Senior Customer Success Manager
Department: Customer Success
Employment Type: Full Time
osapiens is building the operating system for sustainable enterprise, a single AI-powered platform giving every company real-time control over regulatory obligations, climate impact, supply‑chain risks, and physical assets. The ambition is not to be one more compliance tool, but the infrastructure every general enterprise runs on to operate responsibly in a world where sustainability is no longer optional.
We reached unicorn status in January 2026 ($100M Series C from BlackRock/Temasek and Goldman Sachs), serve 2,500+ enterprise customers including Tesco, Coca‑Cola, Lidl, and Carrefour, and have delivered 10+ consecutive quarters of 100%+ ARR growth at 130%+ net revenue retention. Regulatory Compliance, Climate Intelligence, Supply Chain Transparency, and Asset Management, plus a network model that traces supply chains from origin to point of sale make the platform genuinely different. The Senior Customer Success Manager owns osapiens' most strategic customers. High‑value and high‑profile accounts that demand a senior, consultative relationship, close monitoring, and proactive engagement. After the sale, you become the customer's trusted advisor, responsible for retention, adoption, and growth across your portfolio. You coordinate internal stakeholders around the customer's success and ensure each account realizes the full value of its investment.
Act as the customer's single point of contact, orchestrating Sales, Product, Support, and Engineering into one seamless experience.
