📋 Description

• Own the customer data domain end-to-end — the flows, the tracking and event architecture, the contracts, the identity logic, the consent logic, the activation paths, and the integrations that hold it all together. • Collaborate closely with the data domain, product, engineering and business stakeholders to understand the core use cases we need to support, and translate that understanding into the architecture that delivers them. • Set technical direction across functions, hold the line on architectural decisions that span them, and lead the choices about how tracking, collection, identity, governance, and activation evolve as Airalo scales. • Design, build where it matters, operate, and keep the standards you set — bringing rigour to architectural decisions by framing options, weighing trade-offs, and producing documents that make the choices legible to leadership.

🎯 Requirements

• Several years of experience owning customer-data or data-platform architecture in a product-led organisation operating at meaningful scale — including responsibility for the architectural decisions, not just the implementation. • Hands-on experience with first-party data architecture: capture, routing, identity resolution, and the architectural trade-offs across collection paradigms and across the real-time / batch boundary. • Deep technical fluency across the modern data stack: cloud warehouse (BigQuery, Snowflake or equivalent), dbt, reverse ETL (Hightouch or equivalent), event collection (client and server-side), and at least one major activation platform. • Strong working knowledge of the customer data platform ecosystem — packaged, composable, and warehouse-native patterns — and clear views on where each fits. • Hands-on experience with identity resolution in production — deterministic, probabilistic, or both — not only at the conceptual level. • Deep familiarity with consent architecture in practice: how consent signals propagate across server-side capture, Consent Mode, conversion APIs, and reverse ETL, and how to make compliance enforceable at the platform layer rather than per-implementation. • Working knowledge of experimentation platforms and what good experimentation data looks like end-to-end. • A track record of leading architecture decisions across functions — framing options, running evaluations, producing decision records, and bringing stakeholders to alignment. • Experience working alongside Engineering teams as a technical peer — setting specs they implement, reviewing their work, and being trusted to do so. • Strong written communication. Architecture decisions in this role land as documents, ADRs, and specs that other people act on. • A proactive, self-starter mindset. You thrive in ambiguity, work autonomously, and are energised by building in fast-paced, high-growth environments.
