What You Will Do
Lead mechanical design and integration efforts for autonomous ground vehicle systems
Design and develop ruggedized hardware solutions for sensors, compute systems, and custom components
Own hardware development from concept through prototyping, testing, and production
Collaborate with suppliers and OEM partners to evaluate designs, requirements, and manufacturability
Integrate mechanical systems across vehicle platforms to support autonomy and durability in harsh environments
Drive full product lifecycle execution, including design validation, iteration, and deployment
Work cross-functionally with electrical, embedded, and autonomy teams to ensure system-level performance
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
This role is ideal for a hands-on mechanical engineer who wants full ownership over hardware systems and thrives building rugged, real-world robotics products from the ground up.
