Senior Materials Technician

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.

The Senior Materials Technician owns the daily movement, storage, and accountability of Portal’s flight hardware, raw materials, tools, equipment, and consumables. This hands-on role leads receiving, inventory control, kitting, and shipping while establishing practical processes that support a growing spacecraft manufacturer. Working with Supply Chain, Engineering, Build, Integration, and Test, this individual keeps materials available, traceable, and organized to enable the more efficient building of spacecraft.

Success means accurate records, dependable material flow, and clean, organized work areas where every item has a designated home.

• Manage shelf-life controls, stock rotation, and specified storage conditions. Monitor consumable levels and notify Procurement before shortages affect work.
• Protect hardware through appropriate packaging, electrostatic discharge controls, cleanliness practices, and foreign object debris prevention.

Kitting and Production Support

• Prepare and verify kits against approved bills of materials, work orders, or material requests, including required quantities, revisions, and traceability.
• Coordinate kit readiness and shortage priorities with Build and Supply Chain; stage and deliver material to support integration and test schedules.
• Record material consumption and unused returns promptly, maintaining separation between flight, development, and nonconforming hardware.

Shipping and Logistics

• Prepare protective packaging, labels, packing lists, and shipment records for supplier returns, outside processing, intersite transfers, and customer or test-site deliveries.
• Coordinate carrier pickups, deliveries, tracking, and proof of receipt with Supply Chain; maintain an orderly shipping and receiving area.
• Support shipment documentation and approved handling instructions. Coordinate export-controlled or hazardous shipments with authorized personnel and perform regulated shipping tasks only when trained and authorized.
