Senior Mechanical Design Engineer

What You’ll Do:

The Senior Mechanical Design Engineer will design and develop mechanisms and moving assemblies for Space Kinetic’s core technology, supporting our goal of a flight demonstration within the next two years. This role will guide prototype builds and work across simulation, electrical, manufacturing, and systems engineering.

Job Responsibilities:

• Design space-rated mechanisms, including release systems, actuators, gear trains, linkages, payload-pointing systems, and precision motion assemblies.
• Perform kinematic studies, torque and friction calculations, tolerance analysis, and material and component selection.
• Create 3D CAD models, assemblies, drawings, and simplified models for simulation and FEA.
• Design, build, and test prototypes to validate functionality and performance.
• Investigate test anomalies and implement corrective design changes.
• Support TVAC, vibration, shock, deployment testing, and spacecraft assembly and integration.
• Apply DFM and DFA principles to improve producibility, cost, and schedule.
• Maintain design documentation and present at SRR, PDR, CDR, and TRR reviews.

What It Takes:

• Bachelor’s or master’s degree in Mechanical Engineering or a related field.
• 5+ years of mechanical design experience focused on mechanisms.
• Strong knowledge of kinematics, dynamics, gears, cams, linkages, springs, bearings, and power transmission.
• Proficiency with SolidWorks, Creo, CATIA, NX, or similar 3D CAD software.
• Experience with GD&T, tolerance stack-up analysis, prototype development, and testing.
• Ability to work independently, solve problems, and collaborate across engineering teams.
• Ability to obtain and maintain a U.S. government security clearance.

What We’d Love:

• Experience designing deployable space mechanisms or high-reliability aerospace hardware.
• Knowledge of space-rated materials, lubricants, bearings, and coatings.
• Experience with spacecraft structures and payload integration.
• Familiarity with NASA or DoD spacecraft development standards.
• Hands-on experience building prototypes and troubleshooting mechanisms.
• Experience working in fast-paced spaceflight development programs.

Where You’ll Be:

The position is onsite at our headquarters in El Segundo CA . Domestic travel may be required (up to ~20% of the year).

What We Offer:

• Equity-Based Compensation
• 401(k) retirement plan with a 3.5% company match
• Highly Competitive PTO
• Paid company holidays + winter break
• Comprehensive medical, dental, and vision insurance
• Unique Performance-based bonus opportunities
