Codeway is a integral consumer technology company building apps people love. Since 2020 we've launched 60+ mobile apps — including flagship apps Retake AI, Cleanup, Learna, and DramaPops — reaching 400M+ users worldwide, and in 2024 we were the #1 most-downloaded iOS publisher. We're 300+ people across İstanbul and Barcelona, a #1 LinkedIn Top Startup, and a Great Place to Work in Europe.
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.
You won’t touch all of this in your first months — the platform surface spans ingestion, transformation, the warehouse, and the BI layer, and we’ll bring you onto it deliberately.
