About Escape
Join Escape, a fast-growing leader in AI-powered cybersecurity. Our mission-driven engineering team (18 engineers, 4 technical leads, 3 product owners) is dedicated to redefining application security with cutting-edge detection and automation.
We operate at the forefront of technology and research from our Paris office.
About the Role
As a Senior Backend Engineer you will work in a team with talented security researchers. You'll champion innovation, and ensure research translates into impactful production solutions.
What You'll Do
•
Agentic scanning systems
Build systems that autonomously explore applications, maintain context, and execute complex testing strategies.
•
Security detection engine
: Design and implement reliable, production-grade vulnerability detection logic (injection, auth issues, business logic flaws, etc.).
•
AI-driven testing
Integrate LLMs and structured reasoning into scanning workflows to improve coverage and reduce false positives.
•
Distributed infrastructure
Work on systems that orchestrate thousands of concurrent scans (Kubernetes, queues, resource management).
•
Performance & reliability
Ensure scans are fast, deterministic, and cost-efficient despite high complexity and concurrency.
•
Core platform design
Contribute to architecture decisions around memory systems, execution environments, and data models.
Our Tech Stack & Focus
•
Languages
Python (primary), Go (performance/network components)
•
Runtime
Containerized workloads on Kubernetes (EKS), supporting long and resource-intensive scans
•
Scaling
Kubernetes Jobs & queue-driven autoscaling
•
Web Automation
Playwright + headless Chromium
•
Data
