Senior Security Engineer- Security Operations

At GE Appliances, a Haier company, we come together to make “good things, for life.”  As the fastest-growing appliance company in the U.S., we’re powered by creators, thinkers and makers who believe that anything is possible and that there’s always a better way.  We believe in the power of our people and in giving them the freedom to explore, discover and build good things, together.  

The GE Appliances philosophy, backed by three simple commitments defines the way we work, invent, create, do business, and serve our communities: we come together, we always look for a better way, and we create possibilities. Interested in joining us on our journey? GE Appliances is seeking a Senior Security Engineer, Security Operations to serve as the senior technical lead for the company’s detection and response capability.

Day-to-day 24x7 monitoring, alert triage, and vulnerability operations are delivered by our managed security services provider (MSSP); this role is not a shift lead or people manager. Instead, it owns the engineering behind the SOC — the detection and response platforms, detection content, automation, and telemetry — and drives the execution and continuous enhancement of how threats are detected, investigated, and contained across enterprise IT, cloud, and manufacturing (OT) environments.

The engineer acts as the MSSP’s technical counterpart and the escalation point for complex incidents, and is accountable for measurable improvements in detection coverage, detection fidelity, and response speed.

Serve as the senior technical lead and subject-matter expert for security operations, owning the architecture, configuration, and operational health of the detection and response platforms and setting the technical standards the MSSP operates against.

Design, build, test, and maintain detection content — correlation rules, behavioral analytics, and IOC/BIOC rules — mapped to the MITRE ATT&CK framework, and manage the full detection lifecycle using detection-as-code practices (version control, testing, peer review, and documentation).Own telemetry coverage: identify visibility gaps and onboard, parse, and normalize log sources across endpoints, identity, Microsoft 365, cloud, network, email, DLP, and OT;

Serve as the Tier 3 escalation point and technical lead for complex or high-severity incidents escalated by the MSSP, performing hands-on investigation, endpoint and log analysis, scoping, and containment, and coordinating with the external incident response retainer when engaged.

Lead hypothesis-driven threat hunting informed by threat intelligence and threats targeting manufacturing, converting hunt findings into durable detections and hardening recommendations.
