Senior Customer Success Manager EMEA

Enterprise SaaS

Customer Data Platform & eCommerce

Location: London (On-site 4 days a week)

Type: Full-time

Overview

This platform underpins some of the most advanced customer engagement strategies globally, trusted by leading enterprise brands such as Airbnb, Spotify, NBCUniversal, JetBlue, Marks & Spencer, and ASOS. Operating at significant scale, it processes billions of transactions each year and enables real-time interactions for hundreds of millions of consumers. Backed by a global organisation of 700+ employees across North America, EMEA, and APAC, the business combines the pace of a high-growth scale-up with the backing and infrastructure of a well-established international company. Deeply embedded within clients’ technology stacks, it acts as a mission-critical layer for managing and activating customer data — powering everything from acquisition and onboarding through to retention, personalisation, and lifetime value optimisation.

The product suite combines best-in-class capabilities across real-time data collection and unification, streaming infrastructure, audience segmentation, and AI-driven personalisation and decisioning. What sets this apart is the combination of two highly complementary platforms — one focused on customer data infrastructure, the other on ecommerce monetisation and real-time relevance — creating a uniquely powerful, end-to-end solution. Still early in its combined journey, the business is experiencing strong momentum, with growing demand from enterprise customers looking to better leverage data, AI, and personalisation to unlock new revenue opportunities.

Following a recent strategic merger, we have combined best-in-class capabilities across data infrastructure, AI, and ecommerce to create a truly differentiated platform. The business is scaling rapidly, now powering billions of transactions annually and enabling hundreds of millions of customer interactions for some of the world’s most recognisable consumer brands.

This is a unique opportunity to join a company at an inflection point - where product innovation, market demand, and commercial momentum are all accelerating.

• Strong product-market fit, with clear ROI for customers (driving revenue, retention, and personalisation at scale)
• Backed by advanced AI and machine learning capabilities, enabling real-time decisioning
• Significant post-merger momentum, unlocking new cross-sell opportunities and accelerating growth
• Exposure to complex, high-value enterprise customers and strategic use cases
