About Portal

Portal Space Systems is on a mission to expand humanity’s freedom of movement in space. We’re building the spacecraft that makes that mission possible. From our Bothell, WA headquarters, we design vehicles with the maneuverability, resilience, and adaptability needed for the next era of orbital operations. Every system we build is in service of a simple idea: space should be more accessible, responsive, and capable. Joining Portal means stepping into a team that believes in bold engineering, fast iteration, and the power of small groups to change what’s possible. If you want your work to directly shape the future of in-space mobility, join us.

  • Develop composite mirror architecture and sub-assemblies in partnership with designers and external partners
  • Select and manage partner vendors to develop demo units and prepare for production scaling
  • Own and simplify non-metallic polymers, bonds, and materials across multiple vehicles
  • Develop qualification and production test processes for primary and secondary non-metallic structures

 

Basic Qualifications

  • 3 + years of experience developing and testing composite structures, or similarly process-intensive assemblies in an engineering capacity
  • Experience steering the development and qualification of composite spacecraft structures
  • Direct experience working with suppliers or external partners to develop and deliver on complex composites needs
  • Experience supporting hardware qualification, integration, or development testing to meet aerospace standards (SMC-S-016 or similar specifications)

 

Preferred Skills & Experience

  • Deep knowledge of polymers, coatings, and processes as applicable to spacecraft and the space environment
  • Functional proficiency with NX (or similar CAD), as well as manufacturing planning and execution programs
  • Proven ability to communicate technical concepts clearly across engineering disciplines and external suppliers

Form CC-305

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.
