## Description

**Location:** Paris (75002) | Hybrid (2 days remote/week)

**About Escape**
Join Escape, a fast-growing leader in AI-powered cybersecurity. Our mission-driven engineering team (21 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 Research 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
