  • Experience supporting R&D, prototype builds, or low-rate production
  • Background working at a startup or small, fast-moving engineering company
  • Experience with supplier onboarding, vendor performance tracking, and strategic sourcing initiatives

What You’ll Get

  • Ownership – Own and operate the purchasing system and procurement processes that support spacecraft development and manufacturing
  • Impact – Enable engineers and programs to execute on schedule by ensuring critical components, materials, and services are sourced reliably and on time
  • Collaboration – Work directly with engineers, manufacturing, quality, and suppliers to solve real supply chain challenges tied to flight hardware

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
