This is a role for 6 month period - Fixed term
Ryz Labs is looking for a Sr Data Analyst to join one of our client's team , an e-commerce platform.
As their Senior Data Analyst, you'll own the numbers the business actually decides on. Pricing, customer cohorts, payment systems, logistics, marketing channel performance — the analysis behind those calls comes from this seat. You'll work across the full width of a real operating e-commerce business: how visits become orders, how orders become delivered shipments, which customers come back, and what each of those is worth. Your job is not to produce dashboards. It is to produce decisions, and to be the person in the room who knows whether a number is trustworthy.
You'll report into Data & Analytics and work daily with Marketing, Operations, Finance, Customer Experience, and Engineering.
Numeric Defensibility — The Condition of the Seat
In a bootstrapped company, decisions get made on the numbers in front of us, quickly, and often without a second analyst to check the work.

Key Responsibilities
Analysis That Drives Decisions
- Own in-depth analysis across the business: customer base and cohort behavior, pricing, payment systems, logistics and fulfillment performance, and marketing channel efficiency.
- Find the trends, patterns, and anomalies that matter, and separate them from noise — then say what you'd do about it.
- Partner with business-unit leaders, Finance, Operations, and executives to understand the decision behind the request, not just the data pull.
- Bring the recommendation, not only the output. An analysis that ends at "here's the chart" isn't finished.

Data Models, Metrics & Definitions
- Build and maintain the data models that support recurring reporting and business requirements.
- Own the definition of the metrics you produce, and defend those definitions when different teams want the number to mean different things.
- Own the
