The role shapes TaxSys’s value story, strengthens sales and demo enablement, supports client adoption and implementations, and helps expand the platform into new markets.

Responsibilities:

• 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
• Track how teams use TaxSys content and training, how effective they are and how marketing campaigns perform. Use the results to decide what to improve and where to focus

Requirements:

• Have 5-7+ years of product marketing experience for complex B2B software, with meaningful ownership of positioning, value and proof development, sales enablement, customer adoption, or market research
• Have marketed enterprise software to government—ideally state or local government
• Experience in tax administration, government finance, payments, systems of record, or another regulated market is especially valuable
• Have a track record of turning product capabilities, customer outcomes, and market insight into credible proof, sales stories, and enablement
• Have strong strategic writing, presentation, and executive communication skills, with the ability to influence cross-functional leaders without direct authority
• Have built adoption or client-enablement programs and, ideally, supported major implementations
• Learn complex operational domains quickly, work effectively through ambiguity, and use qualitative and quantitative evidence to make sound decisions
