• Develop and execute a comprehensive territory plan that identifies priority accounts, buying centers, funding vehicles (e.g., O&M, RDT&E, SBIR/STTR), and competitive displacement opportunities.
• Manage the full sales cycle from prospecting through negotiation and close, including large, complex, multi-year enterprise software agreements.
• Identify, qualify, and advance pipeline across Navy commands, program offices (NAVAIR, NAVSEA, SPAWAR/PEO C4I, NAVWAR, ONR, BUMED, etc.), and associated system integrators and prime contractors.
• Partner with the Mattermost channel team to develop Navy-focused reseller and VAR relationships that extend coverage and accelerate deal cycles.

Relationship Management & Business Development

• Represent Mattermost at Navy and defense industry events, conferences (WEST, Sea-Air-Space, AFCEA events, etc.), and government forums.
• Collaborate with the Mattermost partner ecosystem, including systems integrators, VARs, GSA Schedule holders, and Navy OCONUS partners to originate and close business.
• Develop account plans and Executive Business Reviews (EBRs) that align Mattermost capabilities to Navy mission requirements and long-term strategic priorities.

Strategy & Market Intelligence

• Track Navy IT modernization initiatives, budget cycles, and acquisition strategies to anticipate and shape opportunities ahead of the competition.
• Provide ongoing competitive intelligence and market feedback to product, marketing, and leadership teams to inform Mattermosts federal go-to-market strategy.
• Maintain accurate, up-to-date opportunity and account data in Salesforce and contribute to accurate forecast cadences.
• Influence product roadmap by surfacing Navy-specific requirements around compliance (CMMC, STIG, IL4/IL5/IL6), integrations (NIPR/SIPR/JWICS), and deployment models.
