Principal Support Engineer

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 supports customers using the largest and most popular container registry service in the world today, Docker Hub. Millions of users - community developers, open source projects and Independent Software Vendors - push and pull Docker container images billions of times through Docker Hub.

We are seeking a Senior Software Engineer, Agentic Platform to join Support Engineering and accelerate delivery of our agentic platform. You are a strong software engineer first - fluent in modern AI-assisted development (Cursor, Codex, Claude) as a force multiplier, but disciplined about shipping: tests, review, evals, and production hygiene are non-negotiable.

Working in strong partnership with the Principal Engineer and Support Engineering leadership, this is reliable vibe coding at scale - fast iteration with AI tools, never at the expense of dependable systems. You provide broad coverage across UI, APIs, integrations, data surfaces, and agentic workflows, with observability, 12-factor discipline, and safe human handoff.

• Integrate CRM, warehouse, ticketing, incident management, and knowledge systems with clear contracts, retries, idempotency, and auditability Improve reliability, performance, and trust through metrics, logs, traces, dashboards, and production operating practices

• Build safe tool access patterns with least-privilege permissions, audit trails, and human approval for sensitive actions

• Participate in on-call rotation for systems your team owns

Minimum Qualifications:

• Daily fluency with AI-assisted development (Cursor, Codex, Claude, or similar) paired with the judgment to keep output reviewable, testable, and production-safe 6+ years of experience building production web applications, backend services, internal platforms, or distributed systems
