About the Role
As a Senior Data Engineer specializing in Azure Big Data and AI Solutions (SAL2), you will:
- Lead AI & Data Engineering Innovations: Lead the design, implementation, and deployment of large-scale big data architectures, analytical frameworks, and self-service ETL platforms on the Azure ecosystem.
- Strategic Cloud Data Migration: Drive complex data migration strategies from legacy environments and on-premises clusters into modern cloud-native solutions, ensuring minimal disruption and maximum architectural integrity.
- Advance Generative AI & ML Systems: Incorporate machine learning models and foundational Generative AI components—including RAG frameworks and Large Language Models (LLMs)—into production-grade data pipelines.
- Optimize Production Pipelines: Architect, optimize, and maintain automated end-to-end data pipelines using Azure Data Factory (ADF) and Azure Databricks to process distributed datasets with low latency and high availability.
- Promote Data-Driven Decision-Making: Conduct deeply detailed source data analysis, profiling, and schema mapping across large-scale enterprise data warehouses to maximize data quality and business insight.
- Foster DevOps Excellence: Embed standard DevOps practices and CI/CD automated deployment paradigms into data processing solutions, ensuring reliable and maintainable code delivery.
Key Responsibilities
- Develop, optimize, and scale automated data ingestion pipelines using Azure Data Factory (ADF) and Azure Databricks in batch mode.
- Design and maintain custom self-service analytics platforms and modular ETL frameworks using Python and PySpark.
- Perform exhaustive source data analysis, data mapping, and granular profiling to enforce structure on unorganized or multi-source datasets.
- Build, integrate, and operationalize machine learning and GenAI applications utilizing Azure Machine Learning, RAG strategies, and LLM orchestration tools.
- Deploy, monitor, and configure helper cloud web services and infrastructure nodes including Azure WebApps, Key Vaults, Function Apps, and Logic Apps.
- Proactively tune the performance of complex SQL queries, Synapse Data Warehouses, and Spark computation engines to minimize compute costs and execution times.
- Collaborate with engineering and product stakeholders to rapidly adapt to new data technologies and resolve intricate platform bottlenecks.
Your Skills & Experience:
- BS/MS in Computer Science, Mathematics, Engineering, Statistics, or another quantitative/computational field. Advanced degrees preferred.
- Expert-level proficiency in programming paradigms with Python and distributed cluster computing via PySpark and Apache Spark.
- Deep, hands-on architectural experience with Azure cloud services, specifically Azure Data Factory (ADF), Azure Databricks, and Azure Synapse / SQL Server.
- Demonstrated experience designing and maintaining large-scale enterprise Data Warehouses, covering data integration and schema design mapping.
- Solid command of SQL scripting, window functions, query execution planning, and the optimization of complex dataset manipulations.
- Familiarity with DevOps implementations, including CI/CD automated release management pipelines mapped for data applications.
- Practical understanding of building and deploying machine learning models or integrating GenAI capabilities (RAG, LLM tooling).
- Experience configuring helper microservices including Azure Function Apps, Logic Apps, and credential isolation protocols through Azure Key Vault.
Set Yourself Apart With:
- Microsoft Certified: Azure Data Engineer Associate, Azure AI Engineer Associate, or Databricks Certified Professional credentials.
- Proven track record migrating multi-terabyte on-premises clusters (Hadoop/legacy appliances) into cloud infrastructure ecosystems.
- Advanced experience productionizing scalable vector indexing, specialized embeddings, or high-performance inference endpoints for RAG systems.
- Strong leadership footprint or mentorship history driving technical agility and modern coding patterns within data-centric teams.
PERSONAL ATTRIBUTES
- Strong written, verbal, and interpersonal communication skills.
- Proven problem-solving skills with a high degree of adaptability to learn new and emerging data technologies.
- Collaborative, self-starter mindset requiring minimal supervision while executing complex tasks under high agility.
- Ability to effectively balance, prioritize, and manage multiple projects without sacrificing delivery quality.
EXPERIENCE
5.5 to 8 years of total experience with a focus on cloud big data and analytical model engineering.
