Senior Thermal Engineer

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

Space Kinetic is looking for a Senior Thermal Engineer to assist with thermal analysis, hardware design , hardware acquisition , and test within the simulation group of the M echanical E ngineering department. The candidate will ensure that comp o nents will operate within safe temperature ranges despite the extreme thermal environment of space . The candidate will work on passive and active thermal control systems.

• Design, analyze, and test thermal hardware, including MLI blankets, heaters, heat pipes, sensors, vents, radiators, and surface coatings.
• Partner with mechanical teams to develop passive and active thermal-control systems.
• Plan, execute, and document TVAC, thermal-cycling, interface, and material-characterization tests.
• Validate and verify thermal designs through analysis and testing.
• Map thermal loads and temperatures onto structural finite-element models.
• Create drawings, analysis reports, test plans, procedures, reports, presentations, and other technical documentation.
• Build and maintain thermal-material databases and comprehensive parts lists using BOMs, drawings, supplier data, and technical databases.
• Collaborate with Structures, Electrical, GNC, Propulsion, Systems Engineering, Manufacturing, Production, and Integration and Test teams.
• Monitor component fabrication, integration, and testing through completion.
• Work independently, learn quickly, communicate clearly, and deliver accurate results in a fast-paced environment.

What It Takes

• Bachelor’s degree in Aerospace Engineering, Mechanical Engineering, or a related field,
• 5+ years of relevant space-industry experience designing spacecraft thermal systems from initial analysis through ground testing and on-orbit validation.
• Ability to develop and execute tests that validate hardware performance under extreme conditions.
• Hands-on experience with laboratory tools, spacecraft integration, and environmental testing.
• Proficiency with Thermal Desktop, SINDA/FLUINT, RadCAD, Siemens Space Systems Thermal, or similar tools.
• Understanding of orbital thermal environments and spacecraft heat-transfer principles.
• Experience designing or procuring MLI blankets and related thermal-control hardware.
• Ability to correlate thermal models with test data.
• Experience with CAD tools such as SolidWorks, Creo, or AutoCAD.
• Basic MATLAB or Python proficiency.
• Ability to obtain and maintain a U.S. Government security clearance.
• Must meet applicable U.S. Government export-control requirements.

What We’d Love

• Prior experience with spacecraft design
• Experience working on a launch vehicle or satellite development effort
• Experience in a startup or agile development environment
• Passion for the commercial and government space industry.

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
