About the role
We are looking for a Data Engineer who can own and deliver across data engineering tasks, integrations, and marketing systems. This is not a junior learning role: we need someone who can quickly understand production systems, solve problems independently, and ship reliable work.

Help move and transform data across BigQuery, GCS, Pub/Sub, ClickHouse, and external systems

Troubleshoot pipeline, tracking, payment, and data quality issues

Support payment orchestration data flows, including subscriptions and payment processing

Growth Areas
You will develop across GCP infrastructure and DataOps, dbt, BigQuery, ClickHouse, Git, CI/CD, and software engineering practices. The role also includes exposure to internal monitoring platforms built with brokers, microservices, alerting, and observability tools, helping you grow system design skills through real production problems.

Key Success Factors
Proactivity: we need someone who notices issues, asks questions early, follows through, and takes ownership without waiting for detailed instructions.
High availability: on release days or during urgent tracking/payment setup, you should be ready to help in the evening when needed.
Delivery mindset: the goal is not only to learn, but to deliver reliable work across data engineering, marketing systems, payment flows, and internal platforms.
