We are seeking a mid to senior Splunk Data Administrator to own and continuously improve Splunk data onboarding, normalization, and quality across a complex hybrid Splunk environment (on‐prem and cloud).
The ideal candidate is hands‐on with CIM alignment, data source onboarding, field extractions (regex/props/transforms/ingest actions), TA deployment, and end‐to‐end operational management of Splunk data pipelines.
You will act as the key point of contact for ensuring log sources are onboarded correctly, parsed and normalized consistently, and made usable for security/IT operations, dashboards, correlation searches, and reporting.
Key Responsibilities
Data Onboarding & Lifecycle Management
Lead onboarding of new log sources end‐to‐end: requirements gathering, source validation, parsing strategy, TA selection/deployment, CIM alignment, testing, and release.
Partner with Security/IT teams to translate use‐cases into data requirements, ensuring sources deliver the right fidelity, timeliness, and coverage.
Manage onboarding at scale using best practices for source types, metadata strategy, index & sourcetype governance, and naming conventions.
Define and enforce data quality standards (field completeness, timestamps, event consistency, parsing accuracy, duplication control).
Normalize data to Splunk Common Information Model (CIM) with strong understanding of data models (e.g., Authentication, Network Traffic, Endpoint, Change, etc.).
Ensure fields are aligned to CIM requirements to support Splunk Enterprise Security (ES) and other CIM‐based content.




Validate normalization using SPL and develop reusable onboarding checklists.
Design and implement robust field extractions using:regex and structured parsing (KV_MODE, JSON, XML)
sourcetype / timestamp / line breaking configuration
Implement enrichment and routing using event breaking, host/source normalization, lookups, and tagging.
Install, configure, and maintain Splunk Add‐ons (TAs) and apps across:Indexers / Search Heads / SHC
Deployment Server / Cluster Manager (where applicable)
Maintain version compatibility and upgrade strategies for:Splunk Enterprise / Splunk Cloud
Add‐ons, apps, and content packs
Package and deploy TAs using deployment pipelines and change management controls.
Ensure fields are aligned to CIM requirements
Hybrid Splunk Architecture Operations
Operate and support Splunk in complex environments:On‐prem Indexer Cluster, Search Head Cluster, Forwarder tiers
Splunk Cloud integrations where applicable (e.g., Heavy Forwarder, VPN, PrivateLink, data forwarding patterns)
Configure and troubleshoot data ingestion pipelines:Syslog (UDP/TCP), API‐based collection, HEC, file monitors, Windows Event Logs, cloud sources




Ensure performance and reliability across the pipeline, including indexing throughput, parsing overhead, and search impact.
Monitoring, Troubleshooting & Governance
Monitor ingestion health and pipeline performance:
Maintain governance for indexes, sourcetypes, retention, RBAC and data access boundaries (as required).
Contribute to operational runbooks, SOPs, and documentation; drive continuous improvement in onboarding and normalization standards.
Required Skills & Experience (Mid–Senior)
5–10 years experience with Splunk administration and data onboarding (or equivalent depth).
Strong practical knowledge of:
Field extraction (regex, JSON/KV extraction), and troubleshooting parsing issues
props.conf / transforms.conf, sourcetypes, timestamps, line‐breaking
TA installation/configuration and deployment patterns across Splunk tiers
Experience with complex Splunk architectures:
Indexer clusters, SH/SHC, forwarder management, deployment server
Hybrid patterns (on‐prem + cloud), connectivity, and ingestion strategies
Comfortable writing and validating SPL for data quality and CIM compliance.
Cloud: AWS/Azure/GCP logging patterns (nice‐to‐have)
Preferred / Nice-to-Have
Experience with Splunk Enterprise Security (ES) and ES add‐ons / CIM compliance expectations.
Knowledge of Splunk Ingest Actions / Edge Processor (or up-to-date ingestion tools, where applicable).
Familiarity with:
ITSI / Observability (bonus)
Splunk Core Certified Power User / Admin
