Job Description

WHAT WE'RE LOOKING FOR:

CERTIFICATIONS:

Preferred SnowPro Core and/or SnowPro Advanced certifications. dbt Certification (Analytics Engineer) is a plus.

EXPERIENCE:

• 10–12 years of overall experience in IT, with a strong focus on data engineering and cloud data platforms.
• 6+ years of architecture or engineering experience in data modeling, building data pipelines, ELT/ETL frameworks, data products, and distributed data systems.
• 6+ years of experience within Data Warehousing: management (star schemas, snowflake schemas, dimensional modeling) within Snowflake.
• 4+ years of hands-on experience with dbt (data build tool) — building and maintaining modular transformation layers, testing frameworks, macros, and documentation (dbt docs/lineage).
• 3+ years of hands-on experience with Fivetran (or similar managed ELT/connector tools) for automated data ingestion from SaaS, ERP, and database sources.
• 3+ years of experience enabling or supporting BI/reporting layers using Power BI — including semantic modeling, DAX, and performance optimization of datasets feeding dashboards.
• Exposure to or working knowledge of Generative AI concepts and tools (LLM-based data documentation/cataloging, natural-language-to-SQL tools, AI-assisted data quality or anomaly detection, Copilot-style dev tooling) — hands-on production experience is a plus, not mandatory.

Nice to have:

• 5+ years of experience with Python for data engineering (scripting, automation, orchestration).
• Experience with PySpark for large-scale data processing.
• Experience processing semi-structured data (JSON, Parquet, Avro).
• Exposure to orchestration tools (Airflow, Dagster, or Snowflake Tasks/Streams).
• Familiarity with using LLMs/GenAI APIs (OpenAI, Azure OpenAI, AWS Bedrock) to accelerate data engineering workflows — e.g., auto-generating dbt documentation, AI-assisted SQL/data quality checks, or building lightweight natural-language query interfaces over Snowflake.
  

THOSE NECESSARY TO PERFORM THE JOB COMPETENTLY:

• Thorough knowledge of Snowflake architecture (virtual warehouses, micro-partitioning, clustering, cost/performance optimization).
• Strong hands-on experience building and maintaining dbt projects — models, tests, snapshots, incremental strategies, and CI/CD integration for dbt deployments.
• Strong hands-on experience configuring and managing Fivetran connectors, sync schedules, transformations, and troubleshooting ingestion failures.
• Expertise in designing data models (dimensional modeling, star/snowflake schemas) for both operational reporting and self-service analytics.
• Should have worked on preparation of Technical Specification documents and data pipeline design documentation.
• Working knowledge of SAP systems as a source system (SAP ECC/S4HANA extraction patterns), integrated via Fivetran or custom pipelines into Snowflake.
• Experience enabling Power BI consumption layers — building/optimizing Snowflake views or dbt marts specifically for BI performance.
• Very good analytical skills to independently analyze and resolve ELT, SQL, and pipeline issues.
• Ability to provide effort estimation for data engineering initiatives.
• Ability to engage directly with business stakeholders, gather requirements, and work independently to translate them into scalable pipeline/data model designs.
• Advanced knowledge of data warehousing concepts and schema design trade-offs.
• Curiosity and practical interest in applying GenAI/LLM capabilities to modernize data engineering workflows (e.g., automated documentation, natural-language interfaces, intelligent data quality monitoring).
• SAP functional knowledge is good to have.
  

PREFERRED QUALIFICATIONS:

Bachelor's degree in Engineering (Computer Science or other equivalent majors).

HOW YOU WILL THRIVE AND CREATE AN IMPACT:

• Collaborate with the Analytics and BI teams to prototype and prove the viability of new data solutions, including GenAI-assisted approaches where applicable.
• Own the end-to-end data pipeline lifecycle: ingestion (Fivetran) → transformation (dbt) → storage/modeling (Snowflake) → consumption (Power BI).
• Lead development and execution of data engineering initiatives across specific projects, mentoring junior engineers on best practices.
• Be hands-on in Snowflake development, dbt model design, and Fivetran pipeline configuration/administration.
• Explore and pilot GenAI use cases that improve data engineering productivity — e.g., AI-assisted documentation, automated test generation, or natural-language querying over the Snowflake warehouse.
• Ability to work independently with minimal supervision while collaborating cross-functionally with product owners, business stakeholders, and management.
• Provide technical leadership in the development of engineering standards (dbt style guides, naming conventions, testing coverage expectations).
• Comfortable with rapid prototyping and disciplined software development practices (version control, CI/CD, code review for dbt/SQL).
• Perform other duties as assigned.
