The Role  

We are seeking a hands-on Senior Data Engineer to join our Data and Analytics Platform team, driving the strategy, design and implementation of our next-generation cloud-based Data Fabric and Data Mesh platform (Data Platform 2.0). This is a deeply technical role for a builder who enjoys writing high-quality code, designing scalable systems, and working directly with engineering teams to implement complex, real-time data solutions. You’ll be equally comfortable sketching out an event-driven architecture for a business unit, contributing code to shared data infrastructure, and guiding implementation across multiple domains. This role is pivotal to enabling teams to create scalable, data-driven products and underpinning our enterprise-wide data strategy. 

Our Vision  

We believe decentralized data is the future, with Data Platform 2.0 as the key to unlocking its potential. Our vision is a world where data is treated as a product, ownership is distributed to foster innovation, and domain-oriented, decentralized infrastructure drives agility and collaboration. While supporting challenging data sets, and, flexible scenarios required for Agentic AI, Sandbox environments and more 

The Data Platform 2.0 transforms data into a strategic asset. Through well-defined data domains and business ownership, we aim to: 

• Empower teams with self-serve data infrastructure
• Treat Data Domains as first-class products
• Shift responsibility to domain teams to foster accountability and innovation

By embracing platform thinking and adhering to the four pillars of Data Mesh: data ownership, data as a product, self-service infrastructure, and federated governance. We are enabling a seamless experience for creating, discovering, and utilizing trusted, connected, and real-time data. 

If you are passionate about shaping the future of data through cutting-edge architectures, fostering a culture of data stewardship, and enabling decentralized innovation, we’d love to hear from you!
