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.

  • StrongproficiencyinSolidWorksandSolidworksPDM,3D CADmodeling,and mechanical simulation tools(Ansys, FEA, CFD, tolerance stack analysis).

  • Understand and apply GD&T standards.

  • Solid grasp of EMI/EMC concepts including system level grounding and shielding.

  • Designing forharsh environments (temperature, shock, vibration).

  • Knowledge of CSA Class1, Div2 ,CE,anUL(preferred).

  • Demonstrabletrack recordofthe delivery of commercial products.

  • Hands-on experience with prototyping tools (e.g., 3D printing, CNC, sheet metal fabrication).

  • Deep understanding of materialselection, structural design, thermal management, and kinematics.

  • Experiencewithelectro-mechanicalcomponents such as actuators,stepperand drive motors,gearboxes, sensors, and embedded systems.
