• Manage cloud-based data infrastructure and storage solutions across platforms such as Databricks, AWS, Snowflake, and Google Cloud.
• Build operational tooling and monitoring dashboards to track pipeline health, resource utilization, uptime, and system performance.
• Collaborate with Data Science, Analytics, Product, and Engineering teams to deliver trusted and scalable data assets.
• Maintain source control, CI/CD processes, repository standards, and deployment best practices across data platforms.

Qualifications

What we look for:

• 3-5 years of experience in Data Engineering, Analytics Engineering, or related disciplines.
• Experience with cloud-based data platforms such as Databricks, AWS, Snowflake, or Google Cloud.
• Familiarity with integrating AI and automation tools (e.g., GitHub Copilot, Natural Language Query tools) to enable you to move faster and deliver higher quality code.
• Strong proficiency in SQL and Python.
• Experience with Spark and distributed data processing (PySpark preferred).
