Job Summary:

We are seeking a Lead Mechanical Engineer to drive the design, development, and integration of industry-leading cutting-edge autonomous robotic systems. This role will oversee mechanical design efforts across multiple projects, lead a team of engineers, and collaborate cross-functionally to deliver robust, scalable, and high-performance autonomous systems.

Key Responsibilities:

• Lead the mechanical design,development,and testingof robotic platforms including chassis, actuators, enclosures, and integration of sensors and electronics.
• Own the full product development lifecycle from concept tocommercialization, including prototyping,lab and fieldtesting, anddesigniteration.
• Lead design reviews,DFMEAs,documentation efforts,and change releases.
• Collaborate with electrical, software, and systems engineers to ensure mechanical and system-level integration.
• Apply DFM (Design for Manufacturing) and DFA (Design for Assembly) principles for efficient production.
• Interface with vendors and suppliers forcomponentsourcing,validation,prototyping, and manufacturing support.
• Ensurescompliance withindustry-standardsafety, reliability, andregulatoryprinciples.
• Performsdesignverification andvalidation,and mechanical analysis (thermal, stress, dynamics).
• Develop and execute test plans for mechanical systems including field validation.
• Mentor junior engineers andestablishbest practices in mechanical design and systems engineering.

Qualifications:

• Bachelor's degree in mechanical engineeringor related field from an accredited university.
  MS in Mechanical Engineering (preferred).
• 7+ years of mechanical design experience, preferably in robotics, automation, or complex mechatronic systems.
