• Collaborate with application teams to support middleware platforms including application servers (e.g., WebLogic, Tomcat) and messaging systems (e.g., RabbitMQ, IBM MQ).
• Drive observability initiatives using tools like Dynatrace, Splunk, and Prometheus to ensure system health and performance visibility.
• Automate deployment pipelines and configuration management to support rapid development cycles and zero-downtime releases.
• Troubleshoot complex infrastructure and application issues across cloud, container, and middleware layers.
• Mentor junior engineers and contribute to DevOps best practices, governance, and documentation.
• Participate in capacity planning, disaster recovery design, and performance tuning across hybrid cloud environments.
• Stay ahead of emerging technologies in cloud, containers, and observability to continuously improve infrastructure reliability and developer experience.

Experience you’ll need to have:

• 8+ years of hands-on experience in Infrastructure as Code (IaC) using Terraform, Ansible, or similar tools.
• 5+ years of experience scripting in Python, Bash, or PowerShell for automation and tooling
• 5+ years of deep expertise in Kubernetes, container orchestration, and container lifecycle management.
• 5+ years of experience with middleware technologies such as application servers (e.g., JBoss, WebSphere) and message queues (e.g., Kafka, RabbitMQ).
• 5+ years of experience in CI/CD pipelines using tools like Jenkins, GitHub Actions, or Azure DevOps.
• 5+ years of experience in AWS and Azure cloud services, including networking, IAM, compute, and storage.
• 5+ years of experience with observability and telemetry tools like Dynatrace, Splunk, Grafana, and Prometheus.
• Bachelor's degree in a related field or an equivalent combination of education, military, and work experience.

Experience that would be great to have:

• Familiarity with security best practices, compliance standards, and infrastructure hardening.
• Excellent problem-solving skills with the ability to diagnose and resolve complex infrastructure issues.
• Strong communication and collaboration skills, with experience working in cross-functional agile teams.

How you’ll work:

• This role requires being on-call during non-standard and/or overnight hours on a rotational basis.
• This role requires the use of a computer and audio equipment.
