Senior Information System Security Officer (ISSO) - El Segundo, CA (Sponsor Clearance)

We need to output only HTML fragment, no html/body tags, no markdown fences. Use

for section headings: About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule. Include sections only if posting has real specific content. Remove boilerplate, navigation, legal, EEO, etc. Preserve all substantive info. We need to parse the posting. Key info: - Date posted, location, etc: we can drop metadata (date posted, location, etc) as minor metadata, maybe put in a short

or drop. 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

with location and date maybe, but not required. Probably better to drop. - Role: Senior Information Systems Security Officer (ISSO), onsite. - About the role: The paragraph about RTX, mission, etc. Could be "About the role" or "About the company". We'll use "About the role" heading. - Responsibilities: bullet list from "What You Will Do": Assessing and monitoring system compliance, auditing, security plan development and delivering information systems security education and awareness. Investigating information system security violations and help prepare reports specifying corrective and preventative actions. Reviewing and approving (within authority) configuration management requests. Conducting technical and administrative assessments. Integrating new cybersecurity processes, procedures, and tools. Support the creation, review and update of cybersecurity documentation and other technical writing. Also note: "Important note: Within six months of hire date, you must obtain and maintain a Security professional certification commensurate with IAM Level I certification (Security+ or other), if you do not already have this certification." That's a requirement, maybe under Requirements or Qualifications. - Requirements: The posting includes "U.S. Citizen, U.S. Person, or Immigration Status 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: DoD Clearance: Secret Security Clearance Status: Ability to obtain INTERIM U.S. government issued security clearance is required prior to start date". Also "Important note: Within six months of hire date, you must obtain and maintain a Security professional certification commensurate with IAM Level I certification (Security+ or other), if you do not already have this certification." Also "The ability to obtain and maintain a U.S. government issued security clearance PRIOR TO START is required. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance" repeated. Thus Requirements section: U.S. citizenship required; active and transferable U.S. government issued security clearance required prior to start; ability to obtain interim clearance required; must obtain/maintain Security+ or equivalent within six months. - Qualifications: "You Must Have" bullet list: Typically requires a University Degree or equivalent experience and minimum 5 years prior relevant experience, or an Advanced Degree in a related field and minimum 3 years’ experience. Then list of relevant experience considered: Cybersecurity, systems security or hardening; Information Technology; Compliance-based auditing using RMF, DCSA Assessment and Authorization Process Manual (DAAPM), Joint SAP Implementation Guide (JSIG), National Industrial Security Program Operating Manual (NISPOM), and/or non-defense regulations such as FAA, Payment Card Industry (PCI), ISO 9001 Quality Management standards, or HIPPA; Experience working with and/or supporting computer technologies (such as: databases, operating systems, computer network hardware, software programs, hardware troubleshooting or electronics); Physical security/security, policework/criminal justice, investigations, or Border Patrol; Project or program management, office management, senior administration, or account management. Also "Qualifications We Prefer": bullet list: Experience working in DoD classified operating and/or laboratory environments. Experience with various information system security tools that address vulnerability analysis and mitigation. These may include Splunk, Forcepoint, Ivanti, Tenable, ACAS, HBSS, etc. Familiarity with implementation of Government directives and policies derived from NIST, CNSSI, DoD, or other Government Regulatory compliance standards within a professional industry. Experience in the execution of the Assessment & Authorization processes, as defined within the Risk Managed Framework (RMF). Experience providing technical security consultation for complex, cross-domain, heterogeneous classified networked environments in collaboration with internal/external Customers, Information Technology (IT). Familiarity with large multi-facility networks including various complex components, including Windows and Linux environments. Experience interpreting, implementing, and assessing DISA STIGs. Familiarity with the execution and management of cyber incident response; preservation, containment, and eradication. Thus we can have Qualifications section with two sub-sections? But we only have headings: Qualifications, Skills, Benefits, Pay, Schedule. We could put "Qualifications" for mandatory qualifications, and "Skills" for preferred qualifications or specific skills. Or we could combine. We need to avoid filler sections like Benefits if not specific. The posting includes "What We Offer": values, relocation non-eligible, 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 short-term and/or long-term incentive compensation programs. That's substantive benefits. So we should include Benefits section. Pay: The posting includes salary range: 95,500 USD - 181,700 USD. So we include Pay section. Schedule: Not explicitly mentioned besides "Onsite". Could infer schedule is full-time? Not given. So we should not create Schedule section unless posting states it. It does not state schedule specifics, so omit. Skills: Could include technical skills: experience with Splunk, Forcepoint, Ivanti, Tenable, ACAS, HBSS, etc; familiarity with NIST, CNSSI, DoD; RMF; DISA STIGs; Windows/Linux; cyber incident response; etc. That's more like qualifications/skills. We'll put those under Skills. We need to ensure we don't repeat job title as heading. Already not. We need to output only HTML fragment, using

for section headings,

• for lists,

  for prose. We need to preserve all substantive information, not invent or summarize away detail. So we need to include all details from the posting, but we can condense into lists but must keep the info. Let's structure:

  maybe a short metadata: location and date? Could drop. But we can include a short

  with location and date posted as minor metadata. It's allowed to fold minor metadata into a short

  . We'll include:
