Fullstack Engineer | AI Pentesting

We're Escape, YC-backed, Series A, growing 15%+ month-over-month. Our AI-powered platform does automated penetration testing for companies like Zoom, Air France-KLM, Vanta, and Miro. We find vulnerabilities before attackers do.

• Location: Paris (75002), 2 days remote/week
• Cofounders: CEO (Tristan Kalos) and CTO (Antoine Carossio)
• Team: 15 engineers. Weekly shipping. Real autonomy. If you want to level up fast, this is the place.

Why this role?

Most mid-level roles put you on a feature assembly line. This one won't.

You'll join a squad of 4 engineers with a Tech Lead who'll help you grow: but you'll ship real features to real enterprise customers from week one. You'll touch the full stack, work on hard problems, and see your code in production every day.

What you will actually work on

• Build product at enterprise scale: UIs that stay fast with tens of thousands of assets and millions of findings. You'll learn what "scale" actually means in practice.
• Get deep on data: PostgreSQL performance, query optimization, indexing. Our product is data-heavy. You'll develop real backend skills, not just API plumbing.
• Ship AI-native features: guided triage, assisted remediation, smart insights from security scans. AI is core to the product, and you'll build the interfaces around it.
• Own features end-to-end: from database schema to UI component. No artificial frontend/backend split.
• Work with security teams: you'll understand how enterprises find and fix vulnerabilities. Domain knowledge that's increasingly valuable.

Stack

• Frontend: Svelte + TypeScript, GraphQL client
• Backend: Node.js, GraphQL (Yoga + Pothos), Prisma, PostgreSQL, Kafka
• Infra: AWS, GitLab CI, Grafana
• Deep tech: Python (AI/ML), Go (network tooling)

SOC-2 compliant. Rigorous code review. Comprehensive test coverage. You'll learn engineering best practices, not just how to code.

Experience

• 3+ years building production web apps (internships don't count, side projects do)
• Solid TypeScript: you're comfortable with the type system, not fighting it
• Fullstack curiosity: you don't want to be "just frontend" or "just backend"
• You ship: you've put things in production and dealt with what happened next
• You learn fast: more important than checking every box on a stack list

Bonus: GraphQL experience · Svelte/React/Vue · Interest in cybersecurity · Startup experience

What we offer

• 💸 €55K–75K base salary, based on experience
