Senior Hardware Test Engineer

Fuse Energy is a forward-thinking renewable energy startup on a mission to deliver a terawatt of renewable energy - fast.

We're combining first-principles thinking with cutting-edge technology to build a radically better energy system. We raised $170M from top-tier investors including Multicoin, Balderton, Lakestar, Accel, Creandum, Lowercarbon, Ribbit, Box Group and strategic angels like Nico Rosberg, the Co-Founder of Solana and GPs behind Meta, Revolut, Spotify, Uber and more.

As 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.

Responsibilities

• Plan, set up, and execute hands-on validation, verification, and compliance tests on Fuse Energy hardware systems, both in laboratory environments and on live sites.
• Prepare systems for external certification and type testing, coordinating with notified bodies, test houses, and third-party laboratories.
• Support in-field testing, commissioning, and acceptance activities at customer, partner, or pilot sites to validate safety, performance, and grid interoperability.
• Execute 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.
• Identify, analyse, and troubleshoot hardware, firmware, and system-level issues uncovered during testing, working closely with design and software engineers to drive corrective actions.
• Design test equipment and software to perform automated test either in HIL testing or EOL verification at the production site.
• Develop and maintain thorough test documentation, including test procedures, reports, evidence packs, and compliance dossiers for internal use and external audits.
• Communicate test results, risks, and compliance status clearly to engineering, operations, and leadership teams, supporting informed technical and commercial decisions.
• Contribute to continuous improvement of Fuse’s compliance, testing, and quality processes as products and deployments scale.

Requirements

• Bachelor’s degree or higher in Electrical Engineering, Electronic Engineering, or a closely related technical discipline.
• At least 5 years of experience in a hardware test, compliance, regulatory, or certification-focused engineering role.
• Strong hands-on experience working with electrical or power-electronic systems in laboratory and/or field environments.
• Proficiency with standard electrical test and measurement equipment, such as oscilloscopes, power analysers, multimeters, insulation testers, and data acquisition systems.
• Experience creating structured test plans, executing formal test procedures, and producing clear, high-quality technical documentation.
• Working 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).
• Excellent problem-solving and debugging skills, with a rigorous, detail-oriented approach to engineering work.
• Ability to work independently, manage multiple test activities in parallel, and operate effectively across lab, site, and external partner environments.

Benefits

• Competitive salary and an equity sign-on bonus
• Biannual bonus scheme
• Fully expensed tech to match your needs
• Paid annual leave
• Breakfast and dinner allowance for office based employees
