Senior Growth Manager (NYC - USA)

You'll Own a Real Book of Business

You'll own a book of 5–15 advertiser accounts end-to-end. You'll be the person behind the growth. The one advertisers ask when something breaks. The one our CEO checks in with when an account spikes.

Grow the revenue line. You are measured on the top-line you grow, not on activity. You communicate clearly, you drive yourself without being managed, and you stay open-minded when the data proves you wrong.

Catch problems before advertisers do. Know what each account should do next before they ask. Push budget increases, geo expansions, format tests on a schedule. Intervene before a metric becomes a complaint.

Translate between commercial and technical teams. When a partner reports cost-data drift, you debug, push our engineering teams for an ETA, and frame the response back to the partner.

What Your First 90 Days Look Like

• Days 1–30: Shadow our Senior Growth Managers on their account calls. Take over 2 small accounts (sub-€10K daily spend) and learn the backbone of our growth engine.
• Days 31–60: Take over a full book of 5–10 accounts. Own your first KPI review with our Director or CEO. Contribute with your first written process improvement.
• Days 61–90: Senior team treats you as the named owner. You're already covering for a peer's vacation. You've spotted at least one non-obvious revenue lever on your book.
• Beyond 90 days: Within a few years, the path runs from regional accounts to country ownership to multi-country or vertical leadership (gaming, non-gaming) to regional head (EMEA) or global.

What You’ll Bring

• You're hungry and looking for a challenge. You're an underdog by nature. You want to build and own real outcomes, not collect a title.
• You tell stories with data. You read the numbers, then you tell their story. A 15% cohort revenue drop on a daily view? You spot it in under 30 seconds and you explain it in two sentences a non-technical listener gets. #datastoryteller
• You're bilingual in the best sense, equally fluent and comfortable talking commercial with advertisers and technical with algorithm teams in the same day.
• Bonus Points if You Know your way around platform-marketing metrics like ROAS, LTV, retention, and ARPU. If you don't yet, you will by week 2- we'll onboard you on the math.
• You have managed a book of advertiser or partner accounts in performance marketing, mobile gaming UA, or rewarded UA. If not, we're more than willing to develop you into that role.
• You have hands-on experience with MMPs like AppsFlyer, Adjust, or Singular. You can read postbacks, navigate attribution disputes, and explain View-Through Attribution to a confused partner.
• You have built and grown a book of business in a measurable way, for example taking a €2M/yr account book to €8M/yr in 18 months.
• You have top-tier consulting (MBB) or scale-up Senior Associate background. We hire the for right thoughts. Rewarded-UA depth comes in your first 60 days.
• You have actually used Hex, worked inside the admin of a rewarded UA platform, or been on the advertiser side of one.

What Makes You a Great Fit

• Own Everything: Get It Done. When an advertiser drops 28 action items into your channel on Monday, you don't escalate. You triage, batch, and ship the 10 that matter by Friday. You don't ask for permission to fix obvious things.
• Take Initiative: Be Proactive. You spot the geo where the cap consistently under-fills. You ask the algo team why. You propose the test. You don't wait for someone to assign it.
• Move Fast: Start Simple, Iterate Quickly. You'd rather change the ROAS target today on incomplete data, watch for 7–14 days, and learn. Not wait two weeks for a perfect read. You know the stabilisation window. You don't tune at hour 3. You also don't drift past day 14 without a verdict.
• Focus on Impact: Deliver What's Most Important. You'd rather move €500K of monthly spend on the top account than €50K across five small ones. You know which accounts are load-bearing.
• Raise the Bar: Have High Standards. When something is sub-optimal, you fix it AND document it, so the next person inherits a better one. You hold the line on quality even when it would be easier not to.
