• Work safely every day: follow PPE and safety rules, use proper lifting techniques, keep machine guards in place, and maintain a clean, organized work area

Who you are:

• High School Diploma or GED from an accredited school or institution
• 5–8 years of manual machining experience, ideally in oil & gas, power, heavy equipment, or automation & controls
• Advanced knowledge of precision measuring tools, including dial and Vernier calipers, ID mics, depth mics, and ball mics
• Strong mechanical aptitude and comfort with various types of metal cutting machinery
• Ability to read, evaluate, and respond to product specifications and complex drawings, with solid quality control habits
• Effective verbal and written communication skills, plus basic math and computer skills
• Ability to lift at least 40 pounds and perform physical work involving standing, bending, and kneeling
• Adaptable in a team environment as work needs change
• Willingness to work overtime, weekends, and holidays as required
