Teams at Pi Security

Own end-to-end product design for complex security, investigation, remediation, and prevention workflows. Partner with product and engineering to shape direction, conduct customer research, build trustworthy AI-assisted experiences, and translate technical security context into clear interfaces. Extend the design system, collaborate with frontend engineers, lead critiques, and ensure quality through implementation and release. The role is onsite in San Francisco and requires strong interaction design, visual craft, systems thinking, and experience with complex B2B or technical products.

Design, develop, and scale Pi’s core platform, including backend systems, shared services, internal APIs, frameworks, and abstractions for authentication, authorization, multi-tenancy, asynchronous jobs, and service communication. Improve system architecture, reliability, performance, and maintainability while collaborating with product, AI, and infrastructure teams to solve shared engineering challenges.

Lead security research from hypothesis through production, developing LLM- and program-analysis-based vulnerability detection, triage, and remediation capabilities. Design datasets, benchmarks, and evaluation pipelines; investigate vulnerabilities across cloud, containers, microservices, APIs, and LLM applications; build the vulnerability and remediation corpus; and partner with engineering to ship validated product features. Set the research agenda, maintain quality standards, publish findings, and communicate security insights to technical and business audiences.
