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

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

After 6 months:

• Taken ownership of major product surfaces

• Enhanced the design system and reusable components

• Accelerated team velocity through improved UX patterns

• Trusted to interface directly across functions and ensure production quality

After 12 months:

• Elevated Escape’s SaaS product to new levels of polish, consistency, and scalability

• Set the frontend engineering quality standard

• Built product experiences supporting enterprise scale

Our Stack

• Frontend: Svelte, TypeScript, GraphQL client

• Backend: Node.js, GraphQL, Prisma, PostgreSQL, Kafka

• Infra: AWS, GitLab CI, Grafana

• Deep Tech: Python (AI/security engines), Go (network tooling)

• Product/Design: Figma, Claude Design, or similar AI tools

• SOC 2 compliant, rigorous code reviews, and strong testing culture

You Might Be a Fit If You Have

• 5+ years’ experience shipping production web applications

• Strong TypeScript and frontend architecture skills

• Experience building and maintaining component/design systems

• Comfort with GraphQL or similar API layers

• Autonomy in integrating with backends

• A customer-first and product-quality mindset

You Care Deeply About

• Customer feedback and polished products

• Visual hierarchy, spacing, accessibility, performance, consistency

• Developer experience and product clarity

Bonus Points

Not required, but valued:

• Svelte experience

• Cybersecurity/DevSecOps exposure

• Building data-heavy B2B SaaS products and design systems

• Familiarity with AI-assisted design tools

• Fast-growth startup experience or light backend contributions

What’s In It for You

• €70K–100K base salary depending on experience

• Meaningful equity through BSPCE

• True product ownership and customer impact

• Exposure to product strategy and real customer feedback

• Opportunities for growth toward Staff Engineer, Tech Lead, or Product Engineering leader roles

• Conference participation (RSAC, Black Hat, DEF CON, BSides, etc.)

• Health insurance (Alan), meals (Swile), sport (EGYM Wellpass), top-tier equipment, and open-source contribution time
