About DockerDocker 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._______________________________________________________________________As a Senior Security Engineer, Offensive Security, you'll help drive offensive security at Docker, putting our products, platforms, and cloud infrastructure under realistic adversarial testing to surface and drive out attack paths before real adversaries find them. You'll partner with engineering, product, and leadership to turn findings into durable fixes and to shape how security is designed into every Docker product.You'll apply your expertise in penetration testing, threat modeling, and exploit development to find and eliminate risks across Docker products and infrastructure. Working across cloud infrastructure (AWS, GCP, Azure), containerized environments, and AI/ML products, you'll implement proactive security solutions that scale with Docker's growth.This role offers the opportunity to help improve security programs at a company whose products are trusted by millions of developers worldwide. You'll work in a fast-paced, technically challenging environment where your security expertise directly impacts both Docker's platform and the broader container ecosystem.Responsibilities:Contribute to security initiatives that align with business goals, helping ensure security is a core component of our products and infrastructureSupport and help implement key security programs such as automated security design reviews, and vulnerability managementBuild deep knowledge of software security and architecture, and act as a go-to resource for engineering teamsPartner with engineering to design and implement security architecture and controls across Docker products and platformsPlan, scope, and execute penetration tests and red-team / adversary-emulation engagements against Docker's products and servicesDevelop proof-of-concept exploits and produce clear, risk-rated findings with actionable remediation guidance, then retest fixes to confirm closureBuild and maintain offensive security tooling and automation to expand testing coverage and repeatabilityPerform security reviews and threat modeling (design, architecture, and code) across Docker products and services, including emerging AI products, and write automated security tests and exploitsServe on rotating on-call schedule to respond to security events, investigate threats, and coordinate remediation effortsEducate and collaborate with cross-functional teams (e.g., engineering, product) to promote security practicesParticipate in Security Incident responseQualificationsHave 3+ years in security engineering, including hands-on offensive security and penetration testing across applications and infrastructure Possess 2+ years of hands-on development experience in Python or Golang Demonstrate deep expertise in authentication, authorization, including technologies like OAuth, cryptography applications and Zero Trust principles.Have strong hands-on experience with securing cloud ecosystems (e.g. AWS, GCP, Azure)Have hands-on penetration testing experience across SaaS web applications and APIs., including manual exploitation beyond automated scannersAre proficient with offensive tooling and techniques such as. Burp Suite, and OWASP frameworksCan write security tests and develop exploits and proof-of-concepts that find real vulnerabilities in a productUnderstand AI/ML security risks and mitigations, including prompt injection, data poisoning, model extraction, and adversarial attacksHave practical experience using LLMs and agentic tooling to automate vulnerability discovery, reconnaissance, and pentesting workflowsHave a track record of building security programs and automations from scratch, applying risk-based prioritizationHave experience performing security reviews and building or improving security review automationHave excellent communication skills, allowing you to explain complex security concepts clearly to technical and non-technical stakeholdersUnderstand industry standards, and actively keep up with emerging security technologies and modelsAre a team player who drives security change via collaboration and cross-functional partnershipsHold offensive security certifications such as OSCP, OSWE, OSEP, GXPN, GPEN, or CRTOHave published CVEs, original security research, or conference talksBonus if you:Have experience with container escape, Kubernetes attack paths, or cloud red teamingHave experience testing AI/ML systems for issues like prompt injection, model extraction, and data poisoningWhat to ExpectFirst 30 days:Meet with security team and key partners across engineeringGain access to team owned systems, and internal documentationComplete security awareness training and compliance onboardingReview application architecture, tech stack and data flowReview risk registry and annual roadmapFamiliarize oneself with team workflows and processesShadow a fellow security engineer during their on-call/secops rotationsFirst 90 days:Conduct security review on emerging Docker productsScope and execute your first penetration test against a Docker product or serviceActively participate in architecture design reviews with the teamContribute to a Security-owned project or initiative Collaborate with Docker developers to validate and resolve discovered vulnerabilitiesEnhance incident response capabilities by participating in on-call rotation and post-incident activitiesCreate and maintain security documentation and runbooks First Year OutlookContribute to the security roadmap for improving security controlsStrengthen Zero Trust architecture and least privilege access controlsEnhance security monitoring and anomaly detectionPerform security reviews for major product releasesOwn and run recurring penetration tests and adversary-emulation exercises across Docker products, and engage with external researchersSupport audits and ensure compliance with SOC 2, ISO 27xxxAdvocate for “security by design” in all product featuresBecome well versed in Docker products and emerging AI technologiesDocker does not offer visa sponsorship for this role.
