Docker, Inc. is a leading company in developer tooling, trusted by millions of users worldwide. They are seeking a Senior Security Engineer to own the security posture of Docker Desktop, partnering with various teams to identify security risks and ensure the integrity of the product through thorough reviews and improvements.
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
Requirements:
- 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 skills; comfortable bridging the gap between a dedicated security team and a product engineering team
