Role Overview

We are looking for a Identity Security Analyst who will focus on investigating and resolving customer-reported security bugs. In this role, you’ll sit at the intersection of security research, product engineering, and customer success: you’ll reproduce issues, analyze impact and root cause, coordinate fixes with R&D, and communicate findings back to customers in a clear, actionable way.

This is a hands-on, technical position ideal for someone who enjoys debugging, incident-style investigations, and direct customer impact.

Key Responsibilities

Bug Triage & Investigation

Review and prioritize customer-reported security bugs (vulnerabilities, false positives, detection gaps, performance/coverage issues).

Reproduce issues in lab environments using customer-provided data, logs, and configurations.

Validate whether a bug is product defect, configuration issue, environmental limitation, or expected behavior.

Security Analysis

Analyze suspected vulnerabilities, misconfigurations, or detection gaps to determine impact, severity, and likelihood.

Correlate product behavior with attack techniques (e.g., MITRE ATT&CK, AD / identity attacks, NTLM relay, Kerberos abuse).

Perform log and event analysis (Windows Security / Sysmon / AD / LDAP / application logs) to understand bug context and side effects.

Resolution & Fix Coordination

Work closely with R&D / engineering teams to:

Provide clear reproduction steps, data, and technical context.

Propose mitigations and contribute to detection or logic fixes.

Verify hotfixes and releases against customer scenarios.

Track bugs through their full lifecycle to ensure timely resolution and high SLA adherence.

Customer Communication

Collaborate with Support, Customer Success, and SEs to:

Explain root cause and resolution in customer-friendly language.

Provide interim workarounds or configuration guidance when needed.

Contribute to knowledge base articles, runbooks, and best-practice guides.

Quality & Continuous Improvement

Identify recurring patterns in customer bugs and propose long-term product or process improvements.

Help refine internal monitoring, alerting, and testing for security-sensitive components.

Contribute to test cases and validation criteria for new features from a security QA perspective.

Required Qualifications

2–4+ years in a technical security or support role, such as:

Security Analyst / SOC Analyst

Security Engineer

Technical Support Engineer in a security or infrastructure product

Scripting and automation skills in PowerShell to speed up investigation and test setup.

Solid understanding of:

Identity and access concepts (Active Directory, authentication, privileges, groups)

Basic networking and protocols (TCP/IP, DNS, HTTP/S, SMB, LDAP/LDAPS)

Hands-on experience with:

Debugging and reproducing complex customer issues in lab environments

Strong analytical and problem-solving skills; able to systematically break down ambiguous issues.

Excellent written and verbal communication skills in English; able to explain complex technical findings to both technical and non-technical audiences.

Preferred Qualifications

Experience with enterprise security products, especially in one or more of:

Identity security / AD security

EDR/XDR, SIEM, or network security tools

Operating systems (Windows Server/AD)

Familiarity with MITRE ATT&CK and common attack patterns against AD and identity.

Familiarity with Azure DevOps

Experience working with bug trackers / case management tools.

Prior experience in a customer-facing role (support, consulting, PS) is a strong plus.

Hands-on experience with:

Log analysis (e.g., Windows Event Logs, Sysmon, SIEM)

What We Offer

Opportunity to work closely with security researchers and product engineers on real-world attacks and defenses.

Direct impact on customer satisfaction and product quality through high-value bug resolution.

A collaborative environment that values learning, knowledge sharing, and continuous improvement.
