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.
Recruitment Process
Introductory conversation with Talent
CTO & CPO conversations
Collaborative 90-minute architecture working session
Final meeting with Ditto leadership
If you want to build category-defining infrastructure shaping the future of digital trust, we’d love to hear from you.
