We are proud of: The work we do and the innovation we drive Our values of share, care a nd dare A workplace culture that fosters creativity, diversity and autonomy Our borderless, global framework, which enables seamless collaboration The role We are looking for an experienced Senior Data Engineer to design, build, and optimize modern, cloud-based data platforms that power analytics, AI, and data products. Beyond technical delivery, we want someone genuinely curious about the business problems behind the data, who applies common sense, detailed analysis, and experience-based recommendations to help shape business requirements, not just implement them as given. You will work on scalable batch, streaming, and near-real-time pipelines, delivering high-quality curated datasets with robust governance, security, and observability. You will also support AI and GenAI systems, enabling pipelines for machine learning, causal modeling, and LLM-powered applications such as RAG and agent-based systems, and collaborate closely with data scientists, ML engineers, and platform teams. Platforms Our work is centered on AWS with Databricks, with growing demand on GCP, including cloud migration programs. Azure/Fabric experience is also valued. We are looking for engineers with deep expertise in one cloud who are T-shaped: comfortable working across clouds and keen to broaden their platform experience. You’ll be staffed on projects that fit your strongest platform, with opportunities to expand. Responsibilities Build & Data Platform Engineering Design and implement scalable data platforms and pipelines, primarily on AWS and Databricks, and on GCP or Azure/Fabric where projects require. Develop reliable batch, streaming, and near-real-time pipelines using Spark and Delta Lake. Build ingestion, transformation, and curation workflows for structured and unstructured data. Implement lakehouse patterns and medallion layering (bronze, silver, gold), ensuring reusable, scalable systems aligned with enterprise needs. Contribute to cloud-to-cloud migrations, including re-platforming pipelines and data models. Enable AI, GenAI & Data Products Deliver model-ready, production-grade datasets for analytics, ML, causal modeling, and optimization. Build data pipelines for GenAI use cases (LLMs, RAG, vector-based data flows) and agent-based architectures. Leverage Databricks MLflow and Unity Catalog, or equivalent tooling on other platforms. Data Modeling, Orchestration & Automation Design logical and physical data models for analytical and operational use cases. Orchestrate workflows with Databricks Workflows, Airflow, dbt, or equivalents (e.g., Azure Data Factory, Cloud Composer), with a focus on automation, reliability, and maintainability. Architecture, Governance & Observability Apply event-driven and streaming architecture patterns. Ensure data governance, lineage, quality, and access control (RBAC/ABAC) using Unity Catalog, AWS Lake Formation, or equivalents (Microsoft Purview, GCP Dataplex). Establish observability: data freshness, pipeline reliability, and SLA adherence. Data Serving, Integration & Optimization Enable serving layers (APIs, feature inputs, analytical endpoints) for downstream ML and AI platforms. Continuously optimize pipelines and infrastructure for performance, scalability, and cost. Requirements Discovery & Business Partnership Ask the right questions to understand not just…
