Benefits

Qualifications

• 6+ years of experience in security engineering, application security, or a closely related discipline, with a track record at senior or staff level.
• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
• Strong proficiency in Go, with the ability to review and contribute to production-grade code.
• Deep understanding of Linux fundamentals relevant to container security: namespaces, cgroups, capabilities, seccomp profiles, AppArmor/SELinux, rootless containers, and privilege boundaries.
• Solid grasp of OCI specifications and container runtime security (e.g.
• runc, containerd, BuildKit).
• Hands-on experience with identity and access management concepts: OAuth 2.0, OIDC, token handling, and auth flows in desktop or cloud-adjacent contexts.
• Experience performing security design reviews, threat modeling, and participating in secure development workflows.
• Familiarity with vulnerability management processes: CVE triage, CVSS scoring, coordinated disclosure, and working with external reporters.
• Strong written and verbal communication

Responsibilities

• Partner with engineering and product teams throughout the development lifecycle to identify security risks early, from design review through code review and release.
• Conduct threat modeling and security design reviews for new and evolving product features, with particular focus on authentication, authorization, and container runtime security.
• Serve as the team's primary liaison to the organization's security group, attending security syncs, relaying guidance, and translating central policy into practical engineering decisions.
• Act as the first point of contact for incoming vulnerability reports and CVEs: validate severity, reproduce issues, coordinate disclosure timelines, and drive remediation with the relevant engineers.
• Review Go code with a security mindset, identifying classes of issues such as privilege escalation, insecure defaults, injection risks, and improper credential handling.
• Contribute security-focused improvements directly to the codebase where appropriate.
• Develop and maintain internal security documentation, guidelines, and runbooks for the team.
• Stay current on the Linux security landscape as it pertains to containers: namespaces, cgroups, seccomp, AppArmor, capabilities, and the evolving OCI ecosystem.
• This role may require participation in an on-call rotation to provide support outside of standard business hours, including evenings, weekends, and holidays, as needed.
