• Establish and maintain engineering best practices, secure coding standards, and operational security procedures
• Guide junior engineers in understanding complex adversary behaviors and translating them into technical implementations

Attack Path Development & Implementation

• Design and implement advanced attack paths that emulate sophisticated adversary campaigns across multiple domains
• Create reusable, production-grade components for complex attack techniques including credential harvesting, lateral movement, and defense evasion
• Develop custom tooling and automation frameworks that operate at machine speed for large-scale adversary emulation

Data Engineering & Intelligence Integration

• Lead the design of ETL pipelines for processing threat intelligence, security logs, and operational data at scale
• Architect standardized schemas for cyber operations datasets that support graph-based analysis and AI/ML workflows
• Implement advanced data enrichment pipelines that integrate diverse threat intelligence sources
• Design efficient storage and retrieval systems for large-scale security-relevant data

Operational Collaboration

• Work closely with government customers and operational teams to understand mission requirements and capability gaps
• Translate operational feedback into technical requirements and development priorities
• Lead technical demonstrations showcasing offensive cyber capabilities to stakeholders
• Provide subject matter expertise for customer engagements and strategic planning sessions
