Job Description

L3Harris has an opportunity for a highly skilled Thermal Analyst to join our talented engineering organization. The Thermal Analyst will be a technical leader across multidisciplinary teams of engineers to create the best overall system design including thermal design, analysis, and test of optical systems operating in harsh space and ground environments. The candidate will possess in-depth understanding of aerospace thermal engineering technology and payload architecture for spacecraft sub-systems and instruments. These talents are used in conductive, convective, and radiative analyses, understanding of heat pipes, radiative heat transfer, and thermal control hardware design (thermal blankets, surface treatments, heater tapes, thermistors) and the interaction with optical structures in order to minimize optical errors, and achieve operational temperatures. The role requires utilizing state of the art custom software in conjunction with Thermal Desktop and Finite Element Analysis (FEA) packages and often mentor other Thermal Analysts in the use of such tools.

Essential Functions

• System level thermal design & development, payload level integration and test, and risk mitigation for space-based environments
• Performs thermal design and analysis tasks on complex space-based mechanical hardware including structural components, mechanisms, and electronics packaging
• Create and analyze design concepts using thermal analysis software & FEA.
• Defines and establishes the technical approach to meet assigned objective.
• Program support which includes requirements derivation and verification, system architecture development, loads derivation, trade studies, design sensitivity/optimization studies, preliminary and final design analysis, generation of analysis documentation (including presentation materials, and deliverable data packages), and leading system test activities
• Prepares reports, formal documentation and presentation materials summarizing analysis results and present results to both external and internal groups, including leadership and customers.
• Participates in and present information for Preliminary Design reviews (PDR), Critical Design Reviews (CDR) and Technical Interchange Meetings (TIM).
• Interfaces with outside suppliers/customers and other engineering disciplines to drive designs to closure (Structural, Systems Engineering, Electrical, Manufacturing, Performance, Quality, Configuration Management).
• Development of thermal test plans to manufacture and test payload sensor systems
• Support new business opportunities
• Work multiple tasks in a fast-paced environment and adapt quickly to changing situations
• Ability to obtain and maintain a U.S. TS/SCI security clearance.

Qualifications

• Bachelor’s degree in Mechanical Engineering or a related engineering or science field with 6 years of experience, or a master’s degree in Mechanical Engineering or a related engineering or science field with 4 years of experience. In lieu of a degree, minimum of 10 years of prior related experience.
• 3+ years of professional experience using thermal analysis tools such as Thermal Desktop (required) and other tools such as FloTHERM.
• 3+ years of professional experience leading a multidisciplinary mechanical engineering team through system requirements, design, analysis, testing, hardware build, delivery, and launch.
• Professional experience performing thermal analysis of mechanical and electronic systems in space environments

Preferred Additional Skills

• Experience supporting programs through requirements derivation and verification, system and component architecture development, design sensitivity and optimization studies, preliminary and final design analyses, report generation, and leading test activities.
• Experience preparing reports, formal documentation, and presentation materials that summarize analysis results for both internal and external audiences, including leadership and customers.
• Experience working with outside suppliers, customers, and cross-functional engineering teams, including Structural, Systems, Electrical, Manufacturing, Performance, Quality, and Configuration Management.
• Thermal test experience, including Thermal Vacuum (TVAC) and Thermal Cycle testing, with involvement in test design, procedure development, test analysis, onsite test support, and thermal model correlation.
