If you are excited to solve hard problems alongside talented, mission-driven people, we invite you to help us build a safer future for humanity. What Are We Looking For? We’re looking for people who are relentlessly curious and committed to continuous learning. AI is reshaping every function across our business, and we enable every team member, regardless of role or level, to build fluency in AI tools and concepts. Those who thrive here actively seek out new solutions, experiment thoughtfully, and apply what they learn to drive better, faster, smarter outcomes. As a Senior Customer Success Manager, Enterprise, you will own post-sales relationships with our most high-value customers, serving as their primary advocate and ensuring they achieve measurable outcomes with SentinelOne's platform. You will work closely with internal teams across Sales, Renewals, Support, Services, and Product to drive adoption, mitigate risk, and deliver an exceptional customer experience at the enterprise level. If you are a relationship expert with a technical orientation and a passion for making customers successful, we would love to have you on our team. What Will You Do? Primary responsibilities include: Own post-sales relationships with a portfolio of high-value enterprise customers, advocating for their success internally, establishing critical goals and onboarding plans, and driving regular executive engagement at VP and C-level. Promote product adoption and deliver ongoing tailored customer engagement — including weekly meetings, health checks, and QBRs — while proactively using customer success platforms and health indicators to identify and remove blockers to success and retention. Collaborate cross-functionally with Sales, Renewals, Support, Services, and Product teams to achieve optimal customer outcomes, and manage escalations by orchestrating internal resources to reach timely resolution. Identify and mitigate customer risk early to ensure high retention rates, and meet with senior leadership quarterly to report on portfolio health, trends, and strategic opportunities. Understand customers' challenges, advise on best practices, and manage expectations in a way that consistently results in high customer satisfaction across a diverse, enterprise-level portfolio. What Skills and Knowledge Will You Bring? Ideal candidates will have: Fluency in English, with very strong written and verbal communication skills and demonstrable experience engaging with customers from diverse cultures and backgrounds. Fluency in German, Italian, or Spanish is a strong plus, though not a hard requirement. Prior experience in a Customer Success Manager role handling enterprise accounts of 20,000 employees or more, with a proven track record of driving adoption, managing escalations, and delivering high retention outcomes. A customer-centric approach with the ability to understand complex customer challenges, manage expectations effectively, and build strong, lasting relationships at senior stakeholder level. Detail-oriented and analytical mindset, with the ability to thrive in a multitasking environment, adjust priorities on the fly, and operate as both a strong team player and a self-starter. Experience with Salesforce and customer success platforms such as Totango or Gainsight is a plus, as is previous cybersecurity industry experience or a demonstrated understanding of security concepts and terminology. Why SentinelOne? AI is redefining how the world operates and rewriting the rules of security in real time, and SentinelOne was built for this moment. From day one, we architected an AI-native platform designed to operate at machine speed, not as an add-on to legacy systems but as the foundation itself.
