Job Description

Blackstone’s front-line cyber defense team is seeking an associate incident responder to detect, investigate, and respond to information security incidents across multiple domains.

Responsibilities

Manage an incident queue from intake through investigation, containment, and closure across email, endpoint, identity, network, and cloud
Handle Tier 1 escalations by taking ownership of more complex investigations and bringing in additional responders as scope expands
Investigate incidents in the firm’s SIEM, writing and refining searches to pivot across endpoint, authentication, email, network, and cloud telemetry
Perform endpoint investigation, host containment, and live response in the EDR platform, including process lineage, persistence review, and artifact collection
Investigate email threats end to end (phishing, business email compromise, malicious attachments and links) using header and message trace analysis to identify targeted users and drive mailbox remediation
Investigate cloud and identity compromise, including credential misuse, role and privilege abuse, session hijacking, and multi-factor bypass
Investigate third-party and SaaS provider compromises by coordinating with the provider’s incident response team to confirm containment and determine what Blackstone data was affected
Independently scope exposure by hunting provider indicators across endpoint, email, network, and cloud telemetry; coordinate findings and remediation with legal and compliance, vendor risk, and business owners
Serve as a core incident response team member by scoping intrusions, driving containment and eradication, briefing stakeholders, and escalating using the firm’s severity model
Author and tune detections based on investigation findings, validating logic against historical and live data, moving detections through review into production, and confirming real-world firing without unacceptable noise
Collaborate with agentic AI investigation tooling for first-pass triage and enrichment, evaluate outputs, escalate inaccuracies, and feed corrections back to improve coverage
Help expand detection and response coverage for the firm’s increasing use of AI across a fast-moving attack surface
Turn investigation findings into durable coverage by reducing false positives and building automation to remove repetitive triage, enrichment, and response steps
Mentor Tier 1 analysts on investigation technique through case reviews and hands-on coaching
Document investigations and incidents with audit-ready evidence handling and chain of custody; communicate clearly to technical teams and senior stakeholders
Contribute to threat hunts and purple team exercises using red team activity and threat intelligence to identify gaps
Participate in incident response and SOC on-call rotation (occasional, roughly quarterly) to respond to escalated security incidents

Requirements

2+ years of hands-on experience in security operations, incident response, or a comparable technical security role
Proven ability to run security investigations end to end from alert through root cause and containment in a SOC or IR environment
Hands-on SIEM experience, including writing and troubleshooting queries; experience with a major enterprise SIEM and native query language (Splunk/SPL, Microsoft Sentinel/KQL, or Elastic)
Hands-on EDR experience for endpoint investigation and containment; experience with a leading EDR platform (CrowdStrike, SentinelOne, or Microsoft Defender for Endpoint)
Working knowledge of cloud and identity investigation, including cloud audit logging, IAM, SSO, and identity providers such as Okta or Microsoft Entra ID
Practical understanding of attacker behavior across the intrusion lifecycle, including phishing and business email compromise, credential theft, privilege escalation, lateral movement, persistence, and exfiltration
Familiarity with security tools involved in investigations: email security, endpoint protection, proxies and firewalls, DLP, and vulnerability data
Working knowledge of MITRE ATT&CK and experience mapping observed activity to techniques
Experience scripting in Python and/or PowerShell for enrichment, parsing, and automation of repetitive analysis
Demonstrated hands-on use of AI tooling in real work, including the ability to explain projects in detail and exercise judgment about when outputs cannot be trusted
Clear technical writing to explain incident impact to engineers and non-technical stakeholders
Ability to self-organize, prioritize during time pressure, and remain accurate during live incidents
