Principal Customer Data Platform Engineer

Airalo is seeking a Principal Customer Data Platform Engineer to own the customer data domain end-to-end. The successful candidate will collaborate with cross-functional teams to solve complex problems and influence how millions of travellers stay connected. The role requires a senior individual contributor with experience owning customer-data or data-platform architecture in a product-led organisation operating at meaningful scale.

Requirements

• Customer data architecture — from collection across web and app, through ingestion and modelling, into the activation surfaces where the business acts on it.
• Identity resolution: how users, devices, accounts, and sessions are stitched together across web and app, how that resolution is exposed to downstream consumers, and how it runs in production.
• Event schema architecture, versioning, and enforcement mechanisms — contracts, validation, schema registry, CI checks — that turn agreed event definitions into reliable, governed data.
• Consent architecture end-to-end: how consent is captured, propagated, stored, honoured at activation, and audited across regions and across the full chain from event collection to MarTech, so compliance is enforced architecturally rather than per-implementation.
• Establishing quality, lineage, and observability across customer-data flows so issues are detected upstream — not by analysts noticing broken numbers.
• Being the technical interface between Data and the functions that depend on customer data: Product Analytics owns what is tracked and why; you own how the platform captures, validates, routes, and governs it.
• Architecture and operation of warehouse-to-tool data flows: reverse ETL, audience activation, and the contracts that govern data leaving the warehouse.
• Data interface between experimentation platforms and the warehouse so assignments, exposures, variant metadata, and feature flag state land cleanly and reproducibly.
• Leading the customer-data architecture decisions ahead of us.
• Holding the architectural view of how the warehouse, collection layer, identity resolution, activation tools, and MarTech surfaces fit together as one coherent system.

Benefits

• Generous PTO
• Wellness and learning allowances
• Annual Airalo Away retreat
