• Develop, review, and approve technical documentation, including:
  • System/Subsystem Design Descriptions (SSDD)
  • Software Requirements Specifications (SRS)
  • CAN Interface Control Documents (ICD)
  • Engineering development artifacts
• Provide technical leadership, mentorship, and guidance to engineering team members while supporting technology roadmaps and future capability development.
• Participate in internal reviews, customer demonstrations, and technical presentations.
• Work closely with cross-functional engineering teams to define interfaces, operational concepts, drive cycle profiles, performance requirements, and system integration strategies.
• Participate in peer reviews and support defect identification, root cause analysis, corrective actions, and issue resolution.
• Research and evaluate emerging technologies related to:
  • Hybrid electric vehicle systems
  • High-voltage battery technologies
  • Electric propulsion systems
  • Power electronics
  • Vehicle electrification architectures

Qualifications:

• U.S. Citizenship is required by Federal Law
