(boilerplate, remove) We need to include sections only if there is real specific content. Potential sections: - About the role (maybe the initial job description paragraph) - Responsibilities (maybe the list of duties? The posting includes many responsibilities/experience required; we could treat as Responsibilities) - Requirements / Qualifications (clearance, citizenship, experience, etc.) - Skills (list of technical skills) - Benefits (the WHAT YOU’LL NEED TO SUCCEED and Total Rewards) - Pay (salary range) - Schedule (weekly hours, travel, telecommuting) We must not include sections with filler like "commensurate with experience". The salary range is specific, so Pay section is valid. Schedule: we have Scheduled Weekly Hours: 40, Travel Required: Less than 10%, Telecommuting Options: Onsite. That's specific enough. Benefits: we have WHAT YOU’LL NEED TO SUCCEED list and Total Rewards description. That's substantive. Skills: we have a long list of required expertise; we can put as

• . Responsibilities: maybe we can treat the duties as responsibilities. The posting includes many experience items; we could treat them as responsibilities. However we also have Skills section; we might combine. But we need to avoid duplication. The instruction: Use
  • for any list of duties/requirements/benefits. So we can have separate sections for Responsibilities (duties), Requirements (qualifications/clearance/experience/citizenship), Skills (technical skills). Benefits (list). Pay (maybe just a

    with salary range). Schedule (maybe a

    with hours/travel/telecommute). We must not repeat job title as heading. So no heading for Core Java Software Engineer. We must not include Job ID/requisition numbers. We must remove boilerplate: cookie/navigation/legal/EEO/equal-opportunity/scam-warning, duplicated lines, application instructions. Also remove Identity Verification Process, About Our Work, Equal Opportunity Employer. We must preserve all substantive information. So we need to include clearance, citizenship, experience, location, desired skills, etc. Let's extract substantive content: - Clearance: Must Currently Possess: Top Secret SCI + Polygraph - Clearance Must Be Able To Obtain: None (maybe not needed) - Public Trust/Other Required: None (maybe not needed) - Job Family: Software Engineering (maybe not needed as heading) - Skills: list (Apache Tomcat, JDBC, Java Web Development) but also later extensive list. - Certifications: None (skip) - Experience: 10+ years of related experience - US Citizenship Required: Yes - Job Description paragraph (About the role) - Detailed technical expertise list (responsibilities/skills) - Desired skills: Some experience integrating Python into web applications; Some experience Writing Confluence plugins; Familiar w/ Windows Active Directory Certificate Services (AD CS) – for issuing and managing key infrastructure (PKI) certificates - Location: Chantilly, VA (On Customer Site) - WHAT YOU’LL NEED TO SUCCEED: list of benefits (401K with company match, Comprehensive health and wellness packages, Internal mobility team..., Professional growth opportunities..., Cutting-edge technology..., Rest and recharge with paid vacation and holidays) - Salary range: $158,855 - $214,921 - Scheduled Weekly Hours: 40 - Travel Required: Less than 10% - Telecommuting Options: Onsite Work Location: USA VA Chantilly Additional Work Locations: (maybe blank) - Total Rewards At GDIT: benefits description (medical plans, dental, vision, 401k, flex work weeks, paid time off, disability, life, etc.) We need to avoid duplication: The WHAT YOU’LL NEED TO SUCCEED and Total Rewards overlap; we can combine into Benefits section. We must not include sections with filler like "not specified". All sections we include have specific content. Now produce HTML. Structure:
