Lead Security Researcher

We are seeking a Lead Security Researcher to join Escape and play a central role in advancing the detection capabilities of our DAST and ASM products.

This role focuses on applied research: discovering novel 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 work on transforming security insights 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.

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, 1 Product Owner
• You’ll be working in a close‑knit team of 3 outstanding engineers under supervision of a technical lead.

Key Responsibilities

• Vulnerability Research: Research and identify new classes of vulnerabilities and novel detection techniques across web applications, APIs, and modern application architectures.
• Algorithm Design & Improvement: Design, evaluate, and continuously improve detection algorithms with a focus on signal quality, performance, and reduction of false positives.
• Applied R&D: Turn research ideas into practical, implementable detection logic suitable for large‑scale, automated scanning.
• Performance & Accuracy Focus: Evaluate trade‑offs between coverage, accuracy, and execution cost to keep scanners efficient at scale.
• Cross‑Team Collaboration: Work closely with the Scanners and Platform teams to ensure research outputs are effectively integrated into production systems.
• Technical Leadership: Act as a senior contributor within the research team, setting technical direction, reviewing research approaches, and mentoring other researchers.
• Technology Watch: Stay up to date with emerging vulnerabilities, exploitation techniques, and defensive research in the application security ecosystem.

Tech Stack

• Languages: Compiled languages (C/C++, Go, Rust) and scripting languages 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.

Perks

• Significant equity (Stock Options/BSCPE), making you a true stakeholder in our success.
