About The Position

Experience marketing enterprise software to government—ideally state or local government.
A track record of turning product capabilities, customer outcomes, and market insight into credible proof, sales stories, and enablement.
Strong strategic writing, presentation, and executive communication skills, with the ability to influence cross-functional leaders without direct authority.
Experience building adoption or client-enablement programs and, ideally, supported major implementations.

Experience in tax administration, government finance, payments, systems of record, or another regulated market is especially valuable.
Comfortable with up to 10% travel for occasional team gatherings, conferences, company meetings, and select client or project visits.

Own the TaxSys value story by identifying, validating, and sharing ROI, outcomes, benchmarks, and other proof points.
Develop and refine positioning, messaging, value propositions, and core collateral that translate a mature platform into clear, evidence-based market stories.
Strengthen sales and demo enablement, including the demo narrative, presentations, discovery guidance, objection handling, and pursuit support.
Partner with Product and Client Success on client enablement and adoption programs, including business reviews, webinars, guides, and communications for high-value capabilities.
Support major, multi-year implementations with clear client communications, milestone materials, and enablement content.
Support new-market and partnership efforts through competitive, persona, RFP support, and market intelligence.
Partner with Content & Customer Marketing to develop case studies, reference stories, and other customer proof.
