Job description

Exclusive | L4 Customer Success Manager – Enterprise CDP / MarTech | EMEA | London

4 days per week in NYC office (typically Friday WFH) - please do not apply if you cannot do this.

I'm working exclusively with one of the most recognized names in the Customer Data Platform & eCommerce space.

You'd be joining the product org behind a real-time customer data platform (CDP) trusted by some of the world's largest retailers and ecommerce brands — the layer that lets companies collect, unify, and activate customer data across every channel while keeping full ownership and control of it (no black-box vendor lock-in, which is a genuine differentiator in this space).

Recently, this company merged into one of the fastest-growing, profitable ecommerce marketing platforms around — a $XXXM+ deal that kept the original founder and product leadership team fully in place, not stripped out. The parent business is now running north of $900M in annualised revenue, up ~50% year-over-year, already EBITDA-positive, and has been valued anywhere from $3.5B to $7B+ across recent funding rounds while it tracks toward a public listing.

Customers using both platforms together see outcomes up to 50% better than best-in-class point solutions — which is exactly why CDP investment is doubling post-merger, not shrinking.

Translation for candidates: startup-grade ownership of a real, technical product with genuine enterprise customers, inside a business with proven hypergrowth and a credible path to IPO. That combination is rare.

They're hiring a Strategic/Director level candidate as a CSM for their US book of business — and this is the real deal. Enterprise accounts. C-suite relationships. A platform that genuinely moves the needle for the brands using it.

The role in a nutshell:

Own a portfolio of strategic, high-revenue global accounts. Drive retention and expansion. Build exec-level relationships. Translate complex customer data strategies into measurable business outcomes. Lead QBRs that actually mean something. Be the voice of the customer back into Product.

You’ll be a strong fit if you have:

• 5+ years in CSM / AM / Solutions Consulting in enterprise SaaS
• A background in CDP, MarTech, data infrastructure, or developer-adjacent platforms
• Proven track record managing large, complex, global accounts (ideally $250k+ ACV)
• Able and willing to work from NYC office 4 days per week
• An AI-first mindset — you use the tools, you don't just talk about them

• The package includes equity (every employee is a shareholder), strong benefits, and a genuinely collaborative, high-performance culture. NYC HQ'd and 4 days a week in the office requirement.
