Operations Engineer

Project Role : Operations Engineer Project Role Description : Support the operations and/or manage delivery for production systems and services based on operational requirements and service agreement. Must have skills : IBM WebSphere Application Server Application Deployment, API Gateway, Middleware Good to have skills : NA Minimum 12 year(s) of experience is required Educational Qualification : 15 years full time education Summary: A Principal Engineer — Database & Middleware leads the hands-on design, build, and operation of enterprise data and integration platforms across relational databases (Oracle, SQL Server, PostgreSQL), NoSQL stores (MongoDB), cloud-native database services (AWS RDS/Aurora, GCP Cloud SQL, Azure Cosmos DB), and the full middleware stack — IBM WAS, IBM IHS, Tomcat, Apache HTTP Server, SiteMinder, IBM MQ, Rabbit MQ, MuleSoft, Ansible etc. At, this individual operates as a recognized domain authority — engineering production-grade data and integration platforms, driving automation and observability, and owning reliability outcomes end to end. In a financial services context, every platform decision must satisfy PCI DSS, SOX, DORA, and data residency requirements while meeting the availability and latency demands of mission-critical business services. Roles & Responsibilities: Database Platform Engineering – Design, build, and operate enterprise relational database platforms — Oracle (RAC, Data Guard, ASM), SQL Server (AlwaysOn, SSAS, SSIS), and PostgreSQL — across on-premises and cloud environments – Engineer and maintain cloud-native database services — AWS RDS/Aurora, GCP Cloud SQL/Spanner, and Azure Cosmos DB — including provisioning, HA configuration, replication, and automated failover – Implement and operate MongoDB replica sets and sharded clusters for high-throughput, low-latency FSI workloads – Build and maintain database automation — IaC provisioning (Terraform), schema migration pipelines, backup/restore validation, and patching automation – Design and implement database high availability, disaster recovery, and business continuity architectures — meeting RTO/RPO commitments for Tier 1 FSI workloads – Engineer database performance — query optimisation, index strategy, execution plan analysis, wait event diagnosis, and capacity right-sizing across all platforms – Implement and maintain database security controls — TDE, column-level encryption, RBAC, auditing, and data masking — aligned to PCI DSS and SOX requirements – Drive database observability — metrics collection, slow query alerting, replication lag monitoring, and capacity trending across on-premises and cloud estates Middleware & Integration Platform Engineering – Engineer and operate IBM MQ and RabbitMQ messaging infrastructure — queue manager configuration, channel security, HA clustering, and dead-letter queue management – Design and build IBM WAS, IBM IHS, Tomcat, Apache HTTP Server platforms — broker cluster operations, topic design, partition strategy, consumer group management, Schema Registry, and Kafka Connect pipelines – Engineer CA SiteMinder Authentication platform and adapter configuration, process orchestration, HA deployment, and performance tuning – Design and operate enterprise API Gateway infrastructure — IBM WAS, IBM IHS, Tomcat, Apache HTTP Server – Istio or Linked — for microservices traffic management, mTLS enforcement, observability, and circuit breaking – Build CI/CD and GitOps pipelines for middleware platform configuration, integration flow deployment, and schema lifecycle management – Drive integration platform observability — distributed tracing, message throughput dashboards, error rate alerting, and end-to-end latency analysis across the integration stack Technical Leadership & Engineering Excellence – Set platform engineering standards, reference patterns, and IaC module libraries for database and middleware platforms — codified and reusable across teams – Conduct production readiness reviews and technical design assessments for data and integration workstreams – Lead proof-of-concept engineering for emerging database and integration technologies — delivering evidence-based build-vs-buy recommendations – Mentor senior and mid-level engineers in database internals, integration patterns, and production operations – Drive continuous improvement — reducing toil through automation, improving platform reliability, and eliminating technical debt across the data and middleware estate – Support audit, regulatory, and risk management activities — producing platform configuration evidence, data lineage documentation, and compliance reports Professional & Technical Skills: Must-Have Technical Skills Oracle Engineering: RAC, Data Guard, ASM, RMAN — performance tuning, AWR/ASH analysis, schema design, and HA/DR implementation at enterprise scale SQL Server Engineering: AlwaysOn AG, SSAS, SSIS, SSRS — query tuning, execution plans, index optimisation, and HA configuration for FSI workloads PostgreSQL: Streaming replication, logical replication, partitioning, VACUUM tuning, pg stat analysis, and extensions (TimescaleDB, PostGIS, Citus) MongoDB: Replica set and sharded cluster operations, aggregation pipeline optimisation, index strategy, Atlas operations, and change stream engineering Cloud DB Services: AWS RDS/Aurora (MySQL, PostgreSQL, Oracle), GCP Cloud SQL/Spanner, Azure Cosmos DB — provisioning, HA, replication, and cost optimisation CA SiteMinder: Authentication platform and adapter configuration, process orchestration, HA deployment, and performance tuning App/Web Services: Design, Installation, configure, monitor and troubleshooting of IBM WAS, Weblogic, JBoss, Tomcat, IBM IHS, Apache IBM MQ: MQ queue manager HA clustering, channel security, dead-letter handling adapter configuration, and performance tuning IaC & Automation: Terraform / Ansible / Jenkins for database and middleware provisioning, Ansible for configuration management, and CI/CD pipelines for sc
