Description du poste

• You own the commercial relationship for Siena’s highest-value brands: renewals, expansion, executive trust, and knowing your accounts better than anyone. A deployment strategist owns product outcomes for the same accounts — together you’re the Siena pod
• You hold your accounts to specific, measurable commercial outcomes: net dollar retention, expansion, and the strength of the executive relationship. You own our Growth and Strategic segment accounts - not the full customer book - and work at the intersection of customer, sales, and your deployment strategist. You’ll lead commercial reviews, executive account mapping, and account planning, and run in-person workshops, account visits, and QBRs with your accounts
• You are accountable for:
• Net dollar retention (NDR) of your book
• Expansion quota attainment
• Executive relationship health across your accounts
• Own a portfolio of Growth and Strategic accounts from post-onboarding through long-term growth
• Build a concrete account plan with each customer: the commercial, operational, and CX metrics you’re moving, and the timeline for moving them
• Monitor account health, and when performance slips, bring in the deployment strategist — you own the customer communication and accountability while they execute the fix
• Hold customers and internal teams accountable when progress stalls
• Track and communicate impact clearly using data, not anecdotes
• Maintain a living stakeholder map for every account: who champions Siena, who’s skeptical, who signs, and what changes when their org changes. Act on org changes before they become renewal risk
• Build durable relationships with executive decision-makers, not only day-to-day contacts. Own the executive cadence for your book so leadership sees Siena’s value before the renewal conversation starts
• Own renewal negotiations and independently identify and close expansion opportunities, including navigating procurement, pricing, and contract tradeoffs
• Understand the cost, headcount, and revenue implications of CX decisions
• Engage confidently with senior stakeholders, including CX leaders and executives
• Quantify and communicate customer ROI using metrics tied to cost savings, efficiency, or revenue impact
• Develop a strong understanding of Siena’s product: how the core agents work together, the customer problems they solve, and how to position them in customer conversations
• Confidently explain product capabilities, connect them to business outcomes, and guide customers on the best strategic use cases
• Turn vague customer problems into clear problem statements and execution plans, partnering with other teams when needed
• Participate in cross-functional projects and build strong internal partnerships

Benefits

• The flexibility to work from anywhere
• Flexible working hours
• Stock options
• Unlimited PTO (minimum of 15 days off per year)
• Growth stipend
