About the Role
System Engineer (Networking & Security)
We are looking for a System Engineer (Networking & Security) who will own the design, automation, and operation of our on-prem networking and security infrastructure. This role is part of our DevOps team and follows the same principles we apply to our cloud platform: Infrastructure as Code, observability, and collaboration.
You will ensure our office and datacenter network stack (UniFi, FortiGate, Wazuh) is secure, scalable, and seamlessly integrated with our existing DevOps workflows.
Responsibilities
- Design, implement, and automate network configurations (VLANs, WiFi policies, firewall rules) using IaC tools such as Terraform and Ansible
- Manage UniFi switches, Dream Machine Pro, and enterprise WiFi setups (WPA3-Enterprise, RADIUS)
- Configure and maintain FortiGate firewalls including VPNs, network segmentation, and security policies
- Integrate network monitoring with the existing observability stack (Prometheus, Wazuh, Grafana)
- Collaborate with cloud DevOps engineers to enable seamless hybrid connectivity (Cloud VPN, HA VPN, Interconnect)
- Take full ownership of issues end-to-end, working cross-functionally with developers, security, and DevOps teams
- Document network topologies, policies, and changes in version-controlled repositories
What We Value
- Automation-first mindset – eliminate manual configuration drift by codifying changes
- Strong collaboration – work openly with developers and cross-functional teams
- Ownership mentality – fix root causes, prevent recurrence, and improve processes
- Continuous improvement – enhance observability, security, and resilience
Skills & Experience
- Proven experience with enterprise networking (LAN/WAN, VLANs, Fortinet firewalls, UniFi stack)
- Hands-on experience with automation tools (Terraform, Ansible, Python/Bash)
- Familiarity with SIEM/IDS solutions (Wazuh / ELK stack) and alert integration
- Solid understanding of hybrid cloud networking (VPNs, routing, BGP)
- 3–5+ years of experience in network/security engineering with DevOps exposure
