Thermal Engineer – Space Systems

Company Details

Make the leap with us.

Tyvak needs an experienced Thermal Engineer. Thermal engineers are involved in all aspects of a spacecraft lifetime. They support spacecraft thermal systems configuration from concept level through design reviews, design verification, and operations. In addition to predictive and analytical work, Thermal Engineers may serve on-console during spacecraft test activities and/or operations which can include periods of off-hours or on call work.

Responsibilities include but are not limited to:

  • Work with a multidisciplinary team to reduce thermal risk by identifying the constraining elements of a thermal design and recommend mitigation strategies from concept level to design, production, and operation.
  • Work with spacecraft system engineers to reduce spacecraft CONOPS (Concept of Operations) into representative thermal design scenarios.
  • Develop thermal models of active and passive thermal designs using a mixture of numerical solutions and hand calculations of spacecraft systems, subsystems, avionics, and mechanisms that predict temperature margins in a variety of space thermal environments.
  • Prepare technical documents and PowerPoint presentations, develop thermal verification test plans and support test activities, monitor and correlation test results to model predictions.
  • Develop summaries to present results of analysis and tests to Managers, Customers, and/or Stakeholders.
  • Develop tools to support concept trade studies and post-processing analysis


  • To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
  • Minimum 1 years’ experience in thermal analytics utilizing a mixture of numerical and analytical techniques.
  • Must possess an understanding of the basic principles of radiation and conduction heat transfer in conjunction with space environment heating effects and parameters associated with spaceflight applications.
  • Proven knowledge of spacecraft mission design and associated subsystems.
  • Knowledge of environmental requirements, engineering, and testing and hands on engineering project experience including use of data acquisition systems.
  • Comfortable working in fast-paced, start-up environment with a strong desire to be a key contributor on a small team.
  • Highly responsible team player with positive attitude and excellent communication and documentation skills.
  • Experience with Solidworks or other CAD software
  • Master of Science degree (years of experience requirement reduced to 0 years with MS).
  • Experience developing detailed thermal and simplified thermal models for spacecraft systems, subsystems, and components.
  • Proficiency with computational scripting languages (Matlab, Python, Mathematica, etc)
  • Strong desire to develop tools to automate repetitive tasks that reduce analysis turnaround time
  • Proficiency with Thermal Desktop
  • Per the requirement of certain Tyvak facilities, applicant must be eligible to obtain and maintain a U.S. TS/SCI Security Clearance and all special accesses required to work at such facilities.

Educational Requirements:

  • Bachelor or Master of Science degree in Mechanical or Aerospace Engineering with Thermal focus (or similar).


  • Less than 5%. Will not be regularly required.
  • Occasional off-site testing support at local test facilities and to support program milestone reviews as needed.


  • Salary and benefits are market competitive
  • Competitive health benefits, including 100% Company-paid Medical, Dental, and Vision (PPO options available)
  • Generous Company-paid holiday schedule
  • Accrued Vacation and Sick Leave Time Off package for all full-time employees
