Job Title: Systems Design Engineer 4 - Unmanned

Location: Ashburn, VA 

Job Description:

Let's start with who we are: Advanced Systems & Technologies (AS&T) division specializes in developing disruptive, next-generation technologies for advanced radar systems, next-generation weapon systems, and other RF sensor technologies. What does that mean? It means that as the non-traditional 6th prime, we're developing entirely new clean sheet designs. We aren't designing upgraded parts of an existing system. We are immersed in technology and we are technology driven. 

What's a day in the life like in this role? This is a systems engineering position, so the tasking is similar to what you've done before. But the difference is that you're working in a completely different culture and mission mindset. Our team sizes are smaller, allowing for collaboration, great ideas, and contribution from all levels in an agile product development environment. In other words, you're not stove-piped into one area, and instead can work the entire engineering lifecycle. You get to solve hard problems. Your day is spent working on new and exciting technology and methodology that hasn't been done before. You're inspired to do your best work every day, because what we do matters!

  • This position will be responsible for creating, maintaining and using requirements related documentation and databases for multiple programs
  • This position will be responsible for verifying all requirements are met using the approved verification method and documenting the verification results 
  • Coordinate with customer, subcontractor, and vendor personnel through written and oral communication.
  • Other duties as required


  • U.S. citizen
  • Active DoD clearance; must be able to obtain additional clearances as required
  • Bachelor’s degree in engineering or science
  • Minimum of 8 years’ experience in requirements development, design, implementation, integration and test of aerospace-related technical systems.
  • Minimum of 5 years of system level design experience in which the applicant has been involved in the design and integration of complex aerospace hardware/software systems, the definition of multiple interfaces, and been involved in the trades of multiple solution options
  • Minimum of 5 years of expertise in Systems Engineering disciplines and the government program acquisition lifecycle, to include requirements definition, creation of requirements verification test matrices, requirements decomposition, requirements traceability, design reviews and documentation, and integration and test
  • Proficiency with Microsoft Office products
  • Must be able to travel 15%; support field testing

Preferred Additional Skills:

  • Advanced degree
  • Possession of a current Top-Secret clearance is highly desirable
  • Degree or relevant coursework in Systems Engineering
  • Experience with proposal development including generating basis of estimates
  • Experience in unmanned aerial systems
  • Experience with Model Based Systems Engineering
