Principal Mechanical Engineer

Responsibilities

• Serve as mechanical system architect for major product platforms
• Lead system-level design decisions, trade studies, and risk mitigation
• Establish mechanical standards, best practices, and reusable design architectures
• Drive cross-functional alignment across mechanical, electrical, software, and physics teams
• Lead development of complex electromechanical systems including structures, mechanisms, and enclosures
• Drive early-stage innovation by assembling and testing proof-of-concept prototypes to validate concepts and reduce technical risk
• Own mechanical execution across the full product lifecycle from concept through sustaining
• Resolve high-impact, cross-subsystem technical challenges
• Oversee tolerance analysis, structural integrity, environmental robustness, and reliability
• Partner with Operations to ensure manufacturable, scalable, and cost-effective designs
• Lead mechanical NPI efforts, production readiness, and supplier engagement
• Incorporate production, quality, and field feedback into continuous improvement
• Mentor engineers and lead technical design reviews
• Influence engineering roadmaps, resourcing, and long-term technical strategy
• Inspire engineering rigor, documentation quality, and technical excellence
• Travel as needed (e.g., to suppliers, manufacturing partners, field deployments, or customer sites) to support development, integration, and issue resolution

Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering
• 10+ years of mechanical engineering experience in complex product development
• Proven technical lead or system owner on shipped products
• Experience designing electromechanical systems such as handheld devices, large-scale industrial or vehicle-mounted equipment, or precision mechanisms
• Strong knowledge of manufacturing processes including injection-molded plastics, structural metals, welded assemblies, and tolerance management
• Advanced proficiency with SolidWorks or Onshape; working knowledge of FEA and mechanical simulation
• Excellent communication and cross-functional collaboration skills
• Demonstrated ownership of designs from concept through full-rate production
• Experience with ruggedized, safety-critical, or harsh-environment products; collaboration with Physics or Imaging teams preferred
• Passion for mission-driven engineering and real-world impact
