Job Description

Global Product Security's Ethical Hacking Team is responsible for performing in depth security assessments across Oracle's entire product and service portfolio. Over the years, the EHT has built a suite of pioneering security tools used for vulnerability triaging and identification: you will be responsible for their maintenance, improvement and growth, with particular attention to simplicity and usability for the end users.

You will be working closely with our software engineers spread across Oracle worldwide. Your contribution will add vital pieces to the foundations on top of which Oracle constantly improves security for users and clients.


You will be the main responsible person for all our security tools, written in Java, Python and Bash; you will maintain, update and enhance the codebase. You will embed cutting-edge security research techniques in the tools, by reading academic papers and implementing relevant content. You will be responsible for support to end users (bug fixing and enhancement requests) as well as producing documentation, presentations and reports on tools usage, highlighting success cases and ROI.

The EHT is not your run-of-the-mill pentesting gig, we're not only invested in finding bugs but also making sure they are fixed correctly and don't happen again. We need people who can use their skills and share their expertise to effect meaningful change across the company. Along the same lines, being able to describe the impact of a CVSS 10 bugs in terms your audience (both technical and non-technical) will understand, is essential.

A successful candidate must have genuine excitement for and interest in security, as well as the desire to share knowledge and help others learn from the high technical and ethical standards you set. You will learn from the rest of the EHT during real security assessments, and gather expertise on the attack techniques that will sharpen your skills in security testing and you will re-use to improve out tools. Your work will benefit thousands of Oracle engineers worldwide and shape the future of product security within one of the largest software companies in the world.
