DevOps Engineer

JOB Description

About the Role

We are looking for a Senior DevOps Engineer with strong hands-on experience in building, operating, and continuously improving production infrastructure on AWS. The ideal candidate will have genuine ownership of production environments and should be comfortable working across cloud infrastructure, Kubernetes, infrastructure-as-code, CI/CD, observability, security, and automation.

The role will involve designing and maintaining reliable, scalable, and secure infrastructure, while enabling efficient and consistent software delivery through Terraform, Kubernetes, Helm, GitOps, and CI/CD automation.

The candidate should be a strong problem solver who can independently troubleshoot production issues, understand infrastructure dependencies, and automate repetitive operational activities using Python or Bash.

Key Responsibilities

• Own and operate production infrastructure on AWS, ensuring reliability, availability, scalability, and performance.
• Design, provision, and manage cloud infrastructure using Terraform, including reusable modules, state management, imports, and infrastructure changes.
• Review Terraform plans carefully and assess the potential impact of infrastructure changes before implementation.
• Manage and operate production Kubernetes environments, including cluster upgrades, ingress, RBAC, resource limits, workload troubleshooting, and operational maintenance.
• Develop, maintain, and troubleshoot Helm charts for application deployment and configuration management.
• Implement and maintain GitOps / declarative delivery practices using tools such as ArgoCD, Flux, or equivalent platforms.
• Design, maintain, and improve CI/CD pipelines, preferably using GitHub Actions, to enable reliable and repeatable software delivery.
• Troubleshoot Linux systems, networking issues, application deployments, containers, and infrastructure-related production incidents.
• Work closely with engineering and application teams to understand infrastructure requirements and ensure smooth deployment and operation of services.
• Develop automation scripts using Python and/or Bash to eliminate repetitive operational tasks and improve engineering efficiency.
• Monitor system health, performance, availability, and reliability and proactively identify potential production issues.
• Contribute to infrastructure security, access management, secrets management, and operational hardening.
• Participate in incident investigation, root-cause analysis, and implementation of preventive measures.
• Continuously evaluate infrastructure cost, capacity, scalability, and operational efficiency.
  
  

Key Deliverables

• Stable, scalable, and highly reliable AWS production infrastructure.
• Infrastructure managed through Terraform and declarative configuration practices.
• Well-maintained and production-ready Kubernetes clusters and workloads.
• Standardized and reusable Helm charts for application deployments.
• Reliable GitOps-based deployment workflows with appropriate controls and traceability.
• Efficient and maintainable CI/CD pipelines supporting frequent and reliable releases.
• Effective monitoring, alerting, troubleshooting, and incident-resolution practices.
• Automation of repetitive operational activities through Python/Bash scripting.
• Improved infrastructure security, access control, and operational resilience.
• Continuous optimization of cloud cost, capacity, performance, and reliability.
  
  

Qualifications

• Bachelor's degree in Computer Science, Information Technology, Engineering, or a related technical discipline.
• 3+ years of hands-on experience managing production infrastructure, preferably on AWS.
