Who We Are  

At Blue Origin, we envision millions of people living and working in space for the benefit of Earth.   We're   working to do that by making access to space cheaper and more reliable through reusable launch vehicles. Join our team of problem solvers as we add our next generation of launch vehicles and in-space systems to our fleet.  

The Role  

We are seeking a Mechanical   D esign Engineer to join our   team . The core challenge is achieving rotational performance at a scale an d   spee d   that has not been   d emonstrate d   befor e.  

This is a han d s-on   d etaile d   d esign role built for someone who thrives in rapi d   d evelopment cycles. You will   d esign, buil d , test, learn, an d   re d esign — repeat. Success is measure d   by har d ware on the test stan d   an d   d ata in han d , not by   d ocuments alone.  

Responsibilities  

• Own   d etaile d   mechanical   d esign of a high-spee d   rotor assembly inclu d ing structural members, retention features, balance provisions, an d   thermal management.  

• D evelop an d   iterate thermal management solutions  

• Un d erstan d   thermal an d   structural loa d s on the rotor; translate those into   d esign requirements an d   geometry constraints  

• Author   d rawings, G D &T, assembly proce d ures, an d   acceptance criteria with sufficient rigor to buil d   an d   test har d ware quickly  

• D efine an d   execute component- an d   system-level test plans; be present for test operations, tear d owns, an d   inspection  

• D rive rapi d   d esign-buil d -test cycles —   i d entify   failure mo d es early, propose tra d es, an d   execute changes fast  

• Coor d inate with manufacturing an d   supply chain to pro d uce har d ware on aggressive sche d ules   an d   rates   without sacrificing structural or thermal integrity  

• Participate in failure investigations an d   contribute to root cause analysis an d   corrective action  

Basic Qualifications  

• B.S. in Mechanical Engineering or closely relate d   fiel d  

• 3+ years of experience in mechanical   d esign of rotating machinery   

• D emonstrate d   un d erstan d ing of rotor structural mechanics, inclu d ing centrifugal loa d ing, retention   d esign, an d   fit/preloa d   strategies for components with thermal sensitivity  

• Proficiency   with 3 D   CA D   ( CREO, NX,   CATIA, Soli d Works, or equivalent) an d   d rawing/G D &T per ASME Y14.5  

• Experience authoring an d   executing har d ware test plans an d   participating   han d s-on in test operations  

• Experience   with   d esign for manufacturing an d   d esign to cost.  

• Comfortable with fast iteration:   d esigning to 80%, buil d ing har d ware, learning from   d ata, an d   rapi d ly incorporating fin d ings  

• Must be a U.S. citizen or national, U.S. permanent resi d ent, or lawfully a d mitte d   into the U.S. as a refugee or grante d   asylum  

Preferre d   Qualifications  

• Experience   d esigning integrate d   cooling features within rotating assemblies — internal flow passages, thermal interfaces, or con d uction paths un d er rotation  

• Familiarity   with high   an d   low-cycle   fatigue an d   fracture mechanics for rotating components   operating   at high peripheral velocities  

• Experience with composite or a d vance d   alloy materials in high-stress rotating environments  

• Backgroun d   in rapi d   har d ware   d evelopment programs with short   d esign-buil d -test cycles an d   frequent   d esign up d ates  

• Rotor d ynamics   experience — critical spee d   analysis, unbalance response, bearing loa d   estimation
