The role partners closely with Cybersecurity, Security Engineering, Risk/Compliance, and Operations, and includes mentoring junior SIEM engineers.

Key Responsibilities

• Architect & own Splunk SIEM (Enterprise/ES or equivalent): indexing strategy, data models, CIM alignment, RBAC, scaling/HA, and performance tuning.
• Design & implement data onboarding pipelines: forwarders/heavy forwarders, syslog/HTTP events, parsing/normalization (props.conf, transforms.conf, sourcetypes), data quality.
• Develop content: correlation searches, risk-based alerts, dashboards, reports, KPIs, and scheduled searches to prioritize threats and reduce noise.
• Engineer use cases mapped to frameworks (e.g., MITRE ATT&CK); create playbooks/runbooks for incident investigation and response.
• Integrate SIEM with endpoint, network, cloud, identity, and ticketing tools; coordinate with vendors as needed.
• Collaborate with Cyber/SecEng on complex investigations; perform root-cause analysis and recommend remediation.
• Lead SIEM upgrades, enhancements, and integrations; define standards, patterns, and guardrails for sustainable operations.
• Mentor & review: guide junior engineers; review designs and changes from less-experienced staff.
• Champion best practices and adhere to Client SDLC, change management, and security policies in a regulated environment.

Required Qualifications

• Combined 8+ years of higher education and/or professional experience in systems design/management/architecture.
• Splunk expertise (5+ years) in engineering/administration, including:
• SIEM design and operations (indexer/search head clustering, data retention, search performance).
• Data modeling & parsing (CIM, sourcetypes, field extractions, regex, props/transforms).
• Content development (correlation searches, dashboards, alerts, reports, KV store).
• Strong understanding of the infrastructure lifecycle, ITSM practices, and systems design.
• Experience collaborating with stakeholders across cyber, operations, compliance, and risk; clear written/verbal communication.
• Ability to lead initiatives independently, mentor others, and deliver results in a fast-paced environment.

Preferred Qualifications

• Bachelors in Computer Science, Computer Engineering, or related field.
• 8+ years in technical engineering involving infrastructure design, data management/interchange, and large-scale systems.
• Splunk certifications (Certified Architect, Enterprise Security Admin), plus security certs (e.g., CISSP, GIAC).
• Banking/financial-services experience; familiarity with regulatory drivers (e.g., FFIEC/GLBA/SOX).
• Advanced troubleshooting of ingestion failures, parsing issues, and search performance; scripting (e.g., Python, Bash) for automation.
• Effective facilitation and influencing skills; process-oriented, logical thinker; adaptable and quick learner.
