Junior Full-Stack Engineer (Product & Platform) – Paris Office

Location: Paris (75002), 2 days remote per week

Company: Escape – Leading AI Cybersecurity

Compensation: 55-75k + 0.05% BSPCE (stock options)

Our Team: 21 Engineers, 4 Technical Leads, 4 Squads

About Escape

Escape is offensive security for the teams that are 100x outnumbered. We build AI agents that find and exploit vulnerabilities in modern applications, APIs, and microservices: the way a real attacker would, but at the speed of a CI pipeline.

We're a Y Combinator W23 company. We just closed an $18M Series A in March 2026 led by Balderton Capital (with Uncorrelated Ventures, IRIS, and YC following on). Our customers and partners include Zoom, Schibsted, Wiz, Pandadoc, and a growing list of teams who've stopped pretending annual pen tests are enough. We're 40 people split between Paris and NYC, scaling to 80 in the next 12 months.

The product surface is real: ASM, business-logic-aware DAST, and AI Pentesting GA-ing this year. The competitive thesis is that LLMs collapsed the cost of offensive engineering by 1000x, and the companies that ship that capability into production first will own the next decade of the category. We're betting we're those companies.
