• Integrate data from diverse sources, including databases, APIs, flat files and cloud platforms.
• Design and build performant, scalable data pipelines using tools like dbt, Fivetran, and Airflow.
• Troubleshoot issues with production data pipelines and implement monitoring and alerting as needed.
• Design and deliver curated datasets to support analytics engineers in building AI and BI solutions.

Collaboration & Data Quality (10%)

• Collaborate across business, governance, QA and analytics teams to ensure data quality, consistency and successful solution delivery.
• Implement data quality frameworks and automated tests to ensure integrity, trust and traceability across the pipeline.

Technology Best Practices & Innovation (15%)

• Define and implement enterprise‑scale data engineering best practices, standards and guidelines across the development life cycle.
• Stay up to date on the latest data engineering trends and technologies, advocate for new technologies and champion their adoption to continuously improve our data infrastructure.

Qualifications

• Education: Bachelor’s degree in computer science, data science, software engineering, information systems or related quantitative field; master’s degree preferred.
• Experience: 10+ years of data engineering experience, with at least 3 years in a modern cloud/data stack. Demonstrated experience designing and implementing enterprise‑scale data platforms.
• Technical Proficiency: Proficient in data management disciplines, including data integration, modeling, building data warehouses/lakes and data quality, or other areas relevant to data engineering responsibilities and tasks.
• Communication & Mindset: Strong communication skills, to be able to clearly articulate technical concepts to non‑technical stakeholders. Strong problem‑solving skills and a proactive, ownership‑driven mindset.
• Skills:
  • Proficiency in the design and implementation of modern data architectures such as cloud services (AWS, Azure, GCP) and modern data warehouse technologies (Snowflake, Databricks, Redshift, BigQuery). Experience with AWS and Snowflake preferred.
  • Experience with ETL/ELT design and development using tools such as Informatica, Matillion, AWS Glue or equivalent. Experience with Fivetran and dbt preferred.
  • Strong experience with database/big‑data technologies such as Oracle, SQL Server, Teradata, Apache Spark, Delta Lake and Hadoop.
  • Experience with DevOps/DataOps, CI/CD principles and technologies using tools such as BitBucket, Jenkins or similar.
  • Experience with Agile methodologies, common scrum practices and tools.
  • Familiarity with data quality and testing frameworks (e.g. dbt tests, Great Expectations, Soda) is a plus.
