The Senior Cyber Security Engineer will bridge the gap between "Compliance" and "Engineering." You will not just audit the system, you will help build it securely and own the cybersecurity workstream end-to-end. This role is responsible for achieving Authority to Operate (ATO) under DoD Risk Management Framework (RMF) standards among other federal certifications while embedding security automation directly into our CI/CD pipelines, and reporting program status and risk directly to LEXSO leadership. You will work side-by-side with backend and frontend engineers to harden the microservices architecture against evolving threats, and you will independently identify security gaps, drive architectural design decisions and shepherd remediation to completion..

The modern threat landscape poses complex challenges. In isolation, individual threats can be managed. However, when coordinated, complexity scales dramatically. Modern security requires detection across all threat types simultaneously. No single sensor or security solution can solve this problem.
LEXSO™ transforms the operational friction of sensor saturation into a unified, intelligent security system. As an AI-native, MOSA-compliant architecture, LEXSO™ fuses disparate sensor data directly at the edge. As a result, LEXSO™ detects, classifies and mitigates threats in sub-second timelines, maintaining a resilient operating picture even when the network is compromised.
