Senior Principal Software Engineer, Docker and Ecosystem
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.
_______________________________________________________________________
Docker is seeking a Senior Principal Engineer to serve as the technical visionary and architect for how software gets built, verified, and trusted.
Every day, millions of developers pull images, install dependencies, and ship builds to production. Each of those steps is a place where something can go wrong, or be made to go wrong. Compromised base images, malicious packages, tampered build steps, unsigned artifacts moving through pipelines nobody is watching. The industry calls this the software supply chain, and it has become one of the most consequential unsolved problems in software engineering.
Docker sits at the exact center of it. We are the layer where builds happen. That gives us a rare opportunity, and a real obligation, to make secure software delivery the default rather than an afterthought bolted on at the end.
This role sits in Docker and Ecosystems, the group that owns Docker’s most well known products and our emerging content and SDLC business. You will own the technical strategy for secure software delivery across all of it, defining what verifiable, tamper-resistant software delivery looks like at Docker's scale, then driving the architecture that makes it real for every developer and every enterprise customer using our products.
This is one of the highest-leverage individual contributor roles at the company. You will set multi-year technical direction, make architectural decisions that shape Docker's product portfolio, and work directly with the SVP of Engineering and executive team on strategy. You will not manage people. You will change what the industry considers table stakes.
Responsibilities ====================
Technical Vision and Strategy
- Own the multi-year technical vision for Docker's build security and software supply chain capabilities, spanning Docker Desktop, Docker Hub, Docker Hardened Images, Docker Verified Publishing, and the platforms that monetize them
- Define what "trusted by default" means architecturally for a product used by 20 million developers, then sequence the work to get there
- Translate Docker's commercial strategy into platform capabilities, partnering with the SVP of Engineering to turn organizational strategy into technical roadmaps that span teams and years
- Establish the architectural principles and security standards that guide technical decisions across engineering, and set the bar other teams build against
- Identify the investments with maximum leverage: capabilities built once that raise the security floor across every Docker product
- Anticipate where supply chain threats and regulatory requirements are heading, and make sure our architecture is positioned before the market demands it
Build Security Architecture
- Architect the systems that detect and prevent threats introduced during the software build process, including compromised dependencies, malicious build steps, tampered artifacts, and untrusted base images
- Design provenance and attestation infrastructure so that any artifact produced through Docker carries verifiable evidence of how, where, and from what it was built
- Define Docker's approach to artifact signing, verification, and policy enforcement across the developer inner loop and CI/CD pipelines
- Architect SBOM generation, dependency analysis, and vulnerability intelligence capabilities that give developers and security teams a truthful picture of what is actually in their software
- Align Docker's architecture with emerging supply chain security frameworks and standards, and help shape them where we can
- Design for a hard constraint: security controls that slow developers down get turned off. Everything here has to be fast enough and quiet enough that developers keep it on
SDLC and Developer Workflow Integration
- Architect how Docker's security capabilities integrate across the full software development lifecycle, from local development through CI/CD to production deployment
- Design the interfaces and contracts that let Docker's tooling embed into the pipelines, registries, and platforms customers already run, rather than asking them to rebuild around us
- Define the developer experience for security tooling, where the secure path is the fast path and the default path
- Architect policy and enforcement models that satisfy enterprise security and compliance requirements without fragmenting the developer workflow
- Drive convergence of security capabilities across Docker products, replacing product-specific implementations with shared platform primitives
Technical Excellence and Influence
- Work with leaders across engineering to drive strategy and execution
- Mentor and develop Staff and Principal engineers, raising the technical bar across the organization
- Represent Docker's security architecture externally through blog posts, conference talks, standards bodies, and technical community engagement
- Participate in executive-level discussions, providing architectural perspective on business decisions
- Take part in on-call rotation for your team, respond to incidents, debug production issues, and drive continuous improvement of system reliability
Qualifications ==================
Required ------------
Domain Expertise
- 12+ years of software engineering experience, with deep expertise in build security, software supply chain security, SDLC tooling or equivalent experience
- Demonstrated understanding of the threat model around the software build process: how compromise gets introduced through dependencies, build environments, artifacts, and pipelines, and what actually mitigates it
- Hands-on architectural experience with some meaningful subset of: artifact signing and verification, provenance and attestation, SBOM generation and consumption, dependency and package security, CI/CD pipeline security, base image trust, or vulnerability intelligence at scale
- Working knowledge of supply chain security frameworks and standards, and their practical architectural implications
- Expert-level understanding of API design, service architecture, and system integration patterns at scale
- Proven track record architecting and delivering large-scale distributed systems serving millions of users and thousands of enterprise customers
- Experience with cloud platforms (AWS, GCP, or Azure) and modern infrastructure patterns
- Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent practical experience
Strategic & Business Impact
- Track record of establishing strategic technical plans that directly enabled business outcomes such as revenue growth, market expansion, or unblocked enterprise deals
- Experience translating business strategy into technical architecture and roadmaps
- Understanding of SaaS business models, enterprise sales cycles, and how security capabilities influence commercial outcomes
- Experience making build-versus-buy decisions for critical platform components
Leadership & Influence
- Proven ability to drive large cross-company technical programs requiring coordination across multiple engineering organizations
- Experience working with VPs and executives to set and execute technical strategy
- Track record of influencing technical direction without direct authority, building consensus across teams with competing priorities
- Strong communication skills, with the ability to present to executives and drive alignment at every level
- Experience mentoring senior engineers and developing technical leadership
Enterprise Platform Experience
- Experience building products that serve enterprise customers with complex security and compliance requirements
- Knowledge of enterprise security requirements and compliance frameworks such as SOC 2 and ISO 27001, and their architectural implications
- Understanding of how enterprise security teams evaluate, procure, and operate tooling
Preferred -------------
- Background at a security company, developer tools company, or infrastructure software company operating at significant scale
- Experience with container technologies, Docker, Kubernetes, or developer productivity platforms
- Experience with enterprise billing complexity, including contract management, usage-based pricing, and revenue recognition
- Track record of migrating legacy systems while maintaining business continuity
- Contributions to open source security tooling or participation in supply chain security standards work
- External recognition as a technical leader through conference speaking, publications, or open source contributions
- Advanced degree in Computer Science, Engineering, or a related technical field
Key Success Metrics =======================

- Build-time threat classes are addressed architecturally rather than through detection after the fact
- Developers keep security controls enabled because the controls are fast and unobtrusive
Business Enablement
- Security and governance capabilities directly unblock enterprise revenue
- New product SKUs launch in weeks instead of months through the billing platform
- Usage-based billing supports monetization of new security and AI product lines
Platform Leverage
- Product teams ship enterprise-ready, secure-by-default features in under two weeks rather than months
- Shared security primitives replace fragmented per-product implementations
- Platform systems achieve 99.9%+ uptime for business-critical workflows
Organizational Impact
- Recognized across Docker as the definitive technical authority on build and supply chain security
- Multiple Staff and Principal engineers developed who can own major domains
- Docker's voice carries weight in the external supply chain security conversation
