About The Position

We are looking for an experienced Senior CNC Programmer to lead the development and execution of advanced machining processes for complex components. This role requires deep expertise in multi-axis programming and hands-on operation, along with the ability to support rapid iteration in a fast-paced R&D or flight development environment. The ideal candidate is highly technical, detail-oriented, and capable of driving parts from initial concept through stable, lights-out production.

Requirements

5+ years of CNC programming experience in a production or R&D environment
Strong hands-on experience with multi-axis machining (2-axis, 3-axis, 3+1 rotary, 5-axis, and mill/turn)
Proficiency with CAM software such as Esprit, or equivalent
Experience running lights-out production environments
Demonstrated ability to transition parts from first article to full production
Strong understanding of GD&T and tolerance stack-up analysis
Experience creating detailed setup documentation and process instructions
Must be a U.S. citizen or national, U.S. lawful, permanent resident (aka green card holder), Refugee under 8 U.S.C. § 1157, or Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.

Nice To Haves

Experience in a startup or agile development environment
Experience with Fanuc CNC controllers
Experience in an AS9100 (or similar) machining environment
Experience in fast-paced R&D or prototype-driven manufacturing environments
Familiarity with high-precision, tight-tolerance components
Experience machining high strength metallics, superalloys, and/or graphite

Responsibilities

Program, set up, and operate CNC mills and lathes across multiple configurations, including 2-axis, 3-axis, 3+1 rotary, full 5-axis, and mill/turn platforms
Interpret engineering drawings, applying GD&T principles and tolerance stack-up analysis to ensure part conformity
Develop, optimize, and troubleshoot CNC programs using CAM software such as Esprit, or similar
Determine cutting tool strategies for CNC programs
Generate and refine post-processed code to ensure efficient, safe, and repeatable machining operations
Create comprehensive setup sheets, tooling lists, and standardized work instructions for repeatable manufacturing
Lead machining process development from first article through full production readiness
Design and implement lights-out machining strategies, ensuring process stability and minimal operator intervention
Collaborate closely with design, manufacturing, and quality teams to resolve technical challenges and improve manufacturability
Identify and implement cycle time reductions, tooling improvements, and cost-saving opportunities
Support rapid prototyping and iterative development in an agile, high-mix/low-volume environment
