Design Engineer (Front-end)

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.

A Y Combinator W23 company, we recently closed 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, Escape is helping teams move beyond traditional annual penetration testing. Now 40 people between Paris and NYC, we’re scaling to 80 in the next year.

Our product surface spans ASM, business-logic-aware DAST, and AI Pentesting, all going GA this year. Our competitive thesis: LLMs have reduced the cost of offensive engineering by 1000x—and those who deliver it to production first will shape the decade ahead. We’re committed to leading that charge.

The Role: Product Design Engineer, Frontend

We are seeking a Senior Product Engineer to steward the frontend craft of Escape’s SaaS product. This is neither a simple implementation nor a passive pixel-pushing role.

You will join the SaaS/Web Development Team, acting as a key bridge with Product. Your focus: transform complex cybersecurity workflows into fast, elegant, and intuitive product experiences. You’ll deeply understand customer problems and design, build, and ship interfaces that make sophisticated processes feel simple.

What We’re Looking For

Strong product judgment and taste

Advanced frontend engineering skills

Ability to design and build reusable component systems

Solid backend understanding for independent API integration

A keen eye for visual and interaction details ("le compas dans l’œil")

What You’ll Own

Product Experience

Build and iterate on Escape’s core SaaS app for vulnerability discovery, testing, triage, and remediation

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
