At Ryz Labs, we’re looking for a hands‑on Senior Data Engineer / Analytics Engineer to own and evolve one of our clients’ data platforms, reporting layer, and AI‑driven data capabilities. You’ll report directly to the Head of Data & Analytics and operate as a high‑impact individual contributor across finance, operations, merchandising, marketing, and product.

You’ll be expected to move quickly, work scrappily, and take ownership from problem definition through implementation. This role is idóneo for someone who thrives in a startup or scale‑up environment, where speed, iteration, and pragmatism matter more than perfection.
What You’ll Do
- Own and evolve data architecture across ingestion, transformation, and reporting layers, with a centralized cloud data warehouse.
- Build and maintain scalable data pipelines across a variety of internal and external data sources, ensuring reliability, completeness, and accuracy.
- Develop robust validation frameworks to monitor data quality and quickly identify issues.




- Write and optimize complex SQL to power analytics, reporting, and business decision‑making.
- Design and maintain data models that support financial reporting, operational analytics, and merchandising insights.
- Partner closely with Finance to ensure accurate, reconcilable reporting across revenue, costs, and unit economics.
- Build and maintain dashboards and reporting used by leadership to drive decisions across the company.
- Identify and resolve data issues quickly, balancing speed and accuracy in a fast‑moving environment.
- Support integrations between core business systems and ensure clean, consistent data across platforms.
- Explore and implement AI‑driven workflows that enhance data accessibility and decision‑making.
- Automate manual reporting processes and improve operational efficiency across teams.
- Act as a cross‑functional partner, translating ambiguous business questions into clear, actionable in
