POSITION SUMMARY:
Coalfire is on a mission to make the world a safer place by solving our clients’ toughest cybersecurity challenges.
As a leading cybersecurity solutions provider serving both private and public sector clients, we work at the cutting edge of technology—advising, assessing, automating, and guiding organizations through the ever-changing security landscape. Our professionals thrive on delivering unbiased assessments, expert guidance, and innovative strategies tailored to each client’s unique needs.
We are looking for a SIEM Platform Engineer to design, implement, operate, and continuously improve the security information and event management platforms that support Coalfire’s managed security and compliance services. This role owns the reliability and scalability of SIEM platform capabilities across cloud and high-compliance environments, including log collection, data onboarding, platform health, retention, performance, access, integrations, and operational automation.
The SIEM Platform Engineer partners closely with detection engineering, security operations, cloud engineering, compliance, and client stakeholders. The role ensures that SIEM platforms deliver high-quality, accessible, and appropriately governed security data while supporting continuous monitoring and regulatory requirements such as FedRAMP.
What You'll Do
- Design, implement, and maintain SIEM platform architectures across AWS, Azure, and GCP environments.
- Build and operate reliable log collection and ingestion pipelines, including forwarders, collectors, connectors, APIs, syslog, agents, and cloud-native services.
- Onboard, normalize, validate, and troubleshoot data sources from cloud platforms, operating systems, applications, network devices, identity systems, endpoint tools, and security controls.
- Establish and maintain platform standards for parsing, data models, field mappings, naming, tagging, retention, archival, access, and lifecycle management.
- Perform SIEM platform administration, including configuration, upgrades, patching, capacity planning, performance tuning, storage optimization, licensing, and availability monitoring.
- Develop and maintain infrastructure-as-code, automation, and deployment workflows using tools such as Terraform, Ansible, GitLab, GitHub, Python, or comparable technologies.
- Implement platform monitoring and health checks that identify ingestion gaps, pipeline failures, data quality issues, latency, resource constraints, and service degradation.
- Support the secure integration of SIEM platforms with endpoint, identity, vulnerability management, threat intelligence, network security, ticketing, and incident response systems.
- Provide dependable data and platform services to detection engineering and security operations teams; collaborate on use-case enablement without owning the full detection-development lifecycle.
- Support FedRAMP continuous monitoring and related compliance requirements by maintaining platform configurations, operational records, evidence, and repeatable procedures.
- Participate in platform changes, releases, migrations, and modernization efforts using documented change-management and testing practices.
- Follow and improve runbooks for platform incidents, data-source outages, ingestion failures, degraded performance, and other operational issues.
- Troubleshoot complex platform and integration issues, communicate impact clearly, and escalate appropriately when resolution requires additional expertise or authority.
- Create and maintain technical documentation, architecture diagrams, standard operating procedures, knowledge-base articles, and operational handoff materials.
- Participate in client meetings as a technical resource, explaining platform capabilities, requirements, constraints, risks, and remediation plans.
- Contribute to platform roadmaps, operational metrics, service improvements, and the development of reusable patterns across client environments.

- Experience diagnosing data quality, ingestion, pipeline, performance, availability, access, and integration problems.
- Experience working under strict regulatory or industry frameworks while maintaining practical, reliable, and supportable platform operations.
- Demonstrable client-facing experience in a consulting, managed-services, or professional-services capacity is preferred.
- Hands-on systems engineering and architecture experience, including requirements definition, architecture development, systems integration, testing, and operational support.
- Cloud experience in architecture, design, implementation, operations, and automation within AWS, Azure, or GCP.
- Practical administration and troubleshooting experience with one or more SIEM platforms, such as Splunk, Microsoft Sentinel, Elastic, or Sumo Logic.
- Experience designing or operating log collection, ingestion, parsing, normalization, enrichment, and retention workflows.
- Working knowledge of cloud-native logging and security services, operating systems, networking, identity, APIs, and enterprise security tools.
- Experience with automation and infrastructure-as-code practices using tools such as Terraform, Ansible, GitLab, GitHub, Python, or similar technologies.
- Understanding of platform reliability concepts, including monitoring, alerting, capacity planning, performance management, availability, backup, recovery, and disaster recovery.
- Ability to work effectively in Agile environments with cross-functional technical teams.
- Excellent communication, organizational, documentation, and problem-solving skills, with the ability to explain complex technical information clearly.
- Demonstrated ability to work independently and collaboratively while maintaining a professional attitude and demeanor.
- Critical-thinking skills to balance security, compliance, reliability, cost, and mission requirements.
- Ability to adapt quickly and operate effectively in fast-paced, dynamic environments.
- One SIEM or security operations certification, such as Splunk Enterprise Certified Admin, Sumo Logic Administration, or Microsoft Security Operations Analyst Associate.
