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 hiring a Principal Engineer to define the technical direction for AI-powered security capabilities in 1Password. This is a senior individual contributor role for an engineer who can translate a high-stakes problem space into production systems. You will set the architecture, technical standards, and operating model for how AI is used in security-sensitive product experiences. The work spans client, service, and policy layers and must meet a high bar for privacy, auditability, reliability, and user trust. This is not a research role. It is not a prototype lab. The expectation is production-grade systems that can operate under enterprise scrutiny, adversarial conditions, and real-world performance constraints. This is a greenfield opportunity with genuine stakes. You'll define the reference architecture, set the engineering bar, and own the path from prototype to production for a capability area that will shape the company's trajectory for the next five years. The constraints here (privacy-preserving by default, on-device where possible, auditable always) aren't limitations: they're the design surface that makes the problem interesting and the outcomes defensible. If you want to build AI systems that matter, that operate under real-world trust requirements, and that will be used by people who depend on them, this is that role. AI will change both how attacks happen and how security products respond. At 1Password, we have the opportunity to apply AI at a high-signal point in the identity and credential flow, where better decisions can meaningfully improve security outcomes for end users and businesses. This role will help determine whether we do that with the engineering rigor and trust model our customers expect. This is a remote opportunity within Canada and the US. What we're looking for: - You have built and operated production systems where trust, correctness, and failure handling matter. - You have deep experience with AI or ML systems in production, ideally including LLM-integrated systems with explicit guardrails, evaluation pipelines, auditable tool use, and clear limits on autonomous behavior. - You have strong instincts for privacy-preserving design, including client-side or edge inference, constrained telemetry, explainable system behavior, and predictable user-facing outcomes. - You have meaningful depth in security-sensitive domains such as identity, authentication, authorization, secrets management, enterprise controls, endpoint trust, or adversarial detection. - You have a track record of setting technical directi ...
