CNC Programming Engineer

for sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections that have real specific content. The posting includes location profile, job summary, primary responsibilities, required qualifications, preferred qualifications, key competencies, what success looks like, working environment. No explicit Benefits, Pay, Schedule. So we should not include those sections. We need sections like About the role (maybe location profile + job summary?), Responsibilities (primary responsibilities), Requirements (maybe required qualifications?), Qualifications (maybe preferred qualifications?), Skills (key competencies?), maybe we can combine. But we must follow instruction: use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we can choose which of those headings to include based on content. We have content for About the role: location profile and job summary. That's substantive. Responsibilities: primary responsibilities list. Requirements: maybe required qualifications. Qualifications: maybe preferred qualifications. Skills: key competencies. We should not include Benefits, Pay, Schedule. We must preserve all substantive information, not invent. Use

• for any list of duties/requirements/benefits, and

  for prose. We need to avoid repeating job title as heading. Not needed. We need to output only HTML fragment, no /, no markdown fences. Let's structure:

  About the role

  Location profile paragraph + job summary paragraph(s). Could combine into one

  or multiple

  . Probably separate paragraphs for readability. Then

  Responsibilities

  • ... each responsibility as list item. Then

    Requirements

    • ... required qualifications items. Then

      Qualifications

      • ... preferred qualifications items. Then

        Skills

        • ... key competencies items. We must ensure we don't include filler like "commensurate with experience". Not present. We need to preserve all substantive information: location profile details, job summary, responsibilities list, required qualifications list, preferred qualifications list, key competencies list, what success looks like, working environment. The "What Success Looks Like" and "Working Environment" are not covered by the prescribed headings; we could incorporate them into About the role or maybe as separate sections but headings limited to given list. The instruction: "Use

          for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule)." It says e.g., implying those are examples, but we should likely only use those headings. It also says "include a section ONLY when the posting has real, specific content for it". So we could add other sections if we want, but better to stick to those. However we risk omitting "What Success Looks Like" and "Working Environment". Could we incorporate them into About the role or Responsibilities? Probably we can add a paragraph under About the role covering job summary and maybe success looks like and working environment. But we need to preserve all substantive information; we can include them as paragraphs within About the role. Thus About the role will contain location profile, job summary, what success looks like, working environment. Let's extract location profile text: "Location Profile: Aerospace Dynamics International, Inc. (ADI) manufactures machined parts and assemblies for the commercial and military aerospace industries. It offers structural components, caps, panels, bulkheads, fittings, longerons, spars, chords, wing ribs, thrust reversers, structural machine parts, manufacturing tooling and stretch form blocks. ADI was acquired by PCC in April 2014. The company has received significant capital investments since the acquisition and has a highly positive growth trajectory ahead. Comprising seven facilities on its campus in Valencia, CA, ADI has over 240 full-time employees on staff." Job Summary: "We are seeking a skilled and hands-on CNC Programming Engineer to develop, optimize, and support CNC machining processes for large, complex aerospace structural components. This position is responsible for developing, proving, optimizing, and maintaining CNC manufacturing processes for large-scale aerostructure components produced on multi-axis, multi-spindle, open-bed gantry machining centers. This position will bridge engineering and manufacturing by translating engineering designs into safe, repeatable, and efficient machining processes. The CNC Programming Engineer will be responsible for CNC program development, CAM programming, tooling and workholding selection, machining strategy, process documentation, first-article/prove-out support, and continuous improvement of existing manufacturing processes. The ideal candidate combines advanced CNC programming expertise with a strong understanding of the unique challenges associated with large aerospace structures, including long machining cycles, multiple-spindle operations, large work envelopes, thin-wall structures, part movement, material removal strategy, tolerance management, and the machining of large monolithic components. This is a hands-on engineering position requiring close collaboration with machinists, manufacturing engineering, quality, tooling, maintenance, and design engineering." What Success Looks Like: "A successful CNC Programming Engineer will: Deliver production-ready CNC programs and processes that are safe, capable, and repeatable.Reduce programming and machining lead times for new components.Improve cycle times and machine utilization without compromising quality.Reduce tooling failures, scrap, rework, and manufacturing variability.Improve the quality and consistency of CNC setup and process documentation.Become a trusted technical resource for CNC machining across Engineering and Operations." Working Environment: "This position requires regular interaction with CNC equipment and manufacturing personnel in a shop-floor environment. The employee will routinely divide time between engineering/programming activities and hands-on manufacturing support." We can combine these into About the role. Now Responsibilities list: from "Primary Responsibilities" bullet list. Let's extract each bullet: - Develop and maintain CNC programs for production of large structure aerospace components. - Create CAM programs, toolpaths, setup documentation, and supporting manufacturing instructions from engineering drawings and 3D CAD models. - Develop robust machining processes for large aluminum and other aerospace structural components, including monolithic structures, frames, bulkheads, spars, ribs, skins, panels, and similar aerostructure components. - Determine optimum machining strategies, cutting tools, speeds and feeds, workholding methods, and operation sequences. - Evaluate datum strategies, machining sequence, part orientation, intermediate inspection requirements, and material condition when developing manufacturing processes. - Support CNC program prove-outs and first-piece machining directly on the manufacturing floor. - Troubleshoot machining issues related to tooling, toolpaths, workholding, part geometry, machine capability, surface finish, dimensional accuracy, and cycle time. - Optimize existing CNC programs to improve cycle time, tool life, process capability, quality, and overall manufacturing efficiency. - Design or support the development of machining fixtures, workholding, soft jaws, and other manufacturing aids. - Identify opportunities to reduce setups, machining operations, tooling costs, scrap, and operator intervention. - Develop and maintain standardized setup sheets, tooling lists, CNC documentation, and revision-controlled manufacturing processes. - Work closely with machinists during new-product introduction, process development, and production troubleshooting. - Collaborate with Quality Engineering to resolve dimensional and process-related issues. - Support root-cause investigations and corrective actions associated with machining processes. - Evaluate new cutting tools, machining technologies, equipment, and manufacturing methods. - Establish machining best practices and help standardize CNC programming methods across the manufacturing organization. - Provide technical mentoring and support to CNC machinists and other manufacturing personnel. - Ensure machining processes comply with applicable safety, quality, and engineering requirements.

Now we need to output HTML. We'll wrap each section in

          and then content. For About the role: we can have multiple

          paragraphs. Let's craft:
