Data Developer

Data Platform Architecture & Development Own the design and evolution of the platform's end-to-end data architecture across Cosmos DB , Azure Data Explorer (ADX) , Azure SQL, and Fabric . Architect and optimize Cosmos DB for high-throughput IoT workloads: partition key strategy, indexing policy, schema design, TTL configuration, RU/s throughput tuning, and change feed utilization. Build and manage ADX clusters: ingestion pipelines (Event Hub ingestion, ingestion mappings, update policies), KQL query optimization, retention and caching policy tuning, and materialized views for analytics. Design and manage Azure SQL schemas, stored procedures, and ETL jobs supporting relational reporting and operational data needs. Architect data flow across the hot path (Event Hubs → real-time processing), warm path (Cosmos DB operational queries), and cold/analytics path (ADX long-term telemetry retention and aggregation). Build and maintain ingestion pipelines using Azure Functions , Event Hubs , and Service Bus . ETL / ELT & Data Transformation Design and implement high-throughput ingestion pipelines processing millions of IoT device events per day, including telemetry, alarms, lifecycle events, and geospatial data. Build transformation and enrichment logic in C#/.NET, Python, and/or pySpark integrated with Azure Functions and Event Hub triggered pipelines. Implement data quality, validation, deduplication, and anomaly detection within ingestion pipelines. Apply CI/CD practices for data pipeline deployment using GitHub Actions or Azure DevOps . Design and maintain ADX update policies and Cosmos DB change feed processors for downstream data propagation. Data Modeling & Storage Strategy Design scalable, queryable data models for time-series telemetry, alarm events, geospatial lookups (H3 hexagonal indexing), and fleet/asset metadata. Implement optimal partitioning strategies tailored to Cosmos DB (tenant + device key patterns) and ADX (ingestion time partitioning, row ordering policies). Model multi-tenant data isolation and access patterns in both Cosmos DB and Azure SQL. Manage data lifecycle policies across ADX (hot/cold cache tiers, retention) and Cosmos DB (TTL, archival strategy). Collaborate with backend engineering to define microservice data contracts and Cosmos DB document schemas that support both operational APIs and analytics queries. Cross-Functional Collaboration Partner with platform architects on the evolution of the next-generation telematics platform data architecture. Work closely with backend (JAVA) engineers to support ingestion patterns, event processing, and data contract design across microservices. Support product and business stakeholders with analytics queries, reporting, and ad hoc data investigation using ADX/KQL. Partner with project managers to deliver data milestones predictably and communicate risks early. Operations & Reliability Own reliability, observability, and SLA of all data pipelines across the production SaaS platform. Monitor, diagnose, and optimize costs across Cosmos DB (RU/s utilization), ADX (compute and storage tiers), Azure SQL, Event Hubs, and Azure Functions. Implement proper governance, RBAC, and data access controls consistent with multi-tenant SaaS
