DevOps Engineer

Key Responsibilities

• Take full ownership of the migration process to AWS, including planning and execution.
• Work closely with architects to define the best approach for migrating applications into Amazon EKS.
• Mentor and guide a team of DevOps Engineers, assigning tasks and ensuring quality execution.
• Design and implement CI/CD pipelines using Jenkins, with an emphasis on security, maintainability, and scalability.
• Integrate static and dynamic code analysis tools (e.g., SonarQube) into the CI/CD process.
• Manage secure access to AWS services using IAM roles, least privilege principles, and container-based identity (e.g., workload identity).
• Create and manage Helm charts for Kubernetes deployments across multiple environments.
• Conduct data migrations between S3 buckets, PostgreSQL databases, and other data stores, ensuring data integrity and minimal downtime.
• Troubleshoot and resolve infrastructure and deployment issues, both in local containers and Kubernetes clusters.
  

Required Skills & Expertise

• Jenkins pipelines (DSL), SonarQube, Nexus or Artifactory
• Shell scripting, Python (with YAML/JSON handling)
• Git and version control best practices
  

Containers & Kubernetes

• Docker (multi-stage builds, non-root containers, troubleshooting)
• Kubernetes (services, ingress, service accounts, RBAC, DNS, Helm)
  

Cloud Infrastructure (AWS)

• AWS services: EC2, EKS, S3, IAM, Secrets Manager, Route 53, WAF, KMS, RDS, VPC, Load Balancers
• Experience with IAM roles, workload identities, and secure AWS access patterns
• Network fundamentals: subnets, security groups, NAT, TLS/SSL, CA certificates, DNS routing
  

Databases

• PostgreSQL: pg_dump/pg_restore, user management, RDS troubleshooting
  

Web & Security Concepts

• NGINX, web servers, reverse proxies, path-based/host-based routing
• Session handling, load balancing (stateful vs stateless)
• Security best practices, OWASP Top 10, WAF (configuration/training), network-level security, RBAC, IAM policies
  

Candidate Expectations

• Explain best practices around CI/CD pipeline design and secure AWS integrations.
• Demonstrate complex scripting solutions and data processing tasks in Bash and Python.
• Describe container lifecycle, troubleshooting steps, and security hardening practices.
• Detail Kubernetes architecture, Helm chart design, and access control configurations.
• Show a deep understanding of AWS IAM, networking, service integrations, and cost-conscious design.
• Discuss TLS certificate lifecycle, trusted CA usage, and implementation in cloud-native environments.
  

Preferred Qualifications

• AWS Certified DevOps Engineer or equivalent certifications.
• Experience in FinTech, SaaS, or other regulated industries.
• Knowledge of cost optimization strategies in cloud environments.
• Familiarity with Agile/Scrum methodologies.
• Certifications or experience with ITIL or ISO 20000 frameworks are advantageous.
