Job summary

Docker, Inc is seeking a technically minded engineer to own the sandboxing stack, building secure, isolated runtime environments for AI agent workloads. You’ll lead design, implementation, and scaling of sandbox infrastructure used by developers across macOS, Windows, and Linux.

With a remote-first culture and offices in Seattle and Paris, the role emphasizes autonomy, architectural leadership, and close collaboration with product and open source communities.

• Familiarity with the agentic software development ecosystem: how coding agents work and how tools like Claude Code, Codex, or similar agents interact with their environment.
• Ability to reason about isolation and security boundaries: what a sandbox should and shouldn’t expose, and how to make safe defaults obvious to users.
• Experience driving architecture and technical strategy across multiple engineers or teams.
• Strong written and verbal communication skills.
• Comfortable working with a high degree of autonomy in a remote-first environment.

Responsibilities

• Design, develop, and lead improvements to the sandboxes product across agent integration, tool permissions, and developer-facing workflows.

• Drive the reliability and performance of sandbox creation, session management, and teardown for AI agent workloads.
• Collaborate with peers, Product, and adjacent teams to evolve the architecture as requirements grow.
• Mentor engineers on the team and set the bar in design reviews and code reviews.
