Electrical Integration Engineer

You’ll be working with the Research and Development team This team runs on coffee with an infectious passion to build products that have never been built before. Our Flexible Energy Stack consists of the e^pack (battery pack), e^Port (charging connector), e^Plug (charging connector) and e^pump (charging station) which together unlock 15-minute rapid charging.

Exponent’s philosophy: Break. Believe. Build. There’s no playbook for disruption. The only way to create a radical future is to continuously break, believe and build. Break assumptions and thumb rules. Believe in the process, the team, and through failures. Build fast, passionately, and with first-principles thinking.

Job Description We are seeking a hands-on Electrical Integration Engineer to lead the design, integration, and validation of high-voltage electrical systems across Exponent’s EV energy products. This role sits at the intersection of electrical design, power electronics, firmware integration, and electro-mechanical systems, with ownership from concept to production. The ideal candidate will drive end-to-end electrical architecture, ensure safety and compliance of HV systems, and debug complex hardware–software interactions in fast-evolving EV platforms.

Key Responsibilities Electrical Design & Safety

• Design and coordinate multi-stage electrical protection schemes for HV and LV systems

• Size and select protection devices, switchgears, and cables

• Own insulation coordination, including creepage and clearance definitions

• Design earthing and grounding architectures for HV systems

• Ensure compliance with IS, IEC, ISO, SAE, CSA, NFPA, CEA, NEC, NBC standards

• Own HVDC safety concepts and validation

Electrical & System Integration

• Integrate power electronics hardware including converters, inverters, sensors, and actuators

• Review and debug schematics, PCBA designs, and component ratings

• Lead hardware–firmware integration, including protocol-level debugging

• Support EMI/EMC testing, harness design, and routing considerations

• Analyze and mitigate effects of parasitics in automotive systems

Firmware & Debugging

• Debug communication protocols: CAN, UART, MODBUS, SPI
• Work with MCU peripherals including ADC configuration
• Diagnose and resolve hardware–software interaction issues
• Collaborate with firmware teams during bring-up and validation

Electro-Mechanical Systems

• Perform thermal and fluid flow calculations for electrical systems
• Define packaging, separation, filters, and ingress protection strategies
• Interface with chillers and HVAC systems for thermal management

Reliability & Engineering Excellence

• Own DFMEA and drive mitigation actions
• Lead root cause analysis (RCA) for electro-mechanical failures
• Support reliability testing and modelling across product lifecycle

Required Skills & Experience

• Experience across 2+ full product development cycles in one or more of the following:

• Electrical protection & insulation coordination design

• EV powertrain or >500V battery architecture

• Power electronics converter design or application

• Strong fundamentals in electrical circuit analysis

• Hands-on experience debugging CAN, MODBUS, SPI

• Proven experience driving DFMEA and reliability validation

• Bachelor’s or Master’s in Electrical / Electronics / Mechatronics Engineering

Preferred Qualities

• First-principles thinker with strong debugging instincts
• Comfortable working across electrical, firmware, and mechanical teams
• Bias for ownership in a fast-paced startup environment
• Passion for EVs, clean energy, and building hardware that scales

What Matters at Exponent

• Quality of work and attention to detail
• Structured problem-solving approach
• Discomfort with mediocre solutions
• Resilience and learning mindset through failures
