Coordinate and develop hardware/software BOMs, manage vendor relations and purchase orders, track inventory and capital receipt, and lead rollout of network hardware to remote sites. Provide advanced router/switch configuration and system administration (Cisco required), ensure high-availability network designs, and produce clear technical documentation and status communications.

Design and implement anti-cheat systems across Windows and Linux, reverse engineer cheats, debug x86-64 binaries, collaborate with game teams and data analysts, and advance platform security and protection techniques.

Design, build, and improve anti-cheat backend services and game code for Fortnite. Debug and write C++ client and Go backend code, identify vulnerabilities, implement secure solutions, and assist in diagnosing live issues to ensure resilient, secure multiplayer operations.

Lead and perform red-team and penetration testing engagements across network, application, wireless, data center and cloud environments. Conduct complex security assessments, analyze findings, present remediation recommendations, implement solutions, and transfer knowledge to client staff. Partner with senior engineers and apply multi-discipline expertise to solve real-world security challenges.

Design and implement advanced cybersecurity solutions for DOE/NNSA programs. Perform security engineering, assessments, risk analysis, and compliance activities; develop software and technical solutions; support multi-lab teams; deliver cybersecurity training; and manage stakeholder priorities while using tools like Splunk, RSA, Tenable Nessus, and SELinux.

Own and harden cloud and device security for a wearable robotics fleet: design PKI and device identity, secure boot and OTA pipelines, harden GCP infrastructure, build security tooling and CI/CD signing, partner with firmware teams, and support compliance readiness for regulated market entry.

Support design, implementation, testing, and maintenance of cybersecurity controls for embedded Linux systems, network infrastructure, and communication equipment on autonomous maritime platforms. Develop security documentation, implement authentication/encryption/access controls, configure firewalls/VPNs/SSH/certificates, and participate in lab testing and field demonstrations to ensure compliance with industry and government cybersecurity standards.

Support RMF compliance and authorization activities for DoD systems: develop and maintain System Security Plans, POA&Ms, perform vulnerability scanning and remediation, implement STIG/SRG requirements, use tools like ACAS/SCAP/eMASS/VRAM, patch and image assets, and support configuration management and audits to obtain/maintain ATO/IATT/AO.
