Senior Mechanical Engineer - Actuation Systems (Remote)

HireHawk Inc.; United States; Remote; USD 15,000 - 17,000; Full time

Job summary

HireHawk is seeking a Mechanical Engineer (Actuation) to lead design and development of high‑performance actuators and precision drive systems for advanced robotic platforms.

You will own architecture, CAD, prototyping, validation, and production readiness while collaborating with materials and customer engineering teams to ensure seamless integration across mechanical, electrical, and control systems.

Qualifications

• Bachelor's degree required in Mechanical Engineering, Robotics, Mechatronics, or a closely related engineering discipline.
• 3+ years designing electromechanical actuators, gear systems, precision drive mechanisms, or related mechanical systems.
• Strong understanding of mechanical design fundamentals: kinematics, statics, dynamics, and materials behavior.
• Proficiency with modern 3D CAD tools and mechanical simulation/analysis tools.
• Hands-on experience building, machining, assembling, and testing prototypes.
• Ability to extend mechanical design beyond CAD through physical validation and iterative design.

Responsibilities

• Design compact, high-performance rotary and linear actuators using harmonic or strain-wave, planetary, cycloidal, and novel drive architectures.
• Own actuator and precision-drive designs from concept through prototype, validation, production readiness, and customer integration.
• Apply first-principles engineering, kinematics, statics, dynamics, and materials knowledge to guide architecture and design decisions.
• Evaluate competing concepts via calculations, trades, simulation, and physical testing.
• Build and refine prototypes to improve torque density, efficiency, durability, and manufacturability.
• Collaborate with materials and manufacturing engineers to incorporate advanced materials and fabrication processes.
• Coordinate with customer engineering teams to ensure designs meet mechanical, electrical, packaging, and control-interface requirements.
• Produce CAD models, drawings, BOMs, and assembly documentation for manufacture and integration.
• Develop and execute verification tests, interpret data, identify root causes, and iterate designs.
• Participate in technical design reviews and support verification/integration activities.
