  • Present designs and results at internal and customer reviews, including peer reviews, PDRs, and CDRs.
  • Partner with manufacturing, quality, configuration management, suppliers, technicians, and the program test team to transition designs into production.
  • Support field-test or demonstration activities as needed.
  • Ability to work on-site in a mix of office and laboratory environments.

Qualifications:

  • Bachelor's Degree 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. 
  • Active Top Secret or Top Secret/SCI clearance is required. (Active within the last two years will be considered).

Preferred Additional Skills: 

  • Hands-on experience designing, developing, integrating, and testing complex mechanical hardware.
  • Experience with 3D mechanical CAD, engineering drawings, and tolerance analysis/GD&T.
  • Experience in design or development of precision mechanisms, mechatronic systems, and/or packaging of modules and electronics with considerations of thermal and structural loading and for optimizations of size, weight, and power.
  • Proficiency in CAD tools such as Creo and understanding of ASME Y14.5 Geometric Dimensioning and Tolerancing standards.
  • Experience in additive manufacturing, part optimization, and design for manufacture and assembly a plus.
  • Experience with any of the following: actuators, custom gear trains, electro-optical systems, materials testing, and manufacturing processes.
  • Favorable polygraph.

In compliance with pay transparency requirements, the salary range for this role in California, Massachusetts, New Jersey, Washington, and the Greater D.C, Denver, or NYC areas is $102,000 MIN - $189,500 MAX.
