with a rigorous, detail-oriented approach to engineering work.\nAbility to work independently, manage multiple test activities in parallel, and operate effectively across lab, site, and external partner environments.\nBenefits\nCompetitive salary and an equity sign-on bonus\nBiannual bonus scheme\nFully expensed tech to match your needs\nPaid annual leave\nBreakfast and dinner allowance for office based employees","description_format":"text","description_chars":4295,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual
