• Maintain consistency of style, terminology, and structure across documentation produced for different tiers and teams.
• Support Jira-based documentation workflows, including maintaining artifact linkage between tickets and their associated governance documents.

• Manage documentation workload across multiple tiers concurrently and prioritize according to team deadlines and work cycles. Qualifications
• Active Secret clearance.
• Bachelor's degree in Technical Writing, English, Communications, or a related field; or equivalent experience.
• 4–6 years of experience as a Technical Writer, preferably supporting technical or IT service delivery documentation.
• Demonstrated ability to translate technical and functional discussion into structured written documentation without altering substantive content or decisions.
• Excellent written and verbal communication skills, with strong attention to detail and consistency.
• Ability to work independently on documentation production while deferring content authority and sign-off to the appropriate tier lead.
• Proficiency with standard documentation tools and version control practices.
• Familiarity with Jira or comparable structured ticketing/documentation workflows.
• Ability to manage documentation across multiple concurrent projects and meet gate-driven deadlines.
