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
