Network Engineer

What You Will Do Daily:

Network Architecture & Engineering: Design implement and evolve Sonar's network infrastructure across all office locations and cloud environments. Evaluate and deploy technologies that improve reliability throughput and user experience while reducing operational complexity.

Fortigate Firewall Architecture & Network Segmentation: Configure administer and evolve our Fortigate firewall architecture including rule sets network segmentation policies VPN tunnels and high-availability configurations. Ensure firewall policies prioritize functionality and performance while maintaining a strong security posture in coordination with the Information Security team.

DNS DHCP & Core Network Services: Own the design automation and reliability of foundational network services (DNS DHCP NTP IPAM). Implement policy-as-code and automation to ensure changes are reviewed tested and auditable before reaching production.

Network Monitoring Alerting & Observability: Design implement and maintain network monitoring dashboards alerting rules and diagnostic runbooks. Continuously tune alerts to reduce noise improve signal fidelity and align with SLOs for critical network services and interconnects.

Infrastructure as Code & Network Automation: Use IaC and configuration management (e.g. Terraform Ansible or vendor-native automation) plus scripting languages (e.g. Python Go) to deploy and manage network devices configurations and policies. Treat network configurations as software artifacts that can be versioned tested and rolled back safely.

Multi-Cloud Networking & Hybrid Connectivity: Design and operate cloud networking across GCP Azure and AWS (VPCs VNets peering transit gateways private endpoints cloud-native load balancing) and hybrid connectivity (site-to-site VPN dedicated interconnects) to ensure secure low-latency communication between on-premises and cloud workloads.

Incident Response & Post-Incident Engineering: Participate in the on-call rotation for network services. Lead or contribute to post-incident reviews turning root causes into preventative engineering changes (new alerts automations capacity adjustments or documentation) that reduce MTTR and recurrence.

AI-Enabled Network Operations: Use AI tooling (e.g. LLM-based assistants AIOps platforms) to accelerate alert triage anomaly detection and root cause analysis while keeping humans in control of decisions. Identify opportunities to embed AI in network operations workflows (e.g. capacity forecasting configuration drift detection) and help implement these safely and effectively.

The Experience You Will Need:

Network Engineering & Operations Background: Significant hands-on experience (4-7 years) in network engineering network operations or closely related roles in modern fast-paced environments (e.g. SaaS enterprise IT multi-site corporate networks or cloud-native infrastructure).

Routing Switching & WAN Expertise: Deep practical experience designing and operating enterprise LAN/WAN environments including routing protocols (BGP OSPF) switching (VLANs STP MLAG/VPC) and SD-WAN technologies. Experience with multi-site network architectures and global traffic management.

Fortigate Firewall & Network Security: Proven experience configuring and administering Fortigate/FortiOS firewall platforms including policy management VPN (IPSec and SSL) SD-WAN and high-availability configurations. Experience implementing network segmentation and zero-trust network access principles. Familiarity with other firewall platforms (e.g. Palo Alto cloud-native firewalls) is a plus.

Multi-Cloud Networking: Hands-on experience with cloud networking across GCP Azure and AWS including VPC/VNet design peering transit gateways cloud-native load balancing and hybrid connectivity (VPN Direct Connect/Cloud Interconnect/ExpressRoute). Experience managing network infrastructure across multiple cloud providers simultaneously is strongly preferred.

Automation & Infrastructure as Code: Strong experience with network automation tools and frameworks (e.g. Ansible Terraform Nornir NAPALM or vendor-native APIs) and with scripting/programming languages (e.g. Python Go or equivalent) to automate network provisioning and configuration management. Track record of converting manual repetitive operational work into reliable automation and self-service capabilities.

DNS DHCP & IPAM: Practical experience operating and automating foundational network services at enterprise scale with a focus on reliability auditability and integration with broader infrastructure automation.

Network Monitoring & Observability: Proven experience with network monitoring and observability platforms (e.g. SNMP-based tools Datadog ThousandEyes LibreNMS or similar) including building dashboards tuning alerting and working with SLIs/SLOs and error budgets for critical network services.

Incident Management & Cross-Functional Collaboration: Demonstrated experience participating in or leading incident response root cause analysis and post-incident follow-through in partnership with IT Ops Security and Engineering. Strong communication skills in English able to explain complex network and operational topics to both technical and non-technical audiences.

AI Fluency: Comfortable using modern AI tooling (e.g. LLM-based assistants automation frameworks) as part of daily work for analysis content generation and workflow automation. Ability to reason about where AI is and isn't appropriate in network operations balancing speed with risk and control.

What We Do

Sonar provides the essential verification layer for the AI-driven development era ensuring all code—whether human-written or AI-generated—is code you can trust.Today AI coding tools are generating explosive volumes of code. This has created an "engineering productivity paradox" : faster code writing doesn't automatically lead to faster safer software delivery. The new bottleneck is verification.Sonar solves this. Integrating code quality and code security into a single platform (SonarQube) Sonar is the foundation for high performance software engineering analyzing over 750 billion lines of code daily to ensure applications are secure reliable and maintainable. As an independent verification platform Sonar enables organizations to securely develop at the speed of AI. We are driven by a deep belief in our people a commitment to excellence and an unwavering dedication to delivery. We operate as a united group where our collective success is the sum of each individual's contributions. Our company culture is driven by the values of CODE: Committed Obsessed Deliberate & Effective. This mindset reflects our culture of creativity collaboration and pride in the work we do.
