Job Title- Senior DevOps Engineer
Location- Pune | Hybrid
Experience- 6-8 Years
Primary Skills- Linux Programming, AWS, Terraform/OpenTofu, Cloud Migration, DevOps/SRE
Focus Area- AI-Driven Infrastructure Modernization

ABOUT THE ROLE

We are hiring a Senior Cloud Platform / DevOps / SRE Engineer to help migrate, modernize, operate, and improve infrastructure across a portfolio of businesses. This role will focus first on AWS, with future expansion into Azure and GCP.

The ideal candidate has experience moving legacy infrastructure from colo, hosted, data center, or existing cloud environments into AWS. This includes both colo-to-cloud and cloud-to-cloud migrations. Early work may include lift-and-shift migrations; over time, this role will help standardize, automate, secure, observe, and modernize those environments.

This is also a production reliability role, requiring support for production uptime, incident response, escalation processes, and reliable infrastructure and deployment practices.

This is an AI-first infrastructure role. The ideal candidate should use AI tools to accelerate infrastructure analysis, Terraform/OpenTofu development, migration planning, CI/CD improvement, troubleshooting, documentation, automation, and operational remediation.

ROLES AND RESPONSIBILITIES

Lead and support migrations from colo, hosted, legacy, and existing cloud environments into AWS.

Assess current-state infrastructure, document dependencies, identify risks, and create migration, cutover, rollback, and validation plans.

Map source environments including networking, IAM, storage, databases, DNS, certificates, security controls, observability, and deployment workflows into appropriate AWS target architectures.

Support both colo-to-cloud and cloud-to-cloud migrations.

Help determine whether applications should be lift-and-shifted, containerized, re-platformed, or more deeply modernized.

Build, maintain, and standardize cloud infrastructure using Terraform or OpenTofu.

Operate and improve multi-account AWS environments using AWS Organizations and related governance patterns.

Help establish a centralized cloud operating model across AWS, with a path toward Azure and GCP.

Design and support cloud networking, IAM, security, logging, monitoring, backups, disaster recovery, and high-availability solutions.

Define best practices for infrastructure automation, CI/CD, observability, reliability, security, and cloud operations.
