Infrastructure Systems Engineer

We are seeking a skilled Systems Engineer who enjoys hands-on work with infrastructure, servers, and network devices.

In this role, you will be a key part of keeping our data center running smoothly — configuring modems, switches, and Cisco routers, monitoring system health, automating data flows, deploying new hardware, and resolving technical issues.

• Configure, validate, and deploy network devices (modems, switches, Cisco routers), including new hardware setup, troubleshooting, and functionality testing.
• Support and improve infrastructure tooling — including automation, data-flow testing, and custom solutions.
• Monitor system health using tools such as Zabbix and Grafana, tracking alerts, performance, temperature, and device status across 3000+ connected units.
• Collaborate with fellow systems engineers to optimize and evolve the infrastructure.
• Perform additional duties assigned by Digital management as needed.
