Principal Systems Engineer - Onsite

We need to output only HTML fragment, with headings

for sections: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Only include sections that have real specific content. Must not repeat job title as heading. Must not include Job ID etc. Must preserve all substantive info. Remove boilerplate: cookie/navigation/legal/EEO/equal-opportunity/scam-warning, duplicated lines, application instructions. Also remove "Learn More & Apply Now!" etc. Also remove "Please ensure the role type..." etc. Remove "As part of our commitment..." etc. Remove salary range? Actually salary is Pay section, we should include Pay if posting states it. It does: "The salary range for this role is 118,300 USD - 224,900 USD." So include Pay section with that info. Benefits: they list many benefits; include Benefits section. Schedule: they mention Onsite role; schedule maybe not explicit; they say "Onsite: This is an onsite role supporting our Sterling, VA location." That's about location, not schedule. No explicit schedule like full-time, hours. So we should not create Schedule section unless posting actually states it. It does not state schedule like "Full-time" etc. So omit Schedule. Qualifications: there are "Qualifications You Must Have:" and "Qualifications We Prefer:" plus earlier "U.S. Citizen, U.S. Person, or Immigration Status Requirements:" etc. We need to combine into Requirements and Qualifications sections? The instruction: use headings for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). So we need to map content. We have About the role: description paragraph after "Principal Systems Engineer - Onsite At RTX..." includes company description and role description. Could be About the role. Responsibilities: the bullet list under "What YOU will do:" is responsibilities. Requirements: likely the security clearance, citizenship, etc. Also "U.S. Citizen, U.S. Person, or Immigration Status Requirements:" and "Active and transferable U.S. government issued security clearance is required prior to start date." Also "U.S. citizenship is required". Also "Security Clearance Type: Secret - Current Security Clearance Status: Active and existing security clearance required on day 1". Also "Position Role Type: Onsite". Also "U.S. Citizen, U.S. Person, or Immigration Status Requirements:" maybe part of Requirements. Qualifications: the "Qualifications You Must Have:" and "Qualifications We Prefer:" plus maybe degree/experience. Skills: maybe we can extract skills like MBSE, SysML, etc. Could put under Skills. But we must not create thin sections. Prefer few substantive sections. Could combine Requirements and Qualifications? But headings are separate. We need to decide. We have substantive content for About the role, Responsibilities, Requirements (clearance, citizenship, onsite), Qualifications (experience, degree, MBSE, etc.), Skills (maybe MBSE, SysML, etc.), Benefits, Pay. We could omit Skills if we can incorporate into Qualifications. But we need to follow instruction: use headings for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). It doesn't say we must include all; we include only those with real specific content. So we can include Skills if we have specific skill list. Let's extract skills: "Experience with capture, analysis and decomposition of System requirements", "Understanding of the Product Development Lifecycle – from CONOPS to Sustainment", "Must have experience with Model-Based System Engineering (MBSE) design tools (Enterprise Architect, Cameo, or equivalent) using SysML", "Ability to work in a classified environment and obtain/maintain required security clearance", "Strong communication and collaboration skills.", "Requires on-site presence in a classified lab space." Also "Background in simulation and training system development", "Experience working in a SAFe Agile environment", "Familiarity with real-time systems, distributed simulation or virtual training environments", "Experience with hardware/software integration and lab environments", "Knowledge of DoD acquisition processes and standards". Those could be skills. We could put them under Skills as a list. Qualifications: maybe focus on education/experience: "Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 8 years prior relevant experience or an Advanced Degree in a related field and minimum 5 years of experience". Also "Active and transferable U.S. Government DoD Secret Security Clearance is required prior to start date." But that's also requirement. Might duplicate. Better: Requirements: security clearance, citizenship, onsite. Qualifications: education/experience, degree, years. Skills: technical skills list. Let's craft. We must preserve all substantive information; do not invent or summarize away detail. So we need to keep all details from the posting, but we can rephrase? The instruction: "Preserve ALL substantive information; do NOT invent or summarize away detail." Means we should not omit details, but we can reformat. Must not lose any info. So we need to include all details from the posting that are substantive. That's a lot. We need to ensure we don't drop any. Let's list all substantive info from posting: - Date Posted: 2026-09-16 (maybe metadata, can be dropped as minor metadata) - Country: United States of America - Location: US-VA-STERLING-291 ~ 22640 Davis Dr ~ DAVIS - Position Role Type: Onsite - U.S. Citizen, U.S. Person, or Immigration Status Requirements: (maybe part of requirements) - Active and transferable U.S. government issued security clearance is required prior to start date. - U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance - Security Clearance Type: Secret - Current Security Clearance Status: Active and existing security clearance required on day 1 - Principal Systems Engineer - Onsite At RTX, the world largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world’s most complex problems.

It's more marketing; but we might keep as part of About the role? The instruction: remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, and application instructions. The marketing fluff maybe not boilerplate but could be considered part of About the role. However we already have About the role from earlier description. The later paragraphs are repetitive. Might be considered duplicated lines. Safer to omit them as they are not unique substantive info beyond what we already have. The instruction: "Preserve ALL substantive information; do NOT invent or summarize away detail." If we omit those marketing paragraphs, are we losing substantive info? They are somewhat repetitive of earlier description but maybe add some nuance: "At Collins Aerospace, our Mission Systems team helps civilian, military and government customers complete their most complex missions — whatever and wherever they may be. Our customers depend on us for intelligent and secure communications, missionized systems for specialized aircraft and spacecraft and collaborative space solutions. By joining our team, you’ll have your own critical part to play in ensuring our customer succeeds today while anticipating their needs for tomorrow." That's additional info about the team and mission. Could be considered substantive. However it's somewhat generic marketing. The instruction says remove duplicated lines. This is not duplicated exactly but similar theme. Might be okay to keep as part of About the role. But we also have salary range: "The salary range for this role is 118,300 USD - 224,900 USD.
