Design, deploy, and operate network security infrastructure including firewalls, segmentation, and DMZ. Collaborate with Cybersecurity and Network teams to detect/mitigate threats, evaluate new platforms, improve observability through scripting, and support business workflows securely.

Deploy and document security controls at scale, run vulnerability management, support incident response, collaborate with IT/engineering to build technical and procedural solutions, and maintain operational playbooks for Windows-focused environments.

Lead migration and optimization of log ingestion and observability pipelines. Design, implement, and operate load-balanced, highly available Cribl/Splunk pipelines; onboard and tune security log sources; apply data reduction; collaborate with SOC/IR; monitor pipeline and SIEM health; document governance, retention, and cost-savings metrics.

Lead and perform application and network penetration tests, source code and cloud security reviews, and produce clear pentest reports. Research and develop pentesting tools/methods for blockchain and Web3, contribute to community content, and support client security engagements.

Design and deliver integrated access control, video surveillance, and visitor management systems for commercial and data center projects. Create layouts, schematics, and documentation using CAD/Revit, manage multiple projects, collaborate with clients and vendors, support business development, and stay current with industry technologies.

Lead application security for an AI-native enterprise coaching platform: review code and architecture, threat model, perform manual pentests, build security tooling, advise DevOps on infrastructure security, support incident response and SOC processes, and handle client-facing security needs.

Designs and audits secure network and cloud architectures, evaluates firewall changes, manages SSE/CASB tooling, governs SaaS security, and assesses AI-related security risks. Partners with engineering, legal, and compliance to implement controls, investigate incidents, and develop reusable security standards and documentation across enterprise systems.

Build, operate, and secure AWS cloud environments to meet FedRAMP and government security standards. Integrate security into CI/CD, IaC, and deployment workflows; support authorizations, audits, vulnerability management, system hardening, and compliance documentation.

The Principal Cloud IAM Engineer will lead the strategy and design for Workday's IAM program, ensuring security in a complex multi-account AWS environment and mentoring less experienced engineers.

The Software Engineer will design and develop full-stack applications to enhance application security, using modern development practices and leveraging AI tools.
