Enterprise Architect (Data/AI/Cloud) – Full Remote Portugal

ABOUT THE OPPORTUNITY This is a Principal-level architecture role with real organisational weight — not an advisory seat, not a governance committee. You'll define and own the end-to-end technical architecture across data, AI, and platform domains at a company operating at global scale. Your decisions will shape engineering strategy across multiple product teams, influence long-term infrastructure investments, and set the standards that hundreds of engineers build against. If you've earned your credibility in the trenches of software and data engineering and you're ready to operate at the intersection of technical vision and business strategy, this is the scope you've been waiting for. PROJECT & CONTEXT You'll work across a multi-squad, multi-domain engineering organisation, defining Architecture Decision Records, leading cross-functional technical forums, and translating business goals into coherent, long-term engineering roadmaps. The scope spans cloud-native infrastructure, data platform architecture, AI/ML system design, API governance, and security and compliance including GDPR. This is an environment where architectural coherence is treated as a product in itself — and where the person in this role has genuine influence over how it evolves.
