We are looking for a Mechanical Engineer to join a small, highly skilled team building advanced humanoid robotic platforms capable of dynamic, real-world operation. You will design and integrate complex mechanical subsystems - including actuation, structural frames, transmission systems, and thermal solutions. The ideal candidate thrives in fast-paced hardware development environments and has demonstrated success delivering high-performance electromechanical systems from prototype to scalable production.
Main Responsibilities
* Design and develop mechanical components and subsystems for humanoid robots, including structural frames, precision joints, and actuator assemblies, using advanced CAD tools and rigorous GD&T practices.
* Engineer high-performance robotic linkages and transmission mechanisms optimized for dynamic motion, load handling, durability, and energy efficiency.
* Select materials and manufacturing processes that balance strength, weight, cost, and scalability to ensure both prototype feasibility and production readiness.
* Collaborate with in-house manufacturing team for rapid prototyping efforts using additive manufacturing, CNC machining, and iterative hardware testing to validate and refine designs.
* Collaborate closely with electrical and software engineering teams to integrate mechanical systems with sensing, control, and embedded hardware architectures.
* Conduct mechanical analysis and validation testing (e.g., FEA, fatigue, impact, and life-cycle testing) to verify performance under real-world operating conditions.
* Drive safety-by-design principles, performing risk assessments and implementing safeguards to meet applicable regulatory and operational safety standards.
* Generate and maintain detailed engineering documentation, including production drawings, tolerance analyses, specifications, and bills of materials.
* Contribute to system-level design reviews and cross-functional execution to ensure on-time, high-quality hardware delivery.
* Balancing Performance vs. Constraints: Managing trade-offs between strength, low weight, energy efficiency, reliability, and thermal management in a compact form factor, including designing custom high-precision actuation systems.
* Cross-Functional Integration and Interfacing: Ensuring seamless, rigorous integration of complex mechanical, electrical, and software subsystems, optimizing for cabling, sensors, and motor control.
* Scalability and Production Transition: Moving designs rapidly from custom prototypes to a robust, cost-effective, and scalable manufacturing process to support volume production growth.
* Fast-Paced, Multi-Disciplinary Environment: Thriving in a lean, fast-moving company, requiring the ability to own projects end-to-end, rapidly iterate, and adapt to evolving processes and tight deadlines.
* Adherence to Safety and Regulatory Standards: Implementing robust risk assessments and built-in safeguards from the initial design phase to ensure dynamic robotic systems meet international safety standards.
Qualifications, Knowledge, Key Skills and Experience
* Strong background in mechanical design, statics, dynamics, and material science.
* Advanced proficiency in 3D parametric CAD (preferably Autodesk Inventor).
* Deep understanding of GD&T and tolerance stack-up analysis.
* Strong background in mechanism design, linkages, bearings, power transmission, and actuator integration.
* Experience performing FEA and structural validation for dynamic loading conditions.
* Hands‑on prototyping experience.
* Knowledge of material selection for lightweight, high‑strength structures (aluminum alloys, steels, composites).
* Experience designing for manufacturability (DFM) and assembly (DFA).
* Ability to work cross‑functionally with electrical and controls teams to integrate motors, sensors, wiring, and embedded systems.
* Proven ability to take hardware from concept through validation and into production.
* Direct experience developing legged or humanoid robotic systems.
* Experience designing custom actuators, gear trains (harmonic drives, cycloidal reducers, planetary systems), or high‑precision joints.
* Knowledge of thermal management for compact electromechanical assemblies.
* Familiarity with motion control systems and basic control theory.
* Understanding of safety standards for robotic systems.
* Startup experience or experience in fast‑paced hardware development environments.
* Experience transitioning from prototype to volume manufacturing.
* Experience with mesh organic mesh modelling (Blender, Z‑Brush).
