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.

About us

We’re building Interview Assistant AI - a web-based AI product that helps people prepare for and go through interviews with more confidence.

Our product philosophy is Activation-First:

• honest expectations from the first screen,
• reduced first-time user anxiety,
• safe practice before real interviews,
• no hype, dark patterns, or fake metrics.

You’ll work with clear product specs, a focused scope, and a small product team that values calm, thoughtful execution.
 

What you’ll work on (Phase 1)

This role is focused on a short, clearly defined execution phase.

At a practical level, you’ll:

• implement landing page and dashboard UI changes
  (no redesign, no copywriting - specs provided),
• add PostHog analytics on the frontend,
• implement backend events for:
  • interview lifecycle,
  • AI output generation,
  • activation and failure states.

The goal is to ship a clean activation flow and reliable analytics, without over-engineering.
 

How we like to work

We’re looking for a developer who is comfortable working from clear specs, and who also:

• points out simpler or more efficient ways to implement things,
• suggests better technical approaches (especially for analytics),
• surfaces tradeoffs when an implementation choice could affect timeline, cost, or risk,
• asks questions if something is ambiguous.

You won’t be expected to define product direction but your technical judgment is welcome and valued.
 

What this role is not

• No UX redesign
• No product discovery
• No experiments or A/B testing
• No growth dashboards
• No rewriting copy

This is a focused execution phase with clear boundaries.
 

Tech stack & experience

Must have

• React (or similar SPA framework)
• Backend experience (Node.js or similar)
• Experience with analytics tools (PostHog, Segment, Amplitude, etc.)
• Comfortable working with an existing codebase
• Clear written communication

Nice to have

• AI / LLM integrations
• Stripe or payments experience (future phase)
   

What’s next

Phase 1 is short and activation-focused.

If things go well, there may be follow-up work later (AI model updates, API / Stripe work), but the immediate focus is Phase 1 only.
 

Please be ready to answer a few short questions after the first contact.
