Data Engineer

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).
• Contribute to the Looker/LookML semantic layer (PDTs, datagroups, derived views, explores).
• Build with agentic coding tools (Claude Code, Google Antigravity) every day, and help keep our internal knowledge base sharp.

Grow into over time

• Real-time/streaming ingestion through Pub/Sub and Dataflow.
• 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.
• Marketing-platform ETLs and attribution/growth KPIs.

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., * 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., * 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.
• A marketing-analytics brain - attribution, retention, conversion, ROAS, LTV.

• Solid programming fundamentals - sound programming principles, data structures, and clean, maintainable code. The language matters less than how you think.
• 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.

Day one we really expect: SQL and one general-purpose language (we work across Node.js/TypeScript and Python). Everything else below, we’ll teach., Other - a Bachelor’s or higher in Computer Science, Software Engineering, or a related field, or equivalent practical experience.

Codeway is a global 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.
