- Design and implement automation using Infrastructure-as-Code and Configuration Management principles (Terraform, Ansible, Consul) to ensure reproducibility, speed, and consistency in infrastructure deployment.

- Establish and maintain infrastructure standards, documentation, and architecture diagrams to support scale, reliability, and compliance across environments.

- Partner with Technical Operations, CloudOps, and Platform teams to ensure smooth integration of systems, improve deployment efficiency, and enhance observability.

- Hands-on experience with automation, configuration management, and CI/CD tools such as Terraform, Ansible, Consul, and Jenkins.

- Proficiency with observability and monitoring platforms (Grafana, ELK, VictoriaMetrics, DataDog).

- Programming experience in one or more languages such as Python, Go, or JavaScript.

- Strong understanding of infrastructure architecture principles — scalability, redundancy, fault tolerance, and cost optimization.

- Familiarity with containerization (Docker, Kubernetes) and networking fundamentals across cloud and datacenter environments.

- A proactive, analytical mindset and the ability to deliver under pressure while fostering a culture of continuous improvement and reliability.

- Excellent communication and documentation skills to facilitate alignment across cross-functional engineering teams.
