What are some typical challenges faced by a Day Thermal Engineer and how are they addressed within a team setting?

Day Thermal Engineers often encounter challenges related to managing thermal loads and ensuring system components remain within safe operating temperatures, especially in dynamic environments such as manufacturing plants or data centers. To address these issues, engineers collaborate closely with mechanical, electrical, and controls teams to analyze real-time data, troubleshoot anomalies, and implement rapid solutions. Regular team meetings and clear communication channels are essential, as they allow for swift sharing of insights and coordinated responses to any emerging problems, helping maintain optimal system performance and safety.

What are the key skills and qualifications needed to thrive as a Day Thermal Engineer, and why are they important?

To thrive as a Day Thermal Engineer, you need a solid background in mechanical or thermal engineering, heat transfer, and thermodynamics, typically supported by a relevant engineering degree. Familiarity with thermal simulation software (such as ANSYS or COMSOL), CAD tools, and possibly certifications like Professional Engineer (PE) can be highly beneficial. Strong problem-solving skills, attention to detail, and effective communication are important soft skills for collaborating with multidisciplinary teams and presenting technical findings. These skills and qualifications ensure accurate thermal analysis, effective system design, and reliable project outcomes in industries where temperature control and thermal management are critical.

What is the difference between Day Thermal Engineer vs Night Thermal Engineer?

AspectDay Thermal EngineerNight Thermal Engineer
CredentialsBachelor's degree in Mechanical or Thermal Engineering, relevant certificationsSame as Day Thermal Engineer
Work EnvironmentStandard daytime hours, office or lab settingNight shifts, similar environments
Industry UsageCommon in manufacturing, HVAC, automotive industriesLess common, used in 24/7 operations like data centers or manufacturing plants

The main difference between a Day Thermal Engineer and a Night Thermal Engineer lies in their work shifts. Both roles require similar qualifications and work in comparable environments, but they operate during different times of the day to support continuous operations or specific project needs.

What does a Day Thermal Engineer do?

A Day Thermal Engineer is responsible for managing and optimizing thermal systems and processes during daytime operations in various industries, such as manufacturing, energy, or technology. They analyze heat transfer, energy efficiency, and thermal performance to ensure systems run safely and effectively. Their tasks may include designing thermal management solutions, troubleshooting temperature-related issues, and collaborating with other engineers to improve product or process performance. Day Thermal Engineers often focus on maintaining comfortable and efficient working environments or optimizing equipment that operates primarily during the day.

Job description

Thermal Engineer

Who Are We:


Sceye is a high-growth technology company, building the next generation of instant communications, imaging and remote sensing infrastructure through stratospheric platforms. Our lighter-than-air high-altitude platform systems (LTA HAPS) are capable of maintaining position over an operational area in the stratosphere (altitudes of 18 – 21km). They can carry multiple telecommunications, imaging and remote sensing payloads, providing unique functionality, cost, environmental and societal advantages.

Our HAPS can be deployed in a matter of days and at a fraction of the cost of traditional infrastructure solutions. This makes them an ideal solution for providing telecommunications connectivity, emergency solutions in the event of natural or other disasters, environmental and infrastructure monitoring, Earth observation and a range of defense applications.

Our customers & partners include some of the largest global telecommunications companies, infrastructure operators, climate researchers, civil and defense agencies. At Sceye, we aim high, and we want you to join us at the stratospheric edge of innovation. As part of our mission-driven team, you’ll contribute to building breakthrough technologies that are changing the way we connect and observe the world. We are looking for individuals who bring not only deep expertise but also bold vision and an unwavering commitment to excellence.

About the Position:


Sceye is seeking a Thermal Engineer to join our Avionics Hardware (HW) team. This role is responsible for the thermal design, analysis, and validation of avionics hardware operating in a challenging stratospheric environment. The ideal candidate will collaborate closely with electrical, mechanical, systems, and flight operations teams to ensure avionics performance, reliability, and safety across all mission phases.

What We’re Looking For:

  • Lead thermal analysis and design for avionics hardware, including PCBs, enclosures, and integrated avionics assemblies.
  • Develop and validate thermal models using analytical and numerical methods (e.g., conduction, convection, radiation).
  • Perform steady-state and transient thermal analyses to support design decisions and mission requirements.
  • Define thermal requirements and margins for avionics systems operating in high-altitude, low-pressure, and extreme temperature environments.
  • Support hardware layout and enclosure design to optimize heat dissipation and component placement.
  • Specify and evaluate thermal management solutions, including heat sinks, thermal interface materials (TIMs), coatings, and passive/active cooling approaches.
  • Plan, support, and analyze thermal testing (e.g., thermal vacuum, thermal cycling, environmental testing).
  • Correlate test results with models and update analyses as designs evolve.
  • Support design reviews (PDR, CDR) with clear documentation and technical presentations.
  • Collaborate with systems engineering to ensure thermal performance aligns with power, reliability, and mission requirements.
  • Contribute to failure analysis, root cause investigations, and corrective actions related to thermal issues.

Required Qualifications:

  • Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, or a related field.
  • 5+ years of experience in thermal engineering, preferably within aerospace, avionics, or high-reliability electronics.
  • Strong understanding of heat transfer principles (conduction, convection, radiation).
  • Experience performing thermal analysis of electronic hardware and assemblies.
  • Familiarity with thermal modeling and analysis tools (e.g., Thermal Desktop, SINDA/FLUINT, ANSYS, COMSOL, or equivalent).
  • Experience supporting environmental testing and correlating test data to analysis.
  • Ability to work cross-functionally with electrical, mechanical, and systems engineers.
  • Strong documentation, communication, and presentation skills.

Preferred Qualifications:

  • Master’s degree in Mechanical or Aerospace Engineering.
  • Experience with high-altitude, space, or near-space environments.
  • Knowledge of PCB thermal design and power electronics thermal management.
  • Experience with thermal vacuum (TVAC) testing and qualification programs.
  • Familiarity with aerospace standards and best practices for environmental qualification.
  • Hands-on experience with avionics hardware development from concept through flight.

What We Offer:


At Sceye, we’re building more than high-altitude platforms—we’re building a workplace where people (and their pups) thrive. Here’s what you’ll enjoy:


  • Chef-Prepared Lunches – Fresh, onsite meals to keep you fueled and focused.
  • Snacks & Refreshments – Enjoy a variety of snacks and drinks available throughout the day.
  • Wellness Perks – Access to a gym, pickleball court, and an outdoor dog kennel.
  • Dog-Friendly Environment – Bring your four-legged friends to work and enjoy a pet-welcoming space.
  • Comprehensive Health Coverage – Medical, dental, vision, and disability insurance, with over 82% of premiums covered—and 100% for everything else.
  • 401(k) with Match – Company contributions that are yours from day one.
  • High-Performance Culture – Join a collaborative, inclusive environment where your work helps shape the future of aerospace.
