Thomas Instrument is an equal opportunity employer and will provide equal employment opportunity to employees and applicants for employment and will not discriminate against employees or applicants on the basis of race, ethnicity, religion, color, sex, pregnancy, national origin, age, military veteran status, ancestry, sexual orientation, gender identity or expression, marital status, family structure, genetic information, mental or physical disability, or any other legally protected status.

Thomas Instrument has a friendly atmosphere, an outstanding safety record, and a stable workload (no one large contract, but a multiple and varied customer base) with a strong international reputation for quality and integrity. The company has two plants with all benefits available including immediately vested 4% match to 401k.

The EDM Machinist is responsible for the setup, operation, and inspection of Electrical Discharge Machining (EDM) equipment used to produce precision aerospace components. This role requires machinist-level experience, including the ability to independently interpret prints, hold tight tolerances, and troubleshoot processes. In addition to EDM responsibilities, this position will support CNC machining operations—including mill, lathe, and grinding—based on production demand. This is not a trainee role;

candidates must be capable of contributing immediately in a high-precision manufacturing environment.

• Set up and operate EDM equipment (wire and/or sinker) to produce aerospace components to print
• Select and prepare electrodes, establish offsets, and adjust burn parameters for optimal performance
• Interpret complex engineering drawings, GD&T, and work instructions
• Maintain tight tolerances and required surface finishes
• Perform in-process and final inspections using precision measuring equipment
• Troubleshoot machining issues and adjust processes to maintain quality and efficiency
• Support CNC mill and lathe operations (setup, operation, basic program edits, and deburring)
• Assist grinding operations (OD//surface) as needed
• Support first article inspections and in-process quality checks
• Shift between departments based on workload and production priorities
• Accurately complete routers, work orders, and required documentation
• Follow all quality standards in an AS9100 environment
• Adhere to safety requirements and ITAR-controlled processes
• Contribute to "quality at the source" and continuous improvement initiatives

• Strong hands-on EDM machining experience (wire and/or sinker)
• Solid CNC machining fundamentals (mill and/or lathe)
• Ability to independently read and interpret blueprints and GD&T
• Proficient with precision measuring tools (micrometers, calipers, indicators, etc.)
• Ability to hold tight tolerances and produce repeatable results
• Troubleshooting mindset with the ability to adjust machining processes
• Aerospace manufacturing standards and expectations (AS9100 preferred)
• Material properties and behavior during EDM and machining (tool steels, nickel alloys, etc.)
• Understanding of feeds, speeds, offsets, and machining parameters
• Familiarity with shop floor systems (routers, work orders, inspection records)
• 3+ years of EDM machining experience preferred
• Prior CNC machining experience (mill, lathe, or grinding) required
• Aerospace or high-precision manufacturing experience strongly preferred

• Ability to regularly lift, carry, and move items up to 50 pounds
• Comfortable working in high-temperature and industrial environments
• Ability to stand, walk, bend, and reach for extended periods of time
• Exposure to machine shop conditions (coolant, oil, noise)
