- Design and operate high-availability architectures (replication, backups, disaster recovery, failover)
- Lead performance tuning, capacity planning, and database lifecycle management
- Diagnose and resolve complex issues across the stack (query → database → OS → storage/network)
- Drive automation of provisioning, patching, migrations, and maintenance workflows
- Contribute to Infrastructure-as-Code and Kubernetes adoption for stateful workloads
- Partner with engineering, data, and research teams to improve platform usability and resilience
Your present skillset:
- 5+ years of hands-on experience as a Database Administrator in production environments (PostgreSQL, MySQL, or similar; familiarity with NoSQL systems is a plus)
- Strong experience with high-availability setups, replication (logical/physical), failover mechanisms, and disaster recovery strategies (PITR, backup automation, restore validation)
- Proven expertise in performance tuning and query optimization (execution plan analysis, indexing strategies, workload optimization, capacity planning)
- Deep understanding of Linux and infrastructure fundamentals (compute, storage I/O, networking, filesystem and kernel tuning)
- Experience with automation and Infrastructure-as-Code tools (Terraform, Ansible, Helm, or similar) and scripting (Bash/Python)
- Strong troubleshooting skills in distributed systems and complex production environments
- Solid knowledge of database security (access control, encryption in transit/at rest, secrets management, auditing)
- Ownership mindset and ability to operate effectively in a high-performance environment
Nice to have:
- Experience in high-throughput or low-latency environments
- Exposure to Kubernetes for stateful services
- Observability experience (metrics, logs, SLOs)
- Programming ability (Python, Go, Rust, or similar)
