Junior Database Engineer

Stampede Solution; Kuala Lumpur; On-site; MYR 60,000 - 90,000; Full time

Job summary

Jora Malaysia is seeking a Database Administrator to manage MySQL/MariaDB/Percona across production, DR, UAT and development. You will configure, monitor and back up databases, implement clustering and failover, and document procedures and changes.

It’s a hands-on role requiring 1–3 years of DB administration, Linux expertise, strong SQL, and scripting ability. You’ll work with RDS/Aurora and on-call DR drills, based in Kuala Lumpur.

Qualifications

• 1–3 years’ experience administering MySQL or a comparable relational database. Fresh graduates with strong SQL and Linux fundamentals are welcome to apply.
• Proficient in Linux administration on the command line — filesystems, permissions, services, storage, and process and resource troubleshooting.
• Strong SQL, and a working understanding of relational design, indexing, transactions and isolation levels.
• Understanding of replication, clustering, backup strategies and disaster recovery — and able to explain the trade-offs between them.
• Scripting in Bash or Python to automate routine tasks and checks.
• A methodical approach to production change, including testing the rollback before applying the change.
• Clear written English for runbooks, change records and handover notes.
• Degree or diploma in Computer Science, Information Technology, Engineering or a related field — or equivalent practical experience.

Responsibilities

• Keep our MySQL estate available, backed up, recoverable and performing across production, DR, UAT and development.
• Run day-to-day database operations: monitoring, backup and restore, patching, user access and schema changes.
• Support clustering, replication and disaster recovery setups — build them, test them and prove they fail over.
• Document configurations, backup schedules, recovery procedures and change records.
• Learn the data model behind the platform and grow into owning database environments of your own.
• Install, configure and patch MySQL, MariaDB or Percona Server on Linux.
• Manage users, roles and privileges on a least-privilege basis.
• Apply schema changes and data migrations through the change process, with a tested rollback plan.
• Monitor database health — connections, locks, slow queries, replication lag, disk and buffer pool usage — and act on what the metrics show.
• Maintain capacity forecasts covering data growth, storage headroom, archiving and purging.
• Build and support replication topologies: asynchronous and semi-synchronous, source-replica, and cluster setups such as Galera Cluster or MySQL InnoDB Cluster.
• Support managed database services where we use them — Amazon RDS and Aurora for MySQL, or Azure Database for MySQL — including parameter groups, read replicas, failover and maintenance windows.
• Configure and verify failover and take part in DR drills against agreed RTO and RPO targets.
• Keep DR databases in step with production and hold the evidence that they are.
• Run and monitor backup schedules using mysqldump, Percona XtraBackup, storage snapshots or the equivalent.
• Test restores on a regular cycle — a backup nobody has restored is not a backup.
• Maintain point-in-time recovery through binary log management and retention.
• Keep retention periods aligned to client contracts and regulatory requirements.
• Investigate slow queries using EXPLAIN, the slow query log and Performance Schema, and recommend indexing or query changes.
• Tune server configuration — buffer pool, connections, temporary tables, InnoDB settings — against measured workload rather than guesswork.
• Work with developers on data model and query design before it reaches production.
• Join incident response for database outages and degradation and write up the root cause afterwards.
• Apply database controls under our ISO/IEC 27001:2022 and PCI DSS v4.0 control environment — access control, encryption in transit and at rest, audit logging and separation of duties.
• Support periodic access reviews, vulnerability remediation and audit evidence collection.
• Handle production data, including cardholder and personal data, under our data handling and masking rules — particularly when refreshing non-production environments.

High Availability, Clustering and Disaster Recovery

• Build and support replication topologies: asynchronous and semi-synchronous, source-replica, and cluster setups such as Galera Cluster or MySQL InnoDB Cluster.
• Support managed database services where we use them — Amazon RDS and Aurora for MySQL, or Azure Database for MySQL — including parameter groups, read replicas, failover and maintenance windows.
