1Password is a market-leading enterprise password manager and Unified Access Management platform trusted by over 180,000 businesses, from Fortune 100 companies to innovative AI firms. The company has surpassed $400M in ARR and has been on the Forbes Cloud 100 for four consecutive years. The Filling & Saving team builds and maintains the core experience for filling and saving data online, setting the standard in password management and building unified sign-in capabilities across platforms. This role offers the opportunity to work with Product, Design, and QA teams internally as well as the open-source community to advance the filling and saving experience. 1Password is thoughtfully integrating AI across the full software and product development lifecycle. Engineers use AI-assisted coding tools to accelerate reviews and catch bugs earlier, while maintaining clear principles, human accountability, and rigorous evaluation before anything ships to customers. In this role, you will code, test, debug, deliver, and maintain production software systems for new and existing product features. You'll collaborate with cross-functional teams throughout the development cycle to ensure smooth releases. You'll mentor junior and new team members by providing technical guidance, sharing knowledge, and engaging in pair programming. You'll participate in planning by identifying major tasks, breaking down work, and estimating timelines. You'll write comprehensive tests during various stages of the development cycle and review code to maintain high quality and support a safe feedback environment. You'll generate and review documentation on code processes to ensure scalability, stay informed about industry trends and best practices, and be available for on-call rotational work to resolve emergencies. 1Password prioritizes collaboration, clear communication, receptiveness to feedback, and alignment with core values: keep it simple, lead with honesty, and put people first. The work is demanding, the pace is fast, and the company seeks individuals who are proven experts, highly adaptable, curious, and driven to make an impact. Remote work is part of 1Password's DNA since its founding in 2005. However, travel for in-person engagement is expected, including annual department-wide offsites, team meetings, and customer/industry events. Frequency depends on role and responsibilities. Remote work at 1Password means working from your home country.
