Fuse Energy is a renewable energy startup backed by $170M in funding from top-tier investors including Multicoin, Balderton, Lakestar, Accel, and others. The company is building an integrated energy platform spanning solar, wind, and hydrogen projects, real-time power trading, distributed energy installations, and a decentralized smart-device network to optimize grid stability and support energy-intensive industries like AI data centers.
As Senior Hardware Test Engineer, you will ensure Fuse's hardware products and energy systems meet regulatory, safety, and performance requirements throughout their lifecycle. You will work hands-on with prototypes and deployed systems, collaborating with hardware, firmware, software, and operations teams to translate regulatory requirements into practical, testable engineering outcomes.
Key responsibilities include:
- Plan, set up, and execute validation, verification, and compliance tests on hardware systems in laboratory and live-site environments
- Prepare systems for external certification and type testing, coordinating with notified bodies and third-party laboratories
- Support in-field testing, commissioning, and acceptance at customer, partner, and pilot sites
- Execute test campaigns covering electrical safety (LVD), EMC, grid code compliance (G99/G100 and EU equivalents), functional safety, and environmental requirements
- Identify, analyze, and troubleshoot hardware, firmware, and system-level issues; drive corrective actions with design and software teams
- Design test equipment and software for automated testing (HIL and EOL verification)
- Develop and maintain test documentation, procedures, reports, evidence packs, and compliance dossiers
- Communicate test results, risks, and compliance status to engineering, operations, and leadership
- Contribute to continuous improvement of compliance, testing, and quality processes as the company scales
Requirements:
- Bachelor's degree or higher in Electrical Engineering, Electronic Engineering, or closely related technical discipline
- At least 5 years of experience in hardware test, compliance, regulatory, or certification-focused engineering
- Strong hands-on experience with electrical or power-electronic systems in laboratory and/or field environments
- Proficiency with standard electrical test and measurement equipment (oscilloscopes, power analysers, multimeters, insulation testers, data acquisition systems)
- Experience creating structured test plans, executing formal test procedures, and producing clear technical documentation
- Working knowledge of LVD, EMC, grid connection codes, and EU/UK directives (or strong ability to learn quickly)
- Excellent problem-solving and debugging skills with rigorous, detail-oriented approach
- Ability to work independently, manage multiple test activities in parallel, and operate effectively across lab, site, and external partner environments
