About the Job

Requirements

  • A bachelor's degree in electrical engineering or a related engineering discipline, or equivalent practical experience.
  • Significant experience in electrical engineering, including leading the design and development of complex electrical systems for physical products.
  • Demonstrated experience leading and developing engineers through direct people management, mentorship, and technical leadership.
  • Deep understanding of electrical system architecture, circuit design, power distribution, electrical interfaces, and hardware integration.
  • Experience taking electrical designs from concept through prototyping, testing, validation, and production.
  • Ability to evaluate technical tradeoffs across performance, reliability, safety, cost, packaging, and manufacturability.
  • Experience working closely with embedded firmware and control systems, including ECU design and hardware-software integration.
  • Strong problem-solving skills and the ability to lead technical investigations from initial symptoms through root cause and resolution.
  • A hands-on approach and the technical depth to engage directly in design reviews, troubleshooting, and complex engineering decisions.
  • Clear communication skills and the ability to work effectively across engineering disciplines, manufacturing, and company leadership.
  • Comfort operating in a growing company where priorities evolve, processes are still being built, and leaders are expected to take ownership beyond their immediate area.

Responsibilities

  • Own the electrical engineering function, setting technical direction, priorities, and engineering standards across the company's products and programs.
  • Lead electrical system architecture and design, balancing performance, safety, reliability, packaging, weight, cost, and manufacturability.
  • Guide electrical design across complex electromechanical systems, including power distribution, control systems, ECUs, and supporting electronics.
  • Make and communicate sound technical decisions, working through tradeoffs and resolving complex design challenges.
  • Establish design review, documentation, verification, and validation practices that support quality and consistency as the team scales.
  • Lead electrical design from early architecture and requirements through detailed design, prototyping, integration, testing, and production.
  • Partner with mechanical engineering, embedded firmware, systems integration, and manufacturing to ensure electrical systems work seamlessly across the product.
  • Oversee the design and integration of electrical interfaces, control electronics, wiring, connectors, and related systems.
  • Work through system-level issues, lead root cause analysis, and drive problems to resolution.
  • Ensure designs account for applicable electrical safety requirements, environmental conditions, electromagnetic compatibility, and production constraints.
  • Collaborate with manufacturing to develop practical, repeatable approaches to assembly, testing, and quality control.
  • Manage, mentor, and develop electrical engineers, including providing technical guidance, setting clear expectations, and supporting individual growth.
  • Establish clear ownership, priorities, and accountability across electrical engineering projects.
  • Build a collaborative team culture where engineers take initiative, challenge assumptions, and solve problems together.
  • Identify capability gaps and help shape the hiring plan as the company expands its electrical engineering organization.
  • Develop engineering processes and standards that improve execution without adding unnecessary bureaucracy.
  • Partner with engineering and company leadership to align electrical engineering priorities with customer requirements and business objectives.
  • Work directly with cross-functional teams and customers to understand technical requirements, communicate tradeoffs, and resolve issues.
  • Balance competing program needs while maintaining technical quality and execution.
  • Help build the engineering organization, tools, and processes needed to support the company's next stage of growth.

Desired Qualifications

  • Experience in automotive, motorsports, powersports, aerospace, robotics, or other complex electromechanical products.
  • Experience with ECU architecture and design, embedded control electronics, and hardware-software integration.
  • Experience with high-voltage and low-voltage electrical systems, including power distribution and electrical safety.
  • Experience with electrified powertrains, energy systems, or other electrically driven products.
  • Experience with design for manufacturing, automated production, and electrical end-of-line testing.
  • Experience building or scaling an engineering team in an early-stage or high-growth environment.
