Director, Data & AI Platform Engineering

Stitch Fix

About The Position

We’re hiring a Director of Data & AI Platform Engineering to lead the organization that designs and operates Stitch Fix’s core data, machine learning, and generative AI platforms. You will set the vision and drive the technical direction for the systems that make AI-powered, data-driven experiences possible across the company - enabling richer personalization, better decision-making, intelligent automation and, and enterprise-wide innovation. You will help evolve our technical foundation to support next-gen AI use cases - unified signals, dynamic and context-aware models, semantic understanding, retrieval-based intelligence, and evolved ML workflows. This is a highly visible role that will partner closely with both technology and business teams to accelerate innovation and power the next chapter of Stitch Fix’s AI-enabled experiences.

Requirements

10+ years in software, data, ML, or platform engineering; 5+ years leading engineering managers or multi-team platform groups.
Demonstrated success owning large-scale data platforms, ML platforms, or AI/GenAI platforms in cloud environments.
Experience driving platform modernization, unification, and multi-year architectural transformation.
Strong software engineering foundation, with experience designing and building large-scale distributed systems and resilient, high-quality APIs and services using modern programming languages and cloud-native architectures.
Strong track record operating and evolving modern data infrastructure, including distributed compute and storage technologies (Spark, Trino, Iceberg), real-time processing frameworks (Kafka/Flink), metadata / catalog systems, and Kubernetes-based orchestration.
Deep expertise across the ML lifecycle - feature engineering, training pipelines, model deployment and serving, monitoring, validation, fine-tuning, and MLOps best practices.
Proven capability in building self-service platform abstractions and tooling that enable teams to develop, experiment, and deploy data and ML products efficiently.
Experience with modern GenAI architectures - semantic retrieval, knowledge-grounded indexing, LLM orchestration, agent workflows, and evaluation frameworks.
Strategic thinker able to align platform investments with business priorities and emerging AI opportunities.
Strong people leader with a track record of building inclusive, high-performing engineering teams.
Excellent communicator who can influence both technical and business stakeholders at all levels.

Nice To Haves

Familiarity with modern ML frameworks like PyTorch and Ray is a plus.

Responsibilities

Lead the strategy and execution for Stitch Fix’s next-gen Data, ML, and GenAI platforms - building a unified, secure and scalable architecture for semantic search, retrieval-based intelligence, multi-model orchestration, and agent automation, while operationalizing GenAI through safe, performant, and production-ready systems that power real-world client and employee experiences.
Drive modernization of data and ML foundations to support unified signals, adaptive models, experimentation velocity, and scalable AI/ML workloads.
Provide foundational APIs, SDKs, frameworks, and self-service tools that make it easy for data scientists, ML engineers, analysts, and application teams to build and deploy AI solutions quickly, safely, and at scale.
Partner with Data Science, Engineering, and Product teams to translate Data/ML/GenAI platform capabilities into production-grade features and intelligent experiences that deliver measurable business value.
Drive responsible, enterprise-wide AI and data adoption by creating reusable templates, documentation, and enablement programs, and by partnering closely with technology and business teams to identify and prioritize high-impact opportunities for personalization, automation, and intelligence.
Establish strong governance practices including data contracts, lineage, metric definitions, access policies, and responsible AI guardrails - for trust, safety, and compliance.
Ensure operational excellence through platform reliability, performance, observability, cost efficiency, and simplification of legacy systems.
Lead and develop high-performing engineering teams fostering a culture of clarity, excellence, and trust.
Balance speed of innovation with platform stability, ensuring engineering efforts are tightly aligned to business priorities and long-term client value.
