We are looking for a Senior User Acquisition Manager to own and scale Bing (Microsoft Advertising) as a performance channel for one of our core D2C subscription products. The channel is live today, but current volumes are below what we believe Bing can deliver — you will be fully responsible for changing that: strategy, budget, campaign structures, and consistent, high-ROI growth, driving subscriptions through web funnels.

This is a hands-on role suited for someone who has already run Bing at six-figure monthly spend and knows how to scale search volume profitably. You are expected to make independent, data-driven decisions, present a clear weekly channel strategy, and deliver consistent, predictable growth. The bar is high and so is the upside — performance here is directly and significantly rewarded, and strong operators take on bigger scope fast.

• Own and optimise the Microsoft Advertising account end to end — structure, bidding, budget allocation, scaling.

• Grow channel volume well beyond current levels while maintaining efficient CPA and positive ROI.

• Prepare and present a clear weekly channel strategy with results and next steps.

• Design and refine campaign structures, keyword strategies, and bidding approaches.

• Test and scale campaign types beyond core search, including Microsoft Audience Network.

• Expand into new geos and segments based on performance data.

• Work closely with the creative team on ad copy and assets for search and audience placements.

• Test new angles and messaging strategies, scaling what performs.

• Provide data-driven feedback to guide copy and creative direction.

• Build custom performance models, analyses, and reporting in Excel, Tableau, and Mixpanel.

• Develop growth plans based on CPA, ROI, and ARPU cohort data with the data team.

• 3+ years of hands-on paid search experience, with Bing (Microsoft Advertising) as a channel you have owned.

• Experience managing six-figure monthly ad spend on Bing specifically, with clear ROI accountability.

• Proven track record scaling Bing volumes profitably — growing the channel, not just maintaining it.

• Experience driving subscriptions through web funnels (web-to-web) for D2C products (optional).

• Deep Microsoft Advertising platform knowledge: account structures, keyword strategy, bidding, and audience targeting.

• Multi-GEO experience running and scaling search campaigns across multiple countries.

• Advanced Excel skills plus proficiency in Tableau and Mixpanel — you build your own performance models and frameworks.

• Autonomous and proactive — takes full ownership of the channel and operates with minimal oversight.

• Highly analytical — every scaling and kill decision is grounded in data, not intuition alone.

• Growth-oriented — focused on finding the volume the channel is not delivering today.

• Fast under load — runs multiple campaigns, tests, and reporting streams in parallel without letting quality slip.

• Clear, direct communicator — presents insights, results, and recommendations to stakeholders.
