We're looking for a Principal Data Platform Engineer to 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. This is a senior individual contributor role: you collaborate closely with the data domain, product, engineering and business stakeholders to understand the core use cases we need to support, and you translate that understanding into the architecture that delivers them. You 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. You design, you build where it matters, you operate, and you keep the standards you set — bringing rigour to architectural decisions by framing options, weighing trade-offs, and producing the documents that make the choices legible to leadership.
If you’re ready to own a critical domain end-to-end in a high-growth, global business - we’d love to hear from you.
