Senior Machine Learning Engineer

GitGuardian is a global post-series B cybersecurity startup; we’ve raised $44M by the end of 2021 with American and European investors including top-tier VC firms.

More than ever in 2023, we have a very solid business model with a fast-growing ARR, multi-year contracts and great customer retention rates.

Among our early investors who saw our market value proposition, are the co-founder of GitHub, Scott Chacon, along with Docker co-founder / CTO Solomon Hykes 👀

We develop code security solutions for the DevOps generation and are a leader in the market of secrets detection & remediation.

Our solutions are already used by hundreds of thousands of developers in all industries and GitGuardian Internal monitoring is the n°1 security app on the GitHub marketplace 🔥

We work with some of the largest IT outsourcing companies, publicly listed companies like Talend or tech companies like Datadog.

More than 85% of our customers are in the United States.

Context

• 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 !
