Senior CNC Programmer

Senior CNC ProgrammerMidland, Texas, United StatesAST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today's five billion mobile subscribers and finally bring broadband to the billions who remain unconnected.Position OverviewWe'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 ResponsibilitiesLead development, validation, and deployment of 5-axis CNC programs for CFRP production partsOptimize toolpaths for maximum throughput, minimal tool wear, and zero delaminationSelect and qualify advanced tooling (PCD/diamond) and fixture systems for compositesTroubleshoot process issues and implement permanent, data-driven solutionsDrive cycle-time improvements while safeguarding dimensional and cosmetic qualityStandardize programming practices, templates, and work instructionsMentor junior programmers and set programming performance benchmarksPartner with Engineering, Quality, and Production leadership to meet production targets and yield goalsQualifications10+ years CNC programming experience, with at least 5+ years on 5-axis millsDeep expertise in machining CFRP and advanced compositesMastery of CAM platforms (e.g., Mastercam, Autodesk (Inventor and Vault), AutoCAD, Fusion)Advanced understanding of feeds/speeds, tool geometry, work holding, and multi-axis simulationExceptional blueprint reading and GD&T skillsExperience in high-volume, production aerospace environmentsEducationHigh School Diploma or GEDExperienceA minimum of 10 years proven aerospace composite machining experiencePreferred QualificationsProven and demonstrated experience in machining with ceramic cutting tools, e.g., alumina, silicon carbideExperience with trimming, drilling, countersinking, and edge finishing of composite structuresKnowledge of dust extraction systems and composite safety protocolsFixture design and vacuum system design experienceSoft SkillsValues process control, repeatability, and lean production outcomesSees process improvements before problems occurMentors team members and elevate shop-wide capabilitiesComfortable setting standards and enforcing complianceStrong attention to detail and good verbal/written communication skillsProficient Microsoft Office skillsPhysical RequirementsStanding 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.This job description may not be inclusive to the duties and responsibilities listed.
