Document troubleshooting activity and customer interactions clearly and consistently.
Collaborate with other specialized support engineers and escalation specialists on complex technical problems.
Identify recurring issues and contribute to knowledge articles, troubleshooting guides, videos, and other reusable resources.
Provide structured feedback when product usability or supportability improvements could reduce customer effort.
Continuously expand your technical knowledge of SentinelOne products, operating systems, cybersecurity, and troubleshooting methodologies.

Ideal candidates will have:

Previous technical support or customer-facing technical experience on endpoint security or enterprise security products.
Working knowledge of Windows, macOS, and/or Linux, and understanding of networking and basic security concepts.
Customer focus, a desire to solve technical problems, the ability to manage multiple customer issues while maintaining quality and urgency, and comfort working in a fast-moving technical environment.
Proven analytical, troubleshooting, and problem-solving skills, and the ability to systematically investigate complex technical issues (including crash dumps) and clearly document findings.
Excellent written and verbal communication, collaboration skills, and willingness to learn from others.
Scripting experience with PowerShell, Python, Bash, or a similar tool is an advantage.
Experience troubleshooting endpoint or server environments is an advantage.
Familiarity with cloud platforms or SaaS technologies is an advantage.
Cybersecurity education, certifications, or professional experience is an advantage.
