Senior Developer, Open Source

1Password is hiring a Senior Developer for its Open Source team, focused on strengthening the company's open source posture and making its developer tools easy to use directly inside developers' workflows through agentic IDE integrations: Agent Hooks and IDE plugins. You'll serve as a technical leader on the team, owning architectural decisions and driving cohesive execution on medium-to-large projects, from initial planning through development and into customer support.

Responsibilities

• Contribute large new features, significant product improvements, and critical bug fixes, such as extending Agent Hooks across IDEs or building genuine in-IDE value beyond links to external docs.
• Make architectural decisions that keep integrations and public repositories scalable, secure, and aligned to 1Password's existing security and authentication models.
• Contribute to the team's roadmap by identifying technical opportunities and risks up to six months out, then lead execution aligned to team objectives.
• Raise the quality bar by identifying lapses in code quality and gaps in test coverage, and fostering a high standard of documentation across community-facing repositories.
• Ensure alignment with cross-functional partners (Partnerships, Product, UX, and the SDK/CLI teams), translating requirements into actionable work.
• Drive initiatives that better support 1Password customers on your platform and mitigate issues developers face.

Qualifications

• Significant professional software development experience, with a track record of independently owning and delivering medium-to-large technical projects end to end.
• Advanced, hands-on command of a modern development toolchain (Git, IDEs, terminal, debugging and testing tools) and the languages relevant to the team's work.
• Experience designing extensible, maintainable systems, ideally developer tooling, IDE extensions, agent integrations, or actively maintained open source projects.
• A track record of working effectively in public, engaging with external contributors and upholding a high quality bar in community-facing repositories.
• Interest in agent-assisted development and building tools to make it smoother and more secure.
• A security-minded approach consistent with 1Password's principles.
• Bonus: experience maintaining a popular open source project, familiarity with agentic IDEs (e.g. Cursor) and the emerging agent-hook ecosystem, or OSPO experience.
