Job Description

Are you a proactive, team-oriented, and motivated Data Engineer (Mid or Senior) looking for your next challenge? If you enjoy building robust, high-throughput data platforms, optimizing complex pipelines under heavy load, and working with cutting-edge technologies—including GenAI and modern lakehouse architectures—we'd love to have you on board!

Your role

You will build and operate our client's data platform end-to-end, covering data ingestion, warehousing, lakehouse architecture, and platform operations.

Your primary focus will be designing and operating high-volume ingestion into ClickHouse from Kafka, BigQuery, Elasticsearch, cold storage, and third-party APIs. Beyond ingestion, you'll contribute to data modeling, pipeline development, data quality, observability, and platform reliability across the entire data stack.

As a Mid-level Data Engineer, you'll independently deliver well-defined pipelines with light guidance.

As a Senior Data Engineer, you'll own platform subsystems end-to-end, define engineering best practices, mentor teammates, and drive architectural decisions.

Engineering excellence

• Experience integrating third-party APIs, including authentication, pagination, rate limiting, retries, error handling, and incremental data loading.

• Experience building reliable, observable, and maintainable data systems with a focus on monitoring, reliability, and operational excellence.

Ways of working

• Comfortable using AI-assisted development tools (e.g. Claude Code, Cursor, GitHub Copilot) as part of your daily engineering workflow.

• Strong communication skills and the ability to work independently while collaborating effectively within a team.
