Jobs at Djinni

We are looking for a Senior User Acquisition Manager (Meta Ads) to take full ownership of the Meta Ads direction on our web-based social networking platform, built for people seeking real connections across Tier-1 markets. This is a channel already spending $300K+ a month, and the mission is bold: scale it to $1M+ within a year while protecting ROAS. You will own strategy, budget, and structure end-to-end, without micromanagement, backed by dedicated MarTech, Marketing Analytics, and Creative teams so you can focus on strategy instead of technical routine. Our platform runs on a credit-based transactional model rather than a subscription one, which means repeat purchases, high LTV, and a deeper funnel to master, a genuinely different math for anyone used to standard subscription funnels. If you build fast, think in numbers, and want a clear path to Lead within 6 to 12 months, this channel is yours to grow.

In this role, you will

• Own the Meta Ads direction end-to-end: strategy, budget, campaign structure, and results
• Plan, launch, and scale campaigns within ROAS, Spend, and CAC targets
• Partner with the Creative team on hypotheses, briefs, and creative performance analysis
• Run systematic A/B tests across creatives, audiences, landing pages, funnels, and bidding strategies
• Analyze campaign results and shape requests to the Marketing Analytics team for deeper insights
• Automate routine buying processes using auto-rules, scripts, and AI tools
• Test and scale adjacent channels, such as Snapchat Ads and TikTok Ads, as part of a multi-channel strategy
• Present strategy, results, and plans at internal checkpoints and product-marketing meetings

It's all about you

• 4+ years of experience in performance marketing or User Acquisition
• Deep hands-on experience with Meta Ads, from strategy to daily optimization
• Proven track record managing budgets of $300K+ per month
• Practical experience with Snapchat Ads or TikTok Ads
• Experience with web2web funnels: landing pages, prelanders, web attribution
• Strong data-driven mindset: fluent with CPM, CTR, CPA, CAC, ROAS, ROMI, LTV, and retention, and how they connect to financial results
• Confident working with BI tools such as Tableau, Power BI, or Looker Studio
• Experience automating buying processes through auto-rules, scripts, or custom tools
• A track record of scaling campaigns without losing efficiency
• Understanding of Tier-1 markets (US, CA, UK) and highly competitive niches
• Upper-Intermediate English or higher
• Active use of AI tools in daily work, with the ability to write clear prompts and critically evaluate results, applying AI to at least two areas: data analysis and insight generation, creative hypothesis generation and copywriting, or automation of routine tasks

Would be a plus

• Experience in the social discovery niche
• Experience with transactional or credit-based monetization models
• Experience mentoring or building a team from scratch

What we offer

Care and support:

• 20 paid vacation days, 15 sick leave days, and 6 additional days off for family events

• 70% of our heads and leads have grown into their roles here – so can you!
• Performance-oriented reviews and Individual Development Plans (IDPs)
• Reimbursement for professional courses and English classes
