Aptitude’s Client Success (“CS”) Team plays a crucial role in driving successful engagement with enterprise clients in the banking, finance, and subscriptions markets. As a Senior Client Success Manager, you will lead strategic management efforts for the organization’s key clients, influencing value creation and delivery activities at a senior level.

The Senior Client Success Manager will take full commercial ownership of a portfolio of enterprise clients in North America, ensuring retention, expansion, and long-term growth.

• Own and deliver against annual revenue targets (renewals + expansion) across your client portfolio.
• Independently negotiate and close renewals and expansions, including multi-year and enterprise-wide contracts.
• Drive upsell and cross-sell across the full solution suite, identifying whitespace opportunities and expanding into parent companies, subsidiaries, and sister organisations.
• Lead C-suite level engagements, delivering compelling ROI-focused QBRs and positioning Aptitude as a growth partner.
• Build and execute strategic account expansion plans that directly tie product adoption to commercial outcomes.
• Accurately forecast pipeline and deliver ≥90% forecasting accuracy on renewals and expansions.
