Git Hub is changing the way the world builds secure software and we want you to help change the way we secure Git Hub. Git Hub’s Red Team is an active threat emulation team that models real world threats and executes simulated attacks targeting Git Hub. We’re looking for an offensive security engineer to expand Git Hub’s Red Team operations.

In this role you will execute both red and purple flavored offensive operations, deliver results to key stakeholders through written reports and live briefings, and partner with product teams for remediation. You’ll also provide a vital offensive perspective to many security-wide initiatives including threat modeling, table tops, and adversarial analysis. You’ll also work closely with the detections, IR, and engineering teams to continuously improve their processes and procedures to help secure Git Hub.

Communication and empathy is key in this role. Your collaboration with engineers is as important as the vulnerabilities and security risks you identify. In this role you’ll not only need to be creative and thorough in the attacks you perform, but also in helping drive the remediation strategies with teams across the company.
