The Senior Cloud Cybersecurity (CCS) Detection and Response Engineer will collaborate with Detection, Security, and Software Engineers to proactively defend Tanium Cloud's services. You will be an integral part of the Tanium Cloud security engineering processes, responsible for the design, implementation, and operation of preventative, detective, and responsive controls to identify, assess, and counter risks and threats before impacting Tanium Cloud.

• Build and operate Tanium Cloud's detection and response engineering in Azure, AWS, and Kubernetes for detections, analysis, and responses as automation as code using Dev Ops methodologies
• Continuously evaluate and enhance the design and effectiveness of Cloud and Kubernetes security measures and establish an ongoing program to advance security and close gaps in our defensive posture.
• Proactively characterize unauthorized activity and malicious behaviors in our cloud and container infrastructure and systems through code, testing, and automation
• Develop tailored detection policies, perform testing, and implement automation to observe, evaluate, enhance, and review security information using Sec Data Ops  and best practices.
• Proactively integrate the latest security threats, vulnerabilities, and industry trends to enhance security detection measures and generate intelligence driven hunts.
• Work together with the engineering, IT, and other security groups to create solutions that are expandable and adaptable to protect Tanium Cloud against threats ranging from low-level actors to national cyber‑threat agents.
• Build, cultivate, and maintain positive relationships with internal customers to identify and facilitate solutions to increase the impact of the team's work
• Be on periodic on‑call for triage of critical events from detections and systems

• Bachelor's degree or equivalent experience
• Cloud Security, IT Security, or related technical field preferred

• U.S. Candidates:
  In accordance with United States government customer requirements, applicants for this role must be a U.S. citizen, national, or resident pursuant to 8 U.S.C. 1101(a)(20) and 8 U.S.C. 1324b(a)(3)
