About the role

  • Develop and implement test plans that align with product development phases, regulatory requirements, and project timelines for power conversion systems and HIT-related hardware.
  • Plan and execute comprehensive testing activities including but not limited to: PCB functional tests, design proving tests, system integration tests, environmental tests, and FAT.
  • Conduct hands-on testing using laboratory equipment to validate, characterise, or troubleshoot our hardware products.
  • Create and maintain test documentation including test plans, test procedures, test specifications, and detailed technical reports.
  • Perform electrical safety, EMC, and compliance testing for high-voltage and high-power systems, ensuring alignment with relevant standards (LVD, EMC, grid connection codes, CE, UL) and preparing systems for external certification.
  • Troubleshoot and diagnose hardware and system-level issues uncovered during testing, working closely with mechanical, embedded software, and systems engineers to identify root causes and support corrective actions.
  • Occasionally support field testing and commissioning activities at customer, partner, or pilot sites, ensuring that systems operate safely and meet performance specifications in real-world grid environments.
  • Lead and maintain high laboratory standards, including organisation, housekeeping, data management, inventory control, and equipment calibration, in collaboration with the leadership team, to uphold EHS compliance.
  • Actively participate in design reviews and technical discussions across the multidisciplinary hardware team, providing test perspectives on design decisions, manufacturability, and validation feasibility.
  • Develop and optimise test tooling and automation where appropriate to improve test efficiency, repeatability and coverage whilst maintaining rigor.
  • Ensure test cases are developed based on project scope and design requirements, and maintain testing reports and evidence for quality and audit purposes.
  • Champion continuous improvement in testing processes, suggesting enhancements to increase efficiency and effectiveness as our product portfolio scales.

Requirements

  • Strong hands-on experience in hardware testing, validation, or verification roles within electronics, power electronics, or related engineering environments.
  • Experience working in a laboratory environment, with a strong understanding of standard laboratory practices and procedures.
  • Proficiency with standard electrical test and measurement equipment: oscilloscopes, power analysers, multi-meters, insulation testers, power supplies, load banks, and data acquisition systems.
  • Ability to read and interpret complex technical drawings, wiring diagrams, PCB schematics, and system block diagrams.
  • Demonstrated ability to troubleshoot and diagnose faults down to component level.
  • Experience testing power electronics converters (AC/DC, DC/AC, DC/DC) or inverter systems would be useful.
  • Understanding of DFT principles.
  • Experience with environmental or reliability testing (vibration, thermal cycling, humidity, EMI).
  • Working knowledge of high-voltage and high-power system testing (ideally experience with systems up to 1 kV).
  • Familiarity with relevant standards and regulations: LVD, EMC, electrical safety, and grid connection codes (or strong ability to learn quickly).
  • Knowledge of quality management and compliance frameworks (ISO 9001, ISO 17025) is beneficial.
Benefits
  • Employee Option Plan: You get equity in IONATE, so as we succeed so do you.
  • Private Medical & Dental Insurance: From day one, we provide you with full, comprehensive private medical and dental cover through Bupa. You also have the option to add any dependents to your cover. Please ask us for more details.
  • Company pension: a flexible, and sustainable pension product to help you plan for your future.
  • Career Development: It’s important to us that you have the opportunity for ongoing professional development and career growth. You will receive an annual budget for professional development and work with your team to set and reach goals every year.
  • Flexible working schedules: You will have the flexibility for work-from-home arrangements. Talk to us at the application stage about this.
  • Cycle to Work Scheme: Low carbon travel is important for everyone, so we have in place a cycle scheme to help you purchase a bicycle.
  • Slow travel: We believe in a low carbon future, so if you wish to travel by a lower carbon method – but it takes much longer than flying - we will give you an extra 2 slow travel days per year.
