About the role

Senior Mechanical Engineer responsible for leading mechanical design and development of battery systems and autonomous docking infrastructure for Apollo humanoid robot, coordinating across mechanical, electrical, controls, manufacturing, and systems teams to deliver robust, manufacturable, and serviceable solutions for charging, battery integration, and long-term field performance.

Responsibilities

  • Battery System Design: Lead the mechanical design and integration of battery packs, enclosures, mounting systems, structural components, and service interfaces while meeting performance, safety, and manufacturability requirements.
  • Docking Station Development: Design autonomous docking stations, charging interfaces, alignment mechanisms, and structural assemblies that enable reliable robot charging and battery engagement under repeated use.
  • Mechanical Architecture: Define mechanical architectures for battery retention, thermal interfaces, sealing strategies, connector protection, and structural load paths throughout the battery and docking systems.
  • Cross-Functional Integration: Collaborate closely with Electrical, Controls, Systems, Firmware, and Software teams to ensure seamless integration between charging hardware, battery electronics, sensing, and robotic operation.
  • Analysis & Validation: Perform structural, thermal, and tolerance analyses to validate designs. Support prototype testing, root cause investigations, and design iterations using both simulation and physical testing.
  • Prototype Development: Build and evaluate prototypes through laboratory and field testing, identifying opportunities to improve durability, usability, and reliability.
  • DFM & Production Support: Partner with Manufacturing, Supply Chain, and Quality teams to optimize designs for production, assembly, cost, serviceability, and scalability.
  • Supplier Collaboration: Work directly with suppliers to develop components, review manufacturability, resolve technical issues, and qualify production-ready hardware.
  • Reliability & Safety: Ensure battery and docking systems meet safety, environmental, and reliability requirements through rigorous design reviews, testing, and validation.
  • Technical Leadership: Mentor junior engineers, establish mechanical design best practices, and drive engineering excellence across battery and charging hardware development.

Qualifications

  • Mechanical Design Expertise: Strong experience designing precision mechanical assemblies using CAD (NX, or similar), including sheet metal, machined parts, castings, plastics, and structural assemblies.
  • Battery Hardware Knowledge: Experience developing battery enclosures, structural battery components, charging interfaces, connector systems, or power electronics packaging is highly preferred.
  • Engineering Analysis: Proficiency in tolerance analysis, and mechanical validation methods, with an understanding of thermal and structural considerations for battery systems.
  • Manufacturing Experience: Demonstrated success taking products from concept through prototype, validation, and production while working closely with suppliers and manufacturing teams.
  • Problem Solving: Strong analytical and troubleshooting skills with the ability to balance performance, reliability, cost, manufacturability, and schedule.
  • Communication: Excellent cross-functional collaboration and technical communication skills.
  • Education: Bachelor’s or Master’s degree in Mechanical Engineering or a related field.
  • Experience: 6+ years of professional experience in mechanical design, with significant experience in battery design, packaging, charging systems, robotics, automotive, aerospace, consumer electronics, or other complex electromechanical products.
