Troubleshoot production incidents, perform root-cause analysis, and lead remediation and post-incident reviews.
Collaborate with developers and application teams on schema changes, queries, and migration strategies; review DDL/DDL changes.

Scripting & automation: Proficient in Bash, Python, or PowerShell for automation and tooling.
Security & compliance: Knowledge of encryption, RBAC, auditing, and data protection regulations.
Soft skills: Problem-solving, clear communication, documentation discipline, and ability to collaborate across teams.
