Job Summary
Who is Sonar
Sonar is driving the future of agent-centric software development. As the leader in AI code review and verification we solve a critical problem: ensuring that software generated by AI-assisted developers or autonomous agents is reliable secure and maintainable.
Integrating seamlessly with Claude Code Codex Cursor GitHub Copilot Gemini and Devin we help over 75% of the Fortune 100 build trusted reliable compliant software. Customers who use Sonar are 44% less likely to report an outage due to AI-generated code.
We believe code verification is the critical missing link in the Agent-Centric Development Cycle (AC/DC). Industry giants like Nvidia ServiceNow Goldman Sachs AstraZeneca and Ford Motor Company count on us to provide independent explainable consistent review and governance of their AI-generated code via products like:
SonarQube: The worlds leading AI code review and verification platform.
SonarQube Foundation Agent: Currently topping the leaderboards for agentic software repair.
SonarSweep & Sonar Context Augmentation: Providing the enterprise-grade context and constraints agents need to be truly effective.
Our team operates across global hubs in Austin Bochum Dubai Geneva London Singapore Tokyo and Washington D.C. We move with a mindset we call CODE:
Committed to our customers and community.
Obsessed with quality.
Deliberate in our decisions.
Effective as one team.
With over $400M in revenue and profitable fast-paced growth we are building the backbone of the AI software revolution. If youre hungry to have an impact want to build at a fast pace and ready to work at the forefront of AI we want to hear from you.
Position description
We are still at the beginning of our growth journey and are continuously introducing new processes technologies and this role you will:
Be a pivotal engineering contributor to the design implementation and operation of Sonars global network infrastructure spanning all office locations and cloud environments ensuring fast secure and reliable connectivity for every SonarSourcer and every service.
Own key parts of our WAN LAN SD-WAN and DNS architecture ensuring that network services are resilient performant and aligned with the needs of a rapidly growing globally distributed organization.
Design and maintain network monitoring alerting and observability capabilities that give us real-time visibility into network health performance and security posture across all sites and cloud interconnects.
Partner with Product Engineering Information Security and Infrastructure Engineering to ensure secure network controls and segmentation are deeply and seamlessly integrated into engineering workflows not bolted on.
Use and champion AI tooling to make network operations more efficient -- from alert triage and anomaly detection to capacity planning and configuration management.
Help define and improve how we measure the reliability and performance of our network services (SLIs/SLOs error budgets and dashboards) making network health visible and actionable to stakeholders.
What you will do
Network Architecture & Engineering: Design implement and evolve Sonars 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.
Experience and qualifications
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 isnt appropriate in network operations balancing speed with risk and control.
