Senior Electrical Engineer

IONETIC is a battery pack company in Brackley, a few miles from Silverstone. It builds tailored packs for low-volume electrified applications such as buses and sports cars. It is recruiting a Senior Electrical Engineer to lead development of the electrical systems behind those packs, covering HV and LV architecture, safety circuitry, sensing and integration with the battery management system. The role works closely with the mechanical, software and manufacturing teams to keep designs safe, scalable and suited to high-performance, low-volume production.

Key responsibilities

• Lead design and development of electrical architectures for battery modules and packs, including HV distribution, LV electronics, fusing, contactors, sensing and interconnects
• Select and specify electrical and electro-mechanical components against performance and safety requirements
• Define and maintain system-level and component-level electrical requirements
• Conduct and support electrical DFMEA activities
• Ensure designs comply with relevant automotive and battery safety standards, such as UN 38.3, IEC, UL and ISO 6469
• Create and run electrical design verification and validation plans
• Lead fault analysis and root-cause investigations
• Work with BMS engineers to integrate hardware, sensing strategies, protection circuitry and communication interfaces
• Align electrical and mechanical designs on assembly sequence, manufacturability and thermal considerations
• Support prototype builds, system bring-up, testing and customer integration

Requirements

• Bachelor’s degree or higher in electrical or electronic engineering, or a closely related discipline
• At least 5 years of experience in electrical design for battery systems, HV systems or automotive electrical engineering
• Strong understanding of battery architectures, HV safety, sensing design and protection strategies
• Experience with BMS hardware, communication interfaces and automotive electrical design practices
• Familiarity with systems engineering principles, including requirements management and the V-model
• Experience with DFMEA, DVP and structured product development processes
• Strong analytical, problem-solving and decision-making skills
• Ability to communicate clearly through reports, schematics and presentations
• Valid UK driving licence or suitable alternative travel arrangements
• Willingness to travel within the UK and internationally as required
