Job Description

About the Role:

We are seeking a DevOps Engineer to lead the migration of multiple applications and services into a new AWS environment. This role requires a strategic thinker with hands-on technical expertise, a deep understanding of DevOps best practices, and the ability to guide and mentor other engineers. You will work closely with architects and technical leads to design, plan, and execute cloud-native solutions with a strong emphasis on automation, scalability, security, and performance.

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

CI/CD & DevOps Tools:

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

Containers & Kubernetes

Web & Security Concepts

- NGINX, web servers, reverse proxies, path-based/host-based routing

- Security best practices, OWASP Top 10, WAF (configuration/training), network-level security, RBAC, IAM policies

Candidate Expectations

The ideal candidate should be able to:

- 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.
