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. We’re creating a fully integrated energy company: from developing solar, wind and hydrogen projects to real-time power trading and distributed energy installations. By selling directly to consumers, we cut out the middleman, lower costs and pass on savings to customers. But we’re not stopping there. We’re also building the Energy Network: a decentralised platform of smart devices that rewards users in Energy Dollars for electrifying their homes, shifting usage to off-peak hours, and helping balance the grid. This network strengthens grid stability - a critical foundation for scaling AI data centers and other energy-intensive industries.

- 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.
