About The Role

  • 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. This is a builder
  • role, not a people manager role.
  • You’ll be expected to move quickly, work scrappily, and take ownership from problem definition
  • through implementation. This role is ideal 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 insights.

What We’re Looking For

  • 5–10+ years of experience in data engineering, analytics engineering, or advanced

analytics roles.

  • Strong experience with GCP and BigQuery, including materialized views, scheduled

queries, and large-scale SQL optimization.

  • Experience with modern data ingestion tools—Airbyte (Cloud or OSS) strongly preferred;
  • comfort managing connectors, debugging sync failures, and building validation
  • frameworks.
  • Strong proficiency in SQL and data modeling, with comfort using AI tools (e.g., Claude
  • Code) to accelerate development. You should be fluent in CTEs, window functions,
  • UNION ALL patterns, date-spine techniques, and anti-join logic.
  • Proven experience supporting financial reporting and working closely with finance
  • teams—P&L reconciliation, COGS analysis, revenue waterfalls, and unit-economics
  • datasets.
  • Experience building dashboards and reporting in modern BI tools.
  • Familiarity with AI workflows and building structured datasets for LLM-powered agents.
  • Experience working across multiple business domains (ops, marketing, finance, product,

etc.).

  • Strong ownership mindset with the ability to operate independently.
  • Comfortable in a fast-paced, ambiguous environment with shifting priorities.

Bonus Points

  • Experience with ERP or inventory management systems (especially warehouse/3PL

integrations).

  • Experience in ecommerce, recommerce, logistics, or marketplace

businesses—especially Shopify-based platforms.

  • Familiarity with multi-touch attribution, post-purchase surveys (e.g., Fairing/PPS), or

event-level GA4 data.

  • Experience with customer cohort analysis, retention modeling, or LTV forecasting.
  • Exposure to pricing, inventory aging, or supply chain/fulfillment data systems.
  • Experience with Klaviyo, Attentive, or similar lifecycle marketing data integrations.
  • Familiarity with demographic enrichment tools or custom API connector development.
