Thermal Engineer – Space Systems

Company Details

Defining Agile Space


Tyvak Nano-Satellite Systems Inc. is a leading worldwide provider of nano- and micro-satellite vehicles, services, and solutions. Small satellites are disrupting the space technology realm by providing increased capabilities at a fraction of the cost of traditional programs.

Tyvak needs an experienced Thermal Engineer. Thermal engineers are involved in all aspects of a spacecraft’s 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 the 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, the 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 a fast-paced, start-up environment with a strong desire to be a key contributor on a small team.
  • Highly responsible team player with a 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 the analysis turnaround time.
  • Proficiency with Thermal Desktop.
  • Per the requirement of certain Tyvak facilities, the 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%. It 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 markets 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
