for section headings: e.g., About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule.
We need to include sections only when posting has real specific content. We have:
- About the role: we have description paragraph about Northrop Grumman and the role. So we can put that in About the role
then
with that prose. - Responsibilities: we have "Essential Duties And Responsibilities" list. So
Responsibilities
then- each duty.
- Requirements: we have "Basic Qualifications" list. So
Requirements
then- .
- Qualifications: we have "Following Are Good To Have, But Are Not Required" list. That's like preferred qualifications. Could be Qualifications section. We'll put
- Administer, monitor, and maintain Linux-based systems in lab and development environments, including configuration, patching, and troubleshooting
- Load, customize, and harden Linux development workstations and servers to meet program security and performance requirements
- Troubleshoot and repair hardware problems, including diagnosing faulty components and coordinating repair or replacement

- Demonstrated ability to work collaboratively with engineers and technical leads on schedule driven programs
- Hold or able to obtain DoD Secret clearance
- This requisition may be filled at the Principal Software Engineer or Senior Principal Software Engineer level: Principal Software Engineer - Bachelor's degree in Computer Science or related discipline
Qualifications
then- for preferred.
- Skills: maybe we could combine but we have no explicit skills list separate; we could omit Skills if no specific content. The instruction: prefer few substantive sections over many thin ones. We could merge Skills into Qualifications or Requirements. But we have separate sections for Requirements and Qualifications (preferred). That's fine.
- Benefits: we have description of benefits: health insurance, life and disability, savings plan, company paid holidays, PTO, overtime, shift differential, discretionary bonus, annual bonuses, long term incentives for VP/Director. Also relocation assistance mentioned earlier: "RELOCATION ASSISTANCE: Relocation assistance may be available". That's a benefit. So we can include Benefits section.
- Pay: we have salary ranges: Primary Level Salary Range: $114,000 - $171,000; Secondary Level Salary Range: $142,200 - $213,400. Also note about overtime etc. So we can include Pay section.
- Schedule: no explicit schedule info. Not given. So we omit Schedule.
We must not repeat job title as heading. No Job ID etc.
We must remove boilerplate: EEO, equal opportunity, scam warning, application instructions, etc. Also remove "The application period for the job is estimated to be 20 days..." etc. Also remove "U.S. Citizenship is required..." maybe that's a requirement? It's a requirement for clearance but we already have clearance requirement: "Hold or able to obtain DoD Secret clearance". The citizenship statement is boilerplate; we can drop.
We need to preserve all substantive information. So we need to include relocation assistance mention, clearance required, travel no, etc. Those are minor metadata; we can fold into a short
maybe under About the role or a separate meta paragraph. The instruction: "do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short
or drop it." So we can include a short paragraph with metadata like "Relocation assistance may be available. Clearance required for start: No. Clearance type: None. Travel: No." But we need to decide if we keep that. It's substantive? It's minor metadata; we can include as a short p. We must not invent or summarize away detail. So we need to keep the exact salary ranges, responsibilities list, qualifications list, etc. Let's extract the exact text. From posting: Description paragraph: "At Northrop Grumman, our employees have incredible opportunities to work on revolutionary systems that impact people's lives around the world today, and for generations to come. Our pioneering and inventive spirit has enabled us to be at the forefront of many technological advancements in our nation's history - from the first flight across the Atlantic Ocean, to stealth bombers, to landing on the moon. We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they're making history. Northrop Grumman Defense Systems seeks a Software Engineer to join our diverse team, working on the Forward Area Air Defense (FAAD) portfolio of programs in Redondo Beach, CA. The selected candidate will perform system administration duties for an Army Air Defense System that includes defense against manned aircraft; rockets, artillery, and mortars; unmanned aerial systems (UAS); and cruise missile defense." That's the description. Then: "This requisition may be filled at the Principal Software Engineer or Senior Principal Software Engineer level: Principal Software Engineer - Bachelor's degree in Computer Science or related discipline (and 5 years of relevant experience in Object Oriented Languages (OOL); or 3 Years with Masters; 0 Years with PhD) or 9 years of experience in lieu of degree may be consideredSenior Principal Software Engineer - Bachelor's degree in Computer Science or related discipline (and 8 years of relevant experience in Object Oriented Languages (OOL); or 6 Years with Masters; 3 Years with PhD) or 12 years of experience in lieu of degree may be considered" We could incorporate that into Requirements or Qualifications? It's about education/experience for levels. Could be part of Requirements. We'll keep as part of Requirements maybe. Then "Essential Duties And Responsibilities" list: - Administer, monitor, and maintain Linux-based systems in lab and development environments, including configuration, patching, and troubleshooting - Load, customize, and harden Linux development workstations and servers to meet program security and performance requirements - Troubleshoot and repair hardware problems, including diagnosing faulty components and coordinating repair or replacement - Respond rapidly to high priority incidents, diagnose root causes across OS, network, and hardware layers, and restore service for critical lab environments - Collaborate closely with software developers and other engineering teams to support build environments, development workflows, and OS-related issues - Document system configurations, procedures, and changes, and contribute to maintaining accurate lab infrastructure inventories Then "Basic Qualifications" list: - Strong understanding of Linux system administration (Red Hat or similar enterprise distributions) in lab, development, or production environments - Experience installing, configuring, and troubleshooting Linux operating systems, software, servers, and associated lab hardware, including managing user accounts, groups, and file system permissions - Experience troubleshooting operating systems, networks, and hardware issues across servers and workstations - Experience performing OS level package management, building and maintaining custom RPMs, handling kernel/driver interactions, and conducting performance tuning in Linux environments - Familiarity with scripting (e.g., shell scripting) for system configuration, automation, and maintenance tasks - Demonstrated ability to work collaboratively with engineers and technical leads on schedule driven programs - Hold or able to obtain DoD Secret clearance Then "Following Are Good To Have, But Are Not Required" list: - Familiarity with virtualization platforms (e.g., VMware) and applying security patches and updates to virtualized environments - Experience supporting backup and restore solutions - Experience with vulnerability scanning and security compliance, applying OS/security patches, managing patch repositories, and maintaining antivirus tools - Experience supporting build and deployment environments, including maintaining build scripts and installation media for development environments - Current DoD Secret clearance Then salary ranges: "Primary Level Salary Range: $114,000.00 - $171,000.00 Secondary Level Salary Range: $142,200.00 - $213,400.00 The above salary range represents a general guideline; however, Northrop Grumman considers a number of factors when determining base salary offers such as the scope and responsibilities of the position and the candidate's experience, education, skills and current market conditions. Depending on the position, employees may be eligible for overtime, shift differential, and a discretionary bonus in addition to base pay. Annual bonuses are designed to reward individual contributions as well as allow employees to share in company results. Employees in Vice President or Director positions may be eligible for Long Term Incentives." Then benefits: "In addition, Northrop Grumman provides a variety of benefits including health insurance coverage, life and disability insurance, savings plan, Company paid holidays and paid time off (PTO) for vacation and/or personal business." Also earlier: "RELOCATION ASSISTANCE: Relocation assistance may be available" Also clearance and travel info: "CLEARANCE REQUIRED FOR START: No CLEARANCE TYPE: None TRAVEL: No" We need to include that metadata maybe as a short p. We must not include boilerplate like EEO, application period, etc. Now construct HTML. We'll have:
