Machine Learning Engineer

Passionate about building and deploying innovative machine learning solutions?

Join Hadrian and take the lead in shaping our ML infrastructure to transform cybersecurity automation!

Who are we:

We are Hadrian - a cybersecurity startup. A force reshaping the future of cybersecurity. Founded in August 2021, we've secured €20 million in funding and the backing of ABN AMRO Ventures, propelling us into a new era.

Our goal is to provide companies with a real-time Exposure Management platform, viewing security through a hacker's eyes because, well, hackers understand hackers best. We continuously map the digital footprint of organizations, discover risks, and prioritize remediation for security teams to harden their external attack surfaces.

Located in Amsterdam's buzzing Leidseplein and by London's famous Paddington station, our diverse team from 20+ countries is on a mission to revolutionize security. Join us in securing over 200 businesses and be at the forefront of automated offensive security.
