Overview

Instacart’s Stores Intelligence organization is building the operating system for brick-and-mortar grocery. As a Senior iOS Engineer on the In-Store Mode team, you will build the mobile experience that helps people shop in physical grocery stores. Customers plan the trip at home, then use the same app in the aisle to find items, discover deals, and use their loyalty rewards.

What makes the engineering interesting:

• One experience, many apps: In-Store Mode runs inside many grocers' branded apps and blends native iOS with web, so you'll design for flexibility, consistency, and a clear boundary between the two.
• The physical world is challenging: The same feature has to work in a small neighborhood market and a large wholesale store, with very different layouts, assortments, and shopping habits, while powering in-store navigation and discovery.

About the Job

• Lead iOS projects end to end, from technical design and rollout strategy through production operations and debugging.
• Shape product requirements by bringing a technical perspective and making trade-offs between scope, quality, and timeline.
• Build and maintain integrations between native iOS code and web content.
• Use AI-assisted and agentic development tools to boost your own and the team's productivity, and suggest improvements to how the team builds.
• Collaborate with engineers, designers, data scientists, and PMs across teams to align goals and deliver cross-functional outcomes.
