System Administrator

We are looking for an enthusiastic, collaborative, and highly motivated hands-on System Administrator with a DevOps mindset to join our infrastructure team and help build and maintain our customer-facing production environments, keeping them secure, monitored, and highly available.

This is not only a maintenance role. Together with the team you will stand up complete cloud and on-prem environments, configure network security, automate recurring operational work, and document it so the rest of the team can repeat it. We are looking for someone who takes ownership, wants to understand the full picture, is naturally curious and self-learning, and works independently and methodically, driving production issues to root cause rather than to a workaround.

Job description:

As part of the infrastructure team, build new customer environments from scratch and maintain them ongoing, in cloud (AWS / Azure) and on-prem: compute, networking, storage, load balancers, DNS, certificates, Active Directory, and application deployment

Own network security on Fortinet (FortiGate): security policies, NAT, routing, IPSec/SSL VPN tunnels, HA pairs, and FortiAuthenticator / FortiClient EMS

Manage Active Directory across all customer environments: user accounts, security groups, group policies, permissions, and access control

Maintain on-prem infrastructure: VMware / ESXi virtualization, backup and recovery, storage systems, and ongoing server maintenance, including Windows Server updates, patching, reboots, and health checks

Build and maintain monitoring and alerting, and handle the full lifecycle of SSL/TLS certificates across environments

Configure and maintain load balancers (HAProxy, Azure Application Gateway, Fortinet), DNS records, and firewall rules for proper access control and security compliance

Automate recurring operational work using scripting (PowerShell / Bash) and CI/CD tooling (Git, Jenkins)

Take part in periodic DR and site failover testing together with the team

Standardize IT processes, improve operational consistency across regions, and document recurring tasks and create runbooks so processes are repeatable and auditable
