Jettison Design Engineer, Glenn xInterstage

Position: Jettison Design Engineer, New Glenn 9x4 Interstage
Application close date:

Applications will be accepted on an ongoing basis until the requisition is closed.

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!

This role supports the development and operations of New Glenn, a single-configuration, heavy-lift orbital launch vehicle capable of routinely carrying people and payloads to low-Earth orbit, geostationary transfer orbit, cislunar, and beyond. Its first stage is fully reusable, and the vehicle was designed from the beginning to be human-capable.

We are hiring a Responsible Engineer (RE) and Single-Threaded Leader (STL) for the Interstage Adapter Assembly (ISA) separation system on New Glenn Gen 2 (9x4 configuration). This person will own the full technical scope of the Gen 2 ISA separation system — from requirements through design, analysis, test, qualification, and flight certification. They will be the single point of accountability for separation system performance on the 9x4 vehicle and will lead a cross-functional team of analysts, designers, test engineers, and manufacturing engineers to deliver flight-certified hardware for Gen 2's first flight and beyond.

Special Mentions:

Relocation provided

Travel expected as needed, up to 30% of the time Interviews will include a technical assessment

Strong preference to hire in Kent, WA Responsibilities include but are not limited to:

Technical Ownership of jettison system for the Interstage Adapter:

Separation system architecture — frangible joint, linear shaped charge (LSC), or similar release mechanism, initiation system, redundancy scheme, and separation plane definition

Pusher / kick-off system — pneumatic or pyrotechnic pushers providing post-separation relative velocity; force-time profile specification and hardware selection

Shock attenuation & management — defining shock isolation strategies for ISA-mounted components; specifying SRS environments at equipment interfaces

Separation sequencing requirements — defining timing, ordnance firing sequences, and GNCinterface requirements for stage separation

Structural interface — separation plane joint design, ensuring structural integrity under all flight load cases prior to separation

Lifecycle Ownership of all aspects of the Jettison System:

Requirements — derive separation system requirements from vehicle-level specs (separation velocity,tip-off rate limits, shock limits, clearance envelopes, reliability)
Design — lead trade studies and architecture decisions; own the separation system design solution and drawing tree Analysis — oversee explicit dynamics simulation (LS-DYNA), shock propagation analysis, structural margins, and environments definition; review and approve analyst work

Test — define qualification and acceptance test requirements; own test success criteria; lead test readiness reviews (TRR) and test anomaly resolution

Qualification — drive separation system qual program to completion; manage qual status and openwork through certification gates

Production — support manufacturing readiness; define acceptance criteria for flight hardware;disposition nonconformances on separation system components

Flight operations — support vehicle integration in Florida; own separation system constraints in countdown and flight rules; support post-flight data review

Cross-Functional Leadership (STL Role)
Lead a virtual team of 3–6 engineers (dynamics analysts, mechanical designers, test engineers, M&Pengineers) without direct reports — influence through technical authority

Coordinate across GNC, Avionics, Propulsion, and Flight Software for separation event sequencing and interface definition

Interface with GS1 Recovery team on post-separation booster state and refurbishment requirements

Drive decisions at design reviews (PDR, CDR, TRR, QR) and represent separation systems at vehicle level review boards

Own the separation system schedule — identify long-lead items, qual risks, and critical path activities;…
