Desired Competencies (Technical/Behavioral Competency)

Must-Have** (Ideally should not be more than 3-5)

• GCP Services: BigQuery, Cloud Storage, Dataproc, Cloud Composer (managed Airflow) or self-managed Airflow.

• Airflow: Strong experience in DAG creation, operators/hooks, scheduling, backfilling, retry strategies, and CI/CD for DAG deployments. • Programming: Proficiency in Postgres Programming including Tables , Triggers, Views, Stored procedures, Python and Pyspark (PySpark, Airflow DAGs), SQL (advanced BigQuery SQL).

• Data Modeling: Dimensional modeling (Star/Snowflake), data vault basics, and schema design for analytics.

• Performance Tuning: BigQuery partitioning/clustering, predicate pushdown, job stats review, Dataproc executor tuning.

• Version Control & CI/CD: Git, branching strategies, pipelines for deploying Airflow DAGs and config.

• Operational Excellence: Monitoring with Stackdriver/Cloud Logging, debugging pipeline failures, and root-cause analysis.

• involves end-to-end ownership of data ingestion, transformation, orchestration, and performance tuning for batch and near real-time workflows.

Good-to-Have

• Streaming: Pub/Sub, Dataflow (Apache Beam) for near real-time pipelines.

• Orchestration Patterns: Event-driven pipelines, dependency management, and cross-environment promotion.

• Data Governance: Catalog/lineage tools (e.g., Data Catalog), PII handling, row-level security, column-level encryption.

• Containers & Infra: Docker, Terraform for IaC on GCP; Kubernetes concepts.

• BI Integration: Experience integrating with Looker, Tableau, or Power BI.

• Certifications: Google Professional Data Engineer / Cloud Architect.

Responsibility of / Expectations from the Role

1 Data Pipeline Development: Build robust ETL/ELT pipelines using Apache Airflow (DAG creation, scheduling, monitoring) to orchestrate data workflows across GCP services.

2 Data Warehousing: Design and optimize BigQuery schemas, partitioning/clustering strategies, materialized views, and query performance tuning.

3 Data Processing: Implement scalable data processing using Dataproc (Spark/Hive), including job configuration, optimization, and cost control.

4 Data Ingestion & Storage: Manage ingestion from diverse sources (APIs, files, streaming) and design storage strategies using Cloud Storage (lifecycle policies, tiers, security).

5 Quality & Observability: Implement data validation (e.g., Great Expectations or custom checks), logging/alerting, and SLA monitoring for pipelines.

6 Security & Governance: Apply IAM, service accounts, VPC SC, CMEK, and access policies across GCP resources; ensure compliance with data governance standards.

7 Cost & Performance: Optimize queries, cluster usage, and storage to balance cost/performance; leverage reservation/flex slots and job-level optimizations.

8 Collaboration: Work closely with analytics, product, and business teams to translate requirements into scalable data solutions; create documentation and handover materials.
