Build the future of AI-powered DevSecOps.

Symbiotic Security merges Cybersecurity and AI to help developers write secure code. We are looking for an AI Engineer (Junior to Mid-level) to join our Paris team and turn every vulnerability into a learning opportunity.

🚀 The Challenge: No isolated research labs here. You will join a "Product Engineering" organization where AI is the heart of the product. Your goal is to build a seamless assistant that doesn't just find bugs, but fixes them and teaches the dev how to avoid them next time.

🔧 What you will do:

  • Core Product Development: Design and ship AI features that detect and remediate security flaws in real-time within the IDE and CI/CD pipelines.
  • GenAI Protection: Build systems to specifically catch and fix vulnerabilities introduced by tools like GitHub Copilot.
  • Data Strategy: Generate and curate high-quality synthetic datasets (good/bad code samples) to train and refine our assistant.
  • Evaluation Frameworks: Build and maintain rigorous testing pipelines—because we only improve what we can measure.
  • Production Excellence: Move rapidly from PoC to production-grade features alongside our CTO and backend team.

🛠️ Your Daily Stack:

  • Backend & AI: Python 3.12, AWS Bedrock, LangChain, LLM proxy.
  • Environment: PostgreSQL, AWS, Hexagonal Architecture.

🎯 Your Profile:

  • Solides bases en Python et software engineering (Clean Code, Testing).
  • Hands-on experience with LLMs (RAG, agents, systematic evaluation).
  • Engineering degree or strong scientific background (Top Schools).
  • Languages: Full professional proficiency in both English and French is required.

💎 Why join us?

  • Impact: Join a multidisciplinary team (AI, Cyber, DevExp) where you will constantly learn from experts in different fields.
  • Mentorship: Work directly with Salah Eddine (AI Engineer) and Edouard (CTO, ex-VP Product GitGuardian).
  • Rituals & Culture: Dive into our CTFs, Bug Days, Internal Hackathons, Tech Tuesdays, and our annual Company Retreat.
  • Growth: Standard equity (BSPCE) + 100% Health Insurance + 2 days remote/week.
  • Location: Vibrant offices at Morning Laffitte (Paris 9th).
