Stitch Fix is a personal styling service that offers a unique and personalized approach to fashion for women, men, and kids. Clients start by taking a style quiz, which helps Stitch Fix understand their preferences, sizes, and budget. Based on this information, a personal stylist selects five personalized clothing pieces that are shipped directly to the client's door. Customers can choose to keep and purchase any items they like, with the $20 styling fee applicable to kept items. Stitch Fix carries a wide range of sizes and offers free shipping and returns. The service is flexible, with no subscription required, allowing customers to order style boxes on demand or at regular intervals. Stitch Fix also offers a 'Freestyle' shopping option where clients can browse curated suggestions based on their preferences. The company covers a wide variety of styles from numerous brands, ensuring there are options to suit various fashion tastes and needs.

📋 Description

• As the Senior Lead Engineer on Fulfillment Platform, you will help to set the technical direction for the systems that orchestrate Stitch Fix’s warehouse and transportation networks. • You will focus on development and roadmapping against key application enhancements to support floor efficiency, accuracy, and system reliability—all while mentoring engineers and driving industry best practices. • Your work will directly influence how quickly and economically we delight clients, unlock inventory, and grow our margins. • Influence the evolution of our multi-carrier shipping platform—rate shopping, label generation, tracking ingestion, and returns workflows. • Design fault-tolerant services that reconcile hundreds of thousands of carrier events per day and surface real-time shipment status to downstream systems. • Ensure comprehensive visibility into warehouse operations and precise ingestion of new merchandise. • Mentor engineers through code reviews, design sessions, and thoughtful feedback, fostering a culture of high standards and continuous learning. • Instrument, monitor, and tune our services for reliability, latency, and cost. • Translate business goals (cost, delivery promise) into technical roadmaps that balance short-term wins with long-term scalability.

🎯 Requirements

• You have 5-8 years of software engineering experience. • You have proven experience designing large-scale, event-driven or distributed systems (ideally in fulfillment, logistics or e-commerce). • You have experience implementing and managing integrations with a wide range of external logistics and technology partners that power warehouse and transportation operations. • You have a track record of leading engineers through ambiguous, cross-functional projects and delivering production software that moves key business metrics. • You have fluency in at least one modern programming language (we primarily use Ruby, Go, and Python, but value great engineers over great syntax). • You have proven experience with relational databases (e.g., Postgres, MySQL) plus a knack for picking up new technologies fast. • You have built production services on a major cloud platform - AWS, GCP, Azure or similar, and are highly skilled with modern observability stacks like Datadog. • You have practical knowledge of optimization, forecasting, or decision-science techniques—and the humility to partner with specialists when needed. • You have a bias for automated testing, continuous delivery, and observability as non-negotiable facets of quality. • You have strong communication skills—able to translate between technical details and business outcomes for stakeholders at every level.

🏖️ Benefits

• This role will receive a competitive salary, benefits, and equity. • The position is eligible for medical, dental, vision, and other benefits. • This position is eligible for new hire and ongoing grants of restricted stock units depending on employee and company performance. • Applicants should apply via our internal or external careers site.
