Job description

The Azure Data Solutions Architect leads the design and implementation of enterprise-scale data solutions using Azure Data Factory, Azure Databricks, and Azure Synapse Analytics. This role provides architectural leadership, ensuring solutions are robust, scalable, and aligned with business strategy and industry best practices. The architect drives innovation, enforces governance, and mentors teams to deliver high-quality, future-ready data platforms that support organizational transformation.

Key Responsibilities

• Design and implement scalable data architectures using Azure services
• Build and optimize ETL/ELT pipelines using Azure Databricks and Apache Spark
• Architect data lake and data warehouse solutions using Azure Data Lake and Azure Synapse Analytics
• Ensure data security, governance, and compliance standards
• Collaborate with stakeholders to understand business requirements and translate them into technical solutions
• Optimize performance and cost efficiency of data workloads
• Mentor and guide data engineers and development teams
• Integrate advanced analytics, AI, and ML solutions when required

Skill Requirements

• Strong experience with Azure Databricks and Spark (PySpark/Scala)
• Hands-on experience with Azure services (ADF, ADLS, Synapse, Event Hub)
• Expertise in big data architecture and distributed systems
• Strong knowledge of SQL, Python, and data engineering concepts
• Experience with data modeling techniques (star schema, dimensional modeling)
• Understanding of real-time streaming (Kafka/Event Hub)
• Knowledge of DevOps and CI/CD practices

Strong Development Area:

Data Engineering Foundations
Batch vs streaming; lakehouse concepts; medallion (Bronze/Silver/Gold); file formats (Parquet/Delta/CSV/JSON/Avro); partitioning & clustering; schema evolution; data governance basics; DevOps/CI-CD for data.

SQL
Joins, subqueries, CTEs, window functions, set operations; aggregation & rollups; MERGE/UPSERT; analytic functions; performance (indexes, partition pruning, statistics); data validation scenarios (dedupe, top-N, SCD keys).

Apache Spark (Core)
Spark architecture (driver/executors), DAG, stages/tasks; RDD vs DataFrame/Dataset; wide vs narrow transformations; shuffle mechanics; caching/persistence; partitioning; broadcast joins; skew handling; checkpointing; job tuning.

PySpark
DataFrame API, Spark SQL; UDF vs pandas UDF; windowing; incremental loads; structured streaming (triggers, watermarks); handling semi-structured data; optimizing with predicates, pushdown, join strategies; error handling; unit testing (pytest + chispa).

Databricks Platform
Workspace basics; clusters (Single Node/All-Purpose/Jobs), cluster policies; DBR/LTS; notebooks & Repos; Jobs & Workflows; Delta Lake & Delta Live Tables; Unity Catalog (catalog/schema/table, permissions, lineage); MLflow basics; secret scopes; DBFS; REST APIs; Databricks Connect.

Delta Lake / Lakehouse Patterns
ACID transactions; schema enforcement/evolution; time travel; OPTIMIZE/ZORDER; VACUUM; CDC patterns (MERGE INTO, change data feed); streaming vs batch Delta; expectations/constraints; table maintenance strategies.

Orchestration & Scheduling
Databricks Workflows; Azure Data Factory/Synapse pipelines; triggers; parameter passing; fail/retry; alerts; integration with AutoSys/Control-M/Jenkins/GitHub Actions; event-driven patterns.

Python (Core for Data)
Core syntax; typing & data structures; file I/O; logging; virtual environments; packaging; testing (pytest); common data libs (pandas, pyarrow); error handling; performance considerations (vectorization, generators).

Data Quality & Testing
Great Expectations/dbx expectations or custom checks; unit/integration tests; reconciliation (row/amount); anomaly detection; contract testing for schemas; data observability (metrics, SLAs, freshness).

Security & Governance
Unity Catalog permissions, row/column-level security; secrets management (Key Vault/Secret scopes); PII handling; audit logs; token management; compliance basics.

Cost & Performance Optimization
Cluster sizing, autoscaling; DBU awareness; spot/preemptible instances; storage formats; caching; efficient joins; job scheduling; monitoring with metrics & Ganglia/Spark UI; cost tagging and chargeback.

Analytical Skills & Problem Solving
