Middle/Senior User Acquisition Manager

We’re looking for a User Acquisition Manager to scale 51 Games products through performance marketing - with a strong focus on mobile and browser games. You’ll own paid acquisition from strategy to daily execution: launching and optimising campaigns, building a repeatable testing framework, and partnering with creative + analytics to push ROAS, lower CPD/CAC, and grow LTV.

This role is for someone who is comfortable managing high-volume budgets, moving fast with experiments, and making decisions based on real performance data - not opinions. You will be a part of acquisition team, including 2 other specialists.

Responsibilities
• Own and execute the UA strategy across Meta, Bing, Google (Search/Display/YouTube), X/Twitter, DSP/programmatic, and CPA/CPM networks—aligned with marketing, live-ops, seasonality, and product releases;
• Set and manage growth KPIs (CAC/CPA, ROAS, CVR, retention, LTV, payback) and translate them into clear channel/geo/segment targets;
• Launch and scale campaigns: account structure, naming conventions, budgets, pacing, and bidding to consistently hit performance goals;
• Optimize daily across audiences, bids, placements, creatives, and funnel steps; quickly diagnose issues (creative fatigue, audience saturation, tracking drops, funnel friction) and fix them;
• Run a structured experimentation loop (test → learn → scale) with documented hypotheses, success criteria, and learnings;
• Build segmentation and lifecycle loops: prospecting, retargeting, re-engagement/winback from install → activation → purchase/deposit;
• Drive the creative performance system with design/copy: briefs (angles/hooks/messages/formats), UGC/short-form video + statics, and continuous A/B testing with a “what works” library;
• Own analytics and reporting across GA4/Ads Managers/dashboards; monitor cohorts and funnel metrics (D1/D7/D30, payer conversion, LTV) and deliver actionable insights, Custom Data Analytics tools;
• Manage programmatic and external partners: DSP buying basics (reach/frequency, brand safety), CPA/CPM partner onboarding/optimization, fraud prevention, vendor terms, and budget/forecasting/ROI tracking — while ensuring policy/legal compliance and staying on top of competitor trends;
• Retention campaigns — Drive retention through narrow and segmented targeting on the existing audience (activation + re-activation).

 

Requirements
• 2+ years in paid UA/performance marketing for mobile games (browser games experience is a strong plus);
• Hands-on expertise with Meta + TikTok (must-have), plus at least one of: Google UAC/YouTube, DSP/programmatic, networks;
• Proven experience improving ROAS / CPD / CAC through testing, optimisation, and creative iteration;
• Strong analytical mindset: ability to interpret cohorts, funnels, and campaign signals to make decisions;
• Experience working closely with creatives and turning data into actionable briefs;
• Comfortable in a fast-paced environment with rapid testing and frequent iteration;
• Strong English communication.

Nice to have
• Experience with MMPs (e.g., AppsFlyer / Adjust / Branch);
• Experience with playable ads, influencer whitelisting, or hybrid UA + creator performance campaigns;
• Understanding of monetisation design and game economies (F2P loops, offer testing);
• Experience scaling across multiple geos (Tier 1 + emerging markets).
