Job description

About Stitch Fix, Inc.

Stitch Fix (NASDAQ: SFIX) Stitch Fix is redefining retail by combining human creativity with advanced data science and Generative AI. As we build the future of personalized shopping, we’re equally committed to building yours. We believe in investing in our team as much as our technology. Join us to be a trendsetter in the industry and help us redefine what’s possible for our clients, while we help you reach your full potential.

About The Role

The Decisions & Insights team empowers teams across Stitch Fix with objective, high-impact insights and intelligent self-service tools that improve how we understand clients and make decisions. Using experimentation, causal inference, advanced analytics, and AI, the team goes beyond understanding what happened to uncover why it happened and what we should do next.

In this role, you will partner with teams across Client Experience, Strategy, Marketing, Styling, Client Support, and Engineering to turn complex data into actionable business strategy. You will design and analyze experiments and observational studies, uncover differentiated insights from Stitch Fix's rich structured and unstructured data, and build repeatable analytical workflows and systems that scale those learnings across the organization. You’ll independently own high-impact problems from initial framing through delivery, combining technical depth, business judgment, and strong communication to influence decisions and drive measurable outcomes.

What You’ll Do

• Develop sophisticated statistical models, experiments, and causal inference approaches that uncover the drivers of client and business outcomes and inform high-impact decisions.
• Build scalable analytical capabilities—including semantic layers, entity models, and repeatable workflows that connect fragmented data and enable analytics, predictive modeling, AI applications, and self-service decision-making.
• Own complex, ambiguous analytical initiatives from problem definition through execution, measurement, and communication, translating findings into clear recommendations and executive-ready narratives.
• Partner with Client Experience, Strategy, Marketing, Styling, Engineering, and other cross‑functional teams to define success metrics, understand client journeys and behaviors, and identify opportunities to improve products and experiences.
• Advance the team’s technical capabilities by mentoring other Data Scientists and leveraging LLMs, AI agents, and emerging tools to accelerate analysis, improve workflows, and raise the bar for experimentation, modeling, and technical excellence.

About You

This is what you’ll need to succeed in this role from day 1:

• You have 3+ years of experience in a data science role, ideally within the e‑commerce or retail industry.
• You have experience leveraging graph database technologies to build comprehensive 360‑degree views of core business entities, significantly improving multi‑modal data discovery, contextual search, and downstream AI reasoning across interconnected domains.
• You have experience with product analytics, product event tracking, and user behavior mapping to guide product strategy and feature development.
• You hold a Bachelors or Masters degree in Statistics, Data Science, Computer Science, or a related quantitative field.
• You are proficient in Python or R and have experience writing SQL in collaborative, production‑oriented environments.
• You are a strong communicator who can simplify complex technical concepts to drive alignment and action with business partners.
• You know how to leverage LLMs and AI agents as thought partners to streamline workflows, document effective prompt frameworks, and accelerate problem‑solving across small tasks and large initiatives.
• You thrive in ambiguity, with a proven ability to own and drive projects from initial concept to delivery.
• You have a solid foundation in experimentation and causal inference, with the ability to link model performance directly to business outcomes.
• You are curious, pragmatic, and motivated to continuously raise the bar for technical excellence for yourself and your team.

Why You’ll Love Working at Stitch Fix

• We are a group of bright, kind people who are motivated by challenge. We value integrity, innovation and trust. You’ll bring these characteristics to life in everything you do at Stitch Fix.
• We cultivate a community of diverse perspectives—all voices are heard and valued.
• We are an innovative company and leverage our strengths in fashion and tech to disrupt the future of retail.
• We win as a team, commit to our work, and celebrate grit together because we value strong relationships.
• We boldly create the future while keeping equity and sustainability at the center of all that we do.
