Technical Lead, Mechanical Engineering

As we scale from research and development to full-scale manufacturing, we are looking for a Technical System Lead in Mechanical Engineering to architect and deliver the mechanical systems that define the performance of our humanoid robot’s joints and body structures. This is a hands-on leadership role that requires both exceptional engineering ability and the vision to guide teams through complex trade-offs and integration challenges. In this role, you will blend personal technical execution with system-level ownership and the development of a high-performing mechanical engineering team.

Responsibilities:

• Architect, design, and validate the mechanical systems comprising the robot’s joints, actuators, structural elements, and associated interfaces.
• Lead and personally contribute to detailed mechanical design, including 3D CAD development, tolerance analysis, materials selection, and structural optimization.
• Drive system-level trade studies and make key decisions balancing strength, weight, manufacturability, thermal performance, and cost.
• Guide the integration of mechanical systems with actuators, sensors, electronics, and thermal management components.
• Oversee prototyping and validation, including test plan development, execution, and design iteration based on results.
• Establish engineering processes, design standards, and documentation to enable repeatable, high-quality product development.
• Mentor, develop, and inspire a team of mechanical engineers working on critical subassemblies.
• Collaborate closely with manufacturing, electrical, and controls engineering teams to deliver robust and scalable solutions.
• Model hands-on technical excellence and foster a culture of accountability, curiosity, and continuous improvement.

Must-Haves:

• First principles thinker, creative, push the boundaries of engineering.
• Understands how to develop real products that consumers will love and not just engineering solutions.
• Deep hands-on experience creating complex mechanical systems, preferably in robotics, mechatronics, or precision assemblies.
• Proven track record as a technical lead driving products from concept to production.
• Deep expertise in actuator packaging, high-load joints, structural design, and system integration.
• Strong proficiency in 3D CAD, simulation tools (FEA, motion analysis).
• Demonstrated experience with rapid prototyping, test development, and failure analysis.
• Familiarity with manufacturing processes relevant to robotics (machining, casting, additive, composites).
• Excellent communication and collaboration skills to lead multidisciplinary efforts.
• Hands-on, pragmatic approach, comfortable moving between detailed design work and high-level architecture decisions.

Location Policy

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

We're excited to get to know you and the prospects of having you on board!
