Mechanical Engineer - Robotic Actuator Test Systems

United States Digital Space LLC; United States; Remote; USD 90,000 - 130,000; Full time

Job summary

United States Digital Space LLC is seeking a Mechanical Engineer to own the mechanical side of robotic actuator dynamometer test infrastructure. You will design test stands, fixtures, frames, and guarding, and work with electrical and software teams to deliver high‑uptime test cells.

You will translate requirements into robust mechanical systems, perform first‑principles analysis, and iterate from CAD through fabrication to commissioning in a hands‑on lab environment.

Qualifications

• Bachelor's or graduate degree in Mechanical Engineering, Robotics, Mechatronics, or related field.
• Experience designing mechanical systems for robotic actuator dynamometers, robotics, automation, or high‑performance hardware.
• Proficiency with CAD and drawing release workflows; NX, SolidWorks, Creo or equivalent.

Responsibilities

• Design dynamometer structures, robotic actuator fixtures, load‑motor mounts, couplings, shafts, bearings, adapters, and torque‑reaction hardware.
• Translate test requirements into robust mechanical systems for torque, speed, thermal, durability, backdrive, efficiency, and failure testing.
• Perform first‑principles analysis and simulation for stiffness, strength, fatigue, vibration, thermal growth, critical speed, and safety factors.
• Create precise alignment strategies to protect test articles, load machines, sensors, and couplings.
• Design modular fixturing that supports rapid changeover across actuator variants without compromising measurement quality.
• Work with electrical and software engineers to define mechanical limits, safe operating envelopes, and automated‑test constraints.
• Build, assemble, debug, and improve test stands in the lab using measurement and fabrication tools.
