Battery Testing Engineer

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 by following the same legacy processes and traditions our predecessors did, instead, we are redefining 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 to delivering on our ambitious goal of having the VX4 in service by 2030.
As a Battery Test Technician, you will play a central role in preparing, running, and supporting a wide range of battery testing activities. This includes electrical, thermal, and mechanical performance testing, as well as environmental and safety validation in accordance with aerospace certification standards.
You will work closely with engineers and managers to build and maintain test rigs, calibrate and operate specialist equipment, and analyse data to verify system performance. The role will involve hands-on work with high-voltage battery assemblies and test hardware, alongside process improvement and documentation support.
Your work will directly contribute to the successful certification and launch of the VX4, helping to shape the future of sustainable aviation.
