Apptronik is a human-centered robotics company developing AI-powered robots to support humanity in every facet of life. Our flagship humanoid robot, Apollo, is built to collaborate thoughtfully with people, starting with critical industries such as manufacturing and logistics, with future applications in healthcare, the home, and beyond.
We operate at the cutting edge of Applied AI, applying our expertise across the full robotics stack to solve some of society's most important problems. You will join a team dedicated to bringing Apollo to market at scale, tackling the complex challenges like safety, commercialization, and mass production to change the world for the better.
JOB SUMMARY
We are seeking a Staff Mechanical Engineer – Robotic Hand Design Tech Lead to lead the structural design and architecture of a next-generation robotic hand for a humanoid platform. This role goes beyond traditional end effectors—focusing on highly dexterous, human-like manipulation in unstructured environments.
As the technical lead for hand structures, you will define and drive the mechanical design of complex, multi-DOF systems that must balance strength, compliance, weight, and tactile interaction. You will work at the intersection of biomechanics, precision engineering, and robotics to create a hand capable of robust, versatile, and safe interaction with the world.
ESSENTIAL DUTIES AND RESPONSIBILITIES or KEY ACCOUNTABILITIES
- Own the robotic hand structural architecture
Define the mechanical architecture of a multi-fingered humanoid hand, including finger topology, joints, palm structure, and load paths, balancing dexterity, strength, and weight.
- Lead design of fingers and joints
Develop robust, multi-DOF mechanisms with appropriate joint types, ensuring durability under off-axis loads, impacts, and real-world use.
- Co-design with actuation systems
Partner with actuation team on tendon-driven or remote actuation designs, including cable routing, transmission efficiency, and wear reduction.
- Engineer for contact-rich, human-like interaction
Design for grasping, pinching, sliding, and tool use, balancing compliance and stiffness for both precision and safe interaction.
- Drive structural analysis and durability
Own FEA and validation for stress, fatigue, and impact. Design for high cycle life and address failure modes like wear, loosening, and material fatigue.
- Enable compact, integrated designs
Build high-density mechanical systems that integrate actuation, sensing, and wiring within tight space constraints.
- Lead prototyping and iteration
Rapidly prototype, test, and refine designs based on hands-on evaluation and system-level feedback.
- Own manufacturability and scale-up
Drive DFM/DFA, process selection, tolerancing, and supplier collaboration to ensure production-ready designs.
- Collaborate cross-functionally
Work closely with controls, perception, electrical, and software teams to deliver a cohesive manipulation system.
- Provide technical leadership
Mentor engineers, lead design reviews, and set best practices for dexterous manipulation systems.
SKILLS AND REQUIREMENTS
- Drive Through Influence: A proven ability to lead technical initiatives and align cross-functional stakeholders without direct reporting authority. You must be able to build consensus on complex architectural trade-offs.
- Surfacing Expertise: Proven ability to work with Class-A surfaces and complex geometries; expert-level proficiency in surfacing tools within SolidWorks, NX, Catia…
- Subject Matter Expertise: Proven track record of designing multi-axis robotic arms or high-DOF dynamic mechanisms.
- Packaging Mastery: Exceptional skills in "tight-space" integration; experience with ruggedized electronics packaging or automotive/aerospace interiors is a plus.
- Education: BS/MS in Mechanical Engineering, Robotics, or a related field.
- Direct experience with robotic hands, dexterous manipulation, or anthropomorphic mechanisms is preferred
- Familiarity with human hand biomechanics or bio-inspired design principle sis preferred
- Experience with tendon-driven systems, cable routing, or underactuated mechanisms is preferred
- Background in compliant or soft robotic structures is preferred
- Experience integrating tactile sensing or force feedback into mechanical designs is preferred
- Knowledge of advanced materials and surface treatments for wear and grip optimization is preferred
EDUCATION and/or EXPERIENCE
- Education: B.S in Mechanical Engineering
- Experience: 8 years of experience in mechanical design of complex robotic systems
PHYSICAL REQUIREMENTS
- 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
- Hearing and speech to communicate
