Senior Software Engineer

Wonder

10d•$176,000 - $183,500

About The Position

Every meal Wonder delivers starts as a chain of decisions — forecasting demand, sourcing ingredients, scheduling production, managing inventory across facilities, and coordinating fulfillment down to the minute. These decisions span dozens of facilities, hundreds of operators, and a supply chain that is growing in both scale and complexity. When the software behind these decisions is fast, correct, and easy to use, food moves through the system efficiently and customers get exactly what they ordered. When it isn't, food is wasted, orders go short, and the experience breaks down. We're looking for a product-minded senior engineer to build the systems and interfaces that keep this supply chain running. You will be a key individual contributor on our Supply Chain Technology team, working across the full stack — from the backend services that orchestrate ordering, production, and fulfillment workflows to the operational interfaces that planners, buyers, and floor operators rely on every day. You'll own features end-to-end: designing the data model, building the service, wiring up the API, and shipping the UI that puts it in front of operators. This is a true fullstack role. You'll move between backend services and frontend applications depending on where the most impactful work is, and you'll develop depth across both. You'll partner closely with product, design, data, and operations teams, and you'll have room to grow into a technical lead across the Supply Chain organization.

Requirements

Proficiency in a modern frontend framework (Next.js with TypeScript).
Strong problem-solving skills and the ability to troubleshoot complex technical challenges across the stack.
Excellent communication and interpersonal skills, including the ability to lead technical discussions with product, design, and operations partners.
