Senior Customer Success Manager

WHO ARE WE ?

DataOne designs, develops, and operates sustainable AI Factories by combining energy, infrastructure, and artificial intelligence at industrial scale. We operate large-scale digital and energy infrastructures internationally, delivering concrete projects measured in hundreds of megawatts, designed for long-term operational performance. At DataOne, we are builders and operators. We prioritize real-world execution, operational excellence, and measurable impact over theoretical promises.

YOUR ROLE

As the Senior Customer Success Manager, you are the "face of DataOne" in the United States. You serve as the primary strategic and technical point of contact for our major American clients (Hyperscalers, AI Labs, and Enterprise). Your mission is to ensure that our industrial AI infrastructures perfectly meet our clients' operational requirements. You bridge the gap between our clients' high-level business goals and our technical operations, ensuring long-term satisfaction, retention, and account growth.

KEY RESPONSIBILITIES

• Strategic Partnership: Act as the trusted advisor for US-based clients, understanding their long-term AI strategy and aligning DataOne’s infrastructure roadmap with their needs.
• Onboarding & Delivery Oversight: Supervise the transition from construction/deployment to operational phase, ensuring that technical specifications meet client expectations.
• Technical Advocacy: Translate complex technical challenges (power density, cooling efficiency, latency) into business-oriented updates for client leadership.
• Operational Excellence: Conduct Quarterly Business Reviews (QBRs) focusing on performance KPIs, sustainability metrics, and SLA adherence.
• Incident Management Lead: Serve as the executive point of escalation during critical infrastructure events, coordinating communication between our technical teams and the client.
• Voice of the Customer: Funnel US market requirements and client feedback back to our Engineering and Product teams to drive continuous improvement.
• Account Growth: Identify opportunities for capacity expansion or additional services within existing accounts.

• Executive Presence: Ability to command respect and build relationships at the C-Suite level while remaining "hands-on" with technical teams on-site.
• Problem Solving: A track record of managing complex, high-stakes crises with a calm, data-driven, and result-oriented approach.
• Communication: Exceptional storytelling and presentation skills; ability to make technical complexity simple and compelling.
• Mindset: Proactive, "force de proposition," and comfortable working in a fast-paced, international matrix environment.
• Languages: Full professional proficiency in English; French is a plus to facilitate coordination with Group Headquarters.
