Sr. Cyber Security Engineer

Job description

Axos Business Center, Corp About This Job The Senior Security Engineer is a key technical leader within Axos Bank’s Security Engineering organization and plays a central role in transforming our traditional Security Operations Center into an AI driven, investigation centric threat response function. This lrole is not a traditional SOC analyst position—it is an engineering forward role focused on deep incident investigation, advanced threat detection engineering, proactive threat hunting, and enhancing the AI SOC platform so it can autonomously perform higher quality investigations at scale. The ideal candidate is highly technical, curious, and hands on—comfortable analyzing complex attack patterns, engineering detections, and building automation that amplifies the speed and precision of Axos’s AI enabled SOC. Key Responsibilities Cybersecurity Incident Investigation Lead complex security incident investigations across cloud, identity, endpoint, application, and network layers. Perform root‑cause analysis, kill‑chain reconstruction, and evidence preservation with engineering‑grade depth. Convert investigation findings directly into new detections, automation playbooks, and AI features to reduce recurrence and detection gaps. Participate in a mandatory on‑call rotation, serving as a senior escalation point for complex security incidents—ensuring rapid, high‑quality investigative response and feeding lessons learned back into detections, automations, and the AI SOC platform. Threat Detection Engineering Design, build, and tune high‑fidelity detection logic across Splunk, SOAR, cloud platforms, and other security telemetry systems. Establish repeatable processes for hypothesis‑driven detection creation, simulation, validation, and tuning. Improve detection precision by reducing false positives and strengthening behavioral and contextual analytics. Proactive Threat Hunting Conduct proactive, intelligence‑driven hunts across large datasets using advanced analytics, anomaly detection, and adversary‑emulation techniques. Identify unknown threats, emerging attacker behaviors, and gaps in telemetry or tooling. Translate hunting insights into durable detections, AI models, automated enrichment, and new investigation workflows. AI SOC Platform Enhancement Improve the AI SOC platform’s ability to perform autonomous or semi‑autonomous investigations by contributing high‑value signals, features, and decision logic. Work closely with AI and Security Engineering leadership to integrate hunting patterns, investigation heuristics, and detection insights into AI pipelines. Build feedback loops that allow AI models to learn from analyst investigations and improve over time. Automation & SOAR Engineering Create high‑reliability automation workflows that handle triage, enrichment, correlation, and containment actions. Collaborate with Detection Engineering and Splunk/automation teams to integrate new data sources, threat‑intelligence feeds, and enrichment pipelines. Collaboration & Engineering Excellence Work closely with SecOps, Cloud, AppSec, Detection Engineering, and AI Engineering teams to strengthen detection coverage and reduce operational friction. Produce high‑quality documentation, playbooks, knowledge articles, and engineering runbooks. Mentor SOC analysts, junior engineers, and cross‑team partners to uplift investigation quality and detection maturity. Required Qualifications 5+ years of experience in cybersecurity (incident response, threat detection, security engineering, or threat hunting). Strong technical expertise in cloud security, identity security, endpoint telemetry, network analysis, or application security. Proven ability to perform deep‑dive incident investigations involving cloud IAM, lateral movement, privilege escalation, API abuse, malware, or application‑layer threats. Hands‑on experience with SIEMs (Splunk preferred), EDR tools, SOAR platforms, and automation frameworks. Ability to write and tune detection rules, correlation logic, saved searches, and behavioral analytics. Strong scripting ability (Python preferred) and familiarity with data analysis techniques. Willingness and ability to participate in a mandatory on‑call rotation and act as a senior escalation point during high‑severity incidents. Preferred Qualifications Experience partnering with AI/ML engineering teams or contributing to AI‑assisted security tooling. Background in threat intelligence, malware analysis, or offensive security (red team, adversary emulation). Knowledge of cloud‑native detection patterns (AWS, Azure), identity‑based attacks, and API security. Certifications such as GCIH, GCDA, GDAT, GCTI, GCFA, or equivalent are a plus.
