Summary
At OneStream, we are redefining the future of finance with the goal of becoming the Operating System for Modern Finance. Our unified, cloud‑based Corporate Performance Management (CPM) platform enables organizations to streamline processes, make data‑driven decisions, and achieve operational excellence.
As a Customer Success Manager (CSM), you will play a critical role in ensuring customers achieve measurable outcomes and become long‑term, referenceable partners. You will manage a portfolio of customers across their full lifecycle—from onboarding and adoption through retention and growth—helping them realize maximum value from their OneStream investment.
In this role, the CSM will act as the primary advocate for your customers, understanding their unique business objectives and helping them realize maximum value from their OneStream investment. You will build deep relationships with key stakeholders, proactively address their needs, and deliver tailored solutions to drive customer satisfaction and success. The CSM will collaborate with the sales team to identify upselling and cross-selling opportunities, helping customers unlock the full value of OneStream’s capabilities. By fostering trust and delivering results, you’ll drive customer adoption and support their long-term goals. This role requires a customer-centric mindset, strong communication and problem-solving skills, and a proven ability to manage complex customer relationships. Prior experience in Customer Success is essential.
This role will manage a portfolio of approximately 30–35 mainly enterprise accounts, with a combined ARR of $5M–$15M.
The successful candidate will be based in the Ontario province, ideally Toronto as regional proximity is critical for building strong executive‑level relationships through in‑person engagement, providing timely on‑site support during customer escalations, maintaining close alignment with Regional Sales leadership, and gaining valuable insight into the local enterprise market. This proximity also helps minimise travel, enabling sustained focus on delivering strategic customer outcomes. Professional fluency in English is required, with French language capability considered highly desirable.
