Security Researcher Mid-level
We are seeking a Security Researcher – Mid-level to join Escape and play a central role in advancing the detection capabilities of our DAST and ASM products.
This is an applied security role: think web pentester with strong coding skills . Your mission is to turn offensive security knowledge into scalable, production‑grade detection logic.
You will focus on discovering new vulnerability detection techniques, improving existing algorithms, and ensuring Escape remains best‑in‑class in terms of accuracy, performance, and real‑world relevance.
As part of the Security Research team, you will transform security insights and exploitation techniques into concrete detection logic that runs at scale in production. Your work will directly shape the effectiveness of Escape’s scanners and have a measurable impact on customer security outcomes.

Company : Escape – Leading AI Cybersecurity Startup
Cofounders : CEO (Tristan Kalos ) and CTO (Antoine Carossio )
Engineering Team : 15 Engineers, 4 Technical Leads, 1 Product Owner
Team Size : You’ll be working in a close‑knit team of 3 outstanding engineers under the supervision of a technical lead
Key Responsibilities
Vulnerability Research: Identify new classes of vulnerabilities across web applications, APIs, and modern architectures, and reproduce real‑world exploitation techniques.
From Exploit to Detection: Translate manual attack techniques into scalable automated detection logic, designing payload strategies and validation heuristics.
Algorithm Design & Improvement: Continuously improve detection algorithms with a strong focus on accuracy, signal quality, and reduction of false positives and false negatives.
Applied R&D: Turn research ideas into practical, production‑ready detection logic suitable for large‑scale automated scanning.
Performance & Accuracy Focus: Optimize trade‑offs between coverage, noise, scan duration, and infrastructure cost to ensure scanners remain efficient at scale.
Cross‑Team Collaboration: Work closely with Scanners and Platform teams to integrate research outputs into distributed production systems.
Technology Watch: Monitor emerging vulnerabilities, CVEs, and offensive research to continuously raise Escape’s detection capabilities.
Tech Stack
Languages: Compiled languages (Go, Rust), scripting languages (Python) for prototyping
Research Focus: Vulnerability discovery, detection algorithms, and performance‑oriented analysis
Execution Context: Research outputs integrated into large‑scale automated scanners
Collaboration Surface: Close interaction with production systems and distributed scanning workloads
Engineering Focus: Accuracy, performance, and applicability of detection logic at scale
