About The Position

The Staff Content Designer, Model Design for CoreX is one of our highest-impact roles where you'll shape how AI models interact with users across Instacart's core consumer experiences. You will view the model as the product itself, striking a delicate balance between maximizing the model's capabilities, reading between the lines in user queries to understand how best to help, and upholding user trust.
You'll embed with our Agentic design team and be part of the team reimagining the online grocery experience. You will collaborate closely with researchers to understand, predict, and design model behavior, while partnering with product managers, engineers, and designers across the company to ensure we're creating agentic experiences that solve and anticipate our customers' needs. This role requires exceptional taste, creativity, and writing skills combined with deep technical intuition to craft AI interactions that delight users and feel truly helpful.
As a general standard for all our designers and leaders, we are looking for people who thrive on building a strong design culture, lead with empathy and collaboration, and are committed to pushing the boundaries of quality and innovation in everything we ship. You'll be joining us in defining and evolving the newly established model design function at Instacart.

• Deep knowledge of how information architecture and visual-verbal design work together to create coherent product experiences.

• Technical fluency to understand how data composition, training approaches, and prompt modifications influence AI behavior and output quality.
• Strategic thinker who bridges user research, product goals, and business objectives to create language frameworks and UX copy that solve real problems.
• Self-directed operator who thrives in ambiguous, fast-moving environments, making smart tradeoffs and maintaining high standards without close supervision.
