Stitch Fix Engineering and Data Science

We are reinventing the retail industry through innovative technology.

We're a full-stack startup creating unique solutions in data-driven merchandising, massively scaled personal styling, and complex logistics. We value very lightweight planning, continuous deployment, little tech debt, no product managers.


Our multi-app, event-driven application architecture drives both scale and flexibility.

Many applications and services

There are no monoliths here. Each application in our platform has a clear and distinct purpose and all of them are built in house. That means small, clean code bases with little technical debt and lots of flexibility. We use RabbitMQ to send messages about real-world events to other apps which decide whether or not to do something with them. This de-coupled, asynchronous architecture allows us to scale with ease and add or change components as needed. When it really makes sense we will build a RESTful API to wrap a service requiring an immediate response.

Product is our primary concern

We hire engineers with great Product instincts because we are also the Product team: building great software is a collaborative effort so we work directly with stakeholders in the business. We are a central part of the business so we deliver real value and not just features, and because we understand how Stitch Fix works we are trusted to focus our time and effort where they are most needed.

More about Stitch Fix Engineering

We use technologies like PostgreSQL, Redis, ElasticSearch and RabbitMQ along with various private Gems to tie them all together. We work from San Francisco, Pittsburgh and remotely, and we use Heroku, GitHub, Google Hangouts and HipChat to help us build it all.

We are looking for people who share our values. We like to move quickly and ship lots of code, but in a considered way. We use TDD, CI and an all-hands-on-deck approach to Pull Requests to ensure we can keep the pace up without stinging on quality.

If any of us have a good idea for introducing a new technology or pattern then we go ahead and run an experiment. The debates don’t start until we have some real evidence to look at and since we avoid dogma and evangelism they tend to be short.

We work closely with our internal partners and we assume that they know best about what they need to do their jobs. Our job is to solve business problems and some of our proudest moments come from solving those problems without a line of code.

Data Science

We breath data, do awesome data science and engineering, and develop cutting-edge algorithms.


At Stitch Fix we’re pioneering uncharted territories. Data is the fundamental unit of our business model and to succeed we have some of the brightest and most highly motivated individuals on our team. It’s in our nature to get things done, formulate novel and creative solutions to complex problems, and communicate our results through awesome visualizations.


We commit to our recommendations by physically delivering them to our clients. Our business requires a mix of art and science in everything we do: from buying inventory to sending the right items to the right clients.


Bright, Kind, Goal-oriented.


We have really interesting problems to solve due to our unique business model and hire really bright people to tackle them. If it were easy everyone would be doing it, right? We start with problems and goals and work collaboratively to come to the right solutions.


It's not just being clever that makes you a good fit at Stitch Fix. We really value how well our team works together and kindness a huge part of it. Working with people we enjoy being around and that make us excited to start work each day is a big part of our success.


We love people who are driven and self-motivated. We are a largely flat organization and value autonomy combined with results. No one likes to be micro-managed and we don't want to manage people that way either.
