Who we are looking for 

We are looking for a Senior SIEM Data Engineer reporting directly to the Cyber Data Engineering Manager. You will lead the design, onboarding, transformation, validation, and operational support of cybersecurity telemetry and enterprise log data used for security monitoring, analytics, reporting, incident response, and cyber data science use cases. 

This role is focused on understanding diverse enterprise data sources, designing scalable security telemetry pipelines, improving log fidelity and data quality, and ensuring reliable delivery of high-value data into cyber data platforms such as Splunk, Databricks, and other SIEM or cyber analytics platforms. You will work closely with cybersecurity, infrastructure, cloud, application, and data engineering teams to ensure security telemetry is accurate, complete, searchable, governed, and fit for purpose. As a senior engineer, you will also help define onboarding standards, mentor engineers, drive operational maturity, support complex troubleshooting, and contribute to the evolution of enterprise cyber data engineering capabilities. 

Why This Role Is Important to Us 

The team you will be joining is part of Cyber Data & Analytics, a function that is vital to the company as it enables cybersecurity teams to make faster, data-driven decisions and strengthen the firm’s ability to detect, investigate, and respond to evolving cyber threats. 

High-quality cybersecurity data is foundational to effective threat detection, incident response, risk reporting, observability, automation, analytics, and compliance. This role helps ensure that enterprise security telemetry is properly onboarded, validated, enriched, routed, monitored, and continuously available to support critical cyber defense capabilities. 

What you will be responsible for 

As Senior SIEM Data Engineer you will: 

• Design, build, and maintain scalable SIEM and security telemetry pipelines across hybrid and multi-cloud environments. 

• Lead onboarding of security telemetry from applications, infrastructure, endpoints, identity platforms, network devices, cloud services, SaaS tools, databases, and security products. 

• Analyze source log formats and define onboarding requirements, expected fields, metadata, routing needs, retention considerations, and downstream SIEM/analytics use cases. 

• Build and optimize telemetry pipelines for parsing, filtering, masking, enrichment, normalization, event breaking, metadata tagging, and multi-destination routing. 

• Deliver reliable security telemetry to Splunk, Databricks, and other SIEM or cyber analytics platforms. 

• Design and support Databricks data engineering patterns across raw, enriched, curated, and analytics-ready data layers. 

• Validate data quality across cyber data platforms for freshness, completeness, correctness, availability, timestamp accuracy, schema consistency, source attribution, routing accuracy, and latency. 

• Establish SIEM onboarding standards for source classification, source types, index routing, taxonomy alignment, metadata tagging, schema expectations, CIM/ECS alignment, and data quality controls. 

• Optimize telemetry pipelines to reduce noise, control ingestion cost, improve performance, and preserve high-value security data for detection and investigation. 

• Lead troubleshooting of complex ingestion and data flow issues across sources, collectors, pipelines, SIEM platforms, Databricks tables, APIs, cloud storage, and streaming platforms. 

• Provide second-line-of-defense support, escalation, and root cause analysis for operational issues related to data engineering jobs, pipelines, ingestion failures, and issues leading to loss of data delivery to cyber data platforms. 

• Automate deployment, monitoring, alerting, validation, pipeline testing, repeatable onboarding, and operational support using CI/CD and infrastructure-as-code practices. 

• Partner with Detection Engineering, Security Operations, Cyber Data Science, Observability, Cloud, Infrastructure, Application, Governance, Risk, and Platform teams to ensure telemetry supports business and security use cases. 

• Create and maintain onboarding standards, data flow diagrams, field mappings, transformation logic, runbooks, troubleshooting procedures, operational handoffs, and engineering documentation. 

• Mentor engineers and promote best practices for security telemetry onboarding, data quality, automation, reliability, operational excellence, and secure engineering. 

What we value 

These skills will help you succeed in this role 

• Strong experience with SIEM data onboarding, security telemetry pipelines, log ingestion, routing, parsing, enrichment, validation, and troubleshooting. 

• Strong hands-on experience with Splunk or similar SIEM/log analytics platforms. 

• Hands-on experience with Cribl Stream or similar data pipeline technologies for routing, filtering, parsing, enrichment, transformation, event breaking, replay, and multi-destination delivery. 

• Ability to understand and onboard telemetry from diverse enterprise data sources across cloud, endpoint, identity, network, application, infrastructure, database, SaaS, and security platforms. 

• Working knowledge of Databricks or similar analytics/lakehouse platforms, including raw ingestion, enrichment, curated datasets, table design, partitioning, data quality checks, and analytics-ready outputs. 

• Strong understanding of data quality concepts, including log fidelity, freshness, completeness, correctness, availability, schema consistency, duplicate detection, routing validation, and ingestion latency. 

• Strong understanding of data engineering concepts such as data layers, schema design, metadata management, transformation, enrichment, deduplication, batch/streaming ingestion, and pipeline monitoring. 

• Practical knowledge of SIEM taxonomy, source classification, security use case mapping, CIM/ECS alignment, schema mapping, and enterprise log onboarding standards. 

• Strong understanding of DevOps, DataOps, DevSecOps, CI/CD, infrastructure-as-code, automation, and production support practices. 

• Strong troubleshooting, documentation, communication, stakeholder management, prioritization, mentoring, and end-to-end ownership skills.
