Principal Growth Manager - EMEA at Rzr

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 Principal Growth Manager, EMEA, you will own a book of RZR's largest and most complex accounts in the region, including top-tier gaming publishers that spend at the very top of our platform. You will be the senior expert in the room: diagnosing performance, building multi-quarter growth plans, and turning data into a case that clients' leadership will act on.

You will report to our Chief Revenue Officer and work closely with Analytics, Ad Ops, Product, and New Business. As the most senior individual contributor on the EMEA Growth team, you will also be the go-to mentor for other Growth Managers and share what works on large accounts across the team.

This role exists now because our biggest EMEA accounts are growing fast and need a senior owner with deep DSP expertise, someone who can run them independently from day one.

Key Responsibilities

Strategic Account Ownership

• Own a book of top-tier EMEA accounts and drive net revenue growth and retention against quarterly targets.
• Build and run multi-quarter growth plans for each account, with clear revenue milestones and expansion plays across User Acquisition, Retargeting and CTV.
• Lead QBRs and strategic sessions with client leadership, and build relationships well above the day-to-day contact.

Performance & Insight

• Diagnose performance shifts and run test roadmaps across creative, audience and bidding with our Analytics and Ad Ops teams.
• Translate complex technical topics such as SKAN, MMP attribution, bidding and LTV optimization into clear strategy for clients.

Revenue Operations

• Own the revenue forecast for your book and be accountable for its accuracy.
• Spot churn risk early and manage it, with clear escalation paths and documentation.

Team Leverage

• Mentor Growth Managers, share playbooks from large-account work, and bring EMEA market intelligence to leadership.

Required Skills and Experience

• 6+ years in mobile advertising or ad tech, including 5+ years client-facing in growth, account management or customer success at a DSP, ad network or programmatic platform.
• You have personally managed accounts with multi-million-dollar annual spend (ideally $1M+ per month) and grown them through a defined plan.
• Deep technical fluency in performance programmatic: bidding and auction dynamics, ROAS/LTV optimization, SKAN and MMP attribution, and creative testing.
• Strong forecasting discipline, with a track record of accurate revenue calls.
• Experience managing senior client stakeholders (VP, Head of UA and C-level).
• Fluent English; based in or able to relocate to London, with regular travel across EMEA.

Nice to Have

• Mobile gaming publisher experience, especially with large European studios.
• CTV or retargeting experience.
• Mentoring or informal team-lead experience.
• A second EMEA business language (German, French, Turkish or similar).

Why Join RZR in London?

• The biggest accounts in the region. You will hold relationships with top-tier gaming publishers, where your recommendations move millions in spend.
• A senior IC track with real influence. You will be the expert other Growth Managers learn from, with no need to move into management to keep growing.
• A small, senior team at a breakout moment. RZR is one of the fastest-growing DSPs in mobile, with a goal of becoming a top-3 DSP within two years.
• More levers on every account. UA, Retargeting and CTV under one platform, powered by machine learning built for performance.
• Upside that pays. A competitive base plus quarterly variable compensation, with accelerators for beating target.
