• Optimize compute usage and cost efficiency (FinOps) across data platforms and workloads
• Manage code lifecycle using Git and CI/CD pipelines
• Ensure high-quality delivery through automated testing, data validation and integration testing
• Implement observability practices, including logging, monitoring and performance tracking

Requirements:

• 2+ years of experience with Python for software engineering (not just scripting)
• Advanced SQL skills, including performance tuning and working with large-scale data systems
• Experience with modern data platforms such as Snowflake or Databricks
• Familiarity with CI/CD pipelines and version control best practices
• Understanding of data modeling and scalable architecture principles
• English proficiency at B2 level or higher
• Experience with cloud security and governance models
