The role

Summary

As a Senior Developer on 1Password's Open Source Team, you'll lead the development of agent-integrated IDE plugins and Agent Hooks that enable developers to securely authenticate and access 1Password directly within their development workflows. This role requires ownership of medium-to-large architectural initiatives, community engagement across public repositories, and close collaboration with product and partnership teams to strengthen 1Password's position in the emerging agent-assisted development ecosystem. You'll combine deep technical expertise in modern development toolchains with security-first thinking to build extensible, maintainable systems that serve 180,000+ businesses trusting 1Password for unified access management.

What you'll do

Architectural Leadership and Technical Direction: Own architectural decisions for Agent Hooks, IDE plugins, and integrations; establish technical patterns that ensure systems remain scalable, secure, and aligned with 1Password's authentication and security models. Drive decisions on extensibility frameworks, plugin architecture, and integration points across emerging agentic IDE ecosystems.

End-to-End Feature Delivery: Lead the complete development lifecycle of medium-to-large projects from initial planning, design, and implementation through testing, deployment, and customer support. Deliver high-impact features such as extending Agent Hooks across multiple IDEs and building genuine in-IDE value beyond documentation links.

Code Quality and Testing Standards: Raise the quality bar across the Open Source Team by identifying and addressing code quality gaps, testing coverage deficiencies, and documentation lapses in community-facing repositories. Anticipate potential problems, report technical risks, and foster a culture of rigorous testing and comprehensive documentation.

Community Engagement and Open Source Stewardship: Work effectively in public by engaging with external contributors, code reviewers, and the broader open source community. Uphold high quality standards in community-facing repositories, manage public-facing technical communication, and build trust with developers using 1Password's open source tools.

Roadmap Planning and Technical Opportunity Identification: Contribute to the team's 6-month roadmap by identifying emerging technical opportunities, architectural risks, and platform improvements. Translate product and partnership requirements into actionable technical work aligned with team objectives and 1Password's strategic direction.

Cross-Functional Collaboration: Ensure seamless alignment with Partnerships, Product, UX, and SDK/CLI teams. Translate cross-functional requirements into clear technical specifications, provide technical insights during product planning, and maintain regular communication with stakeholders on project progress and technical decisions.

Developer Experience Optimization: Drive initiatives that enhance the developer experience for customers using 1Password on your platforms. Identify and mitigate issues developers face when integrating 1Password with their tools, build smoother workflows for agent-assisted development, and advocate for developer-friendly design patterns.

Team Culture and Knowledge Sharing: Contribute to a positive, collaborative team environment by modeling best practices, providing constructive code review feedback, documenting architectural decisions, and supporting a culture of shared ownership and continuous learning among team members.
