Sr. Design Technologist , eShop Content Services

We are looking for a Design Technologist III to lead the development of Generative AI-powered tools, build custom functionalities from the ground up, and drive foundational model training initiatives tailored to design and creative production tasks. This is a senior individual contributor role for someone who can independently architect and build end-to-end GenAI solutions, lead foundational model training for design-specific use cases, and set the technical direction for AI-driven content creation.

This Role Is for You If You Want To

• Lead the training, fine-tuning, and evaluation of foundational models purpose-built for design and visual content tasks
• Architect and build production-grade GenAI tools and platforms from scratch
• Define the technical roadmap for AI-powered content generation at scale
• Drive adoption of Generative AI across creative production workflows
• Partner with applied scientists, ML engineers, and creative leaders to push the frontier of AI-driven design


Key job responsibilities
• Lead foundational model training - Design, train, fine-tune, and evaluate foundational models and LLMs for design-specific tasks including image generation, video synthesis, style transfer, and content enhancement
• Build custom GenAI functionalities - Architect and develop production-ready tools, APIs, and platforms from the ground up to serve creative teams at scale
• Own the technical roadmap - Define and drive the long-term technical vision for GenAI adoption across visual content production
• Develop and optimize AI pipelines - Build end-to-end inference and training pipelines leveraging cloud-based ML platforms
• Drive experimentation and R&D - Lead research efforts to evaluate emerging models, architectures, and techniques (diffusion models, multimodal models, LoRA/PEFT fine-tuning) for production applicability
• Establish best practices - Define standards for prompt engineering, model evaluation, data curation, and quality benchmarking across GenAI workflows
• Mentor and influence - Provide technical leadership and mentorship to junior design technologists and raise the bar on technical excellence
• Stakeholder partnership - Collaborate with applied science teams, product managers, and creative leadership to align AI capabilities with business goals and customer needs


A day in the life
A typical day as a Design Technologist III could include leading a model fine-tuning session for a custom image generation model, architecting a new service to deliver AI-generated content at scale, evaluating the latest open-source models for production readiness, building custom LoRA adapters for domain-specific style transfer, or reviewing technical designs with engineering and science partners. You might also spend time defining training data strategies, building evaluation frameworks for generated content quality, or prototyping new AI-powered creative tools. You are expected to operate with high ambiguity, make sound technical judgments independently, and influence across teams.
