    Job description


    • Our products are a set of tools that scan GitHub public activity and git private repositories for security vulnerabilities.

    • They are used by different teams: Software Development and Ops teams, Application Security, Threat Response and the buying decision comes from CISOs / CTOs / Directors of Security.

    • By design GitGuardian is a data driven company. Both co-founders are former Data Scientists and the first product of GitGuardian is real-time processing of all new GitHub events. Our secret detection engine has been battle tested against huge amounts of data.

    In this context, GitGuardian now wants to take it to the next level by incorporating Machine Learning models to create better vulnerability detectors and also improve internal performance efficiency. That’s why your work will matter and will be taken seriously !


    As a Machine Learning Engineer, you will have to:

    • Lead the end-to-end development of scalable and reliable Machine Learning models that can be used to solve business problems. For instance, build a new generation of secret detectors using state-of-the-art LLMs.

    • Identify areas in the company where Machine Learning can be applied. In particular, launch ML experiments to bring new in-app features to our existing products, like incident severity classification.

    • Deploy tools to monitor the quality and performance of the models, while ensuring that they meet the business requirements

    • Work closely with the Data Engineering team to ensure smooth data integration

    • Collaborate with DevOps and Software Engineering teams to deploy models into our products, monitor their performance, and troubleshoot issues as needed

    • Stay up-to-date with the latest advancements in NLP and ML technologies to implement new techniques into the existing models and foster a culture of innovation and continuous learning

    • Communicate about cutting-edge ML applications at GitGuardian by writing blog posts, participating in meetups


    • You will build and deploy state-of-the-art models that bring high value to the business

    • You will be able to leverage a huge amount of textual data collected from day 1
