## About the Role

* BS or higher in mechanical engineering, aerospace engineering, or a related field.
 * Proven experience taking complex mechanical hardware from concept through released drawings, test, and validation.
 * Strong CAD skills (SolidWorks, NX, Onshape, CREO, or comparable) and GD&T per ASME Y14.5.
 * Practical knowledge of machining, fabrication, and assembly, and how design decisions affect manufacturability.
 * Sound judgment on how designs interact with structural, thermal, and sealing requirements.
 * Strong communicator who is eager to learn and to teach.

Preferred Experience

 * FEA, bolted joint analysis, and thermal growth assessment of mechanical hardware.
 * Elastic-plastic stress analysis, and creep or creep-fatigue assessment of high-temperature alloys.
 * Mechanical design for high-pressure, high-temperature systems.
 * Packaging machinery, piping, and balance-of-plant equipment onto skids or frames in a compact, buildable, serviceable layout.
 * Design of rotating machinery or turbomachinery hardware.
 * Startup or early-stage company experience.

## Description

* Own detailed mechanical design of the machine and supporting systems, including the turbomachinery test section, pressure boundary components, skid structure, and piping.
 * Produce released drawings with disciplined GD&T and drafting practice.
 * Work with vendors to bring designs from drawing to assembled hardware.
 * Manage interfaces and tolerance stacks across the machine so parts fit together cleanly.
 * Apply DFMA so designs work for early prototypes and for future production.
 * Partner with analysis teammates to verify the structural and thermal performance of your designs.
 * Assemble, build, and test the hardware you design.
