Senior Developer, Open Source
WFA Digital Insight
The Open Source Senior Developer seat at 1Password sits at the intersection of security tooling and developer experience, a rare blend that few companies offer. While most open‑source roles focus on maintaining libraries, this position pushes the envelope by embedding 1Password’s security primitives directly into IDEs through agent hooks and plugins. Candidates will be the technical voice for the open‑source community, steering architecture, handling public contributions, and ensuring the codebase stays both extensible and secure. Because the team is already experimenting with AI‑assisted development, a comfort level with emerging agentic IDEs will set applicants apart. The role reports into the broader Open Source team and works closely with product, design, and security stakeholders, making visibility and cross‑functional communication essential.
Job Description
1Password is growing. We’ve surpassed $400M in ARR and we’re continuing to accelerate, earning a spot on the Forbes Cloud 100 for four years in a row and teaming up with iconic partners like Oracle Red Bull Racing. About 1Password At 1Password, we’re building the foundation for a safe, productive digital future. Our mission is to unleash employee productivity without compromising security by ensuring every identity is authentic, every application sign-in is secure, and every device is trusted. We innovated the market-leading enterprise password manager and pioneered Unified Access Management, a new cybersecurity category built for the way people and AI agents work today. As one of the most loved brands in cybersecurity, we take a human-centric approach in everything from product strategy to user experience. Over 180,000 businesses, from Fortune 100 leaders to the world’s most innovative AI companies, trust 1Password to help their teams securely adopt the SaaS and AI tools they need to do their best work. If you're excited about the opportunity to contribute to the digital safety of millions, to work alongside a team of curious, driven individuals, and to solve hard problems in a fast-paced, dynamic environment, then we want to hear from you. Come join us and help shape a safer, simpler digital future. We are seeking an Intermediate Developer on our Open Source Team, focused on strengthening 1Password's open source posture and making our developer tools easy to use directly inside developers' workflows through agentic IDE integrations: our Agent Hooks and IDE plugins. You'll participate in the complete lifecycle of a feature, contributing to planning, doing the development work, and seeing it through release and customer support, while consistently delivering projects within the team. How we’re using AI today Our Engineering, Product, and Design teams are thoughtfully integrating AI across the full software and product development lifecycle to move faster without sacrificing quality or security. In practice, that looks like engineers using AI-assisted coding tools to accelerate reviews and catch bugs earlier, product managers synthesizing user research at scale, and designers rapidly prototyping and iterating with AI-generated mockups. We approach AI the same way we approach security: with clear principles, human accountability at every consequential decision point, and rigorous evaluation before anything ships to customers. This is a remote opportunity within Canada and the US.
What We're Looking For
- Professional software development experience, with the ability to take a reasonably scoped feature from plan to release with a high degree of independence.
- Working knowledge of the technologies and tools needed to complete tasks independently.
- Solid experience with a modern development toolchain (Git, IDEs, terminal, debugging and testing, dependency management) and the languages relevant to the team's work.
- Good written communication and documentation habits, suited to working in public repositories.
- Interest in developer tooling, IDE and agent integrations, and/or open source community work.
- Interest in agent-assisted development and building tools to make agent-assisted development smoother and more secure.
- A security-conscious mindset aligned with 1Password's principles.
- Familiarity with AI-enabled or agentic IDEs (e.g., Cursor) or building editor/IDE extensions. What you can expect: - Acquire and maintain a solid understanding of your development toolchain and use it to contribute new features, improvements, and bug fixes across the team's codebases.
- Participate in the complete lifecycle of a feature: contribute to planning, do the development, and help oversee its release and customer support.
- Ensure code is high quality and maintainable by developing new testing strategies in addition to existing ones, writing unit and integration tests for new and existing code, documenting your work thoroughly, and reporting issues effectively.
- Plan your solutions ahead of writing code, recognize and reuse existing patterns and best practices (development, security, quality), and submit well-documented merge requests.
- Participate in and review documented proposals (RFCs/RFDs), promote best practices in code reviews, and provide thoughtful peer feedback.
- Empower our customer support team to better support our products, address tough issues driving support inflows, and help determine high-priority customer feedback.
- Be an active participant in team organization: refinement, prioritization, and group estimation.
- Be curious and on the lookout for improvement opportunities you can suggest or tackle yourself, whether in repo cleanup, community engagement tooling, or IDE integration ergonomics.
How to Stand Out
- Showcase any public open‑source contributions in your resume; links to active repositories demonstrate the community engagement we value.
- Prepare a short walkthrough of a plugin or IDE extension you built, highlighting design decisions and security considerations.
- Familiarize yourself with 1Password’s developer documentation and the current open‑source repos before the interview.
- Emphasize experience with agent‑hook or AI‑assisted development tools; practical examples will set you apart.
- During negotiations, reference the equity component and remote‑work stipend as part of the total compensation package.
- Watch for interview questions that probe how you handle security trade‑offs in public codebases; be ready with concrete scenarios.
