• Solid SQL skills, with experience across relational databases and/or cloud data warehouses.
• Experience with distributed data processing at scale (e.g., Spark) or comparable large-scale data systems.

• Add instrumentation, alerting, and automated tests so problems surface before reaching a client.
• Contribute to infrastructure-as-code and CI/CD pipelines.
• Participate in code reviews, incident response, and knowledge sharing across the team.
