About the Role

The Director, Electrical Systems Engineering oversees a team responsible for battery systems electrical design, power electronics integration, safety, validation, and cross‑functional collaboration with software, electronics, testing, manufacturing engineering, projects and field services groups.

Responsibilities

• Lead the development and execution of electrical system design strategies, working cross functionally with embedded engineering, electronics, manufacturing engineering, projects and field teams

• Direct the development of mathematical / simulation models for power converters, switching devices, protection circuits, and system‑level energy flows

• Conduct electrical simulations (PSCAD, PSSE, PLECS, MATLAB/Simulink etc.) to validate system behavior, transient response, and fault‑handling performance.

• Establish modelling standards, simulation methodologies, and verification frameworks to ensure accuracy, repeatability, and traceability across engineering teams and across projects.

• Support hardware-in-the-loop system testing (custom, RTDS, Typhoon etc.) of battery electrical systems

• Work closely with the Electronics team to define requirements and designs for system electrical power and communication components. 

• Define requirements for surge, ESD, transient immunity, and protection coordination across the entire electrical system.

• Own the electrical system design roadmap for current and future battery systems

• Guide concept development, requirements definition, DFMEA, and design reviews.

• Oversee prototype builds, validation testing, and design-for-manufacturability.

• Build and mentor a high‑performance team of electrical system and modeling engineers with deep technical specialization.

Knowledge, Skill, and Abilities

• Advanced knowledge of high voltage DC systems, power conversion topologies, and grid‑connected inverter behavior

• Advanced knowledge of BMS architecture and algorithms, including SOC/SOH estimation, cell balancing, fault detection, and prognostics

• Advanced knowledge of power systems modeling and simulation, with deep expertise in SPICE, PLECS, MATLAB/Simulink, and multi‑domain co‑simulation

• Proven track record of delivering complex electrical systems from concept through production.

• Strong understanding of protection strategies, transient behavior, and fault‑tolerant design.

• Exceptional communication, leadership, and cross‑functional collaboration skills.

Education and Experience

• Bachelor’s degree in electrical or electronics engineering required

• Master’s degree in electrical or electronics engineering preferred

• 10+ years of experience in electrical or power electronics engineering, with at least 8 years in a leadership role.

Travel

• Local Travel: 10-25%

• Overnight/North America: 10-25%

• Other International Travel

Working Conditions

• Office Environment - Must be able to remain in a stationary position 50% of the time and occasionally move about inside the office to access file cabinets, office machinery, etc.  Required to have close visual acuity to perform an activity such as: preparing and analyzing data and figures; transcribing; viewing a computer terminal; extensive reading. May be required to exert up to 25 pounds of force occasionally to lift, carry, push, pull or otherwise move objects, including the human body.

• Factory - The worker may be subject to hazards. Incl
