Vigilance MDR Security Analyst

What are we looking for?

SentinelOne is looking for mid-level MDR Analysts who are inquisitive, calm under pressure, and passionate about applying their cybersecurity knowledge and skills to protect our global clients. You’ll join a supportive, globally distributed security team focused on detecting, analyzing, and responding to threats in real-time. Whether it’s tuning detections, investigating alerts, or helping our customers understand risk, you’ll be hands-on in shaping how we defend against modern threats

This isn’t a gatekeeping, ego-filled team—we believe security is a team sport. You’ll bring your expertise and grow it here, working alongside thoughtful, inclusive teammates who support one another.

What will you do?

• Monitor and triage security threats, respond to incidents, and guide clients through remediation and mitigation efforts.
• Collaborate with internal MDR and MDR-adjacent teams on various projects, tasks, and initiatives to improve our ability to detect and respond to threat actors.
• Query and analyze log data using the SentinelOne Singularity Platform and become an expert in using our bespoke DFIR tools to identify and contextualize threats across EDR, cloud, and network sources.
• Tune and provide feedback on detection rules to reduce noise and improve signal quality.
• Write clear, detailed incident reports that communicate findings to both technical and non-technical audiences.
• Collaborate with detection engineers, threat intel, and client teams to improve the overall quality of the MDR service.
• Function as a force multiplier by training and mentoring fellow analysts both in one-on-one and group settings.
• Contribute to process improvements and knowledge sharing to make the SOC better every day.

What experience or knowledge should you bring?

• 2–4 years of experience in a SOC, IR, MDR, or similar environment.
• A mindset that values learning, collaboration, and making things better.
• Experience with SIEM and EDR platforms.
• Comfort investigating alerts from tools like CrowdStrike, SentinelOne, Splunk, Rapid7, or Microsoft 365 Defender.
• Understanding of attacker tactics (MITRE ATT&CK, phishing, lateral movement, etc.) and how to spot them.
• Clear written and verbal communication—you can explain your thought process and back it up.
