Across our multiple offices globally, we are united by our core principles: We Before Me , Do the Right Thing , and Get Things Done . These shared values drive our culture, shape our processes, and foster a friendly, rewarding, and diverse environment for every OK-er. We are looking for a Security Operations Engineer who combines hands-on engineering skills with security operations expertise. You will be deeply involved in the operations and troubleshooting of both server-side and client-side components within our Zero Trust architecture, drive security risk governance initiatives, and leverage AI tools to continuously improve system stability and compliance.
Responsibilities
- K8s Operations & Vendor Engagement: Develop deep expertise in K3s / Kubernetes, including version management and disaster recovery. Independently identify and reproduce system issues, proactively engage with vendors to drive root cause analysis and resolution - not just workarounds.
- Zero Trust Network Access Governance: Work closely on Zero Trust initiatives, participate in cluster network configuration and troubleshooting, identify device compliance risks, drive remediation of non-compliant devices, and continuously optimize access control policies.
- Monitoring & Observability: Build and continuously improve log monitoring systems; proactively surface system risks through alert rules and trend analysis.
Requirements
- Solid understanding of Kubernetes / K3s core concepts; able to independently diagnose cluster-level issues.
- Foundational knowledge of security principles and Zero Trust model; strong networking fundamentals with the ability to independently troubleshoot and analyze network connectivity issues.
- Hands-on experience with AI tools (e.g., Claude, Codex, or equivalents) for day-to-day tasks including log analysis, scripting, fault diagnosis, and documentation.
- Bachelor's degree or above in Computer Science, Information Security, Network Engineering, or a related field; 3-5 years of relevant experience.
- Experience with DACS / NAC or similar device access control system operations or risk governance.
- Familiarity with monitoring and logging platforms such as Prometheus + Grafana, ELK, or Loki.
- Hands-on experience building AI Agents or implementing tool-calling workflows.
- Proven track record of collaborating with external vendors to drive issue resolution.
- AI-Forward: You actively explore and integrate AI tools into your daily workflow to boost efficiency.
- Owner Mindset: You take genuine ownership of system health - you don't just close tickets.
- Strong Communicator & Driver: You can clearly articulate technical issues and effectively push cross-functional teams and vendors toward resolution.
- Self-Starter: You don't wait to be told - you proactively spot problems and drive them to closure.
