Job Summary


As a Product Engineer based in Paris, you’ll work closely with the founders, engineering, design, and product teams by building customer-facing, AI-powered security products from the ground up. You’ll be a key player in enabling the mission to make application security invisible by leveraging LLMs and agentic systems. This is a high-impact, product-driven role that combines deep technical ownership with a fast-paced, iterative mindset.

Required Skills and Qualifications


  • Design and build customer-facing features in collaboration with product, design, and real users—shipping fast and learning constantly.
  • Take full ownership of features and systems, from architecture and implementation to deployment and iteration.
  • Engage directly with users over Slack or calls to gather feedback and shape the product around real-world usage.
  • Work at the frontier of LLMs and agentic systems to accelerate development and tackle vulnerability management in novel ways.
  • Champion high-quality engineering practices: well-tested code, fast CI pipelines, and strong observability.
  • Contribute to product direction and help shape the overall technical and cultural foundations.

Tech Environment


  • Likely tools and frameworks: TypeScript/React, Python, Node.js, LangChain, OpenAI, vector databases, modern CI/CD, and observability tools.
  • Strong preference for experience or active interest in LLMs, agentic architectures, and developer/security tools.

In return, they offer


  • A chance to work at the intersection of security and AI, helping shape the future of both industries.
  • An early role in a high-talent, globally ambitious team backed by leading VCs and tech executives.
  • Competitive salary, meaningful equity, and full benefits.
  • Full-time, onsite collaboration in Paris with an English-speaking team building for a global market.
  • A culture that prioritizes ownership, innovation, speed, and thoughtful engineering.
