About the role

We are looking for a highly systematic Head of User Acquisition to own and scale paid acquisition for one of our core D2C subscription products. You will be fully responsible for building a stable, structured, high-ROI traffic operation — defining the strategy, managing the budget, leading the team, and driving consistent, predictable performance across all paid channels. The core challenge is not just scaling spend — it is diversifying a concentrated channel mix and profitably scaling new channels and geos to reduce platform dependence.

This is a high-impact role suited for someone who thinks in systems, not campaigns. Performance instability, inconsistent execution, and unresolved issues are not acceptable. You are expected to operate with structure and rigour at all times, while acting as the key bridge between product, creative, and analytics. The bar is high and so is the upside — performance here is directly and significantly rewarded, and strong operators take on bigger scope fast.

Collaborate with the Managing Director to align UA strategy with product and business goals

Work closely with creative leads to guide ad production using data-driven briefs

Must-Have Experience

Proven track record managing paid acquisition at scale across multiple platforms

Experience managing significant monthly paid budgets with clear ROI accountability

Demonstrated ability to build systems, SOPs, and reporting structures — not just run campaigns

Experience directly managing and developing a UA team of at least 3–5 professionals

Deep platform knowledge: Meta, TikTok, Google, Pinterest, Snapchat, and other paid social/search/display

Strong quantitative and analytical skills with proficiency in Tableau, Google Analytics, and Excel/SQL

Leadership Attributes

Highly systematic and structured operator — you build processes, not workarounds
