Why This Role Exists

Synkronos is a small but rapidly growing aerospace manufacturing and engineering company expanding to support major new programs. The company is preparing to launch a $45M project while already executing additional multi-million-dollar work.

This role plays a critical part in building helicopters and next-generation flight vehicles from scratch. You'll work directly with ownership and help create machining processes from print through finished component.

This is not a production button-pushing role. You'll have ownership.

The Work You’ll Be Doing

In this role, you will:

• Take aerospace drawings from concept through finished part
• Program, set up, and machine complex components
• Develop tooling strategies and workholding approaches
• Create and optimize Mastercam multi-axis programs
• Edit programs and troubleshoot directly at the machine
• Interpret legacy drawings from the 1970s–1980s
• Collaborate closely with engineering and ownership
• Perform first-article and in-process verification
• Help shape machining processes as the company grows

Machines, Controls & Software

You’ll work with equipment such as:

Machines:

• Ibarmia ZVH 58
• Doosan Puma 5700
• Additional equipment added as growth continues

Controls:

• Fanuc
• Heidenhain

CAM Software:

• Mastercam Multi-Axis

Inspection Tools:

• Calipers
• Micrometers
• Indicators
• Precision inspection equipment

Materials You Will Work With

• Aluminum
• Stainless steel
• Aerospace alloys
• Prototype and flight‑critical materials

What We’re Looking For

Required:

• 7+ years CNC machining experience
• Programming and setup experience
• Ability to independently take parts from print to completed process
• Strong blueprint and GD&T skills
• Experience editing and troubleshooting programs
• Comfortable in prototype or high‑mix environments
• Ability to work from older engineering drawings
• Strong problem‑solving mindset

Preferred:

• Aerospace experience
• Multi‑axis machining experience
• Heidenhain experience
• Experience supporting prototype environments

Why Machinists Like Working Here

• Extremely small team where your work matters
• Direct access to ownership and decision‑making
• Flexibility with schedules and family commitments
• Real opportunity to help build a company
• Work on helicopters and flight vehicles from the ground up
• Mentorship and support from an owner who still programs and machines daily
• Fast growth and major projects already secured

Pay, Benefits & Schedule

Pay Range: $50–$65/hr DOE

Benefits:

Currently no formal benefits package, though leadership plans to add benefits as the company grows.

Schedule:

Monday–Friday
9:00 AM–5:00 PM

Flexible scheduling available:

• Need to drop kids off? No problem.
• Need flexibility around family responsibilities? The team works with people.
