As a Senior Cybersecurity Engineer in the Security Validation team, you will be a key member of our Red Team operations, leading efforts to emulate real-world threat scenarios and validate the effectiveness of enterprise defenses across our expansive healthcare environment. This role requires advanced offensive security capabilities, deep knowledge of adversary tactics, and the ability to communicate findings clearly to both technical and executive stakeholders. You will design and execute advanced threat simulations against our infrastructure—cloud, clinical systems, APIs, IoT medical devices, and enterprise platforms—helping CHS proactively identify and mitigate systemic weaknesses. You will also work with internal teams and third parties to provide feedback on the relevance of vulnerabilities to CHS systems, ensuring alignment between threat findings and risk remediation efforts. Your work will directly impact patient safety, data integrity, and regulatory compliance across a network of hospitals and clinics.
