Senior Mechanical Engineer (Battery and Docking Station)

The role

You will lead the mechanical design and development of the battery system and autonomous docking infrastructure for the Apollo humanoid robot. This role involves developing robust, manufacturable, and serviceable solutions for charging and battery integration.

What you will do

• Lead mechanical design and integration of battery packs, enclosures, and mounting systems.
• Design autonomous docking stations, charging interfaces, and alignment mechanisms.
• Define mechanical architectures for battery retention, thermal interfaces, and sealing strategies.
• Collaborate with Electrical, Controls, Systems, Firmware, and Software teams.
• Perform structural, thermal, and tolerance analyses to validate designs.
• Build and evaluate prototypes through laboratory and field testing.
• Partner with Manufacturing, Supply Chain, and Quality teams to optimize designs for production.
• Work with suppliers to develop components and qualify production-ready hardware.
• Ensure battery and docking systems meet safety, environmental, and reliability requirements.
• Mentor junior engineers and establish mechanical design best practices.

Required qualifications

• Bachelor's or Master's degree in Mechanical Engineering or a related field.
• 6+ years of professional experience in mechanical design.
• Significant experience in battery design, packaging, charging systems, robotics, automotive, aerospace, consumer electronics, or other complex electromechanical products.
• Strong experience designing precision mechanical assemblies using CAD (NX, or similar).
• Proficiency in tolerance analysis and mechanical validation methods.
• Demonstrated success taking products from concept through prototype, validation, and production.
• Strong analytical and troubleshooting skills.
• Excellent cross-functional collaboration and technical communication skills.
• Prolonged periods of sitting at a desk and working on a computer.
• Must be able to lift 15 pounds at times.
• Vision to read printed materials and a computer screen.
