Head of Customer Success

Who are we?

Finance teams need clear visibility into their cash flow, but most still rely on Excel to manually track data across multiple bank accounts. This makes it hard to see real-time cash positions, spot trends, and drive smarter financial decisions.

Nilus changes that.

We're building an AI-powered cash management platform that gives finance teams real-time cash visibility, forecasting, and reconciliation—all powered by AI, eliminating manual work and unlocking insights that help businesses grow.

Backed by top VCs like Bessemer, Felicis, BTV, and Symbol, Nilus is a fast-growing fintech startup led by a team of ex-fintech pros passionate about transforming the finance function.

What We’re Looking For:

We’re looking for a dynamic and results-driven Head of Customer Success to take our customer experience, retention, and expansion strategy to the next level. This role is for a strategic, hands-on CS leader with deep B2B software experience, ideally in fintech.

You’ll own customer retention, expansion, and advocacy, ensuring that every customer gets maximum value from Nilus. You’ll lead and scale the CS team, refine onboarding and engagement strategies, and work closely with Sales, Product, and Marketing to drive long-term customer success. If you thrive in fast-paced environments, love building high-performing teams, and have the experience to drive real impact, you belong with us!

What you’ll be doing:

Lead, manage and mentor the CS team, fostering high performance, knowledge sharing, and professional growth.
Track customer health and risks through regular business reviews, ensuring proactive customer success management.
Align CS with product strategy, providing structured feedback and selecting customers for beta testing.
Drive customer advocacy, identifying champions and references to strengthen long-term relationships.
Own expansion and upsell revenue, working with Sales and CSMs to forecast and execute growth opportunities.
Personally manage key US and EU accounts, ensuring seamless onboarding, proactive support, and continuous engagement.
Analyze customer behavior and mitigate churn, tracking trends and responding to risks early.
Leverage data and automation to optimize onboarding, engagement, and retention while informing product improvements.

Your qualifications:

5+ years of leadership experience in fintech, SaaS, or B2B software, with a proven track record of building and scaling CS teams.
Strong ability to drive retention, expansion, and upsell revenue while ensuring customer success.
Experience working with finance teams, treasury management, or cash flow solutions is a major advantage.
Hands-on leader—comfortable managing a team while personally owning high-value customer relationships.
Data-driven and tech-savvy, with experience using CS platforms, CRM tools, and analytics to improve customer engagement.
Exceptional communicator, able to engage with executives and finance leaders while influencing internal stakeholders.
Native-level English proficiency (both written and spoken).

If you are excited about this role and think you would be a great fit, we'd love to hear from you!
