Senior Data Engineer— Data Cloud Acceleration Team

About the team:

We’re a fast-moving group of business-savvy technologists who value outcomes over ego. We find opportunities, deliver Version 0.1 quickly, measure real impact, and iterate. Some days that means a scrappy prototype; other days it’s a deep dive to de-noise messy data so decisions are trustworthy.

What you’ll do:

• Make messy data decision-ready. Profile, cleanse, reconcile, and document datasets so insights are reliable—even when the inputs are noisy.

• Support new, “tip-of-the-spear” apps. Work with the application team to define the right data ingredients, stand up thin-slice pipelines, and validate results.

• Move fast—carefully. Turn vague asks into testable hypotheses, build the analysis or dashboard, and ship quick iterations with attention to detail.

• Guard data quality. Set up checks, audits, and alerts; track issues to closure and raise the bar on definitions, lineage, and reproducibility.

• Automate the repetitive. Use SQL/Python (plus Airflow/Prefect/dbt or similar) to turn one-off analyses into lightweight, maintainable workflows.

• Tell the story. Present findings with clear business context; highlight signal vs. noise, trade-offs, and recommended next steps.

• Partner across functions. Collaborate with product, engineering, and client teams to ensure what we build solves real problems.

• Utilize AI to improve business functions. Apart from automation, work with AI during project delivery and data mining

What sets you up for success:

None of these are hard gates—but they paint the picture.

• Analytics craft: Advanced SQL (window functions, CTEs, performance tuning); strong exploratory analysis and sanitychecking instincts.

• Self-learning and self-upgrade. Continuously learn as you go and work with the team to onboard on to new data and tools.

• Data quality mindset: Experience with data testing/validation (e.g., Great Expectations, dbt tests, custom checks), metric definitions, and documentation.

• Automation: Comfortable turning notebooks into repeatable jobs with Python; basic orchestration (Airflow) and CIfriendly habits.

• Platforms: Familiar with cloud data warehouses/lakes (Snowflake, BigQuery, Athena, Hive, Databricks—or equivalents).

• Business lens: You naturally connect analyses to KPIs, revenue, cost, and customer impact.

• Communication: Sharp clarifying questions, concise write-ups, and the ability to translate between tech and business.

You’ll thrive here if you…

• Think pragmatically. You pick the simplest solution that gets the job done today—and improve it tomorrow.

• Prototype loudly. You prefer shipping a clear v0.1 to debating a perfect v1.0.

• Sweat the details. You double-check the join keys and the denominator before the demo.

• Seek clarity from ambiguity. You turn fuzzy requests into crisp metrics and next steps.

• Share the playbook. You document as you go so others can build on your work.

90-day markers of success

• A small but solid data-quality checklist adopted on at least one key pipeline.

• One or two POC intelligence applications supported with documented data ingredients, validation steps, and dashboards.

• A repeatable automation that replaces a recurring manual analysis.

• A short wins log showing how your work improved accuracy, speed, or business outcomes
