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.
