Who Are We?

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

The Chief of Staff to the COO is a high-impact role at the center of how RZR executes on its most critical priorities. You will serve as a trusted partner to the COO, acting as an extension of senior leadership to ensure that strategic direction translates into clear plans, defined ownership, and measurable outcomes.

You will work across every function — Product, Engineering, Analytics, Sales, Finance, and People Ops — to remove friction, surface risks early, and keep the organization focused on its highest-leverage work. This is not a coordination role. You will own initiatives end-to-end, step in directly when execution stalls, and be expected to drive outcomes without needing authority to do so.

The ideal candidate is a strong operator and analytical thinker who thrives in ambiguity, communicates with precision, and brings relentless follow-through to everything they touch.

Key Responsibilities

• Lead end-to-end execution of high-priority strategic and operational initiatives, from problem definition through delivery and follow-through

• Translate ambiguous or high-level direction into clear plans, milestones, ownership, and success metrics

• Partner with cross-functional leaders across Product, Engineering, Analytics, Sales, Finance, and People Ops to manage dependencies and ensure timely delivery

• Act as a central coordination point for cross-functional initiatives, proactively identifying and resolving execution risks before they become blockers

• Build structured analyses, decision memos, and business cases to support leadership decision-making

• Run analyses, deep dives, or special projects directly when needed to unblock progress or accelerate outcomes

• Establish and manage operating cadences, including weekly reviews, monthly planning cycles, and executive readouts
