Mechanisms Engineer III — Opto-Mechanical Systems

Mechanisms Engineer III

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!

Blue Origin is pioneering the future of space-based communications with Tera Wave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.

The Emerging Systems business unit at Blue Origin is pioneering the future of space-based communications with Tera Wave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi-orbit constellation will consist of 5,408 optically interconnected satellites in low Earth orbit (LEO) and 128 satellites in medium Earth orbit (MEO), providing enterprise-grade connectivity for critical operations worldwide.

Blue Origin's Emerging Systems is seeking a driven Mechanisms Engineer III to join a small, fast-moving team developing precision mechanical systems for the Tera Wave constellation. On a lean team, you will personally own significant mechanism design scope end-to-end — from concept through qualification — with a high degree of autonomy and accountability for your hardware. You will work shoulder-to-shoulder with senior and principal engineers, but you will be the directly responsible engineer for the mechanisms you take on.

• Own the design and development of precision gimbal assemblies and pointing mechanisms for space-based optical communications terminals, from concept through flight qualification
• Develop and be accountable for mechanism-level performance requirements, error budgets, and design margins across structural, thermal, and dynamic domains
• Drive design trades for gimbal configurations, balancing mass, volume, stiffness, pointing accuracy, and on-orbit lifetime, and defend your recommendations in design reviews
• Plan and execute mechanism qualification including component- and system-level testing in shock, vibration, and thermal vacuum environments, and own the resulting data and corrective actions
• Author and maintain mechanism design documentation, analysis reports, and test procedures supporting hardware build and test
• Coordinate directly with cross-functional partners on mechanism integration, harness routing, and interface definition — acting as the point of contact for your hardware
• Partner with senior and principal engineers on the toughest technical problems, escalating risks early and proposing solutions
• Support production transition through tolerance analysis, DFM/DFA improvements, and direct supplier engagement
• Motor and encoder selection for precision drive systems
• Bearing selection, preload analysis, and lubrication strategies for space mechanisms
• Mechanism-level FMEA and reliability analysis

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Automotive or related technical field
• 5+ years of experience in precision mechanisms design for space, aerospace, or high-reliability applications
• Demonstrated ability to independently own the design, analysis, and qualification of gimbal assemblies, multi-axis pointing mechanisms, or similar precision mechanical systems
• Proficiency in 3D CAD software (e.g., Creo, NX, Solid Works) and finite element analysis tools (e.g., ANSYS, NASTRAN, Comsol)
• Working knowledge of mechanism kinematics, dynamics, and structural analysis
• Hands-on experience with space qualification testing including vibration, shock, and thermal vacuum
• Experience with bearing systems, drive trains, or precision actuators for space mechanisms
• Solid understanding of GD&T, tolerance stack-up analysis, and interface control documentation
• Familiarity with Design for Manufacturing (DFM)…
