Why Work With Us?

Not Meeting Every Skill?

We are an iGaming media buying team focused on Facebook traffic acquisition across Tier 1–2 GEOs under the CPA model through external affiliate programs.

We provide the full infrastructure needed for traffic acquisition, including accounts, farming, creatives, offers, analytics, and technical support.

We are looking for a hands-on Team Lead who can combine strong media buying expertise with team leadership. You’ll be responsible for managing a team of buyers, monitoring performance, supporting launches, analyzing traffic, and making sure the team consistently delivers strong results — while continuing to run traffic yourself.

HOW YOU WILL MAKE AN IMPACT:

• Manage and develop a team of approximately 5–6 Media Buyers;
• Monitor the team’s traffic performance and identify opportunities for optimization and growth;
• Monitor the full funnel from click to registration and deposit;
• Analyze key performance metrics such as CPM, CTR, CPC, CR, CPA, ROI, approval rate, and other relevant indicators;
• Identify campaign bottlenecks and decide whether to optimize, scale, or stop campaigns;
• Take into account holds, caps, qualification requirements, and actual revenue when evaluating campaign performance;
• Compare buyer performance and share successful approaches and working strategies across the team;
• Support buyers with campaign launches, optimization, and troubleshooting;
• Generate and validate hypotheses around creatives, funnels, offers, and GEOs;
• Monitor the quality and results of campaign testing;
• Scale validated approaches across the team;
• Personally launch and validate campaigns and priority hypotheses;
• Monitor the market and stay up to date with changes in iGaming and Facebook media buying;
• Use AI tools for analytics, performance analysis, hypothesis generation, and daily workflow optimization;
• Identify opportunities to improve and automate the team’s buying processes;
• Analyze performance drops and identify their causes based on data;
• Help onboard and mentor new buyers and support their professional development.

WHAT WILL HELP YOU SUCCEED IN THE ROLE:

• 2+ years of hands-on experience with Facebook Ads in Gambling/iGaming;
• 1+ year of experience managing a team of Media Buyers;
• Strong practical experience working with the CPA model;
• Recent and relevant experience in iGaming — you should be actively familiar with the current gambling media buying market;
• Proven experience working with Tier 1–2 GEOs;
• Strong understanding of the full traffic funnel and key performance metrics;
• Experience independently launching and optimizing Facebook campaigns;
• Experience managing and scaling significant traffic volumes;
• Experience managing a team of approximately 5–6 buyers;
• Previous team experience with approximately $200K+ in monthly spend is highly relevant;
• Experience generating approximately $30–40K+ in personal monthly spend is a strong advantage;
• Experience with Binom, Keitaro, or similar tracking platforms;
• Understanding of BMs, advertising accounts, and the general Facebook buying infrastructure;
• Strong analytical mindset and ability to make decisions based on data;
• Ability to identify problems quickly and take ownership of the result;
• Practical experience using AI tools in media buying, analytics, or workflow optimization;
• Willingness to remain hands-on and continue running traffic personally, rather than moving entirely into people management.

WHY YOU'LL LOVE IT HERE:

• Flexible working hours and a remote work setup, so you can plan work around your life and not your life around work!
• Unlimited vacation days and paid sick leave—because your rest matters.
• A competitive compensation that truly reflects your skills and expertise.
• Employee referral bonus and gifts to celebrate your special occasions.
• 50% financial support for learning expenses to supercharge your professional growth!

Ми — команда Lean Startup фахівців, для яких підприємництво, startup culture та продуктове мислення — це не просто частина роботи, а основа нашого підходу.
Ми не працюємо у форматі “просто виконати всі побажання клієнта” чи додати якомога більше фіч заради фіч.
Наш фокус — не в тому, щоб витрачати бюджет, а в тому, щоб допомагати клієнтам швидко перевіряти ідеї, знаходити реальну цінність для користувачів і запускати продукти, які мають потенціал вирости у сильний бізнес.
За 3 роки на ринку ми запустили понад 70 стартапів з нуля та працювали з клієнтами з різних країн світу. Наш досвід у стартапах, hands-on підхід і використання Lean Startup методології допомагають нам рухатися швидко, гнучко й ефективно.

• вміння ефективно керувати декількома проєктами одночасно, визначати пріоритети та тримати фокус на найбільш важливих задачах;
• проактивність та ownership — здатність не чекати готових відповідей, а самостійно знаходити інформацію, помічати проблеми та рухати команду й продукт уперед;
• сильні комунікаційні та організаційні навички.

Буде плюсом:

• досвід управління проєктами з розробки mobile applications;
• знання Lean Startup методології та розуміння підходів до пошуку Product-Market Fit;
• розуміння основ UX/UI та User Interface Guidelines для iOS та Android;
• технічний бекграунд або достатня технічна база, щоб розуміти, як продукт працює “під капотом”, ефективно комунікувати з developers та брати участь в обговоренні технічних рішень;
• досвід роботи з аналітичними інструментами, наприклад Firebase, Mixpanel або Amplitude, та вміння використовувати дані для прийняття продуктових рішень;
• впевнене володіння ClickUp та вміння налаштовувати його під процеси команди, а не процеси команди під можливості інструменту.
