- Advanced proficiency in CNC programming, including setup, operation, and modification of G-Code to optimize machine performance for complex parts
- Experience working with tight tolerances (±0.0005”), particularly for aerospace or high-precision industries
- Experience designing and manufacturing work holding and fixturing for complex and advanced hardware manufacturing and/or repairs
- Expertise in interpreting complex blueprints, GD&T, and technical drawings, with a deep understanding of tolerance stack-ups, feature relationships, and the application of advanced machining techniques
- Mastery in using precision inspection tools (micrometers, calipers, CMMs, surface gauges), including the ability to perform in-depth part inspections to verify critical dimensions and tolerances
- Experience leading or mentoring junior machinists, with a focus on improving shop efficiency, quality control, and process optimization
- Extensive knowledge of multiple CNC control systems, including Heidenhain, Haas, Fanuc, Siemens, and others
- Proven ability to troubleshoot complex machining issues, including machine breakdowns, tooling issues, and part non-conformances, while implementing corrective actions
- Strong project management and organizational skills, capable of overseeing multiple projects and ensuring deadlines are met in a high-stakes environment
- Continuous improvement mindset, with experience leading process optimization efforts, reducing cycle times, and improving overall shop productivity
Additional Information:
- Willingness to work flexible hours, including shifts, overtime, and weekends as necessary to meet production needs
- Ability to lift up to 25 lbs. unassisted and handle physical tasks such as standing, stooping, bending, and working in tight spaces for extended periods (8+ hours)
- Comfort with repetitive movements, including using hands to operate machinery, tools, and control devices in a fast-paced, high-noise environment
- Strong communication skills to collaborate effectively with team members and leadership
- Proficiency with standard manufacturing software (or shop-floor systems) to log job details and track part progress
