You will partner closely with engineering, platform, infrastructure, and executive stakeholders to influence security direction, guide the design of secure systems, and establish scalable security practices across the organization. The ideal candidate brings extensive experience securing Kubernetes-based environments, distributed systems, and modern cloud-native platforms while demonstrating the ability to lead complex initiatives and drive security outcomes at organizational scale.  Responsibilities  * Define and drive the long-term security architecture and strategy across cloud, infrastructure, application, platform, and operational security domains.  * Own the bug bounty program for Alkira on HackerOne: triage, severity assessment, coordination of remediation with owning teams, and researcher communication.  * Serve as a technical authority for Kubernetes, container, Linux, and cloud security, influencing security decisions across engineering organizations.  * Lead security architecture reviews and establish standards for secure design, implementation, and deployment of cloud-native systems.  * Drive enterprise-wide risk reduction initiatives through threat modeling, vulnerability management, and proactive security assessments.  * Build detection engineering and security monitoring on our observability stack (Coralogix), and lead security investigations, incident response, and post-incident improvements across complex distributed environments.  * Design and implement scalable security controls, automation, and engineering frameworks that improve security posture and operational efficiency.  * Lead security investigations, incident response efforts, and post-incident improvements across complex distributed environments.  * Partner with senior engineering and business leaders to align security initiatives with company objectives and platform growth strategies.  * Mentor security and engineering teams while establishing security best practices, governance models, and technical standards.  * Participate in the on-call rotation that handles security alerts and incoming threats  Minimum Qualifications  * Bachelor’s degree in Computer Science, Cybersecurity, Engineering, or a related technical field, or equivalent practical experience.  * 10+ years of experience in cybersecurity, security engineering, infrastructure security, or cloud security roles.  * Deep expertise securing large-scale cloud-native environments, distributed systems, and modern application platforms.  * Advanced expertise with Kubernetes security, including workload protection, container security, platform hardening, and runtime security.  * Expert-level Linux administration, hardening, automation, troubleshooting, and system-level security experience.  * Ability to write production-quality automation and tooling in Go, Python, or a comparable language.
