Description:

Our client is seeking a minimum of two experienced Senior Infrastructure Engineers with extensive expertise in PostgreSQL database administration, infrastructure automation and enterprise database management.

The successful candidates will be responsible for implementing, managing and optimising enterprise infrastructure and database environments that support digital services. The roles require advanced technical capabilities across PostgreSQL, EnterpriseDB (EDB), Red Hat Enterprise Linux (RHEL), OpenShift, VMware and contemporary DevOps technologies.

Working with a high degree of independence, the successful candidates will design, deploy and maintain highly available, secure and reliable database solutions while supporting infrastructure automation, database migrations, performance optimisation and disaster recovery.

The positions also involve troubleshooting complex production incidents, maintaining operational stability and contributing to continuous improvement initiatives.

Occasional out-of-hours work may be required to complete scheduled activities or resolve complex incidents.

Responsibilities:

  • Configure, manage and maintain High Availability and Disaster Recovery (HADR) replication clusters using EDB Failover Manager (EFM).
  • Install, configure and administer EDB Postgres Enterprise Manager (PEM), including agent deployment, database registration and performance monitoring.
  • Develop and maintain Infrastructure-as-Code (IaC) solutions for PostgreSQL deployments.
  • Design, deploy and maintain PostgreSQL environments using Ansible and CI/CD pipelines across RHEL, OpenShift and VMware platforms.
  • Configure Argo CD deployments and integrate GitOps workflows with GitLab.
  • Develop Python and Shell scripts to automate database administration, monitoring, deployments and operational processes.
  • Implement backup and disaster recovery strategies, including automated backup orchestration, point-in-time recovery (PITR), WAL archiving and replication-based recovery.
  • Plan and execute database migrations using logical and physical replication, WAL shipping, backup and restore, database cloning and server-level migration techniques.
  • Evaluate and select appropriate database migration approaches based on compatibility, downtime, data integrity, performance, rollback requirements and business continuity.
  • Configure and maintain PostgreSQL authentication and security controls, including LDAP/Active Directory integration, role-based access control (RBAC), TLS encryption and X.509 certificates.
  • Manage database software installations, upgrades and version migrations to maintain platform currency.
  • Monitor and optimise database performance, availability, capacity and operational compliance across production environments.
  • Troubleshoot complex database and operating system incidents, undertake root-cause analysis and implement remediation strategies.
  • Contribute to technical documentation, knowledge sharing and team capability uplift.

Requirements:

  • Minimum five years of PostgreSQL database administration experience in enterprise environments.
  • Extensive experience managing PostgreSQL high availability, replication, automated backups, disaster recovery and performance optimisation.
  • Demonstrated experience with EDB Postgres Enterprise Manager (PEM), including monitoring, query analysis, diagnostics and alerting.
  • Experience designing, deploying and maintaining PostgreSQL solutions using Ansible CI/CD pipelines across RHEL, OpenShift and VMware environments.
  • Demonstrated experience developing and maintaining Infrastructure-as-Code (IaC) solutions.
  • Strong knowledge of PostgreSQL version upgrades, database migration methodologies and cross-platform migrations.
  • Experience implementing PostgreSQL database security controls, including LDAP/Active Directory authentication, RBAC, TLS encryption and certificate management.
  • Proficiency in Python and Shell scripting for database administration and operational automation.
  • Experience implementing GitOps deployment workflows using Argo CD and GitLab.
  • Strong troubleshooting and analytical skills, including complex production incident management and root-cause analysis.
  • Ability to work independently, manage technical priorities and maintain operational documentation.

Key Capabilities:

  • PostgreSQL Database Administration: Advanced expertise in administering, maintaining and optimising enterprise PostgreSQL database environments.
  • High Availability and Disaster Recovery: Strong capabilities in database replication, automated backup, point-in-time recovery, failover management and business continuity.
  • Infrastructure Automation: Experience developing and maintaining Infrastructure-as-Code using Ansible, CI/CD pipelines and scripting technologies.
  • EnterpriseDB Administration: Expertise in EDB Postgres Enterprise Manager and EDB Failover Manager for database monitoring, diagnostics and high availability.
  • Cloud and Virtual Infrastructure: Technical expertise across RHEL, OpenShift and VMware environments.
  • Database Migration and Upgrades: Ability to plan and execute complex PostgreSQL migrations, version upgrades and platform transitions.
  • Database Security: Strong understanding of authentication, access management, encryption, certificate management and enterprise security standards.
  • DevOps and GitOps: Experience implementing automated deployment workflows using Argo CD, GitLab, Python and Shell scripting.
  • Performance Optimisation: Advanced troubleshooting, query analysis, performance diagnostics and capacity management skills.
  • Incident Management: Ability to resolve complex production incidents, conduct root-cause analysis and implement resilient remediation strategies.

Essential Criteria:

  • Minimum five years’ PostgreSQL database administration experience
  • Experience designing, deploying and maintaining PostgreSQL deployments using Ansible CI/CD pipelines in RHEL OpenShift and VMware environments
  • Experience developing and maintaining infrastructure-as-code
  • Experience optimising PostgreSQL database integration and performance
