Senior Staff Incident Response Engineer at Sofi · LumiJobs

Responsibilities

As a Senior Staff Incident Response Engineer on the Cyber Defense team, you will serve as the principal technical authority and subject matter expert for incident response within SoFi’s Security Operations Center (SOC). You will lead investigations and mitigation actions against threats targeting crypto and digital asset platforms, while securing our core enterprise and cloud infrastructure (AWS/GCP, applications, identity, and endpoints).
This position sits within Incident Response (IR) in SoFi’s Cyber Defense organization. In partnership with our Cyber Incident Commander, you will handle high-severity incidents, architect containment workflows, and lead technical forensics across distributed systems. Pairing specialized digital asset threat knowledge with an engineering skill set, you will perform forensic triage, build automated investigation tools, and translate findings into hardened detection mechanisms and playbooks across the enterprise.
Serve as the SOC’s subject matter expert for digital asset and cryptocurrency security, investigating and neutralizing threats directed at digital asset platforms and services.
Apply blockchain investigation methods, forensic telemetry, and analytical tooling to execute scoping, containment, and recovery operations.
Investigate and resolve security alerts and incidents across digital asset, cloud, application, identity, and endpoint environments, driving issues from initial triage to root cause and remediation.
Perform forensic triage and deep data study, including cloud and application log review, endpoint artifact inspection, evidence preservation, and timeline reconstruction.
Write clean, maintainable code (Python, Go, or SQL) to test large datasets, correlate telemetry across disparate log sources, and automate evidence collection and enrichment workflows.
Partner cross-functionally with Detection Engineering, Application Security, and Core Infrastructure teams to construct and tune threat detections, address logging gaps, and track systemic remediations to completion.
Partner with SOC analysts and the Cyber Incident Commander on incident operations, providing technical direction on complex investigations and high-severity incidents.
Develop and maintain crypto-specific and cloud-specific incident response runbooks and response procedures.
Document investigations thoroughly and deliver technical findings and post-incident reviews to technical and executive stakeholders.
Lead technical simulations and tabletop exercises encompassing digital asset and smart contract failure modes.
