👉 We’re looking for a Senior Full Stack Engineer to own significant features end-to-end on our SaaS platform: the interface through which security teams discover, triage, and remediate vulnerabilities across their applications.

You’ll work in a squad of 4 engineers with a Technical Lead. Senior here means you drive technical decisions within your scope, mentor others, and ship autonomously. You won’t be pixel-pushing mockups: you’ll be deciding how to build things.

Context

• Location: Paris (75002), 2 days remote/week

• Company: Escape – Leading AI Cybersecurity Startup

• Cofounders: CEO (Tristan Kalos) and CTO (Antoine Carossio)

• Engineering Team: 15 Engineers, 4 Technical Leads, 2 Product Owner

What you will actually work on

• Building a product that stays fast at enterprise scale: You’ll ship UIs that remain snappy with large datasets: tens of thousands of assets/endpoints, millions of findings, complex faceted search, and real-time refresh.

• PostgreSQL & data performance that actually matters: Our product is data-heavy and latency-sensitive. You will work with advanced SQL functionalities : query design, indexing strategies, pagination, caching where it makes sense, and shaping data for GraphQL so the UI stays responsive.

• AI-native interfaces: We’re building workflows where AI meaningfully changes how security teams work: guided triage, assisted remediation, smart extraction of insights from noisy scans — all embedded into the product, with tight UX and reliability requirements.

• Security & developer workflows end-to-end: You’ll design and ship the experience from discovery → triage → remediation: risk scoring views, remediation journeys, and the integrations that make it real (webhooks, CI/CD, Git providers, ticketing).

• Architecture decisions that stick: We’re scaling fast and iterating weekly. You’ll influence both data modelling and system design — with a strong bias toward pragmatic, maintainable systems.

• Impactful changes: You won’t just implement tickets. You’ll take a problem from the customer’s pains to shipping solutions, measuring and mentoring others along the way.

Our Stack

• Frontend: Svelte + TypeScript, GraphQL (client)

• Backend: Node.js, GraphQL (Yoga + Pothos), Prisma, PostgreSQL, Kafka

• Infrastructure: AWS (FTR-certified), GitLab CI, Grafana

• Deep Tech (exposure, not required): Python (AI/ML), Go (network tooling)

• Compliance: We follow modern standards: comprehensive test coverage (unit, integration, E2E), Codecov, SOC-2 compliant processes. Code review is rigorous but not bureaucratic.

What we offer

• 💸 Equity: Significant BSPCE equity — we just raised at a strong valuation, and early engineering hires have meaningful upside

• ❤️‍🩹 Health first: Comprehensive health insurance with Alan

• 🍕 Meal vouchers with a Swile Card

• 💪 Sport subscription to have preferential prices to go to the gym, with Gymlib

• 📚 A place to learn and grow: Unlimited access to books and online courses to help you excel in your role

• 💻 Tech perks: Get the latest tech gear, including Apple (or not) equipment and ultra-wide screen, to do your best work

• 🎁 Open Source: Free time to work on cool Open Source Projects.

• 🌎 Global exposure: Present groundbreaking research at top international conferences, like APIDays (Paris, London, New York), BSides (Las Vegas, San Francisco, etc.) and RSAC (San Francisco), BlackHat and DEFCON (Las Vegas), etc.

Experience

• 5+ years building production web applications, with depth in both frontend and backend

• Strong TypeScript: not just “can write it” but actually leverages the type system

• GraphQL experience: you’ve designed schemas, not just consumed them

• Ownership mentality: you see a problem, you fix it, you don’t wait for permission

• Clear communication: can explain technical tradeoffs to non-technical stakeholders

Bonus points:

• Experience with Svelte (or willingness to ramp fast: it’s learnable in a week if you know React/Vue)

• Background in security, DevSecOps, or developer tooling

• Startup experience: you know what “shipping fast” actually means

We respect your time and will make it quick and efficient. The entire process will be completed within 1 week.
