Our machine shop builds the precision components at the heart of this technology, and we're looking for an experienced machinist to help us deliver high-quality parts that move our mission forward. We're hiring an experienced CNC Vertical Machinist to set up, program, and operate CNC mills producing precision components to tight tolerances. You'll work from technical drawings, recommend tooling and machining strategies, run and inspect parts, and help prepare assemblies for hydrogen brazing. This is a hands-on role in a high-mix, low-volume environment where attention to detail and a drive to improve matter as much as raw experience.
WHAT YOU'LL DO
Review new projects and technical drawings to set up and program CNC machines. Adjust machine cutting paths and settings to optimize production while maintaining high-quality standards. Research and recommend tools necessary for cutting specific materials, and program machines accordingly. Conduct test runs and operate machines as needed to ensure quality production. Inspect parts and perform first-article checks to confirm they meet print and tolerance requirements. Assist in prepping assemblies for hydrogen braze and loading the furnace.Support general shop activities:
preventative maintenance, ordering tooling, prepping material, and small manual machining.WHO THRIVES HERE
Detail-oriented with a strong quality and safety mindset. Able to work independently with minimal supervision and juggle multiple jobs.

Proficiency with precision inspection tools—calipers, micrometers, height gauges, indicators, and gauge pins—to verify parts to spec. Solid shop math, including the trigonometry needed for offsets, geometry, speeds, and feeds. Clear communication, a strong desire to learn, and a commitment to continuous improvement. Willingness to learn and understand braze prep for hydrogen ovens.PREFERRED
Experience setting work and tool offsets, using edge finders, tool presetting, and on-machine probing. Experience with SolidWorks, including 3D modeling and drafting—not just reading 2D prints. 4th-axis or multi-axis machining experience. Manual machining skills (mill and/or lathe) for small jobs.
