Senior Account Strategy Manager

Key Responsibilities

Supporting Complex Opportunities & Executive Positioning

• Directly support Sales Directors on high-value, complex opportunities — helping align approach to customer priorities and transformation goals, and bringing structure to positioning, executive engagement, and deal approach.
• Help build value-led narratives and executive summaries — supporting Sales Directors with clear, outcome-focused value propositions and win themes for C-level stakeholders.
• Provide hands-on support across a portfolio of complex Enterprise and Strategic deals — spending the majority of time working directly with Sales Directors on live pursuits.
• Apply clear engagement criteria — prioritizing where direct support can have the greatest impact based on deal complexity, strategic importance, competitive pressure, AI opportunity, and wider account potential.

Supporting Complex Pursuits

• Support Sales Directors on RFPs, PoVs, and multi-partner engagements — coordinating inputs across Five9 and partners, and structuring activity across milestones and deliverables.
• Pressure-test the deal before it advances — refining the deal structure, modeling pricing options, building the business case, and shaping the negotiation plan, then presenting to senior approvers (Five9’s Delegation of Authority process) and engaging Partner Operations as needed.
• Contribute to core deal artifacts — proposals, implementation approaches, and commercial narratives — so Sales Directors can move pursuits with clarity and pace.
• Partner with Legal, Finance, and Revenue Operations in support of Sales Directors structuring, negotiating, and closing complex deals.

Cross-Functional Alignment & Repeatable Execution

• Help align Sales, Solution Consulting, Professional Services, Product, and Marketing around a shared understanding of the account and opportunity.
• Apply — and sharpen — frameworks such as SPICED, Account-Based Selling, and Path to Partnership — bringing consistent, repeatable support to complex enterprise engagements, and testing, refining, and improving those frameworks based on what actually works in the field.
• Support lifecycle alignment from pre-sale to post-sale — capturing and handing over customer priorities, value outcomes, commitments, implementation context, and future growth opportunities, so implementation, adoption, and Day 2 begin with a deliberate transition rather than re-discovery.

GTM & Collateral Support

• Support joint GTM propositions — helping develop clearer value propositions and a coherent narrative in partner-led opportunities.
• Contribute to sales collateral and reusable assets — feeding into and refining executive summaries, proposals, and other materials Sales Directors rely on.
• Turn field experience into scalable playbooks — identifying why pursuits are won or lost, translating lessons from live deals into case studies and practical field guidance, and sharing recurring insights with the wider Sales organization.

Partnership & Workload Management

• Partner with the Senior Director, Account Strategy to align day-to-day support with the broader account strategy approach.
• Balance multiple concurrent pursuits across Sales Directors and deal cycles — switching comfortably between priorities while maintaining sufficient depth to influence the strategy and outcome.
• Contribute to a network of competence — helping bring together the right stakeholders across Sales, Product, Professional Services, Partners, and Advisory teams.
