What you’ll do :

• Build and evolve backend services, APIs and platform tooling used by data and engineering teams.
• Design robust integration and ingestion services connecting applications, systems and storage.
• Develop performant data models and scalable, resilient storage solutions.
• Improve data quality, observability, lineage and platform reliability.

• A pragmatic, analytical approach to complex engineering challenges.
• Strong communication skills and the ability to influence technical and business stakeholders.
• Fluency in English (C1 or better); Spanish is advantageous.
