This role is responsible for building and maintaining highly available network systems that support mission-critical data center operations.
This is a hands-on technical role at the intersection of network engineering and reliability operations, in a complex environment where uptime is non-negotiable.
Key Responsibilities
Network Operations & Reliability
* Design, implement, and maintain reliable and scalable LAN/WAN and data center network infrastructure.
* Monitor network performance, latency, and capacity — ensuring high availability and proactive fault detection.
* Troubleshoot and resolve network incidents quickly, coordinating with vendors and internal teams.
* Drive root-cause analysis (RCA) and implement preventive measures for recurring issues.
* Maintain and enhance network monitoring, alerting, and automation systems.
Architecture & Deployment
* Support the design and rollout of connectivity solutions for new data center builds and expansions.
* Work with the Head of ICT to develop network architecture standards, documentation, and deployment playbooks.
* Evaluate and implement new technologies to improve scalability, security, and resilience.
* Participate in change management, ensuring network updates are tested and deployed with minimal disruption.
Automation & Continuous Improvement
* Develop scripts and tools (Python, Ansible, etc.) to automate network configuration, testing, and monitoring tasks.
* Identify opportunities to improve reliability, reduce manual effort, and streamline operations.
* Contribute to building a "network as code" culture with repeatable, testable infrastructure deployments.
Cross-functional Collaboration
* Partner with Data Center Operations, Cloud, End User and Infrastructure teams to ensure seamless connectivity between systems.
* Collaborate with external carriers, ISPs, and partners on peering and interconnection projects.
* Support connectivity design for client onboarding and bespoke networking solutions.
Requirements
* Bachelor's degree in Network Engineering, Computer Science, Telecommunications, or equivalent practical experience.
* 5+ years of experience in network engineering, with a focus on reliability, high availability, or data center environments.
* Strong understanding of routing and switching protocols (BGP, OSPF, MPLS, VXLAN, EVPN).
* Experience with network automation tools (Ansible, Terraform, Python scripting).
* Proficiency with network monitoring systems (SolarWinds, NetBox, Prometheus, Grafana, etc.).
* Deep familiarity with layer 2 and layer 3 troubleshooting, redundancy mechanisms, and high-performance networking concepts.
* Fluency in English and Portuguese.
* Experience with carrier-grade connectivity, Internet exchanges, or fiber network operations.
