  • Collaboration:
  • Work closely with cross-functional team members, including operations, DBAs, and other developers, to improve reliability, scalability, and developer productivity.
  • Participate in agile ceremonies to foster effective collaboration within the squad.
  • Engage in knowledge-sharing activities and contribute to the collective expertise of the team.
  • Documentation and Monitoring:
  • Document infrastructure, code, scripts, and configurations to ensure maintainability and knowledge transfer within the squad.
  • Monitor system health, capacity, performance, and costs; establish monitoring rulesets and alerting.
  • Security and Administration:
  • Secure the software supply chain and enforce least-privilege access.
  • Administer and automate Oracle and PostgreSQL operational tasks, including migrations, backups/restores, replication, upgrades, and performance tuning in both cloud and on-prem setups.
