Job Schedule: 9/80: Employees work 9 out of every 14 days – totaling 80 hours worked – and have every other Friday off

 

Job Description:

L3Harris Technologies has an immediate opening for a Specialist Mechanical Thermal / Structural Analysis Engineer to join our team in Orlando, FL. Coleman Aerospace produces complex single, two, and three-stage air-launched target vehicles used to support ballistic missile defense testing and is the Aerojet Rocketdyne segment Center of Excellence for Undersea Propulsion manufacturing.

We are seeking a self-motivated individual contributor with strong thermal and structural analysis skills to support large, complex project initiatives of substantial importance to the organization, and to serve as the thermal Subject Matter Expert (SME). The ideal candidate will work under general oversight and provide guidance to more junior analysts. Our small team and fast-paced atmosphere demand the ability to devise simple solutions to complex engineering problems, both independently and by soliciting input from technical SMEs across the organization. This position may require occasional overtime and travel to meet critical schedule milestones.

 

Essential Functions:

  • Perform structural and thermal static and dynamic analyses at both the launch vehicle (LV) and component levels using classic hand calculation methods and finite element models.
  • Provide support to structural dynamics and thermal testing activities (thermal cycle, TVAC, vibration, shock, acoustic etc.) and assess measured data against requirements. 
  • Analyze dynamic response data from launch vehicle missions to define thermal and dynamic environments.
  • Correlate analysis models and test results.
  • Provide assessment of the products ability to satisfy internal thermal and structural requirements as well as those flowed by the customer.
  • Report status and results of analysis tasks at team meetings, design and program reviews.
  • Prepare technical reports documenting all analysis activities.
  • Travel may be required but typically less than 10%

 

Qualifications:

  • Bachelor’s Degree in Engineering and minimum 6 years of prior relevant Mechanical Engineering 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.

Preferred Additional Skills:

  • Solving thermal and structural analysis problems across the target launch vehicle organization by providing support to resolve our most challenging problems that can include the following topics; aerothermal analysis, component thermal analysis, stress analysis, loads analysis, vibration and shock analysis, environments derivation, flight data reduction, and fracture mechanics.
  • Support innovative solutions and understand the balance between engineering judgment versus analysis rigor and when each is appropriate.
  • Demonstrated experience working in several of the following areas:
    • LV or airframe aerothermal analysis
    • Electronic box leve
