Description :

Role : Senior Platform Engineer GitLab Cloud Migration Lead.

About the Project :

This is a strategic initiative to modernize our build and deploy infrastructure by migrating from on-premises GitLab to GitLab 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 GitLab and Helm infrastructure from on-premises to GitLab Cloud.

- Design and implement robust CI/CD pipeline architectures optimized for GitLab Cloud execution.

- Establish GitLab Runner infrastructure with autoscaling capabilities and cost optimization.

- Architect and maintain Kubernetes cluster management using Rancher.

Design and optimize web application infrastructure including :

1. HTTP/HTTPS protocols, load balancers, and reverse proxies.

2. 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 DevOps, Platform Engineering, or Site Reliability Engineering.

- Expert-level Linux systems administration and troubleshooting with Red Hat Enterprise Linux (RHEL) and/or SUSE Linux Enterprise Server (SLES).

- Advanced knowledge of systemd, SELinux/AppArmor.

- Performance tuning and kernel parameter optimization.

- Storage management (LVM, filesystems).

- Network configuration and troubleshooting.

Deep expertise in GitLab administration including :

1.GitLab migration tools and procedures.

2. GitLab API for automation.

3. Runner configuration and optimization.

4. GitLab Cloud (SaaS) architecture and limitations.

- Advanced Kubernetes knowledge with production experience managing multiple clusters.

- Production experience with Rancher for Kubernetes orchestration and management.

- Comprehensive web application infrastructure expertise :

- Deep understanding of HTTP/HTTPS protocols, TLS/SSL, and web security.

- Advanced SQL database administration (MySQL, PostgreSQL) including replication, backup/recovery.

- WAF configuration and management (Fastly WAF experience highly preferred).

- Caching provider expertise (Fastly, Cloudflare, or Akamai) for performance optimization.

- Strong proficiency in GoLang, Python, and Bash for building tools and automation.

- Observability expertise with Loki & Grafana :

- Log aggregation and analysis with Loki.

- Dashboard creation and alerting with Grafana.

- Metrics collection and visualization.

Extensive AWS administration experience including :

- Compute : EC2, EKS, Auto Scaling.

- Storage : S3, EBS, EFS.

- Database : RDS, Aurora.

- Network : VPC, Route53, CloudFront, ALB/NLB.

- Security : IAM, Security Groups, KMS, Secrets Manager.

- Proven track record of successful large-scale cloud migration projects.

Primary Focus Areas :

- GitLab Cloud Migration Moving repositories, CI/CD pipelines, Helm charts, and container registries.

- Build & Deploy Pipelines Optimizing GitLab CI/CD and Helm deployments for cloud execution.

- Web Application Infrastructure Managing HTTP protocols, SQL databases, WAF (Fastly), and caching layers.

- Kubernetes & Rancher Container orchestration and cluster management.

- Observability Implementing Loki & Grafana for comprehensive monitoring and logging.

- AWS Administration Cloud infrastructure management and optimization.

- Enterprise Linux Management Red Hat or SUSE Linux systems administration.
