About the Team

At Stitch Fix, our data science team combines machine learning with expert human judgment to generate innovative recommendations and insights that transform the way our clients discover what they love. We believe in a curiosity-driven, data science culture where members have autonomy to deliver impact through end-to-end, full-stack product development and ownership. The diversity of the problems that we work on and the data-rich environment of our business make it possible, even essential, to bring the tools of multiple disciplines to bear on our hardest problems. We are looking for data scientists and leaders to join us as we revolutionize retail.

The Global Optimization team is connecting the dots for our clients and inventory. We seek to ensure that Stitch Fix’s systems are operating at their global optimum rather than at local optima. The team owns distribution of inventory among clients so that the outcomes for all clients are simultaneously considered given inventory constraints. We also own the optimization engine that will power making several critical decisions based on client demand, for example merchandise buying and allocation. We partner with Product Managers, Merchandise Planners & Buyers as well as other Algorithm teams to build central tools that cut across organizational and functional boundaries of the company.

About the Role

As a Staff Machine Learning Data Scientist in the Global Optimization team, you will design, implement and validate improvements to both inventory distribution and optimization engine based on client demand to scale the impact to broader Stitch Fix. You will be responsible for maintaining production systems that power various use cases, and follow strong engineering principles to keep the maintenance low on the team.

This team has considerable opportunity for impact, by enabling all merchandise buying decisions based on client demand and fundamentally changing the way we evaluate inventory health across the company.

You're excited about this opportunity because you will…

• Leverage your skills in data analysis, solving optimization problems, building production ready code, and running A/B tests.

• Operate as a full stack data scientist participating in every stage of development from idea, analysis, proof of principle to putting into production with strong engineering practices
• Leverage the client-product matching information provided by the inventory targeting algorithm to enhance cross-team visibility into product and client performance to improve all stages of the client and merchandise lifecycles.

We’re excited about you because…

• Are an expert in data science, e.g. not just fitting a model but being held accountable for creating business value.
• Have extensive experience developing and maintaining applications to drive business decisions in production systems.
• Have an ability to frame complex problems and generate strategic options leveraging the data when it is available or offering creative and pragmatic alternatives when it is not
