Data Engineer

Ready to build the data foundation powering the future of online fashion?

We’re looking for a self-starting Data Engineer to shape, scale, and optimise Otrium’s modern data platform. You’ll work at the heart of our data ecosystem — designing strong data models, improving data quality, and enabling analytics, personalisation, and machine learning across the company.

You won’t just maintain pipelines — you’ll build the future of how Otrium leverages data to drive smarter decisions and personalised experiences.

Your Impact

• As our Data Engineer, you’ll be a key builder behind Otrium’s data ecosystem. You’ll develop high-quality data pipelines, own our transformation layer, and ensure reliable, scalable data foundations for commercial, product, marketing, supply chain, and data products teams.
• You’ll work extensively within our state-of-the-art stack — Databricks, dbt, Fivetran, and Hightouch — and collaborate closely with analytics, data products, engineering, and business stakeholders to bring clean, trustworthy, actionable data to everyone at Otrium.
• You’ll report to the Lead Data Engineer and play a key role in evolving Otrium’s data architecture, infrastructure, and best practices.

• Champion data quality and consistency across the organisation.

Data Integrations & Reverse ETL

Collaboration & Enablement

• Partner with marketing, commercial, finance, supply chain, product, and engineering teams to understand requirements and translate them into robust, scalable data solutions.
• Support analysts and data scientists with well-structured datasets, documentation, and tooling best practices.

Innovation & Continuous Improvement

• Identify opportunities to automate manual processes and improve data workflows.
• Contribute to the evolution of our platform architecture, helping us stay ahead of the curve with modern data technologies.
