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

- 💸 Significant equity (Stock Options/BSPCE) – become a core stakeholder in Escape’s journey

- ❤️‍🩹 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

-

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
