Principal Architect - Intelligence & Shared Signals

Ready to help define the future of continuous trust?

Ditto is a fast-growing B2B SaaS company redefining how regulated industries establish digital trust. Our privacy-first identity platform, built on Zero-Knowledge Proof technology, powers secure and compliant customer interactions across banking, fintech, crypto, travel, and gaming.

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.

This is a rare opportunity to architect foundational platform technology at the intersection of identity, security, AI, behavioural intelligence, and post-quantum cryptography.

You will lead the architecture behind:

continuous trust decisioning

shared signals and federation (CAEP/RISC/SET)

streaming pipelines and feature stores

behavioural intelligence systems

Identity Assurance Graphs

AI-agent and workload identity evaluation

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.
