Senior Growth Manager - EMEA

Who Are We?

RZR is an AI-native advertising platform built for the next era of performance marketing. We operate at the intersection of machine learning, programmatic media, and full-funnel mobile growth, powering campaigns for some of the world's most ambitious advertisers. Our platform is purpose-built to deliver outcomes at scale, not just impressions.

We are a team of builders, operators, and technologists who believe the advertising industry is overdue for a fundamental rethink. We move fast, operate with a high degree of ownership, and hold ourselves to an exceptionally high standard of craft.

RZR is scaling aggressively with an active M&A pipeline and a platform vision that puts us on a path to becoming an industry leader. This is a rare opportunity to join a company at an inflection point and help shape what it becomes.

Role Overview

As a Senior Growth Manager based in London, you will own a portfolio of strategically significant accounts across the UK and Western EMEA, driving revenue retention and growth for some of the most commercially important relationships in the region. This is a senior individual contributor role. You will operate with full autonomy from day one: leading your own growth plans, managing executive-level client relationships, and executing across the full account lifecycle without co-management.

You will work closely with cross-functional teams across Growth, Analytics, and Operations to launch and optimize campaigns, surface performance insights, and translate data into decisions that move the business. You will report to the EMEA Growth lead and collaborate with a lean, senior team that moves fast and holds itself to a high standard.

This role sits at the heart of RZR's EMEA strategy. The region manages a combined book of over $110K DRR across 30+ accounts, with a strong new business pipeline, and we need a senior operator who can own a meaningful portion of that portfolio independently and grow it.

• Proven ability to build high-touch client relationships, manage in-person engagements, and calibrate the right frequency and depth of contact

• Comfortable managing the full account lifecycle in a commercially dense, competitive market
• Willingness to travel regularly and engage clients and team members in person
