Senior Detection & Platform Engineer – SOC / Security Automation

Job Title: Senior Detection & Platform Engineer
Location: Dallas, TX (Hybrid)
Employment Type: Long-Term Contract

Job Summary

We are seeking an experienced Detection & Platform Engineer with strong hands-on experience in SOC engineering, detection engineering, security automation, and security platform integration.

This is not a traditional SOC Analyst role. The ideal candidate will have a strong software-engineering mindset and experience building scalable solutions that improve the effectiveness and efficiency of security operations.

The engineer will be responsible for developing and maintaining Detection-as-Code (DaC) pipelines, SIEM/SOAR integrations, security automation, detection content, API integrations, and AI-assisted SOC capabilities. The role will work closely with SOC Analysts, Threat Hunters, Detection Engineers, Threat Intelligence teams, Infrastructure Engineers, and Security Leadership.

Key Responsibilities

Detection-as-Code & Detection Engineering

• Design, build, and maintain Detection-as-Code (DaC) pipelines.
• Develop, test, validate, version, and deploy security detections through CI/CD pipelines.
• Establish detection development standards, automated testing, code review, and deployment processes.
• Develop and tune high-fidelity detections across:
  • Endpoint/EDR telemetry
  • Cloud security telemetry
  • Network telemetry
  • Email security telemetry
  • DLP telemetry
• Reduce false positives while improving detection coverage and alert fidelity.
• Maintain detection logic, metadata, documentation, ownership, and lifecycle management.
• Translate threat intelligence and SOC analyst requirements into production-ready detection content.
• Apply detection engineering methodologies aligned with MITRE ATT&CK and enterprise security requirements.

SIEM & SOAR Engineering

• Engineer, administer, optimize, and support SIEM/SOAR platforms.
• Develop and maintain SIEM queries, correlation rules, alerts, dashboards, and detection content.
• Build and maintain SOAR playbooks for investigation, enrichment, containment, and response.
• Develop integrations between SIEM, SOAR, EDR, identity, cloud, email, ticketing, and threat intelligence platforms.
• Troubleshoot security data ingestion, platform integrations, automation failures, and detection deployment issues.
• Improve the reliability, scalability, and performance of security operations platforms.

Security Automation & API Integration

• Identify repetitive SOC processes and develop automation to reduce manual analyst effort.
• Develop reusable Python scripts, APIs, workflows, and automation components.
• Integrate security platforms and services using REST APIs, JSON, and webhooks.
• Automate alert enrichment using threat intelligence, asset information, identity data, and other contextual sources.
• Improve investigation efficiency, response times, consistency, and overall SOC productivity.

AI-Assisted SOC Engineering

• Identify opportunities to leverage Generative AI, LLMs, and AI agents within security operations.
• Support AI-driven alert investigation, triage, enrichment, summarization, and detection development.
• Integrate AI capabilities with existing SIEM, SOAR, and SOC workflows.
• Establish appropriate validation, governance, and controls for AI-assisted security outcomes.

Platform Engineering & Operations

• Monitor and optimize the performance, reliability, scalability, and availability of security platforms.
• Troubleshoot production issues and participate in incident resolution.
• Support platform upgrades, integrations, configuration changes, and operational improvements.
• Develop and maintain technical documentation, architecture diagrams, runbooks, and operational procedures.
• Collaborate with SOC, Threat Hunting, Threat Intelligence, Detection Engineering, Infrastructure, and Security Leadership teams.

Required Qualifications

• 5+ years of experience in cybersecurity, SOC engineering, detection engineering, security automation, or related fields.
• Hands-on experience with Detection-as-Code or automated security detection deployment.
• Strong experience with SIEM and SOAR platforms and SOC operational workflows.
• Experience developing and tuning security detections across endpoint, cloud, network, email, or DLP telemetry.
• Strong experience with Python or similar scripting/programming languages.
• Hands-on experience with security automation, SOAR playbooks, REST APIs, and platform integrations.
• Experience with Git, CI/CD, version control, automated testing, and deployment pipelines.
• Strong understanding of security events, logs, telemetry, detection logic, alerting, and incident response.
• Experience integrating multiple security platforms through REST APIs and webhooks.
• Strong troubleshooting, analytical, and problem-solving skills.
• Ability to work independently in a fast-paced engineering environment.

Preferred Qualifications

• Experience with Sigma, YARA, or other detection/content-as-code frameworks.
• Experience with Splunk, Microsoft Sentinel, IBM QRadar, Elastic, or similar SIEM platforms.
• Experience with Cortex XSOAR, Splunk SOAR, Microsoft Sentinel/Logic Apps, or similar SOAR platforms.
• Experience with CrowdStrike Falcon, Microsoft Defender, SentinelOne, or similar EDR platforms.
• Experience with security telemetry from AWS, Azure, and/or Google Cloud Platform.
• Experience with GitHub, GitLab, Azure DevOps, or similar DevOps platforms.
• Experience with threat intelligence platforms and automated enrichment.
• Experience with Generative AI, LLMs, AI agents, or AI-assisted SOC operations.
• Strong understanding of MITRE ATT&CK and modern detection engineering methodologies.
• Experience working in a large-scale enterprise SOC environment.
