• Exposure to event-driven systems
• Exposure to CI/CD pipelines (GitHub Actions, Docker)

Role & responsibilities:

• Initial focus on frontend: building key UI flows, interactions, and responsive forms
• Integrate with backend services via REST and SSE
• Help define and maintain architectural consistency and code quality
• Collaborate directly with the founder/CTO, shaping the product from day one

What we offer:

• Modern architecture: no legacy, no shortcuts, full control
• Async collaboration, flexible hours, remote-first
• Direct impact: everything you build will ship to real users
• Fast feedback loop, deep technical discussions, and strong product/tech alignment
• Opportunity to grow into a core engineering or lead role

The Opportunity

We are a stealth-mode Direct-to-Consumer (DTC) startup redefining the Telehealth and Wellness landscape. We are not looking for product-market fit—we have found it. We are currently scaling aggressive 7-figure monthly budgets ($100k+ USD/day) across Meta and social channels, driving massive user growth for a suite of brands that are changing how people access health.

We are looking for a User Acquisition Lead who has mastered the Web2App funnel and is ready to trade approval committees for autonomy. If you have scaled high-velocity subscription apps in a Tier-1 product ecosystem and are ready for significant equity upside, this is your next step.

Why This Role?

• Massive Scale, Zero Red Tape: You will manage budgets that rival the biggest players in the CEE market, but with the agility of a startup. No "approval committees"—if the data says scale, we scale.
• True Ownership: You aren't just optimizing campaigns; you are defining the attribution architecture, the creative testing methodology, and the team structure.
• Financial Impact: We operate with healthy unit economics. You will see the direct impact of your work on the P&L every single day.

• Autonomy: We care about ROAS and Scale, not hours in a chair.

   

What You Will Do

• Orchestrate High-Volume Spend: Take ownership of our primary acquisition channels (Meta, TikTok), managing daily spends exceeding $100k with a focus on stable ROAS and contribution margin.
• Crack the Attribution Code: Lead the strategy on measurement, navigating web-to-app funnels, and probabilistic modeling to find truth in the data. You will work directly with our engineering team to implement CAPI and advanced pixel tracking.
• Creative Feedback Loops: Partner with the Creative Lead to build a high-velocity testing framework. You won’t just run ads; you will tell the creative team why an ad worked and what to build next based on Hook Rates, Hold Rates, and IPM.
• Scale the Team: As we grow, you will hire and mentor a squad of media buyers and data analysts, instilling a culture of "high performance, low ego."

• Market Expansion: Identify and validate new traffic sources (native, programmatic, influencers) to diversify our mix.

   

Who You Are

• You have 4+ years of experience in Performance Marketing/UA, ideally within the Health & Fitness, Telehealth, or Lifestyle app verticals.
• You have personally managed or led teams managing monthly budgets of above $500k.. The pressure of high spend doesn't scare you; it excites you.
• You are fluent in the language of MMPs, BI tools (Tableau/Looker), and pixel setups. You know that "marketing" is mostly math.
• You understand the nuances of driving traffic to web funnels before the app store to optimize conversion rates and data capture.

• Web2App Native: You deeply understand the mechanics of driving traffic to high-converting web funnels before the app store.

   

We Offer

• Top-of-Market Compensation: We pay to get the best.
• Early Equity: Real ownership in a fast-scaling venture (not phantom stock).
• Remote Freedom: Work from anywhere.
• Resources: Unlimited budget for tools, tech, and experiments that drive growth.
