Founded in 2015, Oh Polly is a fast-growing, social first fashion brand that creates trend driven, high quality premium products. With a focus on innovation, global responsibility, and ethics. We’ve built a combined social following of over 10 million across our brands, including Bo+Tee; our activewear line. Operating across multiple global offices, we are a dynamic team offering ambitious individuals the chance to thrive, grow, and take their careers to the next level.

The Role

We are looking for a Senior Analytics Engineer (DBT) to take full ownership of the DBT project that powers our Common Data Model (CDM) and business-critical insights.

This role exists because our data models underpin decision-making across Finance, Ecommerce, Operations, and Leadership. We need someone who treats dbt as a production-grade system, not just a transformation layer.

You will be responsible for building, maintaining and governing trustworthy, well-documented and reliable data models that the business can depend on.

Key Responsibilities

• Ownership of the Common Data Model.

• Own the DBT project end-to-end that powers the CDM.

• Be accountable for model correctness, grain, and semantic consistency.

• Ensure models behave predictably for downstream users (Finance, Ecommerce, Operations).

Snapshots & Historical Data

• Own all DBT snapshot logic (SCDs, check vs timestamp strategies).

• Ensure snapshots run reliably and on schedule.

• Validate historical changes are correct, auditable, and complete.

• Prevent silent failures or unnoticed gaps in historical data.

Model Quality & Testing

• Design and maintain robust dbt tests, including: Primary key and uniqueness tests, Accepted values and enums (e.g. brand, lifecycle states).

• Relationship and grain integrity.

• Snapshot invariants.

• Introduce data contracts and guardrails where appropriate.

• Proactively identify and resolve data quality issues before they reach stakeholders.

Observability & Reliability

• Ensure DBT runs are observable, debuggable, and reliable

• Detect and respond to:

• Failed or skipped snapshots

• Unexpected row count changes

• Schema drift

• Partner with platform engineers to improve monitoring and alerting

Change Management & Collaboration

• Manage changes to business logic (e.g. brand rules, lifecycle definitions) in a controlled and documented way.

• Partner closely with Finance, Ecommerce, and Operations to translate requirements into durable data models.

• Review upstream source changes (e.g. Airtable, Shopify, WMS) for downstream impact.

• Act as the point of contact for all Common Data Model–related questions.

Skills & Experience

• Strong, hands-on experience running DBT in production.

• Deep understanding of:
  DBT snapshots and SCD patterns
  Incremental models

• Refactoring models without breaking downstream dependencies.

• Advanced SQL skills (Snowflake preferred).

• Experience supporting high-trust reporting use cases, particularly Finance.

• Comfortable improving and refactoring existing dbt projects.

• Experience with data observability tools.

• Familiarity with systems such as Airtable, Shopify, or operational platforms.

• Experience designing, owning, or evolving a Common Data Model.

• Strong opinions on analytics engineering best practices - and the ability to explain and defend them.
