The position at a glance
We are seeking a highly skilled Senior Database Administrator to provide expert-level support, administration, and architectural guidance for our core database estate, specifically focusing on Sybase (ASE/IQ) with Replication Server, Microsoft SQL Server with Always on, and MongoDB replica sets. The successful candidate will manage a hybrid environment of legacy relational systems and modern distributed NoSQL databases within a Corporate and Investment Banking (CIB) Infrastructure setting, ensuring high availability, security, and seamless data synchronization across the enterprise.
In detail
Operations & Incident Management
- Provide 24/7/365 L3/L4 support for mission-critical Sybase, MSSQL, and MongoDB environments.
- Participate in an on-call rotation for after-hours/weekend support (including hotline coverage 7:30 AM–6:30 PM, Mon–Fri).
- Triage and resolve complex critical incidents (e.g., Sybase Replication latency/errors, MSSQL Always On failures, MongoDB replica set elections, or node outages).
- Automate remediation for common failures (e.g., automated reconciliation of replication queues).
Lifecycle Management & Migration
- Install, configure, patch, and upgrade Sybase, MSSQL, and MongoDB instances in accordance with security baselines.
- Manage and maintain Sybase Replication Server environments to support data distribution and integration.
- Execute zero-downtime migrations for End-of-Life (EOL) systems (e.g., migrating legacy Sybase workloads to MSSQL, upgrading EOL SQL Server versions, or migrating legacy MongoDB versions to current stable releases).
- Plan and execute schema migrations, data modeling changes, and index optimizations specific to both RDBMS and NoSQL architectures.
High Availability, Replication & Disaster Recovery
- Administer and optimize high-availability and data synchronization configurations:
- Sybase: Replication Server (RSS), managing topologies, agent configurations, and resolving replication bottlenecks/latency.
- MSSQL: Always On Availability Groups, Failover Cluster Instances (FCI).
- MongoDB: Replica Sets and Sharded Clusters.
- Manage Backup & Recovery: Ensure Point-in-Time Recovery (PITR), snapshots, and cross-region Disaster Recovery (DR) for all three platforms.
- Conduct regular DR compliance testing, including RPO/RTO validation and failover drills.
Performance Engineering & Monitoring
- Monitor and tune database performance (e.g., MSSQL execution plans, Sybase query optimization, and MongoDB query profiling/compaction).
- Diagnose and resolve Sybase Replication issues, including latency, throughput bottlenecks, and data discrepancies between source and target.
- Automate performance baseline using tools such as Grafana, or native tools (e.g., SQL Server Profiler/Extended Events).
Security & Compliance
- Enforce strict database security baselines (e.g., Transparent Data Encryption (TDE), Role-Based Access Control (RBAC), network encryption, and audit logging).
- Remediate vulnerabilities (CVE patches) and ensure compliance and internal audit policies.
- Collaborate with Cybersecurity to harden databases against injection attacks and unauthorized replication/access.
Architecture & Strategy
- Design and deploy scalable, fault-tolerant architectures (e.g., sharded MongoDB clusters or highly available MSSQL environments).
- Develop standardized runbooks, provisioning procedures, and naming conventions.
- Identify operational risks (e.g., single points of failure or replication lag) and mitigate them through redundancy and automation.Bachelor’s or master’s degree in computer science, Computer Engineering, or a related field
