Senior Backend Engineer

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: PostgreSQL, S3-compatible object storage, Redis (limited use)
-
Messaging: Kafka
-
Observability: OpenTelemetry, Grafana Cloud
-
CI/CD & Infra: GitLab CI, Terraform
