Enterprise Client Success Manager — Fintech & Crypto

Fun; Singapore; On-site; SGD 120,000 - 180,000; Full time

Job summary

Fun, based in Singapore, is seeking a Client Success professional to own a named enterprise book and support mid-market clients as they move to product. You will manage renewals and expansion, ensure coverage across the enterprise book, and collaborate with engineering and product teams.

This role sits at the intersection of fintech infrastructure and customer experience. You will leverage Claude daily to draft, document recurring client questions, and create scalable documentation while

Qualifications

• 5+ years in client success or technical account management, owning named enterprise accounts at an API, infrastructure or payments company.
• Technical range to follow an integration and answer most questions yourself. You do not need to write production code
• Strong AI skills and real fluency with Claude or an equivalent — already using it to do more than you otherwise could
• Honest and forthright. You can run a difficult conversation, a renewal and a pricing discussion rather than defer any of them
• Excellent async operator across time zones, and a strong internal communicator with engineering, product and design

Responsibilities

• Own enterprise relationships. A named share of the book: standing syncs, regular reviews, escalation when something breaks, and meeting clients in person
• Be the second pair of hands. Cover the rest of the enterprise book so no client depends on one person being available
• Own renewals and expansion. Keep your accounts renewing, spot the client whose usage has outgrown their tier, and keep our CRM straight enough that nothing is a surprise
• Take mid-market, then automate it. Triage and kickoff for your share of mid-market, and build the self-serve alternative with the Client Success lead
• Use AI, and speak EPD. Claude daily for drafting, data and turning recurring client questions into documentation rather than a faster reply — and give engineering, product and design the written context they need without becoming a bottleneck
