Their ambitious mission is to deliver a terawatt of renewable energy rapidly, achieved through a combination of first-principles thinking and advanced technology. The company is building a fully integrated energy ecosystem, encompassing the development of solar, wind, and hydrogen projects, alongside real-time power trading and distributed energy installations. Fuse Energy differentiates itself by selling directly to consumers, thereby reducing costs and passing savings onto customers. Furthermore, they are developing the 'Energy Network,' a decentralized platform featuring smart devices that reward users with 'Energy Dollars' for electrifying their homes, optimizing energy usage, and contributing to grid stability. This network is crucial for supporting the increasing energy demands of AI data centers and other energy-intensive industries.

Job Description

Fuse Energy is at the forefront of the renewable energy revolution, committed to rapidly scaling sustainable power solutions. We are building a comprehensive energy infrastructure, from project development to consumer-facing energy systems.

As a Senior Test Engineer, you will be pivotal in ensuring our hardware and energy systems meet stringent regulatory, safety, and performance standards. You will engage directly with prototypes and operational systems, collaborating across hardware, firmware, software, and operations teams to translate complex regulatory requirements into actionable, testable engineering outcomes.

This role involves hands-on design validation, certification processes, and end-of-line verification, navigating a wide array of regulations including electrical safety, electromagnetic compatibility (EMC), grid connection standards, and environmental compliance.

  • 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 & Perks

  • 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
