is the next-generation digital identity wallet that simplifies how individuals securely prove their identity online. Consumers can verify their identity with  once and seamlessly login across websites without having to create a new login and verify their identity again. Over 152 million users experience streamlined login and identity verification with  at 20 federal agencies, 45 state government agencies, and 70+ healthcare organizations.

More than 600+ consumer brands use  to verify communities and user segments to honor service and build more authentic relationships. 's technology meets the federal standards for consumer authentication set by the Commerce Department and is approved as a NIST 800-63-3 IAL2 / AAL2 credential service provider by the Kantara Initiative.  is committed to "No Identity Left Behind" to enable all people to have a secure digital identity.

is a full-time, in-office culture. Unless a specific job description explicitly states otherwise, all roles are on-site five days per week at one of our offices in McLean, VA;
Mountain View, CA;
New York City, NY; or Tampa, FL. Certain roles — such as field-based sales or other remote-by-design positions — may have different work arrangements as noted in their individual postings.

At , we embrace the thoughtful use of AI tools in our daily work and there are even occasions where we leverage AI in our hiring process. However, during the interview process, we want to understand your individual skills and experiences. Therefore, we have guidelines on how AI can be appropriately used during your application and interviews which can be found here.

This Staff Engineer role sits at the intersection of engineering, applied AI, testing and developer experience. You will define and lead the discipline of testing AI agents, evaluating LLM behavior, and ensuring the reliability of agentic systems operating in production. It requires deep engineering rigor, original thinking about what "correctness" means for non-deterministic systems, and the ability to build eval infrastructure and developer tooling that the entire engineering org depends on.

Expert in building and maintaining Retrieval-Augmented Generation (RAG) pipelines, with a deep focus on strategic data chunking and data quality enforcement. Experience in establishing pre-retrieval data quality gates to optimize vector search accuracy, minimize retrieval-induced noise, and significantly reduce LLM hallucination rates in production-deployed agent systems.

You will establish quality standards for how  ships AI-powered features safely, mentor engineers across teams on AI testing best practices, and partner directly with product and platform teams to embed quality into every stage of agent development.

• Define AI Quality Standards: Own the framework for how  evaluates, validates, and monitors AI agents — from prompt-based features to fully autonomous multi-step workflows.
• Build Eval Infrastructure: Design and maintain evaluation pipelines for LLM outputs, agent behavior, tool use, and multi-turn interactions across development, staging, and production environments.
• Production Observability for Agents: Instrument agentic systems for behavioral drift, regression, and failure modes that traditional metrics miss — latency, correctness, hallucination rate, tool misuse, and policy adherence.
• Agentic Test Strategy: Lead the design of test suites that handle non-determinism — red-teaming agents, golden dataset construction, LLM-as-judge pipelines, and property-based testing for AI outputs.
• Champion Developer Experience: Build the internal tooling, feedback loops, and testing workflows that make it fast and safe for engineers to develop and ship AI features with confidence. Reduce friction in the agent development inner loop — local testing, fast eval runs, and clear signal on regressions.
• Drive AI-First Engineering Culture: Raise the quality bar across the engineering org by establishing patterns, tooling, and education for how teams write, test, and deploy AI features…
