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.

As a Senior Developer, you'll join the team that owns our device-resident agent and expand how 1Password software is installed, configured, and managed across customer devices. You'll work on a deeply technical client daemon that runs directly on macOS, Windows, and Linux as a background service, with close integration into each operating system.

This role sits within an established agent team, but with meaningful ownership of new capabilities. You'll help design and build the mechanisms that make enterprise deployment simpler, more reliable, secure, and observable at scale, while ensuring they fit naturally into the agent architecture and the broader 1Password platform.

While your primary focus will be the endpoint agent and its communication model, you'll also help shape the contracts and supporting services around it. In practice, that may include prototyping or building lightweight backend components needed to validate workflows, lifecycle behaviors, and end-to-end system design.

You'll help shape our enterprise installation and lifecycle experience end-to-end, ensuring reliability, security, and observability at scale.

This is a remote opportunity within Canada and the US.

What we're looking for:

• 5+ years of experience developing system-level or device-resident software for macOS or Windows

  Experience developing background services (e.g., Windows Services, macOS launchd)
• Solid understanding of OS concepts: file systems, permissions, process lifecycle, and privilege boundaries
• A passion for and experience with security development best practices, coding standards, and design patterns
• Experience working in a remote-first company or distributed teams. You're self-driven, with excellent communication skills, and capable of managing your own time effectively.

Bonus points for:

• Experience with Linux system services
• Familiarity with software installation and update frameworks
• Experience designing resilient update and rollback mechanisms
• Experience designing secure client-server communication
• Experience as a Systems Administrator or Client Platform Engineer
• Experience troubleshooting production issues on customer devices

What you can expect:

• A remote-first environment where you'll have the freedom to work from anywhere, with a focus on asynchronous collaboration.
• Deep ownership of a foundational platform component
• Minimal meetings, allowing you the time and space to focus on solving complex authentication challenges.
• Opportunities to make significant technical contributions and lead impactful projects across 1Password's growing platform.
• A flexible work environment with the support of a passionate, collaborative team.
