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. No feature factories.

What you'll own

You'll join a squad of 4 engineers with a Tech Lead. "Senior" here means you drive decisions, not implement tickets. Concretely:

• Ship product that works at enterprise scale : tens of thousands of assets, millions of findings, complex search, real-time refresh. You'll make it stay fast.
• Solve hard data problems : PostgreSQL performance, query design, indexing strategies, pagination, caching. Our product is data-heavy and latency-sensitive. This isn't CRUD.
• Build AI-native workflows : guided triage, assisted remediation, smart extraction from noisy scans. AI is embedded into the product, not bolted on.

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. Not bureaucratic.

What's in it for you

• €80K–105K base salary, based on experience

Experience

• 5+ years shipping production web apps, strong on both frontend and backend
• TypeScript fluency : you actually leverage the type system, not just tolerate it
• GraphQL depth : you've designed schemas, not just consumed them
• Ownership mindset : you see a problem, you fix it, you don't file a ticket and wait
• Clear communicator : can explain tradeoffs to non-technical stakeholders

Bonus: Svelte experience · Security/DevSecOps background · Startup DNA
