• 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

Experience with Kafka/Pulsar, CAEP, RISC, feature stores, OPA/Rego, Zero Trust, post-quantum cryptography, SIEM/XDR architectures, or mobile threat defence is highly valued. Spanish is a plus.
