Deep experience with real-time event-driven and streaming systems
Strong data-engineering and feature-engineering expertise
Experience building adaptive trust, behavioural intelligence, or signal-fusion platforms
Practical experience integrating AI/LLM systems into production environments
Excellent written and verbal communication skills in English

Nice to Have
