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.

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 direction across multiple teams, making durable architecture decisions, and driving delivery through complex dependencies.

• You communicate clearly with engineers, executives, and cross-functional partners. You can explain hard tradeoffs plainly and make good judgment legible.

• You have built and operated production systems where trust, correctness, and failure handling matter.

Bonus points for:

• Experience with endpoint or device posture signals, browser or extension security, phishing detection, or enterprise device trust.

• Experience with SaaS administration, identity lifecycle workflows, or enterprise policy automation.

• Experience building evaluation, red-team, or abuse-testing frameworks for AI-assisted systems.

What you can expect:

• You will set the rules for where model-based reasoning is appropriate, where deterministic systems must take over, and how those layers interact safely in production.

• You will define the standards for signal collection, aggregation, retention, and use. That includes making clear decisions about what happens locally, what happens remotely, and what should not be collected at all.

• You will design the control model for agentic and tool-using systems in product contexts, including permission boundaries, approval paths, audit logs, rollback behavior, and safe fallback under uncertainty.

• You will establish the platform primitives that let teams build AI features consistently and safely, including interfaces for model invocation, policy evaluation, tool execution, experimentation, telemetry, and evaluation.

• You will make key architecture calls on where 1Password should build differentiated capability, where it should integrate with adjacent systems, and where it should stay opinionated about scope.

• You will work with Security, Privacy, Legal, and Compliance early in the design process so that trust, regulatory, and data-handling requirements are built into the architecture from the start.

• You will raise the operational bar for AI in production by defining service expectations, evaluation frameworks, rollout controls, rollback paths, abuse testing, and incident playbooks.

• You will lead through technical judgment and influence across teams. This role is expected to shape direction well beyond any single codebase.
  

What success looks like:
Success in this role means 1Password can ship AI-powered security capabilities that are effective, measurable, and worthy of customer trust.

That includes:

• Meaningful reduction in credential-related risk patterns

• Faster and safer response when risk is detected

• High admin confidence in AI-assisted controls and recommendations

• Product experiences that reduce friction instead of introducing opaque automation

• Clear evaluation and observability standards that let teams improve systems without weakening safety, privacy, or reliability
