A New Paradigm For Space Operations.
Who We Are:
Space Kinetic is a dual use space technology startup building a completely new architecture for space operations – one that brings the advantages of proliferated drone technology (low-cost, operationally flexible, attainable, distributed) to space missions while reducing the ecosystem’s reliance on consumable fuel. In a world where many companies are focused on incrementally improving the status quo, we are focused on creating something entirely different – an architecture underpinned by new first principles to meet the opportunities and challenges of the third space age head-on. Our goal is to move away from one-to-one space architectures – where each satellite in a constellation has one (or a small # of) primary payloads attached to the bus – and unlock a ‘one-to-many’ system, where each satellite has a large number of payloads which can be deployed from their host spacecraft at high velocities without firing a thruster.
This is not a role for someone looking for a traditional 40-hour work week. Space Kinetic is building ambitious, first-of-its-kind technology, and that requires urgency, ownership, and a high level of commitment to changing the foundational assumptions for everything we do in space.
What You’ll Do:
The Machine Design Engineer will design, build, and refine prototypes for Space Kinetic’s core technology as we work toward a flight demonstration within the next two years. You will collaborate with engineering, manufacturing, machinists, test teams, and external vendors to move hardware from early prototypes toward a flight-ready design. This role requires strong mechanical design fundamentals, hands-on problem-solving, and the ability to use test results to drive continuous design improvements.
Job Responsibilities:
•
Refine prototype CAD models, precision mechanisms, tolerance analyses, and detailed 2D manufacturing drawings.
•
Design and integrate rotary mechanisms, bearings, motors, gearboxes, springs, fasteners, and related mechanical components.
•
Collaborate with machinists, manufacturing teams, and vendors to source components and ensure designs are producible.
•
Redesign prototype hardware to achieve a targeted 30% weight reduction while improving stiffness, structural performance, and vibration response.
•
Apply GD&T and Design for Manufacturing principles, including tolerancing for plating and other production processes.
•
Adapt hardware and design test structures for air-bearing, zero-gravity flight, and thermal-vacuum testing across multiple orientations and environments.
•
Analyze test data, root-cause mechanical failures, and implement design improvements that move each prototype iteration closer to flight readiness.
What It Takes:
•
Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or a related field.
•
3–5 years of relevant mechanical design, mechanism design, or aerospace engineering experience.
•
Demonstrated experience designing precision mechanisms or complex mechanical assemblies—not solely CAD modeling or drafting.
•
Advanced proficiency with SolidWorks, GD&T, tolerance stack-ups, and detailed manufacturing drawings.
•
Experience designing rotary components and selecting bearings, motors, gearboxes, springs, fasteners, or related components.
•
Experience with vibration, structural design, test-fixture development, and Design for Manufacturing.
•
Hands-on experience conducting tests in a laboratory or R&D environment, analyzing results, and implementing design changes.
•
Ability to work with limited direction and obtain and maintain a U.S. Government security clearance.
What We’d Love:
•
Experience selecting and designing with space-grade components.
•
Experience designing mechanisms for testing or operation in space environments.
•
Experience developing spacecraft or launch-vehicle systems.
•
Experience taking mechanism designs from CAD through fabrication, assembly, and testing.
Where You’ll Be:
•
The position will be on site at our headquarters in El Segundo, CA.
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
