About Codeway Codeway builds category-leading consumer AI apps on mobile and web, at general scale. Completely bootstrapped. We turn category wins into six focused vertical companies: Wishlabs (AI Creativity), Wellture (Wellness), Learna (Education), Sparked (Media), Cosmic Jam (Entertainment), and Catalyst Apps (Utilities & Productivity).

Every idea born here starts with an unfair advantage: the platform, the people, and the profits of every product before it. You'll join Cerebro, the team that builds and runs the data platform behind 60+ Codeway apps and 400M+ users. This is the layer where streaming events become trustworthy numbers — the retention, conversion, and attribution that product, marketing, and the executive team act on every day.

You'll start owning real pipelines and warehouse models on a modern Google Cloud stack, with the team alongside you, and grow into more of the platform as you go. You'll also ship with agentic AI tools as a real part of how we work — this is AI-native data engineering. If you like owning data end to end, from a Pub/Sub event to a Looker explore, and want scale you can't get just anywhere (hundreds of millions of users), you'll feel at home here.

Build and maintain data pipelines that ingest events reliably into the data platform. Write SQL and build/maintain warehouse models that feed analytics and BI. Help keep our BigQuery warehouse fast and cost-aware (partitioning, clustering, sensible schemas).

Build with agentic coding tools (Claude Code,



Google Antigravity) every day, and help keep our internal knowledge base sharp. Transformation and orchestration with dbt and Airflow. Reading and making changes in our distributed Node.js services (event routing, conversion matching, receipt verification) where pipeline work lands.

An AI-native way of working — you build alongside agentic coding tools (Claude Code, Google Antigravity) and judge their output critically, rather than trusting it blindly. Solid programming fundamentals — sound programming principles, data structures, and clean, maintainable code. Comfortable with SQL and data modeling — you can write non-trivial SQL and reason about how to structure data.

You've built and owned a data pipeline — through a personal project, coursework, an internship, or production work. No prior professional experience required. Fluency in English — you communicate and document clearly across product, marketing, analytics, and engineering.

A Bachelor's or higher in Computer Science, Software Engineering, or a related field. SQL and one general-purpose language (we work across Node.js/TypeScript and Python). Hands-on with any cloud data warehouse (BigQuery especially) and GCP (Pub/Sub, Dataflow, Cloud Functions, Cloud Run, GKE, Firestore, GCS).

A modern analytics & transformation stack — Looker/LookML, dbt, Airflow. Comfort with Docker/containers and a feel for how distributed data processing behaves.
