Thermal Engineer II

York Space Systems is looking for a talented Thermal Engineer II who specializes in thermal design and analysis to ensure all satellite components remain within their temperature limits throughout a mission's life cycle. This role is ideal for candidates passionate about using on-orbit data to refine future mission designs and capable of developing empirical tools to support similar system designs.

• Perform comprehensive thermal analyses to determine radiator and heater sizing, select appropriate external coatings, and ensure all spacecraft components remain within thermal limits.
• Collaborate with hardware developers to select materials, processes, and testing protocols that meet thermal design specifications.
• Establish and manage thermal interfaces among various spacecraft subsystems to ensure compatibility and functional integration.
• Communicate and enforce thermal interface and environmental requirements to suppliers and contractors for component compliance.
• Design and implement test and verification plans for thermal validation, establishing proper verification levels for spacecraft components.
• Coordinate across engineering on clean sheet designs and design improvements.
• Interface directly with programs and the end customer on high level and detail level design needs and requirements.
• Support peers through checking and collaboration to ensure best practices is implemented on all products developed within the team.

• Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field is required; a Master’s degree is preferred.
• Minimum of 2+ years in spacecraft thermal engineering or a closely related field with demonstrated expertise in thermal analysis, component design, or thermal testing.
• Experience with Thermal Desktop is strongly preferred as this tool is a core part of the job. Candidates should be able to perform thermal analysis, model thermal environments, and optimize spacecraft design using this software.
• Understanding of heat transfer principles, thermodynamics, and their applications in spacecraft systems.
• Strong interpersonal skills to work effectively within cross-functional teams and communicate complex technical information clearly to diverse audiences.
• Ability to convey design decisions, analysis conclusions, and recommendations meaningfully across departments.
• Experience with configuration control, the lifecycle of a design release and product lifecycle management.
• Demonstrates self-initiated work in a team environment with an ability to work independently.
• Possession of a US government security clearance or an ability and desire to obtain one.

• Experience with integrated software/hardware verification and testing for spacecraft is a plus.
• Familiarity with the entire spacecraft development lifecycle, from initial concept through final mission execution in orbit.
