Apply: https://jobs.ashbyhq.com/escape/2384716d-587f-4ff2-a7e9-dd8557e49920

## About Escape

Replace legacy scanners and manual offensive security processes with AI agents that discover, test, and remediate directly in your engineering workflows.

## About the role

**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 (18 engineers, 4 technical leads, 3 product owners) is dedicated to redefining application security with cutting-edge detection and automation. Led by CEO Tristan Kalos and CTO Antoine Carossio, 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

- 🎁 Dedicated time for open-source projects

- 🌍 Present research at top international conferences (RSAC, BlackHat, DEFCON, BSides, APIDays)**About You**

- 4+ years of experience in backend engineering, security research, or applied R&D in a product environment

- Strong software engineering fundamentals and ability to work across domains (systems, networking, web architectures)

- Proficient in at least one backend language (Python, Go, or similar)

- Experience designing and shipping production systems with measurable impact

- Ability to translate complex ideas or research into reliable, scalable implementations

- Strong analytical mindset, with a focus on pragmatism and impact

- Comfortable collaborating across engineering and security to deliver end-to-end solutionsNice to have:
