Principal Mechanical Engineer - Mechatronics

Our client is seeking a Senior Mechatronics Engineer to lead the design, development, and delivery of innovative electro-mechanical robotic systems. Youll own the mechanical subsystem design across a multidisciplinary team, contributing to hardware that will be deployed and scaled across real-world environments.

This is a hands-on, high-autonomy role in a fast-paced startup environment. The ideal candidate thrives in ambiguity, can pivot quickly, and brings a product-first mindset to engineering challenges.

• Lead mechanical and mechatronic system design from concept to production for robotic tire-changing platforms.

• Design and specify multi-axis actuators, gear drives, motors, sensors, and related components.

• Develop pneumatic and hydraulic circuit designs, including actuation systems, solenoids, and regulators.

• Perform finite element analysis (FEA) for structural, fatigue, and dynamic loads.

• Build and maintain CAD models and engineering documentation (GD&T, BOMs, test procedures).

• Create test plans and validate subsystems with structured data collection and analysis.

• Collaborate closely with cross-functional teams (software, controls, electrical) to integrate full-system functionality.

• Contribute to engineering processes such as lifecycle management, design reviews, and change control.

• Support installation, troubleshooting, and field deployments as needed.

• BS in Mechanical Engineering, Robotics, or a related field.

• 10+ years of professional experience in robotics, automation, or electro-mechanical system development.

• Proven track record in designing and delivering industrial robotic systems at scale.

• Deep experience with actuators, motors, gearing, sensors, and real-world integration.

• Proficient in 3D CAD (preferably OnShape or SolidWorks), with strong GD&T skills (ASME Y14.5).

• Skilled in FEA tools for static, dynamic, and fatigue analysis.

• Hands-on experience with pneumatics and hydraulics in robotic or automation applications.

• Strong documentation and communication skills; able to write clear procedures, test plans, and engineering reports.

• MS or PhD in Mechanical Engineering.

• Expertise in system dynamics, vibration analysis, or industrial tooling design.

• Experience with industrial control systems.

• Background in simulation tools, free body diagrams, and electro-mechanical equations.

• Familiarity with engineering documentation systems (CAD vaults, BOMs, part numbering).

• Python or MATLAB proficiency for test automation or data analysis.

• Competitive compensation and equity package.

• Medical, dental, and vision coverage.

• PTO and flexible time-off policies.

• A dynamic, collaborative team solving complex problems in robotics.

• A high-ownership culture with significant autonomy and room for technical leadership.
