Backend Engineer - Qlik Replicate,Middleware / Product Installation,Configuration
Summary
Backend engineer installs, configures, and maintains Qlik Replicate and other CDC middleware, onboards source systems, and automates pipelines using AWS, Terraform, and CI/CD tools.
Experience and Skills Required
Middleware / Product Installation &Configuration:
- Degree or Diploma in Computer Science, Computer or Electronics Engineering, Information Technology, or related disciplines.
- Hands‑on experience installing, configuring, and maintaining middleware or data replication products (QlikReplicate, IBM InfoSphere DataStage/CDC, Oracle GoldenGate, Debezium, or similar) in an enterprise environment.
- Practical experience onboarding new source systems into a CDC platform, including endpoint configuration, initial full-load, and incremental change capture setup.
- Working knowledge of source database technologies commonly paired with CDC middleware (e.g. DB2, VSAM, Oracle, SQL Server, MySQL, PostgreSQL).
- Familiarity with message broker/streaming integration (Kafka, AWS MSK) as a CDC target or intermediary layer.
Cloud Knowledge:
- Hands‑on experience with AWS core services relevant to CDC architectures (EC2, MSK, RDS, DynamoDB, S3, IAM,VPC/networking).
- Understanding of hybrid connectivity patterns between on‑premise mainframe/data center environments and cloud target environments (VPN, Direct Connect, Transit Gateway).
- Familiarity with cloud security fundamentals: IAM least‑privilege design, secrets management, encryption in transit and at rest.
- Exposure to Azure or Google Cloud is an advantage but not required, given the AWS‑centric target environment.
DevSecOps & Automation (Preferred):
- Experience with Infrastructure as Code tools, particularly Terraform, for provisioning and supporting cloud resources.
- Experience with CI/CD pipelines(GitHub Actions, GitLab CI, Jenkins, ArgoCD) to automate configuration deployment and change management for replication tasks.
- Familiarity with configuration management and scripting (Bash, Python, PowerShell, Ansible) to automate repetitive onboarding and maintenance tasks.
- Understanding of security best practices for CI/CD pipelines and secrets management (HashiCorp Vault, AWS Secrets Manager).
- Experience with monitoring and observability tooling (CloudWatch, Prometheus, Grafana, ELK stack) to build dashboards and alerts for replication health.
- Experience with Git and modern branching workflows for managing configuration-as-code and documentation.
