Lead 5-Axis Mill Programmer

The Lead 5-Axis Mill Programmer drives the manufacturing strategy and programming for critical, high-precision components used in space, aviation, and cryogenic LNG systems. The role combines advanced hyperMILL and/or Mastercam programming with technical leadership on the shop floor, including setup/prove-out of parts. You will develop collision-free, simultaneous 5-axis toolpaths for complex, tight-tolerance parts on our DN Solutions (Fanuc + Siemens) and Haas mills, and you will set the standard for how programs are built, verified, and proven out.

Key ResponsibilitiesMulti-Axis Programming

• Develop, simulate, and optimize 3-, 4-, and simultaneous 5-axis programs for DN Solutions and Haas mills using hyperMILL and/or Mastercam.

• Program complex parts, spanning industries such as aerospace, cryogenics, satellite components, and industrial.

• Apply advanced toolpath strategies that optimize material removal rates while achieving tight tolerance requirements.

Process Design and Workholding

• Design fixtures and workholding as-needed for tight-tolerance machining of large or complex billet parts.

• Select cutting tools, fixtures, feeds, and speeds for various materials (primarily aluminum and bronze, but also steels, stainless steels, titanium, and super alloys).

Verification and Prove-Out

• Verify every program in machine simulation before release.

• Lead first-article prove-outs on the shop floor, working directly on setups.

Technical Leadership and Compliance

• Mentor machinists on multi-axis techniques, setups, and G-code troubleshooting.

• Set programming standards and review programs before they are released to the floor.

• Work with production and quality to prioritize the programming queue.

• 7+ years of CNC programming experience, including at least 3 years of simultaneous 5-axis milling in an aerospace, space, or high-pressure energy environment.

• Advanced, hands-on proficiency in hyperMILL and/or Mastercam.

• Experience programming and running DN Solutions (3-axis Fanuc, 5-axis Siemens) and Haas multi-axis machines and controls.

• Strong command of GD&T and experience designing fixtures and workholding.

• Working knowledge of AS9100 quality processes.

• This position requires access to technical data and hardware controlled under the International Traffic in Arms Regulations (ITAR). Applicants must be U.S. persons as defined by 22 CFR 120.62.

• 401(k)
• Paid time off

For over 40 years, Dolphin Machine has built a reputation for delivering tight-tolerance, precision-engineered components for aerospace, space, energy, and industrial customers. Our machinists, programmers, and inspectors work in a fast-paced, quality-driven environment where execution and accountability matter.

We continue to invest in modernization and cutting-edge technology. Over the past 18 months, Dolphin has added more than $2 million in new CNC mill and lathe equipment. We are a hands-on manufacturing business focused on delivering mission-critical parts on time, and we are looking for a Lead Programmer who shares that mindset.
