Platform Security Engineer

TEKsystems•Rockville, MO

1d•$70 - $80•Hybrid

About The Position

Our Security Operations Center is evolving from foundational capabilities into a mature, comprehensive security operations program. We need an experienced SOC engineer who has been part of a top-tier SOC and can provide technical vision and leadership to guide our detection engineering and automation efforts. This role focuses on building robust detection capabilities, automating security responses, and creating the frameworks that enable our SOC analysts to effectively identify and respond to threats. You will work closely with our threat intelligence and hunting teams to translate security research into actionable detections and automated responses.

Requirements

SOC Experience: 5+ years in a Security Operations Center environment with exposure to mature SOC operations and best practices
SIEM Expertise: Hands-on experience with Splunk Enterprise Security or comparable enterprise SIEM platforms (building correlation searches, alerts, dashboards, and ES-specific frameworks)
Detection Engineering: Proven experience developing security detections, use cases, and alert tuning methodologies
MITRE ATT&CK Framework: Practical application of MITRE ATT&CK for detection coverage mapping and gap analysis
Security Automation: Experience building automated response workflows and playbooks (SOAR platforms preferred)
Scripting: Strong proficiency in Python, PowerShell, or Bash for automation and integration development
Cloud Security: Understanding of cloud security monitoring and detection across AWS, GCP, and Azure environments
Analytical Mindset: Ability to identify gaps, define clear vision for improvement, and guide teams toward maturity

Nice To Haves

Splunk SOAR (Phantom) hands-on experience
Splunk UEBA or behavioral analytics platform experience
Risk-Based Alerting (RBA) implementation experience
Threat hunting background with detection engineering application
Infrastructure automation and CI/CD pipeline knowledge
Experience mentoring or leading detection engineering teams
Relevant certifications (GIAC, CISSP, or similar)
Experience setting up internal SOC "Guidance" knows the what potential pitfalls to be aware how things should work.
Running into issue where their teams don’t know how to define good soc
step in and help, been part of soc, well oiled machine, experience with what does/doesn’t work
Senior level- not lead, Senior engineer hands on with detections
most of it built out, just need extra help
expand detections, detection engineering, vulnerabilities, scripting if needed
consulting in a way, help guiding, wouldn’t own whole process, have analyst team, need an engineer to point out mistakes and roadblocks
Splunk enterprise security for detections, Splunk soar for automation, SPLUNK UEBA
could translate through other SIEM tools, could be taught Splunk but it’s being used currently so they’ll have a leg up if they have that already
analysts will do the actual work, design and improve whole enterprise security
goal is to reduce work load for analysts, automate and take work off their hands
working with threat team, if new vulnerability helps with detections
