About the Role

We are looking for a DevOps Engineer (Mid–Senior level) to design, implement, and manage deployment of a highly scalable, secure, and observable platform ecosystem built on OpenShift and integrated with Vault, multiple databases, messaging middleware, and observability tools.

This platform supports mission-critical workloads and services leveraging OpenShift, HashiCorp Vault, MongoDB, PostgreSQL, MinIO, Elasticsearch, ELK Stack, Nginx, Squid, Solace, and Confluent (Kafka).

You’ll play a key role in automating infrastructure, managing CI/CD pipelines, ensuring system reliability, and enabling continuous delivery for development teams.


Key Responsibilities

  • Automate provisioning, configuration, and deployment of infrastructure and applications using Ansible, Terraform, or Helm.
  • Implement and maintain CI/CD pipelines (Jenkins) for application builds, tests, and deployments.
  • Ensure zero-downtime deployments, scalability, and resilience through automation.
  • Contribute to the standardization and automation of release processes, including branching and tagging strategies.
  • Collaborate with Digital Product teams to gather feedback, suggest improvements, and align on best practices.
  • Enforce security standards defined by integrating SAST/DAST scanning tools (SonarQube,Veracode, Trivy, Syft).
  • Maintain base UBI images and ensure regular application of security patches.
  • Set up alerting and dashboards for proactive detection and resolution of performance issues.

Security & Compliance

  • Integrate Vault with OpenShift for secrets and credential management.
  • Enforce least privilege and role-based access control (RBAC) across the platform.
  • Support vulnerability scanning, patching, and compliance automation.

Performance, Reliability & Troubleshooting

  • Analyze platform performance and implement optimization strategies for scaling.
  • Troubleshoot issues across networking, infrastructure, CI/CD, and application layers.
  • Conduct incident response and post-mortem analysis for platform outages.

Collaboration & Continuous Improvement

  • Work closely with developers, tester to support CI/CD automation, testing, and environment readiness.
  • Mentor and contribute to best practices documentation.
  • Participate in architecture discussions to ensure scalability, observability, and reliability.


Required Skills & Experience

  • 4–8 years of experience as a DevOps Engineer, SRE, or Platform Engineer.
  • Hands-on experience with OpenShift (Kubernetes) — deployments, scaling, monitoring, and troubleshooting.
  • Experience with CI/CD pipelines (Jenkins, GitLab CI, Tekton) and related automation.
  • Strong experience with Infrastructure as Code (IaC) using Terraform, Ansible, or Helm.
  • Experience managing databases (PostgreSQL, MongoDB, MinIO, Elasticsearch).
  • Familiarity with Solace, Confluent Kafka, or other message brokers.
  • Experience in monitoring/observability tools (ELK Stack, Prometheus, Grafana).
  • Proficiency in Bash, Python, or Go for scripting and automation.
  • Strong understanding of Linux system administration and networking fundamentals.


Preferred Qualifications

  • Experience with cloud platforms (Azure, AWS) integrated with OpenShift.
  • Understanding of microservices architectures and service mesh (e.g., Istio).
  • Exposure to performance testing, load balancing, and capacity planning.
  • Experience with GitOps frameworks (ArgoCD).
  • Knowledge of security best practices for cloud-native platforms.
  • Certification(s) in Kubernetes, OpenShift, or HashiCorp Vault preferred.


Soft Skills & Attributes

  • Strong analytical and problem-solving mindset.
  • Excellent communication and collaboration skills.
  • Passion for automation, continuous improvement, and reliability.
  • Ability to work in agile, fast-paced, cross-functional teams.
  • Ownership-driven and proactive in troubleshooting and optimization.
