About Escape

Escape is transforming offensive security for resource‑constrained teams. We build AI agents that identify and exploit vulnerabilities in modern applications, APIs, and microservices—mimicking real attackers, but operating at CI pipeline speed.

We are a Y Combinator W23 company with an $18M Series A (March 2026) led by Balderton Capital, with Uncorrelated Ventures, IRIS, and YC participating. Trusted by leaders like Zoom, Schibsted, Wiz, and Pandadoc, we’re scaling from 40 to 80 people across Paris and NYC.

The Role: Product Design Engineer, Frontend

We are seeking a Senior Product Engineer to steward the frontend craft of Escape’s SaaS product. This role goes beyond simple implementation: you’ll transform complex cybersecurity workflows into fast, elegant, and intuitive experiences.

• Design UIs for asset inventory, attack surface exploration, scan configuration, AI pentesting, dashboards, reporting, and more
• Simplify dense, technical, and data‑heavy product surfaces

Frontend Architecture & Components

• Develop reusable, scalable UI components and improve overall frontend architecture
• Maintain consistency, performance, and responsiveness across the product
• Keep the codebase clean, typed, tested, and maintainable

Design System

• Evolve Escape’s design system: component patterns, layout, forms, tables, navigation, accessibility, and visual consistency
• Move quickly from concepts to production code, leveraging tools like Claude Design, v0, and Figma

Backend Integration

• Integrate with GraphQL APIs, manage TypeScript types, data fetching, pagination, filtering, mutations, and API contracts
• Collaborate closely with backend engineers and proactively drive schema discussions

Success in the Role

After 3 months

• Shipped impactful product improvements and migrated the SaaS app toward a new design system
• Met key customers to build strong workflow intuition, driving product enhancements
• Improved component quality and UI consistency
