## About the role

Boom is building jet engines out of high-temperature superalloys, and every material decision we make - alloy selection, heat treat verification, allowables, failure analysis on parts pulled from our own test cell - depends on data generated in a materials lab. We're standing that lab up right now: mechanical testing (tensile, LCF, HCF, creep, high-temperature), metallography, and SEM.

## What they're looking for

- Plan and execute mechanical test campaigns on aerospace alloys: tensile (room and elevated temperature), LCF/HCF fatigue, and creep/stress rupture
- Work shoulder-to-shoulder with lab technicians and senior M&P engineers - everyone preps, everyone tests, everyone documents
- Write and validate the lab's test procedures against ASTM standards - then improve them
- Build the data backbone: specimen tracking, test logs, raw data pipelines, and reduction scripts that turn test output into design-usable material data
- Support metallographic evaluation and SEM inspection - microstructure verification, fractography, and failure analysis on engine hardware
- Support allowables-style test programs: test matrices, traceability, and statistical treatment of material property data
