Browser Extension Excellence owns the foundation that supports 1Password’s browser extension, our most-frequently used client surface. This includes architecture, health monitoring, build and test pipelines, developer tooling, cross-browser compatibility, and setting new standards within the WECG. We investigate production incidents, improve load and runtime performance, and guide the extension through changes such as Manifest V3 and browser version deprecations.

This is a remote opportunity within Canada/US. This position will be for 4 months - January to April 2027.

• Teamwork: We work together, and succeed as a team!

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.
