Owns customer success, retention, and expansion for strategic channel partner portfolios and end customers. Leads governance, executive business reviews, escalations, account planning, and cross-functional service delivery across cloud, security, digital, and managed services. Interprets FinOps and CSP insights for stakeholders, identifies growth opportunities, and influences services pipeline. Requires strong customer leadership, business judgment, cloud financial management knowledge, and experience in managed services and partner models.
The Customer Success Manager, Channel Partner Portfolio is a senior individual contributor responsible for the strategic success, retention and expansion of Blue Mantis's most complex channel partner relationships, with an initial focus on a key national channel partner and the private equity–backed portfolio companies it serves. The role provides executive-level customer leadership, establishes scalable engagement and governance practices, and orchestrates cross-functional resources across Cloud, Security, Digital and Managed Services to drive measurable customer and commercial outcomes.
This role sits at the center of a three-way relationship between Blue Mantis, our channel partners, and their end customers. Some customers purchase cloud through our CSP program, while others contract directly and are supported through partner-led programs. Across both groups, the CSM’s mandate is the same: be a trusted and consistent presence, understand each customer’s business priorities, and widen Blue Mantis’s services footprint across Cloud, Security, Digital, and Managed Services.
The role is a hybrid of a Customer Success Manager and a Cloud Services Account Manager (CSAM). The Blue Mantis CSAM team continues to deliver FinOps analysis and recommendations, while the CSM understands cloud financial management, CSP billing, and FinOps readouts well enough to lead monthly business reviews with confidence, interpret the findings for business stakeholders, and connect them to opportunities for additional value. The CSM is a generalist rather than a subject matter expert, bringing in the right Blue Mantis specialists as each customer’s needs emerge.
The CSM is sales-adjacent, listening for opportunities in every interaction and acting as a feedback loop to the Sales and Pre-Sales teams. Success is measured through Net Promoter Score (NPS), Net Retention, the number of partner customers actively engaged, services pipeline sourced or influenced, and growth in Blue Mantis services beyond CSP.
