The Senior Customer Success Manager will own the relationship for Tier 1 and Tier 2 accounts, serving as a subject matter expert in HCM, Payroll, and WFM. They are responsible for driving customer outcomes, managing account plans, and identifying expansion opportunities while acting as the primary customer advocate.
Reports To & Team
This role reports to the Senior Director, Customer Success, and partners closely with the two Junior CSMs covering the pooled Tier 3 book, the Renewals Specialist, and the vertical Sales Director.
What You'll Do
Own the Relationship
Serve as the named CSM for every Tier 1 and Tier 2 account in your vertical — high-touch for Tier 1 (executive sponsor pairing, quarterly Executive Business Review), structured touch for Tier 2 (regular QBR cadence, active health monitoring).
Build and keep current an account plan for every Tier 1 and Tier 2 account.
Own key-contact identification and maintenance in Salesforce for every assigned account.
Be the Customer's Advocate
Represent the customer's interest, full stop — selling and negotiating activity routes to Sales or the Renewals Specialist, not the CSM.
Capture customer sentiment systematically: CSAT and NPS after every QBR, plus a twice-yearly relationship NPS.
Escalate at-risk signals early, partnering with the Senior Director and Delivery leadership on the intervention.
Bring Deep Expertise
Serve as the subject-matter expert on HCM, Payroll, and WFM for your accounts, translating platform capability into customer outcomes.
Build and maintain real industry credibility in the vertical — relevant benchmarks, trends, and peer context you bring to every account.
Drive Growth & Referenceability
Identify and pursue expansion and upsell opportunities against identified whitespace, partnering with your vertical Sales Director and New Business Sales.
Build reference and case-study candidates from your book, feeding the reference and case-study pipeline.
Be the connective tissue between the account and both your Sales Director at Mosaic and UKG's account teams — your credibility with the customer is what earns traction with both.
