As we architect the next wave of data solutions in the AdTech and MarTech sectors, we’re on the lookout for a Senior Data Engineer, an expert in data architecture and pipeline design. If you’re a seasoned expert, eager to lead, innovate, and craft state‑of‑the‑art data solutions, we’re keen to embark on this journey with you.

What you’ll do:

• Develop, test, and maintain data architectures in Snowflake using Python, SQL, and modern data orchestration frameworks to deliver on business requirements.
• Uphold data quality standards, implementing tools and frameworks to detect and rectify data inconsistencies and inaccuracies.
• Optimize pipelines and data structures to ensure peak performance.
• Identify and resolve bottlenecks by refactoring code and/or modifying flows.
• Drive initiatives for new data collection while refining existing data sources, ensuring the highest standards of data integrity, accuracy, and reliability.
• Troubleshoot existing ETL pipelines and work with partners to resolve them in a timely manner.
• Develop and update technical documentation.
• Manage conflicting priorities and multiple projects concurrently.

Who you are:

• 5+ years of intensive experience as a Data Engineer or in a similar role, with a demonstrable track record of leading large‑scale projects.
• Familiarity with Airflow, Dagster or similar data orchestration frameworks.
• Strong understanding of RESTful APIs as well as experience working with both synchronous and asynchronous endpoints.
• Experience with Snowflake or Redshift with a strong understanding of SQL.
• Proficient in Python and Pandas.
• Experience working with JSON and XML.
• Strong understanding of cloud computing concepts and services (AWS preferably).
• Experience with Git or equivalent version control systems and CI/CD pipelines.
• Familiarity with dbt is a plus.
• Highly analytical with strong problem‑solving skills: ability to apply solutions forward, not just completing the task at hand.
• Ability to investigate, analyze and solve problems as well as clearly communicate results.
• Strong attention to detail, well organized, and can prioritize tasks under pressure.
• Must be a team player but also can work independently.
• Experience working in an agile product development environment.
