Hi, we are a fast-moving product team launching a next-gen AI Harness product (business, marketing, education). We have already stabilized unit economics at $100k/mo. Now, we are ready to scale to $1M+/mo.

A $100k foundation is just a starting signal. We aren't looking for a passive optimizer to maintain a running machine. We need a builder who can pressure-test what exists, tear it down, and rebuild the engine from scratch if the current setup breaks at scale.

The Reality Check:
You report directly to the CEO. Flat structure, zero bureaucracy, and a budget that scales as fast as you can prove ROAS. It's not a dashboard-watching role. You personally run the global Google Ads engine from initial validation to deep optimization. You won't have a 50-person engineering team or a ready-made playbook.

If you want total freedom to scale an acquisition engine from $100k to $1M+ a month - this is your playground. If you need a fully stable corporate environment to feel comfortable, it's not your perfect role.

Your Mission

• Own the Engine: audit, validate, and rebuild the Google Ads strategy (search-first, global markets) from scratch.
• Aggressive Scaling: push the current $100k/mo foundation to a profitable $1M+/mo, tearing down any setups that break.
• CEO Collaboration: work directly with the CEO on budget forecasting, growth planning, and P&L strategy.
• Data-Driven Growth: deep-dive into funnel data to optimize the entire user journey from impression to conversion.

What Makes You the Perfect Fit

• Proven Scalable Track Record: a real case of building a Google Ads channel across global markets from a blank account to significant profitable spend (up to $1M and more).
• Absolute Hands-on Mastery: direct practitioner who knows search inside out and knows how to hit CPA/ROAS targets.
• Product Mindset: fluency in SaaS and mobile metrics (LTV, CAC, retention, churn, payback period).
• Technical Independence: expert setup of Google Ads, GTM, and tracking architectures (GA4, AppsFlyer, or Adjust) from scratch.
• High Agency: thrives in ambiguity, acts without waiting for instructions, and pivots fast based on hard data.
• Language: Upper-Intermediate (B2+) English or higher.

What's in It for You

• Total Freedom: zero micromanagement with absolute control over strategy, execution, and budgets.
• Uncapped Budgets: access to unlimited marketing budget as fast as you can prove profitable ROAS.
• Zero Bureaucracy: test and launch new ideas in hours, not weeks.
• AI Domain: hyper-growth product in the world's fastest-growing tech sector.

Perks & Benefits

• Remote-First & Coworking Coverage: work from anywhere globally, with your coworking space membership covered.
• Time Off to Recharge: 20 working days of fully paid vacation per year, plus paid sick leave.
• Learning & Growth: compensation for professional courses, conferences, specialized workshops, and intensive English training.
• Healthcare: comprehensive medical insurance, and access to corporate doctor.
