Lead Engineer - High Voltage Battery Systems

Apply now
FutureMotiv is delivering electrification programmes across commercial vehicles, marine, off-highway machinery, specialist vehicles and emerging zero-emission technologies. We are looking for an experienced battery systems engineer who can take ownership of technical delivery from concept definition through to prototype manufacture, testing and vehicle integration.

This is a hands-on engineering role for someone who enjoys solving real-world problems rather than managing from a distance. You will work directly with customers, suppliers and multidisciplinary engineering teams to develop high-voltage battery systems for challenging low-volume, prototype and production-intent applications.

Key Responsibilities

  • Lead the development of high-voltage lithium-ion battery systems from requirements capture through design release, integration, validation and production readiness.
  • Define battery system architectures including cell selection, module design, pack design, electrical distribution, protection strategies and thermal management concepts.
  • Support prototype build activities, battery assembly, commissioning, fault finding and engineering rework.
  • Generate and manage system requirements, technical specifications, DFMEA activities and design verification plans.
  • Work closely with simulation engineers to define and review structural, thermal, electrical and safety analyses, ensuring results are translated into robust engineering solutions.
  • Specify and manage battery subsystem suppliers, including cells, BMS, cooling systems, enclosures, HV components and electrical interfaces.
  • Lead technical discussions with customers, suppliers and project stakeholders.
  • Develop test strategies and oversee component, subsystem and vehicle-level validation activities.
  • Design and commission test rigs, analyse test data and drive issue resolution through structured root cause analysis.
  • Ensure compliance with functional safety, high-voltage safety and relevant automotive standards and regulations.
  • Support engineering reviews, design releases and engineering change management activities throughout the programme lifecycle.
  • Mentor and support junior engineers across battery, electrical and systems engineering disciplines.

What We're Looking For

  • Degree qualified in Electrical, Electronic, Automotive, Mechanical Engineering or a related discipline.
  • Typically 8+ years' experience delivering high-voltage battery or electrified powertrain systems.
  • Proven experience developing lithium-ion battery systems within an OEM, Tier 1 supplier, motorsport, specialist vehicle or advanced engineering environment.
  • Strong understanding of battery pack architecture, electrical distribution systems and battery integration.
  • Experience of battery management systems (BMS), including SOC, SOH, balancing strategies, diagnostics and fault management.
  • Good understanding of battery thermal management, cooling system design and thermal performance considerations.
  • Familiarity with HV safety concepts including HVIL, insulation monitoring, manual service disconnects, contactor control and fault protection strategies.
  • Practical experience of battery testing, development builds, fault investigation and validation activities.
  • Working knowledge of automotive development processes including requirements management, DVP&R, FMEA, engineering change management and release processes.
  • Experience supporting compliance to standards such as ISO 26262, UN ECE R100 and UN 38.3.
  • Comfortable working directly with customers and suppliers in a technically demanding environment.

Personal Qualities

  • Strong engineering ownership and accountability.
  • Hands-on approach with a willingness to get involved in prototype build and test activities.
  • Pragmatic problem solver who can balance engineering rigour with programme delivery.
  • Self-motivated and capable of operating with minimal supervision.
  • Excellent communication skills and confidence engaging with customers at both technical and programme level.
  • Adaptable and comfortable working across multiple projects and technologies.
  • Able to operate effectively within a fast-moving consultancy and customer-facing environment.
