Position Summary This is not a specialized position. We're hiring Builders — people who can wear every hat and ship products that blow people's minds. Most companies split this across five roles: a PM to decide what to build, a designer to figure out how it looks, a frontend engineer, a backend engineer, and someone to handle support when it breaks. We don't do that. At Mashgin, one person owns the whole thing — from talking to a stadium operations manager about their pain points, to sketching a solution, to writing the code that runs on thousands of kiosks, to watching real users interact with it and iterating until it's right. You'll work across our entire stack: the computer vision models running on-device, the kiosk UI that a customer touches, the cloud infrastructure processing a million transactions a day, the dashboards operators use to manage their locations. You'll use AI tools to move at 10x speed, but you'll understand what's happening under the hood. If you could credibly start a company tomorrow and do every job yourself — engineering, design, product, support — you're the kind of person we're looking for. We maintain a flat, high-impact engineering culture where every engineer who joins our team carries the title of Member of Technical Staff. Where We Need Builders Today Reporting & Management Application. Own the application our customers use to understand their business — reporting dashboards, transaction analytics, location management, and operational tools. This requires a deep understanding of data, visualization, and customer processes. You'll need to get inside the heads of stadium operators, c-store managers, and university dining directors to understand what numbers matter to them and how to surface insights that drive real decisions. Not just charts — the whole product experience around the data. Creator (Menu Management UI). Own Creator, our menu management platform — the tool operators use to configure what their kiosks recognize, how items are priced, and how menus are organized. This is an incredibly complex workflow (think: thousands of SKUs, regional variations, seasonal rotations, tax rules, modifier chains) that needs to feel simple to a normal human end user. If you love the challenge of taking gnarly domain complexity and making it disappear behind an interface that a non-technical operator can use without training, this is your role.
