Product Designer

About the Role

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.
What You'll Do

• 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.

What We're Looking For

• 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.

Nice to Have

• 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.

Success In This Role Looks Like

• 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.

What We Offer

• 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.
