- 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.
- 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.

- Familiarity with Jira or comparable structured ticketing/documentation workflows.
- Ability to manage documentation across multiple concurrent projects and meet gate-driven deadlines.
