Mechanical Engineer, Battery and Charger

Since its founding in 2015, 1X has been at the forefront of developing advanced humanoid robots designed for household use. Our mission is to create an abundant supply of labor via safe, intelligent humanoids. 

We strive for excellence in all we do, solving some of the hardest problems in robotics with the world’s most talented individuals. Every part of our robots is designed and produced in-house—from motor coils to AI—reflecting our vertically integrated approach. At 1X, you’ll own real projects, be recognized for your achievements, and rewarded based on merit.

We believe the best work is done when collaborating and therefore require in-person presence in our office locations. 

As we scale from research and development to full-scale manufacturing, we are seeking a Mechanical Engineer to take work on the battery and charging systems for NEO. In this role, you will design and optimize battery enclosures, thermal management systems, and charging docks to ensure safety, reliability, and scalability. 

RESPONSIBILITIES

• Design and develop mechanical enclosures for battery packs and charging systems, ensuring protection, reliability, and efficient assembly.

• Implement thermal management solutions to maintain battery performance and safety under various operating conditions.

• Design charging docks and connectors with a focus on ergonomics, durability, and seamless user experience.

• Collaborate with electrical engineering teams to ensure mechanical designs meet electrical and safety requirements, including IP ratings and vibration resistance.

• Conduct design validation tests (DVT) to ensure battery enclosures and chargers meet performance and durability specifications.

• Perform finite element analysis (FEA) for structural integrity and thermal performance of battery housings and connectors.

• Optimize designs for manufacturability (DFM) and assembly (DFA) to ensure cost-effective, scalable production.

• Work with manufacturing partners to develop tooling and production processes for battery enclosures and charging systems.

• Ensure compliance with regulatory standards and certifications (e.g., UN 38.3, UL, IEC).

• Create and maintain detailed documentation, including CAD models, drawings, test plans, and assembly instructions.
