**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

**Perks & Benefits**

- ❤️‍🩹 Top-tier health insurance with Alan
- 🍕 Meal vouchers with Swile
- 💪 EGYM Wellpass sport subscription
- 📚 Continuous learning: budgets for books and online courses
- 💻 Premium equipment to support your work
- 🎁 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 solutions

Nice to have:

- Experience in application security (web security, pentesting, bug bounty, etc.)
- Exposure to AI/LLM-based systems
- Familiarity with browser automation or large-scale distributed systems
