We need to output HTML fragment with sections for headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections that have real specific content. We must not repeat job title as heading. No Job ID etc. Remove boilerplate: cookie/navigation/legal/EEO/equal-opportunity/scam-warning, duplicated lines, application instructions. We need to preserve all substantive info.

Privacy Policy and Terms: Click on this link to read the Policy and Terms We need to extract sections: - About the role: maybe the introductory paragraph after "Are you ready..."? Actually "What You Will Do" is responsibilities. "What You Will Learn" could be learning outcomes maybe part of responsibilities or separate? Could be "About the role" summarizing the role description. Let's decide. We have: - Intro: "Are you ready to explore the world of aerospace and defense? Do you want to learn from and collaborate with some of the greatest minds in the industry? At RTX, our internships, co-ops and full-time careers provide an exceptional foundation to work on complex problems, advance your skills and create a safer, more connected world. Discover opportunities to make a difference at RTX." That's about the role/company. - Responsibilities: "What You Will Do As a Mechanical Engineer Intern at Collins Aerospace Strategic Defense Solutions, you will participate in the design, development, and test of electronic equipment and integration kits for communication systems on military aircraft and transportable platforms. You will learn to work closely with fellow Mechanical Engineers as well as Systems, Electrical, and Manufacturing Engineering staff to ensure defined requirements are consistently met in all phases of a product’s lifecycle. With technical supervision, apply research to the planning, design, development, and testing of mechanical and/or electromechanical systems. Work with engineers and designers to produce models for components, parts, subassemblies, and assemblies. With technical oversight, execute tests for systems, subsystems, and components. Analyze test results in relation to design or rated specifications and test objectives. Communicate effectively in a cross-functional team." - What You Will Learn: "Collaboration in a multi-disciplinary team to create successful designs. How to follow appropriate design, safety, and qualification standards in development programs. Documentation of development, analysis, and test data. Processes associated with the various phases of the product development cycle." Could be part of responsibilities or separate "Learning Outcomes". But we have no specific heading for learning; we could include under Responsibilities or maybe under Skills? Probably better to include under Responsibilities as bullet points. - Requirements: security clearance, US citizenship, active existing clearance required after day 1. Also maybe "U.S. Citizen, U.S. Person, or Immigration Status Requirements:" line. So we have that. - Qualifications: "You Must Have" and "Qualifications We Prefer". Must be pursuing Bachelor's or Advanced degree in Mechanical Engineering, Aerospace Engineering or related STEM major and actively enrolled through completion. Experience may be obtained through on-the-job experience, research, coursework, or projects. Preferred: Experience with SolidWorks or similar 3D CAD software (Creo, NX, and/or Catia). Experience with ANSYS or ABAQUS (note there is a typo: "ABAQUSA" but we keep as is). Minimum of 60 hours of credit by start. Familiarity with Microsoft Office (Excel, PowerPoint, and/or Word). Prior RTX internship, co-op, or work experience. - Skills: maybe we can extract from preferred qualifications as skills: SolidWorks, Creo, NX, Catia, ANSYS, ABAQUS, Microsoft Office. Also maybe communication, teamwork. But we need to decide if we include Skills section. The posting does not have a explicit "Skills" heading, but we can create a Skills section if we have specific content. The rule: include a section ONLY when the posting has real, specific content for it — never emit a heading followed by filler/placeholder text. So we can create Skills if we have specific skills listed. We have those from qualifications we prefer. So we can include Skills. - Benefits: The posting includes "What We Offer" with values, relocation eligibility, benefits list: medical, dental, vision, life insurance, short-term disability, long-term disability, 401(k) match, flexible spending accounts, flexible work schedules, employee assistance program, Employee Scholar Program, parental leave, paid time off, holidays. Also mention incentive compensation programs. So we have benefits. - Pay: Salary range: 37,000 USD - 82,000 USD. - Schedule: Not explicitly mentioned besides "Onsite" role type. There's mention of flexible work schedules as a benefit, but not schedule specifics. The posting does not give schedule like full-time, part-time, hours. So we should not create Schedule section because no specific schedule info. Also we have relocation eligibility mentioned but not details. We should not include boilerplate like EEO, privacy policy, application window, etc. We need to output only HTML fragment, using

for section headings,

• for lists,

  for prose. We need to avoid repeating job title as heading. No job title appears in heading. We need to preserve all substantive information; do not invent or summarize away detail. We need to remove duplicated lines. Let's craft sections:
