What You’ll Do

We are seeking a Sr. Account-Based Manager to own Horizon3.ai's account-based marketing strategy and execution across our highest-priority target accounts. This is a hands-on, high-impact role responsible for orchestrating personalized, multi-touch programs across digital, field, direct mail, and sales channels - designed to open doors with net-new prospect accounts, accelerate pipeline velocity, engage buying groups at in-flight opportunities, and deepen penetration within key accounts.

You will report directly to the Sr. Director, Demand Generation and work in close partnership with sales, SDRs, field marketing, digital, and product marketing to ensure ABM is a coordinated motion - not a siloed program. Every account gets a plan. Every plan has a pipeline outcome. Every outcome gets measured.

This is not a campaign execution role in the traditional sense. It's an account intelligence and orchestration role that uses marketing as a precision instrument to help sales win.

ABM Strategy and Account Planning

• Own Horizon3.ai's ABM strategy across all tiers - from one-to-one programs for highest-priority enterprise accounts to one-to-few and one-to-many plays for broader target account lists.

• Partner with sales leadership and SDR leadership to define and maintain the target account list, segmented by tier, segment, intent signal, and pipeline stage.

• Develop account-level program plans for tier-one accounts - including buying group mapping, engagement gap analysis, message personalization, and coordinated channel sequencing across digital, field, direct mail, and sales.

• Build and maintain a structured ABM planning and reporting cadence with sales - ensuring account plans are live, shared, and updated as accounts progress or stall.

Program Execution and Orchestration

• Design and execute multi-touch ABM programs that meet buyers where they are - combining Influ2 contact-level advertising, ZoomInfo Co-Pilot intent targeting, Reachdesk direct mail and gifting, LinkedIn, field event invitations, and coordinated SDR outreach into cohesive account plays.

• Build tiered plays for different account scenarios: cold prospect accounts with no engagement, accounts showing intent but no active conversation, accounts with open pipeline that need acceleration, and velocity accounts approaching decision.

• Partner with field marketing to extend ABM plays into in-person experiences - CISO dinners, roundtables, bespoke Enterprise events/experiences, and executive events designed to engage specific buying group members at priority accounts.

• Coordinate with digital on paid media targeting, ensuring Influ2 and LinkedIn programs are running against the right contacts at the right accounts with the right message at each stage of the buying journey.

• Partner with product marketing to develop account-relevant proof points and personalized content - ensuring the right case study, benchmark, or use case is in front of the right persona at the right time.

Direct Mail and Gifting Programs

• Own Horizon3.ai's direct mail and gifting strategy as a precision ABM tool - not a spray-and-pray tactic.

• Build tiered gifting plays through Reachdesk or equivalent platforms, coordinated
