About the job

As a Senior Technical Writer, you will lead documentation efforts for software applications, IT systems, and mission-critical technologies supporting national-security missions. You'll work closely with software engineers, systems engineers, program leadership, subject-matter experts, and customer stakeholders to gather information, understand technical concepts, and produce clear, accurate, mission-ready documentation.

We're looking for an experienced technical writer who is comfortable working in a software development environment, understands technical terminology, and can independently translate complex information into documentation that is easy to understand and maintain. Programming experience is not required.

This is an opportunity to do more than document products. You'll help shape how critical technical information is communicated, understood, maintained, and ultimately used.

Gaithersburg, MD is the primary work location. The Senior Technical Writer can have a flexible, telework-friendly schedule but must be local to Gaithersburg, MD to come in throughout the week as needed.

Help establish and maintain consistent documentation standards, templates, and content-management practices across development teams.
