Senior Security Analyst

Full Job Description

Lead deep-dive investigations into the most complex and high-severity security incidents, including root cause analysis, blast radius assessment, threat actor attribution, and impact/scope determination. Drive cross-team response for nation-state, supply chain (npm, GitHub, OpenVSX), and identity-based compromises - partnering with MSTIC, OpsHub, Detection Engineering, Evictions, and Service teams to contain and remediate at scale. Translate investigation findings into durable improvements - new detections, platform fixes, playbooks, and process changes - so the same class of attack does not succeed twice. Raise the bar on investigation quality, contributing to documented standards, peer reviews, and measurable rigor across incidents, hunts, and forensics. Leverage AI and Copilot technologies to accelerate triage, evidence collection, and analysis, helping the team stay ahead of attackers operating at machine speed. Mentor and uplevel peers in advanced investigation techniques, threat actor tradecraft, and reverse engineering, building a strong culture of investigative excellence.

These requirements include, but are not limited to the following specialized security screenings: Bachelor's degree in Computer Science, Information Security, a related technical field, AND 4+ years of experience in cybersecurity, incident response, coordination and presentation with executive level professionals, threat hunting, or security investigations OR equivalent experience (6+ years of hands-on security investigation/forensic experience in lieu of degree). 3+ years of experience conducting security investigations in large-scale cloud or enterprise environments (Azure, AWS, GCP, or M365). Demonstrated experience with log analysis and query languages (KQL/Kusto, SQL, or equivalent) across SIEM, identity, endpoint, or cloud telemetry. Working knowledge of modern attacker tradecraft, the MITRE ATT&CK framework, and common cloud/identity attack paths (e.g., token theft, OAuth abuse, supply chain compromise). Experience investigating nation-state or financially motivated threat actors and producing attribution-quality analysis. Hands-on experience with supply chain compromise investigations (npm, GitHub Actions, OpenVSX, signing/artifact abuse) or identity-plane incidents (Entra ID/AAD, ESTS, federation). Experience building or consuming AI/Copilot-assisted investigation tooling, automation, or notebooks to scale analyst workflows.
