Product Designer

We're hiring a Product Designer to help shape the product experience for Pi's agentic security platform at an early, pivotal stage. You'll work closely with product and engineering to turn complex security workflows — findings triage, root-cause investigation, remediation review, and prevention guardrails — into interfaces that feel fast, trustworthy, and obvious to use. This is a hands-on design role: you'll be in the details of interaction and visual design day to day, working across the product as it takes shape.

This role is 100% onsite at our San Francisco office. We're looking for someone who wants to build in person, alongside the founding team, during this stage of the company.

• Own product design for Pi's core surfaces — findings, investigations, remediation workflows, dashboards, and the Sloane assistant experience — from early concept through shipped detail.

• Turn dense, technical security and engineering context into interfaces that are fast to scan, easy to trust, and simple to act on, for both security teams and developers.

• Work directly with product and engineering to translate ambiguous product direction into concrete flows, prototypes, and polished UI.

• Design within and help extend the product's visual language and component patterns, partnering closely with frontend engineers who implement in React, and Next.js.

• Run discovery with customers and internal stakeholders — interviews, workflow shadowing, usability testing — to ground design decisions in how security and engineering teams actually work.

• Balance speed with rigor: ship quickly, but hold the line on clarity and trust for a product that security teams depend on.

• 3-5+ years of product design experience, including owning complex, workflow-heavy products end to end (not just marketing sites or simple CRUD apps).

• A portfolio that shows strong systems thinking — designing for information-dense, technical, or enterprise products where clarity and trust matter as much as visual polish.

• Fluency in modern interaction patterns for dashboards, tables, filters, detail views, and multi-step workflows.

• Comfort working directly with engineers on implementation details — you understand what's cheap and what's expensive to build, and you design accordingly.

• Strong prototyping skills (Sketch preferred, Figma or equivalent) and the judgment to know when a quick sketch is enough and when a high-fidelity prototype is needed.

• Experience running lightweight, fast research — customer interviews, usability tests — and translating findings into design decisions without slowing the team down.

• Comfort operating in a fast-moving, ambiguous startup environment, with the judgment to know when to move fast and when to slow down (especially given the security-critical nature of the product).

• Willingness and desire to work onsite in San Francisco full-time.

• Background designing for developer tools, security products, infrastructure, or other technical B2B products.

• Experience contributing to or evolving a design system.

• Familiarity with the frontend stack we build on (React, Next.js) or enough technical fluency to collaborate closely in it.

• Prior experience as an early design hire at a startup.

• Experience designing AI-assisted or agentic product experiences.

• Complex security workflows become simple, fast, and intuitive for the people who use them daily.

• Product surfaces are polished, consistent, and easy to extend as the platform grows.

• Design and engineering move in lockstep — new features ship without fragile or inconsistent UI.

• Customers and internal teams trust the product to guide them to the right action, not just show them data.

• The opportunity to be an early design hire with outsized ownership over product direction at a well-funded, fast-growing security startup.

• Competitive salary and meaningful equity.

• Work directly alongside the founding team, backed by top investors and security industry leaders.

• A San Francisco office and a team that believes in building together, in person.
