As a Senior Cell Engineer at Vertical Aerospace, you will qualify commercial lithium-ion cells for use in the Valo eVTOL aircraft. You will develop qualification methods, design test plans, analyse data, and work with suppliers and research partners to generate evidence for safe, high-performance battery systems.

Responsibilities

Developing qualification methods for commercial lithium-ion cells, covering electrochemistry, electrical testing and data analysis.
Designing test plans, communicating test requirements to engineers and technicians, and analysing and reporting results.
Developing and optimising data analysis tools for electrical, safety and materials test data, including statistical analysis.
Working with industrial and academic partners to plan and deliver cell testing and analysis activities.
Generating and managing cell requirements and supporting associated verification and validation activities through testing, modelling and analysis.
Supporting system-level requirement verification across the battery programme.
Supporting the management of cell suppliers and contributing to our cell sourcing strategy.
Contributing across the wider electrochemistry team, supporting performance, lifetime, safety, quality and future cell technology evaluation.

Requirements

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.

Nice to have

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.
