About The Position

Instacart’s Home & Cross-Retailer Search teams are responsible for how customers first discover where and what to shop: from the personalized Home experience to search across thousands of retailers and items. We own the systems that decide which retailers, items, and content to show, how fast they appear, and how well they match customer intent across platforms. You will own the web platform architecture that powers discovery at scale: defining how our frontend systems are structured, how data flows from server to client, and how we make those experiences fast and reliable across platforms. This is a high-scope role that spans multiple product surfaces and requires close collaboration with engineering, product, design, and machine learning teams.

Requirements

Extensive experience in a senior/staff engineer role with a strong focus on web systems design and frontend architecture.
Deep expertise in modern web technologies (React, TypeScript, Next.js etc.) with the ability to reason about end-to-end system architecture across client and server.
Proven experience designing and operating large-scale web platforms supporting multiple product surfaces.
Ability to dive deep into web performance optimization rendering, Core Web Vitals, bundle size, caching strategies, and client-side data fetching.
Experience leading engineering design reviews and influencing technical decisions across teams.
Experience building web systems used and maintained by large engineering organizations (30+ engineers).
Strong communication skills and the ability to influence technical strategy across organizational boundaries.
Track record of mentoring engineers and driving long-term technical vision.

Nice To Haves

Experience in Search, Recommendations, Personalization, or related discovery platforms is a huge plus.
