Job description

Job Summary:

We are seeking a highly capable and hands-on DevOps Engineer / DevOps Consultant to support critical cloud engineering, platform operations, and migration initiatives within a complex enterprise environment. This contract role requires a self-driven professional who can operate independently, take ownership of deliverables, and execute with minimal supervision while collaborating effectively across infrastructure, security, networking, and application teams.

The successful candidate will be responsible for designing, implementing, maintaining, and migrating secure, scalable, and highly available cloud infrastructure and deployment pipelines, with deep expertise in AWS, Terraform, CI/CD, containerization, Linux administration, networking, security integration, and observability platforms.

A key focus of this role will be to lead and support enterprise migration activities, including:

• AWS tenant migration from Org A to Org B
• Observability migration from Splunk to Google Observability and Google SecOps
• Complex network and security infrastructure changes, including Route 53, SSL/TLS certificate changes, Transit Gateway (TGW) updates, DNS server changes, Zscaler changes, and WAF changes
• Governance and security policy updates, including SCP (Service Control Policy) changes
• The ideal candidate will demonstrate strong technical depth, sound engineering judgment, and a commitment to security by design, shift-left engineering, cost optimization, standardization, and operational excellence.

Key Responsibilities:

• Design, deploy, and manage secure, scalable, and resilient cloud infrastructure using AWS services.
• Take a hands-on role in the implementation, troubleshooting, and optimization of infrastructure, automation, deployment pipelines, and production support activities.
• Lead and support AWS tenant migration activities, including the movement of infrastructure, services, configurations, and dependencies from Org A to Org B.
• Plan and execute migration tasks with strong attention to service continuity, dependency mapping, risk mitigation, rollback planning, and post-migration stabilization.
• Support the migration of observability and security monitoring platforms from Splunk to Google Observability and Google SecOps, including log routing, monitoring integration, alerting considerations, and operational transition.
• Design and execute complex network infrastructure changes, including:
• Route 53 updates and DNS cutover activities
• SSL/TLS and certificate changes
• Transit Gateway (TGW) changes
• DNS server changes
• Zscaler-related updates
• WAF configuration changes
• Implement and manage SCP (Service Control Policy) changes in alignment with organizational governance, security, and access control requirements.
• Architect and implement AWS networking solutions, including VPC, NAT Gateway, Transit Gateway, Route Tables, Route 53, Resolvers, and DNS configurations.
• Manage and optimize AWS services such as ACM, CloudFront, API Gateway, Athena, ECS, Lambda, Step Functions, and AWS Glue.
• Manage storage and data platform components, including EBS, RDS, MongoDB, Snowflake, and S3 / S3 Tables.
• Develop and maintain infrastructure as code using Terraform, with emphasis on modularity, reusability, governance, and compliance with engineering standards.
• Build, optimize, and troubleshoot GitLab CI/CD pipelines for automated build, testing, and deployment.
• Containerize applications using Docker and support deployment in containerized environments.
• Administer Linux-based systems, including system configuration, operational support, performance tuning, and troubleshooting.
• Automate operational and deployment activities using shell scripting and related scripting techniques.
• Collaborate with security teams to integrate security controls, vulnerability management, and policy enforcement into engineering workflows.
• Identify and implement cost-saving opportunities without compromising security, performance, or reliability.
• Standardize infrastructure modules, deployment patterns, and operating procedures to improve consistency and maintainability.
• Produce clear and accurate documentation covering architecture, migration runbooks, implementation procedures, operational workflows, and support handover materials.
• Work closely with cross-functional teams to improve platform maturity, reliability, migration readiness, and delivery efficiency.
• Act as a dependable technical contributor who can independently drive workstreams, resolve issues proactively, and elevate risks appropriately.
