Your technical leadership will drive innovation in safety, mechanical integration, and cross-disciplinary collaboration for demanding real-world applications.

Responsibilities

• Architect, engineer, and optimize lightweight, swappable battery systems with emphasis on safety, weight reduction, and reliability for robotic applications.


• Lead design, validation, performance, endurance, and life cycle testing of battery subsystems, overseeing testing methodologies and data analysis.


• Diagnose and resolve mechanical issues through failure analysis, root-cause investigations, design iteration, and empirical validation.


• Guide contract manufacturers (CMs) and scaling partners in preparation for high-volume production transitions, ensuring manufacturability and quality.


• Work closely with reliability, electrical, and firmware engineers to implement best practices for high-reliability mechanical and electrical integration.


• Develop custom test fixtures, write test protocols, execute tests, and analyze measurement data to inform continuous design improvements.


• Design battery docking and interface components; support the development of ancillary robotic subsystems as needed.


• Oversee prototyping using diverse manufacturing processes and material choices suitable for battery and electronics enclosures.


• Execute tolerance analysis, GD&T application, and perform static structural and modal FEA simulations to validate mechanical robustness.

Minimum Qualifications

• 8+ years of mechanical design engineering experience, focused on complex electromechanical systems.


• Bachelor’s degree (or equivalent practical experience) in Mechanical Engineering or a related technical field.


• Demonstrated expertise developing lightweight, custom battery modules and mechanical packaging for electrical systems.


• Strong background in battery and electronics thermal management strategies.


• Hands-on with design-of-experiments (DOE) and execution of performance and validation test protocols.


• Proficient in advanced CAD tools such as SOLIDWORKS, Siemens NX, or similar platforms, and capable with manufacturing prototyping.


• Expertise in tolerance analysis and application of GD&T per industry standards.


• Skilled in finite element analysis (FEA) including both static structural and modal evaluations.


• Proven track record managing engineering projects under fast-paced, ambiguous, or evolving priorities.

Preferred Qualifications

• Experience developing robotics and/or consumer electronics products in high-performance, cross-functional teams.
