Ideal Background

• 2+ years of experience in mechanical engineering, preferably in robotics, automotive, or hardware startups
• Strong CAD experience designing both prototype and production-ready components
• Experience owning hardware systems through full development cycles
• Familiarity with manufacturing processes (machining, injection molding, fabrication, etc.)
• Experience evaluating supplier designs, test plans, and technical requirements
• Ability to collaborate effectively with external vendors and internal cross-functional teams
• Bachelor’s degree in Mechanical Engineering, Mechatronics, or related field
• Comfortable operating in fast-paced, ambiguous startup environments
• Willingness and eligibility to obtain a U.S. security clearance
• Ability to relocate to Phoenix, AZ

---

Preferred

• Master’s degree in Mechanical Engineering or Mechatronics
• Experience designing ruggedized systems for off-road or defense applications
• Background working on autonomous vehicles, robotics platforms, or similar hardware systems
• Experience meeting or designing toward DoD or other high-reliability standards

---

Compensation and Benefits

• Competitive base salary + equity
• Opportunity to work on cutting-edge autonomous systems with real-world impact
• High ownership role with end-to-end hardware responsibility
• Fast-paced, mission-driven environment with direct influence on product direction
• Exposure to complex, multidisciplinary engineering challenges across robotics, autonomy, and hardware systems
