About The Position

Relativity Space is building rockets to serve today’s needs and tomorrow’s breakthroughs. The Stage Manufacturing team turns design into reality, owning the build of Terran R’s primary structures. This role involves setting up and operating CNC machines with FANUC controls to produce parts per drawings and work instructions. It requires loading and adjusting tools, setting work and tool offsets, and verifying correct programs. The operator will read and interpret blueprints and basic GD&T symbols, perform first-piece and in-process inspections using basic measuring tools, and monitor machine operations, making adjustments as needed to maintain dimensional conformity, required surface finish, and cycle-time efficiency. Communication of issues to senior machinists or supervisors is also a key part of the role.

Requirements

Approximately 2+ years of CNC machining experience in a production, job shop, or similar environment.
Hands-on experience with FANUC controls (running programs, setting offsets, basic troubleshooting).
Ability to read and understand manufacturing drawings and use basic measuring tools.
Familiarity with machining different materials (e.g., aluminum, steel, stainless).
Basic understanding of cutting tools, speeds and feeds, and workholding.
Ability to follow instructions, ask questions when unsure, and work effectively in a team.
High school diploma or GED.

Nice To Haves

Technical/vocational training in machining preferred.
Experience with simple setups (e.g., vices, soft jaws, basic fixtures) with minimal supervision.
Exposure to tight tolerances and surface finish requirements.
Familiarity with ISO 9001 / AS9100 or other quality systems is a plus.
Basic experience with CAM programs or DNC systems is a plus.

Responsibilities

Set up and operate CNC machines with FANUC controls to produce parts per drawings and work instructions.
Load and adjust tools, set work and tool offsets, and verify correct programs are loaded.
Read and interpret blueprints and basic GD&T symbols to understand part requirements.
Perform first-piece and in-process inspections using calipers, micrometers, height gauges, and other basic measuring tools.
Monitor offsets, feeds, and speeds and make adjustments as needed to maintain dimensional conformity, required surface finish, and cycle-time efficiency.
Monitor machine operations, identify basic issues (tool wear, chatter, dimensional drift), and communicate problems to senior machinists or supervisors.
