Technical leader owning architectural decisions and driving medium-to-large projects from planning to customer support.

Responsibilities

  • Contribute large new features, significant product improvements, and critical bug fixes, such as extending our 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 ~6 months out, then lead execution aligned to team objectives.
  • Raise the quality bar by identifying lapses in code quality and gaps in testing coverage, anticipating and reporting potential problems, 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.
  • Contribute to a positive, collaborative team environment by modeling best practices, providing constructive feedback, and supporting a sense of shared ownership.

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; comfortable reading, writing, and reviewing others' code.
  • Experience designing extensible, maintainable systems, ideally developer tooling, IDE extensions, agent integrations, or actively maintained open source projects.
  • Demonstrated ability to set technical direction and make architectural decisions that keep products scalable, secure, and high quality.
  • 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 agent-assisted development smoother and more secure.
  • Excellent written and verbal communication skills, with the ability to make a project's impact and progress visible to engineering, product, and design stakeholders.
