The opportunity: We're seeking a Cloud & Platform DBA/Database Reliability Engineer to operate, optimize, and secure both managed and self-managed databases that power high-traffic eCommerce sites. You'll work primarily across AWS and GCP, while also supporting a smaller estate of hosted/on-prem databases.

Your mission: high availability, performance, security/compliance, and cost efficiency-especially during peak events.

Key Responsibilities:

• Operate managed databases (cloud):
  • AWS RDS/Aurora (MySQL/PostgreSQL), Google Cloud SQL, DynamoDB, MongoDB, DB2, Oracle.
  • Indexing, query plan analysis, schema design for OLTP, connection pool and concurrency tuning.
• Build and support self-managed databases (hosted/on-prem/VMs):
  • Oracle 19c, IBM DB2 LUW 9.5–11.5, MySQL/MariaDB, PostgreSQL, MongoDB on Linux/Unix/Windows.
  • Installation, patching, upgrades, parameter/kernel tuning, storage layout (e.g., ASM/LVM), backup/restore.
• High availability, resilience, and DR:
  • Cloud: Multi-AZ, read replicas, Aurora Global Database, cross-region replication, RDS Proxy; PITR/snapshots; tested RTO/RPO.
  • Self-managed: Oracle Data Guard (and/or RAC exposure), DB2 HADR, MySQL replication/Group Replication/XtraDB Cluster, MongoDB replica sets/sharding; RMAN, XtraBackup, db2 backup utilities.
  • Support for prod and nonprod env, which require backup and restore along with obfuscation of the sensitive data.
• Automation and change management:
  • Terraform/CloudFormation for cloud, Ansible for self-managed, GitOps workflows.
  • CI/CD for database changes (Flyway/Liquibase), standards, drift detection, automated patching, and failover.
• Observability and performance engineering:
  • CloudWatch/Cloud Monitoring, RDS Performance Insights, pg_stat_statements, MySQL Performance Schema, Oracle AWR/ASH/Statspack/OEM, DB2 MON/Explain, Datadog/New Relic/Prometheus/Grafana.
  • Capacity planning, load/soak testing for peak (e.g., BFCM), SLOs for latency/availability/throughput, post-incident reviews.
• Security, compliance, and governance:
  • IAM least privilege, secrets management (AWS Secrets Manager/HashiCorp Vault), audit logging.
  • PCI-DSS and GDPR controls, data retention/masking, change control, and approvals.
  • Cost and capacity stewardship:
    • Cloud: right-sizing instances/storage/IOPS, reserved vs on-demand/serverless choices, DynamoDB capacity modes, cost anomaly detection.
    • Self-managed: capacity forecasting and scaling plans; basic license awareness for enterprise platforms.
• Architecture collaboration:
  • Schema evolution, query patterns, caching strategies (Redis/Memcached), read/write segregation.
  • Guidance on ORM usage and connection pools; patterns for microservices and event-driven systems (Kafka/Kinesis/Pub/Sub).
• Operations and ways of working:
  • Partner with development, support, and architecture teams; maintain clear runbooks and documentation.
  • Participate in a 24/7 on-call rotation; lead incident response and preventative actions.
  • Support and plan migrations between self-managed and managed services with validation and rollback paths.

Requirements

• Hands-on production experience with managed relational databases in AWS or GCP (RDS/Aurora or Cloud SQL) using MySQL or PostgreSQL.
• Experience administering at least one self-managed enterprise RDBMS in Linux/Unix environments (Oracle or IBM DB2 LUW), or strong evidence you can ramp quickly.
• Strong performance tuning skills: execution plans, indexing strategy, slow query analysis, concurrency, and connection management.
• HA/DR expertise: replication, failover/runbooks, backups, and point-in-time recovery; setting and meeting RTO/RPO.
• Automation mindset: Terraform/CloudFormation, Ansible, CI/CD for schema changes (Flyway/Liquibase), Git; scripting in Python/Bash.
• Security/compliance fundamentals: IAM, encryption in transit/at rest, auditing; familiarity with PCI-DSS and GDPR.
• Clear communication and collaboration; ability to coach teams and document best practices.

Nice to Have

• Deep Oracle (RAC, Data Guard), DB2 HADR, or advanced PostgreSQL/MySQL internals.
• MongoDB Atlas and on-prem MongoDB (Ops Manager/backup, replica sets/sharding).
• Redis/Memcached (ElastiCache/Memorystore), Kafka/Kinesis/Pub/Sub, or Kubernetes-based app stacks.
• Exposure to analytics platforms (BigQuery/Snowflake) for operational reporting.
• Experience migrating legacy estates to managed services with minimal downtime.
• Location and ways of working: Hybrid working with regular time in our Watford office; occasional client site visits.
• Participation in an on-call/out-of-hours rotation with appropriate compensation.
