JOB DESCRIPTION

Job: OT Security Consultant (Splunk)
Location: Houston, TX - onsite
Duration: 12 Months
Rate: $80 to $85 per hour

ROLE AND RESPONSIBILITIES

Operational Technology (OT) Cybersecurity Consultant to lead Splunk detection engineering for a customer Security Operations Center (SOC). This hands-on role requires production SOC experience, an understanding of how OT environments differ from traditional IT, and advanced Splunk expertise. The consultant will evaluate current use cases, improve correlation and alert quality, develop new detection content, coach analysts, and create clear documentation that enables the team to sustain the work independently.

Responsibilities:

- Catalogue and assess existing Splunk correlation searches, dashboards, and use cases against an agreed baseline, identifying coverage gaps and noisy rules.
- Co-author a prioritized roadmap with the Nozomi lead during the initial phase of the engagement.
- Design, test, and refine Search Processing Language (SPL) correlation searches, notable event logic, and detection content tailored to OT data sources.
- Recommend and implement approved adjustments to thresholds and suppression logic to reduce false positives, and track the impact of each change.
- Review OT log sources, parsing, normalization, field extraction, and enrichment so detections are based on reliable data.
- Partner with the Nozomi lead to normalize, enrich, and correlate Nozomi alerts and asset data in Splunk.
- Coach SOC analysts using real investigations and teach effective pivots across OT and IT data.
- Create a runbook and tuning rationale for each new or materially changed use case, and teach analysts to build and tune searches independently.
- Provide monthly reporting on changes, rationale, alert volume, false positive rate, and coverage improvement.
- Coordinate with customer teams, implementation partners, change control, and related Splunk workstreams so improvements are delivered smoothly.
