Lead Full-Stack Engineer (Mobile + Payments) – Founding Team

The Mission:
We are a high-growth digital advertising agency. We are moving from "services" to "products" and need a technical leader to build and own our mobile ecosystem. You aren't just an employee; you are the lead architect of our tools and applications.

What You Will Own:

Full-Stack Mobile: Architecting and deploying iOS and Android apps using a single-codebase framework (Flutter or React Native).

Payments & Logic: Implementing complex payment flows (Stripe, Apple In-App Purchases, RevenueCat) and ensuring 100% security and reliability.

UI/UX Leadership: Designing clean, high-converting interfaces in Figma and translating them into pixel-perfect code.

AI Integration: Utilizing Cursor and Claude to build at 10x speed, while maintaining high code quality and internal documentation.

Requirements:

Experience: 5+ years in full-stack dev, with at least 2 years leading a team or shipping solo apps from 0 to 1.

Mobile: Expert in Flutter (preferred for 2026 performance) or React Native.

Backend/DevOps: Mastery of Supabase, Firebase, or PostgreSQL; comfortable with serverless functions and rapid deployment.

Design: You have a "design eye." You can take a rough concept and make it look premium without a dedicated designer.

Ad-Tech Knowledge: You understand pixels, postbacks, and how to integrate tracking APIs (Meta/Google).

The "Alpha" Requirement:
We don't do slow. You must be an expert in "Vibe Coding"—using AI tools to bypass the boring parts of development so you can focus on the hard logic and user experience.
