Trusted by organisations including Temenos, LTIMindtree, and Infosys Finacle, we are scaling globally from our Barcelona headquarters and building the next generation of AI-native trust infrastructure.
We are looking for a Principal Architect to lead the design of Ditto’s Intelligence & Shared Signals platform — the continuous trust layer powering adaptive identity assurance, behavioural intelligence, federated risk decisioning, and AI-agent trust.

You’ll work across Ditto Verify, Authenticate, and Protect, combining identity, authentication, behavioural telemetry, device intelligence, and cryptographic assurance into a unified trust platform.
We’re looking for someone with:
- 10+ years in security, identity, fraud, risk, or trust architecture
- 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.
Recruitment Process:
- Introductory conversation with Talent
