Our Mission At Vertical Aerospace, we are pioneering the way for electric aviation. The Valo, our eVTOL (electric, vertical, take-off and landing), ''zero emissions'' aircraft will set a new safety standard for how we will 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. Valo is targeting airliner-level safety certification in 2028 ahead of entering service with our airline and operator customers. What to Expect As an Advanced Mechanical Design Engineer (Thermal Runaway), you will join our Energy Storage team, working on one of the most critical safety challenges in electric aviation: thermal runaway prevention, mitigation and containment. You will play a key role in progressing thermal runaway testing, analysing test data, and translating insights into robust mechanical designs, simulations and qualification strategies. This role sits at the heart of our battery safety and certification journey. A typical day could involve supporting live thermal runaway tests, analysing results to inform next-stage design or simulation, collaborating with stress and manufacturing teams, or developing qualification strategies for novel materials and components. This role is well suited to an engineer
