Summary:
BlueVoyant is seeking an experienced and proficient Security Content Engineer to join our Threat Fusion Cell (TFC). As a trusted and established member of our team, you will operate with a high degree of autonomy to own and enhance the detection and automation content that protects our global clients. You are a dependable, hands-on expert in the full content lifecycle, capable of managing complex logic, optimizing for signal quality, and serving as a reliable technical resource for the team. This role is ideal for a seasoned professional who consistently delivers high-quality work with minimal supervision.

Key Responsibilities:

Own and Enhance Detection Content: Autonomously develop, test, and maintain high-fidelity detection logic in KQL for the Microsoft Sentinel environment. You will own a portfolio of content, ensuring its long-term effectiveness and performance.

Conduct Advanced Tuning & Optimization: Perform independent and complex global tuning to improve SOC efficiency and outcomes. Proactively identify and resolve sources of alert fatigue and false positives across our customer base.

Lead Threat-Informed Research: Independently research emerging threats, attack vectors, and high-risk vulnerabilities to design and develop proactive detection strategies, not just reactive rules.

Develop Scalable Automation: Design and build automation content for key security workflows, including product onboarding and incident enrichment, with a focus on reusability and efficiency.

Serve as a Technical Resource: Act as a knowledgeable point of contact for clients on complex tuning requests and provide clear guidance on detection logic. Collaborate with integration teams to define requirements for optimizing log ingestion.

Improve Team Frameworks: Contribute to the evolution of security policies and automation frameworks by providing expert feedback and identifying areas for improvement based on hands-on experience.

Required Qualifications & Experience:

5-8 years of direct experience in Detection Engineering, Security Operations, or a similar role with a heavy focus on content creation.

Deep, hands-on expertise with the Microsoft security stack, including Microsoft Sentinel, Microsoft 365 Defender, and Logic Apps.

High proficiency in Kusto Query Language (KQL), with proven experience writing complex, optimized queries for detection and hunting.

Strong, demonstrated experience automating security workflows using SOAR platforms, APIs, or scripting languages (Python, PowerShell).

Proven ability to operate with a high degree of autonomy, managing competing priorities and complex projects with minimal supervision.

In-depth knowledge of attacker TTPs, the MITRE ATT&CK framework, and modern blue team operations.

Excellent analytical and problem-solving skills, with experience in deep log analysis and digital forensics.

Strong collaboration and communication skills, with the ability to clearly explain complex technical concepts.

Preferred Qualifications & Experience:

Experience in a large-scale Managed Detection and Response (MDR) environment.

Familiarity with CI/CD pipelines and version control (Git) for managing "detections-as-code."

Advanced industry certifications such as GCIH, GDAT, GCFA, or OSCP.
