Senior Cell Engineer

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.

As an Senior Cell Engineer, you'll play a key role in qualifying commercial lithium‑ion cells for use in our next‑generation electric aircraft. Working closely with engineers, technicians, suppliers and research partners, you'll generate the evidence needed to support safe, high‑performance battery systems.

• Develop qualification methods for commercial lithium‑ion cells, covering electrochemistry, electrical testing and data analysis.
• Design test plans, communicate test requirements to engineers and technicians, and analyse and report results.
• Develop and optimise data analysis tools for electrical, safety and materials test data, including statistical analysis.
• Work with industrial and academic partners to plan and deliver cell testing and analysis activities.
• Generate and manage cell requirements and support associated verification and validation activities through testing, modelling and analysis.
• Support system‑level requirement verification across the battery programme.
• Support management of cell suppliers and contribute to our cell sourcing strategy.
• Contribute across the wider electrochemistry team, supporting performance, lifetime, safety, quality and future cell technology evaluation.

Essential

• Degree, MSc or PhD (or equivalent experience) in Electrochemistry, Chemical Engineering, Materials Science or a related discipline.
• Strong understanding of lithium‑ion cell electrochemistry, cell performance, degradation mechanisms and design trade‑offs.
• 1-2 years’ experience working with commercial lithium‑ion cells.
• Experience designing and analysing lithium‑ion electrical test programmes, including Design of Experiments (DoE).
• Strong experience analysing lithium‑ion cell data.
• Good understanding of how lithium‑ion cells integrate into larger battery systems.
• Ability to work independently while collaborating effectively across multidisciplinary engineering teams.
• Comfortable working in a fast‑paced, evolving environment with changing priorities.
• Strong analytical and problem‑solving skills with a proactive, hands‑on approach.

Desirable

• Experience with requirements management or systems engineering (e.g. FMEA, FTA).
• Familiarity with equivalent circuit models (ECM), thermal equivalent circuit models (TECM) or empirical lifetime modelling.
• Experience qualifying lithium‑ion cells for industrial applications such as electric vehicles or aerospace.
• Experience handling large datasets and developing data analysis pipelines.
• Hands‑on experience with electrical cell testing, materials characterisation or cell forensic analysis.
• Experience working with large‑scale cell suppliers.
• Aerospace industry experience.

We're on a mission. Where others see limits, we see opportunity, and we work king at Vertical isn't your average role but for those seeking a challenge, a flexible, supportive organisation and an incredible team; working here is an opportunity to do the best work of your career.
