Vulnerability Researcher Assessments & Exercises

As an Vulnerability Researcher - Assessments & Exercises at JPMorgan Chase in the Cybersecurity Technology & Controls line of business you will contribute significantly to enhancing the firms cybersecurity or resiliency posture by using industry-standard assessment methodologies and techniques to proactively identify risks and vulnerabilities in people processes and technology. Design and deploy risk-driven tests and simulations (or manage a highly-skilled team that does) and inform analysis to clearly outline this role you will evaluate preventative controls incident response processes and detection capabilities and advise cross-functional teams on security strategy and risk management.

We are seeking a dedicated vulnerability researcher to engage in advanced vulnerability analysis and research addressing the complex demands of our this role you will work closely with fellow researchers and defense teams to identify vulnerabilities and develop cutting-edge solutions. The ideal candidate will be self-motivated possess extensive technical curiosity and have a strong background in reverse engineering. You will thrive in a collaborative environment working on challenging targets to enhance our security posture.
