Lead Mechanical Engineer

We need to output HTML fragment with sections only when there is real specific content. We must not repeat job title as heading. Use

for section headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. We need to include sections only if posting has real specific content. We have description: includes "Description" paragraph about Leidos, mission etc. That's generic but maybe "About the role"? Actually "Description" includes company overview, mission, etc. Could be considered "About the role"? But we need to decide. We have "Primary Responsibilities" list. So we can have

Responsibilities

with

• items. We have "Basic Qualifications" and "Preferred Qualifications". Could combine into Requirements? Or separate sections: Requirements (basic) and Qualifications (preferred). The instruction says use headings like Requirements, Qualifications, Skills, Benefits, Pay, Schedule. So we can have Requirements (basic qualifications) and Qualifications (preferred). Also maybe Skills: we could extract skills from qualifications (proficiency with 3D CAD, PLM, GD&T, etc.) but we could also put them under Requirements or Qualifications. Better to follow: Requirements = basic qualifications; Qualifications = preferred qualifications; Skills maybe not needed if covered. But we could still include Skills if there is explicit skill list. The posting includes many skill-like items: proficiency with 3D CAD tools, PLM, GD&T, engineering drawings, etc. Those could go under Skills. However we must not invent sections; we need real specific content. The posting does have skill-related statements. So we could have a Skills section. We have Pay Range: "$107,900.00 - $195,050.00". Also a note about pay range being guideline. So we can include Pay section with that range. We have Benefits: mention "Pay and benefits are fundamental... Employment benefits include competitive compensation, Health and Wellness programs, Income Protection, Paid Leave and Retirement." Also link to details. So we can include Benefits section with those items. Schedule: not mentioned. No schedule info. So we should not include Schedule heading. About the role: maybe we can include a short paragraph summarizing role from description: "Leidos’ Defense Systems is seeking a talented Mid-Level Mechanical Engineer to join its Hypersonics line of business..." etc. That is specific content about the role. So we can have About the role section. We must not include boilerplate like EEO, scam warning, navigation, etc. Remove those. We must preserve all substantive information; do not invent or summarize away detail. So we need to keep all details from responsibilities, qualifications, etc. Not omit any. We need to format as HTML fragment only, no /, no markdown fences. We'll produce:

  About the role

  Leidos’ Defense Systems is seeking a talented Mid-Level Mechanical Engineer to join its Hypersonics line of business. With offices across the United States engaging in the defense, space, cyber and commercial fields, Leidos provides responsive, cost-effective engineering, scientific and IT solutions. The selected candidate will support hypersonic development programs, contributing to advanced weapon system development efforts that are critical to maintaining U.S. technological superiority in this rapidly evolving domain.

  Then Responsibilities: list each responsibility as
• . Need to preserve all responsibilities exactly as written. Let's extract from "Primary Responsibilities" block: - Lead and coordinate mechanical engineering activities for a key hypersonic vehicle subassembly. - Coordinate and contribute to the design and development of mechanical components and assemblies for advanced hypersonic missile systems. - Communicate technical and program requirements to external partners and suppliers, ensuring requirements are clearly understood and incorporated into their designs. - Serve as the primary technical interface for external design partners, coordinating design activities, interfaces, deliverables, technical decisions, and issue resolution. - Develop and maintain engineering plans and schedules, track progress against commitments, and communicate status, risks, and recovery plans to program leadership. - Own and coordinate mechanical interfaces between the assigned subassembly and adjacent subsystems, ensuring interface requirements are defined, documented, communicated, and verified. - Coordinate the development, review, and release of Technical Data Package (TDP) artifacts, including drawings, bills of materials (BOMs), and specifications. - Develop mechanical designs with consideration for functionality, manufacturability, assembly, inspection, and producibility. - Apply Geometric Dimensioning and Tolerancing (GD&T) principles in accordance with ASME Y14.5 and applicable engineering drawing standards. - Perform tolerance analyses and engineering calculations to support design decisions and verify component and assembly requirements. - Plan, facilitate, and participate in design reviews, peer reviews, drawing reviews, and other technical meetings throughout the product development lifecycle. - Support prototype fabrication, assembly, integration, and testing activities by troubleshooting mechanical issues, coordinating issue resolution, and implementing engineering solutions. - Evaluate engineering changes for impacts to design, interfaces, manufacturing, cost, schedule, and downstream hardware. - Collaborate with multidisciplinary teams, including structural, thermal, systems, manufacturing, quality, and test engineering, to develop and mature mechanical designs. - Perform work in both classified and unclassified environments as required. We need to keep each as separate
• . Then Requirements (basic qualifications): list each bullet. Basic Qualifications block: - Active DoD Secret security clearance. - Bachelor’s degree in engineering from an ABET-accredited institution with 8+ years of relevant experience or Master’s degree with 6+ years of relevant experience or high school diploma with 12+ years of relevant experience. - Proficiency with 3D CAD tools such as Creo, CATIA, AutoCAD, SolidWorks, or similar software. - Experience working within Product Lifecycle Management (PLM) environments. - Working knowledge of Geometric Dimensioning and Tolerancing (GD&T) in accordance with ASME Y14.5 and basic tolerance stack-up analysis. - Understanding of engineering drawings, specifications, and configuration management processes. - Strong understanding of mechanical design principles, including statics, mechanics of materials, materials science, and manufacturing processes. - Demonstrated ability to facilitate technical meetings and drive technical decisions with internal and external stakeholders. - Experience interacting directly with customers, suppliers, or external engineering partners and representing an engineering organization in technical discussions. - Demonstrated understanding of cost, schedule, and programmatic impacts associated with engineering decisions and deliverables. - Ability to communicate technical information effectively through written documentation, drawings, presentations, and verbal communication. - Strong attention to detail, analytical thinking, problem-solving, communication, and collaboration skills. - Self-starter with a demonstrated ability to work independently and in team environments, as well as ability to provide clarification and instruction to others. - Proficiency with Microsoft Office applications (Word, Excel, PowerPoint). We need to keep each as
• . Then Qualifications (preferred qualifications): list each bullet. Preferred Qualifications block: - Experience supporting DoD programs involving missile systems, reentry vehicles, hypersonic systems, or other advanced aerospace technologies. - Experience leading a mechanical assembly, subsystem, work package, or similar engineering scope through design, development, integration, and/or production. - Experience coordinating engineering activities with suppliers, subcontractors, or external design partners. - Experience supporting rapid development, prototyping, or fast-paced engineering programs. - Experience creating 3D models and engineering drawings using PTC Creo and managing data within Windchill. - Familiarity with aerospace materials and manufacturing processes, including machining, composites, additive manufacturing, welding, bonding, and mechanical fastening. - Hands-on experience supporting hardware fabrication, assembly, integration, or testing. - Familiarity with structural and/or thermal analysis as it relates to mechanical design. We'll put each as
• . Then Skills: Could we extract skill statements? Many of the qualifications already cover skills. But we could still create a Skills section summarizing e.g., "Proficiency with 3D CAD tools (Creo, CATIA, AutoCAD, SolidWorks)", "PLM experience", "GD&T per ASME Y14.5", "Engineering drawings and specifications", "Mechanical design principles", "Technical communication", "MS Office". However that would be duplicative. The instruction says prefer a few substantive sections over many thin ones. So maybe we omit Skills section and let Requirements and Qualifications cover skills. But we need to include Skills heading only if there is real specific content for it. The posting does not have a separate "Skills" heading; but we could infer skill content. However to be safe, we could omit Skills section. Benefits: we have "Pay and benefits are fundamental... Employment benefits include competitive compensation, Health and Wellness programs, Income Protection, Paid Leave and Retirement." Also link. We'll create Benefits section with
  • items: competitive compensation, Health and Wellness programs, Income Protection, Paid Leave, Retirement. Also maybe note that more details at website but we should not include navigation/link? The instruction says remove application instructions, but linking to more details maybe okay? It's not boilerplate; it's a reference. Might be okay to keep as a sentence. But we should avoid including just a link; we can include a sentence: "More details are available at www.leidos.com/careers/pay-benefits." That's not boilerplate; it's specific. We'll keep as

    . Pay: we have Pay Range $107,900.00 - $195,050.00 and note that it's a guideline. We'll include that as

    with the range and note. Schedule: none. Now we need to ensure we don't repeat job title as heading. We didn't. We must not include any metadata like Job ID, requisition numbers. There's "Original Posting September 18, 2026" etc. That's metadata; we should drop it. Also "For U.S. Positions: While subject to change..." that's about posting duration; we can drop as minor metadata. Also "Pay And Benefits" heading we already used Benefits; but we need to not duplicate heading. We'll just use Benefits section. We must not include EEO, scam warning, commitment to non-discrimination, etc. Remove those. Now produce HTML fragment. Let's craft:
