Senior Security Operations Engineer

About the role

Location: Remote (US-based) About Dispel: Dispel is the fastest-growing cybersecurity company recognized in the 2025 Cybersecurity Excellence Awards. We deliver zero trust secure remote access and real-time data streaming for operational technology (OT) and industrial control systems (ICS). Our patented Moving Target Defense technology — referenced in NIST 800-172 — protects critical infrastructure for utilities serving 54 million+ people, manufacturers producing over 50% of US baby formula, and major defense contracts including a $950M IDIQ with the US Air Force. Why This Role Exists: Dispel is pursuing FedRAMP High authorization while simultaneously operating a commercial security program. We have a functioning SOC built on Google SecOps (Chronicle) and SentinelOne, but we need a senior IC who can take it from "stood up" to "operationally mature." You'll own the log ingestion pipeline end-to-end and drive material expansion of coverage across federal and commercial environments, including AWS, Azure, and Entra ID. This person will be the day-to-day technical owner of SOC operations, responsible for closing coverage gaps, building detections, maturing incident response, and providing senior technical direction to the existing SOC analyst. This is a hands-on-keyboard role with leadership expectations — you will not formally manage people, but you will set priorities, review deliverables, and drive execution across the SOC function. Requirements Key Responsibilities: SIEM/SOAR Operations (Google SecOps) Own the log ingestion pipeline end-to-end: identify gaps, build feeds, validate parsing, maintain coverage dashboards Close the federal logging gap and stand up commercial logging across AWS, Azure, Entra ID, and SaaS Activate and configure SecOps SOAR capabilities including Domain-Wide Delegation, marketplace integrations, and bidirectional response actions Build and maintain SOAR playbooks for major incident types such as phishing, malware, account compromise, lateral movement, and cloud-specific threats Develop and maintain operational dashboards for SOC metrics, alert volumes, MTTA/MTTR, and coverage status Manage Google SecOps RBAC Detection Engineering Build and deploy production detection rules mapped to MITRE ATT&CK within the first year Develop custom parsers for AWS-native security services including GuardDuty, Security Hub, Inspector, WAF, CloudTrail, and VPC Flow Logs Establish a detection lifecycle including proposal, testing, deployment, tuning, and retirement Conduct quarterly detection quality reviews to measure false positive rates, coverage gaps, and rule health Develop alert threshold optimization to reduce noise and analyst fatigue Endpoint Detection and Response (SentinelOne) Drive SentinelOne deployment across Azure VMs in commercial environments and all federal endpoints Configure and operationalize Cloud Funnel for log export into Google SecOps Build correlation rules between EDR alerts and SIEM detections Manage SentinelOne RBAC groups and policy configuration Coordinate with IT on agent deployment, health monitoring, and version management Incident Response Serve as senior escalation point for SOC incidents, ensuring investigations are thorough and reports include root cause, remediation actions, credential rotation plans, and follow-up timelines Improve MTTA and MTTR through process optimization, better tooling, and analyst development Lead quarterly tabletop exercises and after-action reviews Maintain and improve incident response runbooks for all major incident categories Integrate incident response workflows with Jira Service Management for tracking and escalation Vulnerability Management Operationalize monthly scanning cadence across all environments using tools such as Nessus, AWS Inspector, and Azure Defender Define and enforce remediation SLAs by severity: Critical within 72 hours, High within 7 days, Medium within 30 days Build consolidated vulnerability dashboards in Google SecOps Track SLA compliance and report metrics to the CISO Coordinate remediation with engineering and infrastructure teams MSSP Oversight Serve as primary technical interface with MSSP partner for 24/7 SOC coverage Define and hold the MSSP accountable to SLAs, alert quality, and escalation procedures Review MSSP deliverables such as dashboards, reports, and playbooks for quality and completeness Manage the transition from the previous MSSP and ensure no coverage gaps SOC Team Technical Leadership Provide day-to-day technical direction to SOC analysts by setting priorities, assigning tasks, and reviewing work products Ensure incident response reports, playbooks, and dashboards meet quality standards before delivery to leadership or external stakeholders Drive OKR execution for SOC-related objectives including logging coverage, detection counts, incident response metrics, and vulnerability SLA compliance Identify skill gaps and development opportunities for junior analysts Establish and enforce SOC processes that are documented, repeatable, and auditable Required Qualifications: 6+ years of experience in security operations, detection engineering, or SIEM/SOAR engineering Hands-on experience with Google SecOps (Chronicle) or equivalent enterprise SIEM such as Splunk, Sentinel, or QRadar, with Chronicle strongly preferred Production experience with SentinelOne, CrowdStrike, or a comparable EDR platform Deep knowledge of AWS security services including GuardDuty, Security Hub, Inspector, CloudTrail, WAF, and Config Experience building detection rules mapped to the MITRE ATT&CK framework SOAR playbook development and automation experience Demonstrated ability to lead without formal authority by setting direction for peers or junior analysts Strong incident response skills with experience writing complete reports for executive and external audiences Understanding of NIST 800-53 controls, particularly Audit, System Integrity, and Incident Response families Excellent written communication sk
