Jobs 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.

Own the roadmap and lifecycle for Pi.Security’s agentic product security platform. Conduct customer discovery, define product requirements and trust standards for autonomous agents, evaluate model quality, shape integrations with developer workflows, prototype with AI coding tools, and establish scalable product practices. Partner with engineering, security researchers, sales, marketing, founders, and enterprise customers to drive adoption, retention, and measurable customer outcomes.

Build and maintain scalable AI agents, pipelines, and services; improve infrastructure for running, evaluating, and monitoring agents; collaborate with product and security teams on AI-powered security features; and evaluate emerging LLM and agent technologies for product use.

Leads Pi Security’s engineering organization and technical execution at an early-stage security startup. Responsibilities include owning the engineering roadmap, making architectural decisions, writing and reviewing code, hiring and mentoring engineers, establishing scalable engineering practices, and guiding backend, AI/ML, integrations, and security-focused platform development. The role partners with founders and customers and is fully onsite in San Francisco.

Own product positioning, messaging, competitive intelligence, field enablement, and go-to-market support for Pi’s cybersecurity platform. Translate complex product capabilities into compelling customer-facing content, support launches, engage directly with customers and prospects, and help define the product security category. Partner cross-functionally with product, sales, customer success, and technical teams in a hands-on startup environment.
