• Architect and implement Infrastructure as Code (IaC) solutions for scalable, secure, and highly available cloud environments.
• Design, deploy, optimize, and support containerized applications and microservices using Kubernetes, Docker, AWS EKS, and/or OpenShift.
• Develop advanced automation solutions using Bash, Python, Groovy, or similar scripting languages.
• Lead application and microservice deployments across development, test, staging, and production environments.
• Partner with development teams to diagnose and resolve complex application, configuration, deployment, networking, and infrastructure issues.
• Establish and promote DevOps engineering standards, automation practices, and deployment best practices.
• Identify opportunities to improve cloud scalability, resiliency, security, automation, performance, and operational efficiency.
• Evaluate and implement emerging DevOps, cloud-native, containerization, and automation technologies.
• Provide technical guidance and mentorship to junior and mid-level DevOps engineers.

• Ensure the availability, reliability, scalability, and performance of 24x7 production and non-production environments.
• Lead technical response and troubleshooting efforts during complex production incidents and outages.
• Perform and facilitate root cause analysis (RCA) and develop corrective and preventative actions.
• Design and improve monitoring, alerting, logging, and observability capabilities across cloud and application environments.
• Analyze application, infrastructure, network, and system performance to proactively identify reliability and capacity issues.
• Define and track operational KPIs related to availability, uptime, SLA performance, incidents, capacity, and system health.
• Lead or oversee operational maintenance activities including operating system patching, security remediation, vulnerability management, and environment upgrades.
• Improve system observability through dashboards, metrics, alerts, distributed logging, and application performance monitoring.
• Participate in an on-call rotation and provide senior-level technical support during critical production incidents, deployments, outages, and service transitions.
• Identify recurring operational issues and develop automation and engineering solutions that reduce manual intervention.

• 7+ years of relevant DevOps, Cloud Engineering, Site Reliability Engineering, Systems Engineering, or related experience.
• Advanced hands-on experience designing and maintaining enterprise CI/CD pipelines, preferably using Jenkins and Groovy.
• Strong hands-on experience with Kubernetes, Docker, AWS EKS, and/or OpenShift.
• Strong understanding of microservices architecture, distributed systems, and container-based application environments.
• Advanced experience with Infrastructure as Code, using technologies such as Terraform, CloudFormation, or similar platforms.
• Strong scripting and automation experience using Bash, Python, Groovy, or similar languages.
• Extensive hands-on experience with AWS services including VPC, EC2, EKS, RDS, IAM, CloudWatch, and related cloud technologies.
• Experience designing and supporting highly available, scalable, and secure AWS cloud environments.
• Strong experience with monitoring, logging, observability, and application performance platforms such as AWS CloudWatch, New Relic, Splunk, or similar tools.
• Strong experience with source code and version control systems such as Git.
• Experience supporting and troubleshooting Java and/or Node.js web applications, including technologies such as Spring Boot and React.
• Advanced troubleshooting skills across applications, cloud infrastructure, networking, containers, CI/CD pipelines, and production environments.
• Strong understanding of incident management, problem management, change management, SLAs, production support, and root cause analysis.
• Demonstrated ability to independently solve complex technical problems and drive issues through resolution.
• Experience mentoring engineers and contributing to technical standards and engineering best practices.
• Excellent analytical, troubleshooting, communication, and collaboration skills.
•
