Senior CNC Programmer

AST SpaceMobile and our global partners are building the first and only space-based cellular broadband network to be accessible by standard smartphones. Called SpaceMobile, this ultra-powerful network is being designed to provide connectivity at 4G/5G speeds everywhere on the planet – on land, at sea and in flight.

Position Overview

We’re scaling aerospace-grade CFRP production and we need an elite 5-Axis CNC programming expert to lead our high-volume, Class-A composite machining. This role is not “average programmer” - it’s for a strategic thinker and production optimizer who thrives in a fast-paced aerospace environment, drives standardization, and owns outcomes from CAD-to-finished parts.

Key Responsibilities

• Lead development, validation, and deployment of 5-axis CNC programs for CFRP production parts
• Optimize toolpaths for maximum throughput, minimal tool wear, and zero delamination
• Select and qualify advanced tooling (PCD/diamond) and fixture systems for composites
• Troubleshoot process issues and implement permanent, data-driven solutions
• Drive cycle-time improvements while safeguarding dimensional and cosmetic quality
• Standardize programming practices, templates, and work instructions
• Mentor junior programmers and set programming performance benchmarks
• Partner with Engineering, Quality, and Production leadership to meet production targets and yield goals

****Qualifications

• 10+ years CNC programming experience, with at least 5+ years on 5-axis mills
• Deep expertise in machining CFRP and advanced composites
• Mastery of CAM platforms ( e.g., Mastercam, Autodesk (Inventor and Vault), AutoCAD, Fusion)
• Advanced understanding of feeds/speeds, tool geometry, work holding, and multi-axis simulation
• Exceptional blueprint reading and GD&T skills
• Experience in high-volume, production aerospace environments

****Education

High School Diploma or GED

Experience

A minimum of 10****years proven aerospace composite machining experience

Preferred Qualifications:

• Proven and demonstrated experience in machining with ceramic cutting tools, e.g., alumina, silicon carbide
• Experience with trimming, drilling, countersinking, and edge finishing of composite structures
• Knowledge of dust extraction systems and composite safety protocols
• Fixture design and vacuum system design experience

****Soft Skills

• Values process control, repeatability, and lean production outcomes
• Sees process improvements before problems occur
• Mentors team members and elevate shop-wide capabilities
• Comfortable setting standards and enforcing compliance
• Strong attention to detail and good verbal/written communication skills
• Proficient Microsoft Office skills

**Physical Requirements**

• Standing and Walking: Frequently required to stand, walk, and work on foot.
• Lifting and Carrying: Must be able to lift, push, pull, or carry objects, often ranging from 20 to 50 pounds.
• Manual Dexterity: High level of dexterity required to handle, manipulate, and feel small, precise objects, tools, or machine controls.
• Physical Range of Motion: Frequent bending, stooping, kneeling, crouching, crawling, climbing, and reaching with hands and arms.
• Physical Stamina: Ability to endure long, 8-12-hour shifts, including working on foot in a shop setting.
