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:  We are seeking a Senior Machine Design Engineer to design, analyze, prototype, and validate complex machines, precision mechanisms, and electromechanical systems. This individual will apply first-principles engineering and practical machine-design experience to develop robust, manufacturable hardware for demanding aerospace environments. The role will work closely with engineering, manufacturing, test, suppliers, and program leadership to deliver flight-ready systems. Job Responsibilities: * Develop mechanical architectures and concepts for complex machines, precision mechanisms, structures, and assemblies.   * Own hardware from initial requirements and trade studies through detailed design, prototyping, qualification, and production.  * Perform engineering calculations covering stress, fatigue, deflection, thermal expansion, and tolerance stack-ups.  * Select and integrate bearings, motors, gearboxes, ball screws, linear guides, springs, clutches, fasteners, and related components.  * Create production-ready SolidWorks models, detailed manufacturing drawings, interfaces, and GD&T specifications.  * Apply Design for Manufacturing and Design for Assembly principles while working with suppliers and manufacturing teams.  * Build and test prototypes, root-cause hardware failures, and implement corrective design actions.  * Support qualification and environmental testing, including vibration, shock, and thermal-vacuum testing.   What It Takes:  * Bachelor’s degree in Mechanical Engineering or a related technical field.   * 5+ years of professional experience designing complex machines, mechanical systems, or precision mechanisms.  * Advanced proficiency in SolidWorks and experience creating detailed manufacturing drawings.  * Strong knowledge of machine design, mechanical component selection, GD&T, and tolerance analysis.  * Experience using hand calculations and FEA to guide and validate mechanical designs.  * Working knowledge of CNC machining, sheet metal fabrication, welding, additive manufacturing, and related production processes.  * Demonstrated experience taking hardware from concept through prototype, test, qualification, and production.  * Ability to maintain a U.S. Goverment security clearance.   What We’d Love: * Experience designing aerospace, spacecraft, defense, robotics, industrial automation, or other high-performance electromechanical systems.   * Experience with gear trains, linkages, cams, bearings, belt and chain drives, linear-motion systems, and direct-drive motors.  * Experience designing springs, dampers, or other energy-storage and motion-control mechanisms.  * Experience developing hardware for vibration, shock, thermal-vacuum, and other demanding environments.  * Familiarity with MATLAB or Python for engineering calculations and analysis.  * Experience supporting flight hardware qualification, configuration control, and production.   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 ITAR Requirements:   To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
