About the Role

We are seeking a Senior Thermal Engineer to join our team at York Space Systems LLC. This is a unique opportunity to work on cutting-edge spacecraft thermal engineering projects and contribute to the development of innovative space technologies.

Job Description

The successful candidate will be responsible for ensuring all satellite components function within specified temperature limits throughout the mission lifecycle. This position requires both hands-on technical expertise and an ability to mentor junior team members, making it ideal for an engineer with aspirations in technical leadership or management.

Key Responsibilities
  • Conduct detailed thermal analysis and simulation to optimize thermal control solutions for small satellite systems, ensuring components remain within operational temperature ranges.
  • Define and validate radiator/heater sizing and select external coatings for thermal management across all mission phases.
  • Collaborate with hardware developers to recommend appropriate materials, processes, and tests aligned with thermal design and mission requirements.
  • Coordinate with subsystem leads to manage thermal interfaces, ensuring proper integration across the spacecraft's systems.
  • Provide thermal requirements and environmental conditions to component suppliers, ensuring compatibility and reliability within the spacecraft's thermal design constraints.
  • Develop comprehensive test and verification protocols, including thermal vacuum and thermal balance testing, to validate thermal designs at the component and system levels.
  • Utilize on-orbit data to analyze thermal performance, identify areas for improvement, and inform design adjustments for future missions.
  • Mentor junior engineers in thermal analysis techniques, test approaches, and thermal verification, fostering a knowledge-sharing culture within the team.
  • Lead thermal design reviews, and present findings to cross-functional teams and senior leadership, ensuring clear communication of technical choices and trade-offs.
  • Collaborate with project management teams to define project schedules and resource requirements for thermal engineering tasks, ensuring timely and efficient execution.
Requirements
  • Bachelor's degree in Aerospace Engineering, Mechanical Engineering, or a related field is required; a Master's degree is preferred.
  • Minimum of 7 years in thermal engineering, with a strong background in satellite or space systems. Experience with small satellite (SmallSat) or CubeSat thermal engineering is highly desirable.
  • In-depth experience with Thermal Desktop is required, 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.
  • AutoCAD, and other thermal analysis tools; experience with modeling software such as SINDA/FLUINT is a plus.
  • Comprehensive knowledge of spacecraft design, including satellite structures, thermal controls, propulsion, power systems, and avionics.
  • Demonstrated experience in integrated hardware/software verification and environmental testing, including thermal vacuum (TVAC) testing, thermal cycling, and on-orbit thermal performance assessment.
  • Proven ability to lead or mentor teams, especially in a technical or engineering environment, with a strong aptitude for project planning and task prioritization.
  • Excellent communication skills, with a demonstrated ability to convey complex technical information to both technical and non-technical stakeholders.
  • Must be eligible to obtain a security clearance, and willing to undergo the necessary background checks.
