Senior Platform Engineer - Git Lab Cloud Migration Lead

About the Project
This is a strategic initiative to modernize our build and deploy infrastructure by migrating from on-premises Git Lab to Git Lab Cloud. The role involves complex, interdependent infrastructure challenges spanning CI/CD pipelines, Kubernetes orchestration, web application performance optimization, and observability implementation. You'll work on systems that require both technical depth and collaborative problem-solving skills.

Key Responsibilities
Lead and architect the complete migration strategy for Git Lab and Helm infrastructure from on-premises to Git Lab Cloud
Design and implement robust CI/CD pipeline architectures optimized for Git Lab Cloud execution
Establish Git Lab Runner infrastructure with autoscaling capabilities and cost optimization
Architect and maintain Kubernetes cluster management using Rancher
Design and optimize web application infrastructure including:
HTTP/HTTPS protocols, load balancers, and reverse proxies
SQL database performance tuning and high availability configurations
WAF implementation and security policies (Fastly or equivalent)
Caching strategies using CDN providers (Fastly preferred)
Drive comprehensive observability strategy using Loki & Grafana for metrics, logs, and distributed tracing
Implement security best practices including WAF rules, DDoS protection, and access controls
Establish infrastructure as code practices and disaster recovery procedures
Conduct capacity planning and performance optimization for build/deploy infrastructure and application layer

Required Skills
4-5+ years of experience in Dev Ops, Platform Engineering, or Site Reliability Engineering

Experience with setting up & maintaining an on-prem Kubernetes environment is a must.
