Mechanical Systems Engineer III

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!

The role is part of the In-Space Systems business unit, which is focused on addressing two of the most compelling challenges in spaceflight today: space infrastructure and increasing mobility on-orbit.

The role is part of the Blue National Security business unit, which is focused on delivering advanced space-based capabilities in support of national security missions. Within the Advanced Capabilities organization, this team operates at the forefront of mission engineering and architecture, developing next-generation space systems that address the most demanding and consequential challenges in the defense domain.

As a Mechanical Systems Engineer III
, you will play a hands‑on role in shaping the mechanical systems that enable Blue Origin's in‑space infrastructure and on‑orbit mobility missions. You'll apply engineering principles to design, analyze, and optimize mechanical hardware — from study‑level concepts through detailed CAD models — while contributing directly to payload accommodation solutions that balance mass, volume, and performance. Partnering closely with cross‑functional teams, you'll help resolve mechanical interface challenges, translate system‑level requirements into actionable design specifications, and support trade studies that shape critical design decisions.

This role offers the opportunity to build foundational systems engineering expertise while working on real aerospace hardware that supports humanity's expansion into space.
