Learn more about our journey and mission on our About Us page About the RoleWe're looking for a UA Ops Specialist (Apps) — a Paid User Acquisition expert who's spent years running mobile campaigns and now wants to bring that experience to the technical and operational side of growth. You won't be optimizing bids or pushing budgets daily — our UA Managers do that. Instead, you'll be their partner-in-crime and the MarTech ambassador in the kingdom of App UA: someone who knows campaigns inside out, understands attribution headaches, and ensures every event, postback, and parameter is in place so performance is measured right. And just so we're clear: we love it if you've studied Marketing at Yale, Digital Business in Hong Kong, or anything else entirely — that's awesome. But what we value much more is your hands-on experience, the skills you've built, and above all your attitude. You'll work side by side with our Web UA Ops Specialist and our Web MarTech Specialist  — together forming a cross-functional unit that keeps UA stitched together across Web, App, and everything in between. This role is ideal for someone with 5+ years of hands-on experience running App UA campaigns who now wants to focus on ops, measurement, and future-proof attribution. Must-have 5+ years of proven, recent hands-on experience running Paid UA campaigns for mobile apps. If you still call Apple Search Ads ASA, or remember when UAC was new in Google Ads — that's a good sign you've been around long enough to have scars . Proven expertise across the main Paid UA channels for apps: Search (UAC + ASA): Solid experience with Google App Campaigns (UAC) — you know how they really work. You can talk with your AM about using negative keywords to avoid cannibalizing Search (especially in Web2App flows). You've debated the value of optimizing to tROAS, and if you've run campaigns optimized to pLTV and connected them via Measurement Protocol, that's next-level. You also know Apple Search Ads deeply, and have clear views on whether Brand campaigns really add incremental ROAS. Social (Meta + TikTok): Strong experience with Meta Ads and TikTok Ads, well beyond the basics. You can debate AEM vs. SKAN for Meta, and you know how TikTok's ADC campaigns impact MMP reporting. You're also confident working with datasets — you can identify when events are coming from the SDK vs. via CAPI. Because let's be honest — CAPI is your best friend, right? Programmatic: Broad experience with AppLovin, Unity Ads, Moloco, Mintegral, Liftoff, etc. You probably also have your own "secret DSP testing list." You know that fraud prevention (Protect360 or similar) is non-negotiable, and we'll definitely ask your opinion on click-spoofing during the interview. AdNetworks "non-traditional": If you've tested campaigns on X Ads, Reddit Ads, or other alternative networks — even better. We won't say we're running them now… but maybe we're exploring . You understand the subscription app business. Trials, renewals, cancellations, win-backs… you've seen how they play out in practice. And you don't stop at CPI or CPA — you're fluent in cohorted ROAS, predictive ROAS, LTV, predictive LTV, churn impact, and (most importantly) how UA choices ripple through the business. You've lived inside MMPs. If it's Appsflyer, even better. You've pulled raw data, built reports, and you've probably argued (or rolled your eyes) about SSOT dashboards vs. traditional attribution. You also have strong opinions on CTA vs. VTA windows and probabilistic attribution (modeled conversions). Fan or hater? We'll ask you in the interview. You know how to make Firebase useful. Not just as an analytics tool, but as a connector to Google Ads — so in-app events can actually fuel campaign optimization when it makes sense. You also know how to squeeze value out of Firebase Analytics data streams in GA4, making sure events are tracked properly and usable for UA strategy. You're curious about CTV. You know it's becoming part of the UA mix, and you understand the difference between running it purely for awareness vs. tying it back to measurable post-install events. Most importantly, you're interested in how it can fit into a subscription-driven growth strategy. Fluent English (written & spoken). You don't need to be Shakespeare (or Harry Styles ), but you must communicate clearly with UA peers, MarTech, and Data. And if you happen to speak another language — any language — even better Teach us a few words we can use when we travel (not just the bad ones, please ). Big plusExperience with server-to-server integrations (S2S postbacks, advanced SKAN setups). Ability to query data with SQL (BigQuery, Databricks) to validate MMP data vs. warehouse truth. ASO knowledge — not just install numbers, but measuring how Paid UA impacts organic installs & store rankings ("organic uplift"). Cross-pollination: curious about Web UA Ops & MarTech (Web2App flows, CAPI, CMPs), and willing to share your App knowledge back. Awareness of emerging CTV channels and how they tie into UA and subscriptions. Our Values in Action Level up. We grow, and we make our teammates grow — if you know a smarter way to do Web2App tracking, you share it with the team. See it, fix it. If you notice Product has launched an A/B test that isn't aligned with how we measure tracking, you don't stay quiet — you raise your hand. Tell the PO, the PM, or even the CEO if needed. Always ahead. ATT tightening? SKAN 5? You're testing before the industry headlines hit. Now means now. If CAPI breaks on Friday, you don't push it to next sprint — you raise it and propose a fix today. Team spirit. You're the MarTech ambassador in the kingdom of App UA — speaking the same lingo as UA Managers, while making sure attribution is stitched together Ownership. If App Campaigns underperform because of a broken setup, you don't just escalate — you bring solutions. Why Join Our Team Be the bridge between UA and Tech. You'll bring deep campaign experience and elevate it with operational and technical mastery. Work hand in hand with Web UA Ops + MarTech. Together, you'll form a cross-functional team that makes sure UA (App & Web) runs on clean, reliable, and future-proof setups. Real ownership of UA execution. You won't just follow playbooks — you'll help write them. Room to grow. This department is new and scaling fast, so there's plenty of space to expand your role. Future opportunities. Beyond subscriptions, you'll help us explore channels like ASO uplift, CTV, and alternative networks. We're nerds at heart. If you love arguing about CTA vs. VTA, whether SSOT dashboards actually help, or why TikTok ADC breaks reporting — you'll fit right in. Your voice matters. We want someone who challenges assumptions and speaks up when things don't add up. WHY SHOULD YOU JOIN US?Growth and career development At Leadtech, we prioritize your growth.
