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. Excellent communication, leadership, and cross-functional collaboration skills.

Experience working within ISO 9001:2015 Quality Management System Framework and other regulated frameworks. Experience in commercial product/system delivery in harsh environments. Experience with ERP systems (i.e.SAP, NetSuite),andQMS systems (i.e.Arena, Adept,MasterControl). Experience leading engineering projects and teams.

Preferred Experience: Autonomous or semi-autonomous mobile robots (e.g., drones, AMRs, humanoids). Design for rugged environments (military, industrial, outdoor). Familiarity with robotics standards (ISO 10218, R15.06, etc.) Experience with agile development and rapid prototyping environments is a plus Working knowledge of motion control, embedded systems, and system integration.

Experience in a manufacturingenvironment. Experience ensuring product quality including standards, statistical methods,and testing.
