Job description

You build the platforms that the Growth OS runs on. Client dashboards. Internal automation tools. Data pipelines. Integration layers between ad platforms, analytics, and the creative engine. You're not a developer who writes code — you're a systems engineer who builds the infrastructure that makes growth compound at scale.

What you'll operate:

• Full-stack web applications: React/Next.js frontend + Node.js/Python backend
• Data integration layer: connecting Google Ads, Meta, GA4, BigQuery, and internal systems via APIs
• Client-facing dashboards and reporting platforms — real-time, performant, beautiful
• Internal tooling that automates manual processes and accelerates the Growth OS

What the system requires:

• 5+ years full-stack development with production-grade applications
• Expert-level React/TypeScript + Node.js or Python backend
• Database fluency: PostgreSQL, BigQuery, Redis — you know when to use what
• You've built tools that people actually use daily. You care about developer experience AND user experience.
