Job description

At Vertical Aerospace, we are pioneering the way for electric aviation. The VX4, our eVTOL (electric, vertical take-off and landing), zero-emissions aircraft will set a new safety standard for how we navigate the sky. We won't realise our mission following the same legacy processes and traditions our predecessors followed. Instead, we want to redefine aerospace best practices. We are growing quickly from a prototype business to a scaling SME, and the next few years will be critical to our success and delivering on our ambitious goals of having the VX4 in service by 2030.

What to Expect

As an Advanced Battery Test Engineer, you will join our dynamic Energy Storage team, which is responsible for developing a best-in-class primary energy storage solution for the VX4 aircraft. Within this team, the Battery Test function plays a vital role in supporting both product development and certification of our high-voltage battery assemblies. You will be at the heart of this effort, delivering testing services for performance validation, safety sign-off, and aircraft certification.

What You’ll Do

• Deliver mechanical, thermal, and electrical battery testing, including electrical cycling, abuse testing, vibration and IP rating tests, BMS and battery cooling system testing, EMC and HIRF testing, and testing in accordance with DO-160, DO-311A, and UN38.3
• Develop and implement test procedures, technical documentation, and formal test reports
• Own test methodology and support development of new internal standards
• Lead test operations in our labs and at third-party sites, including travel where needed
• Design and deliver electrical systems to support HV and LV test configurations
• Support facility development and new equipment integration, including calibration
• Contribute to risk assessments and ensure safe working practices
• Mentor technicians and junior engineers, helping raise internal standards
• Liaise with simulation teams and certification authorities to ensure test data is robust and traceable
• Support procurement and third-party engagement for equipment and services
• Participate in post-test inspections, live HV work, and instrumentation setup

Minimum Skills and Experience

• 4+ years in a high-tech test environment, ideally in aerospace or EV battery testing
• Hands‑on experience with electrical, mechanical, and environmental test systems
• Demonstrated ability to lead and deliver hardware testing projects
• Familiarity with CAN systems and data loggers: Dewesoft, Vector (CANalyzer/CANoe), LabVIEW, PICO
• Experience with lab equipment: battery cyclers, shaker tables, climatic chambers, cooling carts, etc.
• Strong organisational, communication and documentation skills
• Experience mentoring or training junior staff

Desirable

• Experience with HV live working and pre‑/post‑test instrumentation
• Familiarity with battery test standards for certification
• Background in defining equipment requirements and contributing to facility development
• Proficiency in CAD tools such as CATIA or equivalent
• Experience supporting third‑party test campaigns

Our People Matter – Benefits

• 26 days holiday, plus bank holiday
• 5 extra days per year to buy (or sell)
