We're Escape, YC-backed, $18M 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: 18 engineers. Daily 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.
Own the full journey: from vulnerability ingestion → triage → remediation. Risk scoring, developer integrations (CI/CD, Git, ticketing), the whole loop.
Shape the architecture: data modelling, system design, GraphQL schema. You'll influence how we build, not just what.
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.
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
What's in it for you
€70K–100K base salary, based on experience
Meaningful equity (BSPCE): you're joining a rocketship post-Series A, pre-scale
Real impact: you'll talk to customers, see your work in production weekly, influence product direction
Conference speaking: we send engineers to RSAC, BlackHat, DEFCON, BSides (NYC, Vegas, SF, London, Paris)
Growth path: Tech Lead track is open and real, not theoretical
Health (Alan), meals (Swile), sport (EGYM Wellpass), top-tier equipment, open-source time
