Infrastructure Security Engineer (f/m/d)
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, Booking.com, 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 world's 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 you're 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 tools. In this role, you will:
Be a pivotal engineering contributor to the design, implementation, and operation of security controls and automation across our identity platforms, endpoints, and core IT services.
Own key parts of our IdP and access automation stack (e.g., SSO, SCIM, groupbased access, JIT access), ensuring that users get the right access at the right time with strong controls and auditability.
Design and maintain security monitoring, alerting, and SIEM integrations that give us realtime visibility into identity, endpoint, and SaaS risks.
Partner with IT Ops, Information Security, and Infrastructure Engineering to ensure security controls are deeply integrated into operations (incident management, change, and problem processes), not bolted on.
Use and champion AI tooling to make security operations more efficient - from alert triage and runbook execution to knowledge retrieval and reporting.
Help define and improve how we measure the reliability and effectiveness of our security controls (SLIs/SLOs, error budgets, and dashboards), making risk and performance visible and actionable to stakeholders.
What you will do
Security Monitoring, Alerting & SIEM Ownership: Working with the Information Security team, design, implement, and maintain alerting rules, dashboards, and runbooks across our SIEM and logging platforms, with a focus on identity, access, and SaaS security signals. Continuously tune alerts to reduce noise, improve fidelity, and align with error budgets and SLOs for critical security and identity services.
Endpoint Defense In Depth: Architect and implement our multilayer endpoint defence systems (e.g. Crowdstrike, Cyberark, Cloudflare, secure browser policies), balancing risk against usability in coordination with the Information Security team.
Identity Platform & Access Automation: Build and maintain automation for our identity platforms (e.g., SSO, SCIM provisioning, groupbased access policies, lifecycle workflows) in partnership with Information Security. Implement guardrails and policyascode for identity, ensuring changes are reviewed, tested, and auditable before reaching production.
Infrastructure as Code & Security Controls as Code: Use IaC and configuration management (e.g., Terraform, Ansible, or similar) plus scripting languages (e.g., Python, Go) to deploy and manage security tooling, integrations, and policies. Treat security controls (e.g., logging, scanning, hardening, secret management) as software artifacts that can be versioned, tested, and rolled back safely.
Observability & Integration with Core IT Operations: Ensure that logging, metrics, and tracing for securityrelevant systems (IdP, VPN, endpoint protection, critical SaaS) are robust, accurate, and integrated into our observability stack. Integrate security events and automations with ITSM and incident management workflows, enabling fast routing, triage, and resolution.
Incident Response & PostIncident Engineering: Participate in the oncall rotation for relevant security and identity services. Lead or contribute to postincident reviews, turning root causes into preventative engineering changes (new alerts, automations, guardrails, or documentation) that reduce MTTR and recurrence.
AIEnabled Security Operations: Use AI tooling (e.g., LLMbased assistants, automation platforms) to accelerate alert triage, enrichment, and investigation, while keeping humans in control of decisions. Identify opportunities to embed AI in security and IT operations workflows (e.g., threat intelligence and alert correlation) and help implement these safely and effectively.
Experience and qualifications
Security Engineering & Operations Background: Significant handson experience (4-7 years) in security engineering, security operations, or closely related roles in modern, fastpaced environments (e.g., SaaS, enterprise IT, cloudnative infrastructure).
Identity & Access Management Expertise: Practical experience operating IdPs and IAM systems at scale (e.g., Okta, Azure AD, or similar), including SSO, MFA, lifecycle management, and leastprivilege policies. Experience designing and implementing automated provisioning and deprovisioning (e.g., SCIM, HRIS integrations, groupbased and rolebased access models).
SIEM, Logging & Observability: Proven experience with SIEM and observability platforms (e.g., ELK/EFK, Splunk, Datadog, or similar), including writing and tuning detection rules, building dashboards, and working with largescale log ingestion. Comfort working with SLIs/SLOs and error budgets for critical services, and using these to guide priorities for hardening and automation.
Automation & Infrastructure as Code: Strong experience with IaC and configuration management tools (e.g., Terraform, CloudFormation, Ansible, or similar) and with scripting/programming languages (e.g., Python, Go, or equivalent) to automate security and operational tasks. Track record of converting manual, repetitive operational work into reliable automation and selfservice capabilities.
Security Controls Implementation: Experience implementing and operating security controls as code: vulnerability scanning, configuration baselines, secret management (e.g., HashiCorp Vault), key rotation, and certificate management.
Incident Management & CrossFunctional Collaboration: Demonstrated experience participating in or leading incident response, root cause analysis, and postincident followthrough in partnership with IT Ops, Security, and Engineering. Strong communication skills in English, able to explain complex security and operational topics to both technical and nontechnical audiences.
AI Fluency: Comfortable using modern AI tooling (e.g., LLMbased 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 security and operations, balancing speed with risk and control.
