Product Designer

Pi Security•San Francisco, CA

2d•Onsite

About The Position

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.

Requirements

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 Haves

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.

Responsibilities

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.
