In this role, you will be responsible for supporting semantic model development for client projects across the full model development spectrum, from initial use case development and discovery, through model drafting, validation, and implementation, to developing a governance plan for ongoing model improvement. You’ll work with cleared federal agencies to develop strategies, guide implementation, and apply agile principles to translate business needs into clear, actionable plans. As with all of our positions, we seek independent thinkers with exceptional written and oral communication skills. This position demands a deep understanding of business strategy and development, experience with knowledge & data management technology solutions, business analysis, and consulting skills.

Required Skills and Experience:

At a minimum, candidates must have 6-8 years of relevant work experience (which may include time spent earning relevant advanced degrees)

Proven experience analyzing, evaluating, and optimizing enterprise search
Ability to communicate advanced concepts to a variety of audiences in a variety of formats, from interpersonal communication to visual modes, including lightweight wireframes

Experience developing and deploying an auto-tagging initiative to support asset findability and discoverability
