Senior Account Strategy Manager

Join us in bringing joy to customer experience. Five9 is a leading provider of cloud contact center software, bringing the power of cloud innovation to customers worldwide. Living our values everyday results in our team-first culture and enables us to innovate, grow, and thrive while enjoying the journey together. We celebrate diversity and foster an inclusive environment, empowering our employees to be their authentic selves. We are looking for a Senior Account Strategy Manager to directly support Sales Directors on Five9’s most complex, opportunistic Enterprise and Strategic deals. Reporting to the Senior Director, Account Strategy, this leader will provide hands-on support on live pursuits and help carry out the frameworks and programs for deal strategy. The Senior Account Strategy Manager diagnoses where a pursuit needs intervention, challenges the existing approach when it isn’t working, strengthens the customer value narrative and helps remove barriers to progress. This role works directly alongside Sales Directors on complex, multi-stakeholder pursuits, helping build value-led narratives. In the most complex pursuits this role helps coordinate internal and partner teams and supports activity across milestones and deliverables, working in partnership with the Senior Director, Account Strategy. This also means working across Sales, Solution Consulting, Professional Services, Product, and Marketing, Account-Based Selling, and Path to Partnership, to bring consistency to how Five9 supports these engagements. The ideal candidate has supported complex, multi-stakeholder Enterprise or Strategic accounts before and is comfortable staying hands-on across many moving pieces at once.

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.
