Fuelled by great people whose expertise and creativity sets the standards in our industry, we’re inspired by the opportunities to innovate and break boundaries. We’re proud to play a part in protecting the world’s democracies. And we’re committed to putting sustainability at the centre of everything we do, opening up and protecting our planet. With over 16,000 employees across 32 manufacturing sites in 12 countries we serve over 90% of the world’s aircraft and engine manufacturers and achieved sales of £3.6bn in 2025. There are no limits to where you can take your career.\nJob Summary\nCreate, verify, release, and continuously improve controlled CNC programs that safely and repeatedly produce conforming aerospace components, tools, and fixtures at the Garden Grove facility.\nProvide hands-on programming expertise across the Fadal, Heian, Onsrud, Thermwood, and Zimmerman machine fleet, using disciplined simulation, prove-out, documentation, and revision-control practices.\nPartner with Manufacturing Engineering, Operations, Quality, Tooling, Maintenance, and approved external specialists to improve machining capability while maintaining clear technical-authority and escalation boundaries.\nJob Responsibilities\n1. Safety, Compliance and Technical Control\nApply a safety-first approach to CNC programming, simulation, prove-out, program changes, and shop-floor support; stop and escalate work when conditions could compromise people, equipment, product, tooling, or the environment.\nFollow approved program naming, access, review, release, archive, backup, emergency-change, and revision-control requirements; verify that the shop-floor program matches the approved revision before production use.\nProtect export-controlled, proprietary, customer, and company information and follow all applicable site security, quality, environmental, health, and safety requirements.\nPerform work within assigned authority and escalate proprietary-control, machine-parameter, safety, quality, process-approval, or technical-authority decisions to the appropriate owner.\n2. CNC Programming, Simulation and Documentation\nPlan, create, verify, revise, and optimize machine-control data for multi-axis equipment used to manufacture and inspect complex aerospace parts, tools, and fixtures.\nDevelop safe and efficient toolpaths using approved CAM methods; complete machine simulation, collision and clearance checks, post-processed code review, and required peer or technical review before release.\nCreate and maintain complete shop-floor documentation, including setup sheets, tool lists, workholding and work-offset information, probing routines, operator notes, and revision history.\nSelect or recommend machining strategies, cutting tools, feeds, speeds, workholding, and probing approaches consistent with approved process requirements and machine capability.\n3. Prove-Out, Production Support and Problem Solving\nParticipate in controlled machine prove-outs, first-piece activities, and production introduction; document results, required changes, residual risks, and release evidence.\nDiagnose CNC program, post-processor, probing, simulation, setup-documentation, and revision issues using drawings, models, machine evidence, inspection results, and structured problem-solving methods.\nProvide structured support across assigned machines and shifts; communicate status, containment, risk, recovery needs, and escalation clearly through the machining operating cadence.\nLead or support root-cause analysis for recurring programming-related losses and implement verified corrective actions within authorized scope.\n(Cont...)\n4. Quality, Qualification and Configuration Management\nPartner with Quality and Manufacturing Engineering on producibility, measurement strategy, first article inspection, process qualification, and acceptance of new or revised programs.\nEnsure CNC programs and associated records support applicable drawing, GD&T, traceability, configuration, customer, and aerospace quality requirements.\nSupport containment and correction of programming-related nonconformances without bypassing independent Quality authority or required approval processes.\nPreserve objective evidence needed to demonstrate program verification, prove-out completion, qualification, revision status, and production readiness.\n5. Continuous Improvement and Standardization\nImprove first-pass quality, repeatability, cycle time, tool life, setup effectiveness, and machine utilization while following required change-control and process-approval practices.\nDevelop and maintain reusable programming templates, machining methods, post-processor knowledge, tool libraries, checklists, and lessons learned.\nUse data and practical Lean methods to identify recurring losses, reduce variation and waste, and sustain verified improvements in standard work.\nMaintain visibility of the assigned programming backlog and communicate priorities, technical risk, dependencies, completion evidence, and needed escalation.\n6. Machine Industrialization and Knowledge Transfer\nSupport Zimmerman and future machine industrialization, including post-processor readiness, program development, simulation, prove-out, tooling interfaces, probing, qualification evidence, operator support, and production handoff.\nCoordinate with equipment OEMs and approved external specialists while ensuring that decisions, methods, files, and lessons learned are documented and transferred to designated internal owners.\nCoach programmers, engineers, leads, and qualified operators on approved programming practices, safe program use, troubleshooting boundaries, and escalation requirements.\nCollaborate effectively across Operations, Manufacturing Engineering, Quality, Tooling, Maintenance, Planning, EH&S, and external technical partners.\nJob Qualifications\nAssociate degree in CNC programming, manufacturing technology, engineering technology, or a related technical field, or six years of directly relevant CNC programming experience in lieu of the degree.\nFive or more years of CNC programming experience supporting complex, tight-tolerance components in aerospace, defense, or another regulated precision-manufacturing environment.\nDemonstrated proficiency in multi-axis CAM programming, machine simulation and verification, collision avoidance, post-processed code review, and machine prove-out.\nWorking proficiency with CATIA and/or Siemens NX; Teamcenter or an equivalent product-data and configuration-control system; and VERICUT or equivalent CNC verification software.\nAbility to interpret engineering drawings and models, apply GD&T, select appropriate cutting tools and machining strategies, and create complete shop-floor documentation.\nDemonstrated ability to troubleshoot CNC programs, post processors, probing routines, simulations, setups, and revision issues using evidence and controlled problem-solving methods.\nAbility to work independently, manage multiple programming priorities, communicate technical risk clearly, and collaborate with Operations, Engineering, Quality, Tooling, Maintenance, equipment OEMs, and external specialists.\nAbility to work on-site in an active manufacturing environment and support the schedule required for assigned production, prove-outs, and machine introductions.\nMust be legally authorized to work in the United States. Where the position requires access to export-controlled information or items, the employee must be eligible for such access under applicable U.S. export-control requirements or receive any required authorization.\nPreferred Qualifications\nHands-on machining, setup, and prove-out experience on large-format, 5-axis, gantry, router, or comparable equipment.\nExperience with Fadal, Heian, Onsrud, Thermwood, Zimmerman, or comparable machine and control platforms.\nExperience developing, tuning, or validating post processors and automated probing routines, including Renishaw or equivalent systems.\nExperience with AS9100-based manufacturing systems, aerospace first article inspection, AS9102 documentation, process qualification, change control, and configuration management.\nExperience machining acrylic, polycarbonate, composite structures, aluminum, titanium, or other materials relevant to aerospace transparency and structural-component manufacturing.\nExperience standardizing CAM templates, tool libraries, digital work instructions, setup documentation, or knowledge-reuse systems.\nBasic scripting or automation experience, such as Python, VB, macros, or CAM customization.\nExperience supporting new machine installation, acceptance, industrialization, or transfer from an external specialist to an internal production team.\nWe’ll offer you fantastic challenges and amazing opportunities.
