Job Description

Job Description
Your day at a glance

You start by reviewing a new Technical Data Package (TDP) and the contract requirements. You translate both into clear routings and business-system entries, then open your preferred CAD/CAM suite to build efficient, reliable CNC programs for complex, tight-tolerance components. Before lunch, you select cutting tools, design or refine a custom fixture, and head to the floor to perform a critical setup. You qualify the process, capture learnings, and hand off a proven method to the machinist who’ll run production.

Later, you walk a cell to spot waste, proposing a lean tweak that trims cycle time and improves repeatability. An engineer swings by with a question about sampling plans; you coach them through the approach. Before you wrap, you support an estimate for a new RFQ, validate process risks, and ensure every step aligns with customer, solicitation, and contractual requirements.

What you’ll own
  • Develop robust manufacturing methods and sophisticated CNC programs for precision-machined parts.
  • Select tooling strategies and design/support fixturing to secure quality and throughput.
  • Perform crucial machine setups; qualify and transfer proven processes to machinists.
  • Champion process improvements and lean initiatives to reduce waste and variation.
  • Mentor engineers, machinists, and peers; serve as the go-to for programming and machining best practices.
  • Contribute to quality planning activities, including sampling plans and control strategies.
  • Support estimating for new work and partner on process engineering tasks.
  • Translate contractual and TDP requirements into the business system and ensure compliance.
  • Tackle additional technical tasks to meet business needs with minimal supervision.
What you’ll bring
  • BS in Manufacturing Engineering (or related field) or equivalent experience; typically 5–7+ years in CNC manufacturing.
  • Deep knowledge of manufacturing processes, machining methods, and modern tooling technologies.
  • Proficiency with CAD/CAM platforms and hands-on experience on the shop floor.
  • Familiarity with sampling plans and techniques.
  • Experience with aerospace and/or DoD manufacturing preferred.
  • Comfort with MS Office for documentation, analysis, and communication.
  • Working knowledge of Quality systems and standards, including ISO 9001 and AS9100.
  • Understanding of government contracting requirements.
  • Collaborative mindset and the ability to thrive in a team environment.
