ABOUT DOCKER

Docker has been one of the most loved brands in developer tooling, trusted by more than 20 million monthly users and over 20 billion container image pulls. From solo founders to the world's largest companies, developers rely on Docker to build, share, and run their applications across our suite of products including Docker Desktop, Docker Hub, and Docker Scout.

We are a globally distributed, remote-first team building the tools that define how software gets built and delivered. As AI agents redefine software development, Docker is at the center of that shift, providing the sandboxed environments, verified images, and secure infrastructure that make autonomous workflows trustworthy by default.

THE ROLE

You are a software engineer who cares deeply about security. Embedded in the Desktop engineering team, you will bring an engineering-first perspective to the security of a complex, cross-platform product built at the intersection of identity, OCI runtimes, and Linux kernel internals. You will read and write Go, participate in feature development, and make security a first-class concern from the inside out: not as an outside reviewer, but as a contributing member of the team.

This role is for someone who is primarily a builder, and who applies that builder’s instinct to making Docker Desktop more secure by default.

What you would do

- Contribute to the Docker Desktop codebase in Go, with a focus on security-sensitive areas such as authentication flows, privilege boundaries, and container runtime behavior.

- Participate in design and code reviews across the team, bringing a security perspective to features before they ship.

- 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 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.

What they are looking for

- 6+ years of software engineering experience, with meaningful exposure to security-sensitive systems or a strong personal interest in security.

- Strong proficiency in Go, with a track record of writing and shipping production-grade code.

- Solid understanding of Linux fundamentals relevant to container security: namespaces, cgroups, capabilities, seccomp profiles, AppArmor/SELinux, rootless containers, and privilege boundaries.

- Familiarity with OCI specifications and container runtime internals.

- Working knowledge of identity and access management concepts: OAuth 2.0, OIDC, token handling, and auth flows in desktop or cloud-adjacent contexts.

- Comfort participating in security design reviews and threat modeling, even if security has not been your primary title.

- 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.

WHAT TO EXPECT

FIRST 30 DAYS

- You will onboard into the team and get hands-on with the Docker Desktop codebase, architecture, and development workflow. You will meet your counterparts in the central security organization and learn how vulnerability reports are currently handled. The goal is to listen, ask questions, and build a clear picture of the product’s current security posture, not to change anything yet.

FIRST 90 DAYS

- You will be an active contributor, writing and reviewing Go code and bringing a security lens to features in flight. You will have taken ownership of the vulnerability intake process, handling your first end-to-end triage cycles with minimal guidance. You will have a working relationship with the engineers on the team and a growing sense of where the most meaningful security investments should be made.

ONE YEAR OUTLOOK (FIRST YEAR)

- You will be a trusted contributor to both the product and its security posture. You will have shipped meaningful improvements directly to the codebase, whether to auth flows, container isolation defaults, or other security-sensitive areas, and driven better security practices across the team’s development lifecycle. Your work will be directly visible in the security and resilience of a product used by millions of developers every day.
