You will work closely with engineering teams to design, assess, and improve the security of large-scale distributed systems operating in production environments. This is a hands-on engineering role focused on Kubernetes security, cloud-native infrastructure, CI/CD systems, software supply chains, identity and access management, and production deployment platforms. Your work will directly impact the reliability, resilience, and security of critical infrastructure supporting real-world autonomous system operations.\nWhat You’ll Get To Do\nDesign and improve the security architecture of cloud-native infrastructure and Kubernetes environments\nSecure CI/CD systems, software supply chains, build pipelines, and deployment workflows\nImprove identity, authentication, secrets management, and access control across production systems\nHarden Kubernetes clusters, containerized workloads, and runtime environments against modern attack vectors\nConduct threat modeling and security reviews across infrastructure and operational systems\nPartner closely with engineering teams to integrate practical security controls into development and operational workflows\nInvestigate vulnerabilities affecting production infrastructure and help drive remediation and resilience improvements\nHelp define security standards and best practices for large-scale distributed systems and operational infrastructure\nWhat You Have\nBachelor’s degree in Computer Science, Computer Engineering, Cybersecurity, or a related technical field\n5+ years of experience in infrastructure security, cloud security, platform security, SRE, or related domains\nStrong software engineering, systems engineering, and networking fundamentals\nExperience securing cloud infrastructure and distributed production systems\nExperience with Kubernetes, containerized environments, CI/CD systems, and infrastructure automation\nFamiliarity with identity and access management, secrets management, authentication systems, and secure infrastructure design\nExperience with threat modeling, security architecture reviews, vulnerability management, or adversarial security assessments\nStrong collaboration and communication skills with the ability to work cross-functionally across infrastructure and engineering teams\nPractical engineering judgment and the ability to balance security, operational reliability, scalability, and development velocity\nThe Extras That Set You Apart\nExperience securing large-scale distributed or cloud-native systems\nFamiliarity with software supply chain security, artifact signing, or build provenance systems\nExperience with runtime security, Kubernetes security, or production infrastructure hardening\nBackground in platform engineering, SRE, infrastructure engineering, or cloud-native operations\nExperience with offensive security, penetration testing, or adversarial infrastructure assessments\nExperience supporting operationally critical or mission-critical production environments","description_format":"text","description_chars":3107,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics
