Senior Specialist, Mechanical Engineering (Thermal)

L3Harris is seeking a Thermal Analyst for spaceborne precision optics, mirrors and cryogenic optical systems for IR payloads. This role includes completing thermal analysis of entire payloads as well as detailed module analysis and support of the thermal architecture development and supporting trade studies. This role will include leading small teams of thermal analysts in accomplishing the above assignments. The role includes thermal analysis of circuit cards and chassis with medium to high thermal density in Spaceborne applications.

Essential Functions: 

• Responsible for thermal analysis of precision optics for IR payloads including optical mirrors, mirror mounts, windows, filters, focal plane mounts and telescopes for cryogenic applications.
• Collaborate with design engineering and test engineering for the build and test of subsystems and payloads.
• Leadership of thermal analysis teams for IR payloads and mechanical subsystems
• Author thermal analysis sections of PDRs, CDRs, and other required design reviews
• Author thermal analysis sections of CDRL’s and SDRL’s and other compliance documents for customers.
• Assist with schedule, cost, and technical leadership of major subsystems and payloads
• Complete cost estimation of thermal analysis BOE’s for proposals
• Participate in risk assessment and development of mitigation strategies for complex optical payloads.
• Collaborate across functions to minimize gaps in requirements, responsibilities and payload performance.
• Ability to obtain and maintain DOD Security Clearance
• Up to 20% of travel may be required

Qualifications: 

• Bachelor’s Degree in STEM and minimum 6 years of prior relevant experience. Graduate Degree and a minimum of 4 years of prior related experience. In lieu of a degree, minimum of 10 years of prior related experience.
• 4+ years experience in thermal analysis and testing for space environments (temperature and vacuum)
• Experience with thermal analysis of optical elements for optical distortion due to thermal stresses
• Experience with leading thermal vacuum test events and fixture analysis efforts
• Experience with Thermal Desktop (TD) thermal analysis tool
• Experience in 3D CAD design

Preferred Additional Skills:

• Experience with circuit card and chassis level thermal analysis for Space
• Experience with Creo 4or Solidworks
• Prior IR/cryogenic optical / thermal analysis experience including STOP analysis.
• Prior experience in developing thermal control structures and systems such as Radiators, heat pipes networks, thermal straps, cryocoolers or thermal sub-assemblies is strongly desired
• Prior experience doing thermal analysis of optical payloads supporting the optimization of heat rejection, power consumption and low mass.
