Description complète du poste

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: Fullstack oriented Design, Frontend-end

We are seeking a Senior Front-end with background in Design 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

Interview Process (1 week, streamlined)

HR Chat: 30 min
Coding Interview (full stack): 60 min
Frontend/UI/Product Deep Dive: 60 min
Leadership Interview with CTO: 30 min
Final Interview with CEO: 30 min
