Staff Mechanical Engineer (Tech Lead)

Join Apptronik, a leading robotics company, as a Staff Mechanical Engineer (Tech Lead) for Apollo's lower body. In this high-visibility leadership role, you will own the complete lifecycle of the lower body stack, including architecture, design, integration, and verification. You will lead the development of systems that deliver human-like mobility, absorb high-energy impacts, and maintain durability across millions of cycles in real-world environments. This position requires deep expertise in locomotion kinematics, dynamic stability, and high-load structural design.

• Lead the design and development of the mechanical architecture for the lower body of the robotic system, including the hips, legs, knees, ankles, and feet.
• Oversee the complete lifecycle of the lower body stack, from architecture and design to integration and verification, ensuring compliance with performance and durability requirements.
• Collaborate with cross-functional teams to ensure that mechanical designs support force control, impedance control, and dynamic motion planning.
• Must be able to lift 15 pounds at times
• Prolonged periods of sitting at a desk and working on a computer
• Vision to read printed materials and a computer screen
• Hearing and speech to communicate
• Experience: B.S. in Mechanical Engineering with a 8+ years of experience in mechanical design of complex robotic systems, with a focus on legged systems or high-load dynamic mechanisms
• Locomotion & Dynamics: Deep understanding of kinematics, dynamics, and control considerations for legged locomotion
• Drive Through Influence: Proven ability to lead technical initiatives and align cross-functional stakeholders without direct authority. Strong track record of driving system-level decisions
• Structural & Fatigue Design: Expertise in designing for high-cycle fatigue, impact loading, and durability
• CAD Expertise: Expert-level proficiency in CAD tools (SolidWorks, NX, CATIA)
• Packaging Mastery: Strong experience integrating actuators, sensors, and structures in compact, high-performance systems
• Education: BS/MS in Mechanical Engineering, Robotics, or a related field
• Subject Matter Expertise: Demonstrated experience designing multi-axis robotic legs, exoskeletons, or comparable high-DOF dynamic systems
