Engineer How the Hardest Parts Get Made

We are an engineering-driven precision manufacturing organization supporting advanced aerospace and defense programs. Our work centers on complex 5-axis machining—tight tolerances, difficult materials, and NPI-heavy programs—executed on world-class equipment.

This is not a desk-only CAM role.

This role is for a Senior Manufacturing Engineer who wants full ownership of how parts are made—from CAD model through validated production—while working directly on the shop floor during setups, prove-outs, and first-run builds.

If you thrive where engineering decisions directly impact quality, cycle time, and execution, this role is built for you.

What You’ll Do

  • Program complex 5-axis CNC components using Siemens NX

  • Develop, optimize, and validate advanced multi-axis toolpaths for high-complexity parts

  • Support and troubleshoot machines running Siemens One and Heidenhain TNC 7 controls

  • Lead programming and process development for NPI, first-article builds, and complex production work

  • Own machining processes from model to metal

  • Collaborate closely with machinists, quality, and engineering during setups and prove-outs

  • Optimize cycle time, tool life, workholding strategy, and overall process stability

  • Create and maintain production-ready programs, setup documentation, and engineering standards

  • Support troubleshooting and continuous improvement initiatives on the shop floor

  • Identify process risks early and drive corrective actions before production impact

What We’re Looking For

  • Proven experience programming 5-axis CNC machining centers

  • Strong proficiency in Siemens NX (multi-axis, surfacing, complex toolpaths)

  • Experience supporting Siemens and/or Heidenhain CNC controls

  • Background in aerospace, defense, or other high-complexity machining environments

  • Strong understanding of GD&T, fixturing strategy, and material behavior

  • Comfortable working hands-on with machines, setups, and operators

  • Experience leading or owning programs, including project / program management

  • Ability to engage directly with internal stakeholders and external customers when required

  • U.S. Person eligible to work on ITAR-regulated programs

Physical Demands & Work Environment

  • Frequent standing and walking on the shop floor

  • Regular sitting while programming and reviewing models

  • Reaching, including overhead, during machine support and setup reviews

  • Occasional lifting up to 50 lbs (tooling, fixtures, components)

  • Work around large CNC equipment, moving machinery, and overhead cranes

  • Adherence to all safety procedures, PPE requirements, and safe-work practices

Safety Expectations

  • Maintain a strong safety-first mindset

  • Follow all company and regulatory safety procedures

  • Proactively identify and communicate potential safety or process risks

  • Lead by example during setups, prove-outs, and troubleshooting activities

What We Offer

  • $120,000–$140,000 base salary, depending on experience

  • Brand-new, climate-controlled facility with modern 5-axis equipment

  • Direct access to leadership—engineering has a real voice

  • Work on high-visibility, mission-critical aerospace & defense programs

  • Long-term growth with a company scaling thoughtfully and correctly
