About MashginMashgin powers the world's best checkout experience for over 40 million users. Customers just place their items on our kiosks and our AI rings up their entire order in less than a second. With Mashgin, lines are now optional.Mashgin's technology powers over 1 billion transactions at your favorite locations, including over half of all US professional sports teams, 4,000 convenience stores, major airports, universities, and more.We’re not just building cutting-edge AI—we’re creating real-world impact and unforgettable experiences. Backed by a well-funded Series B, we’re also one of the rare AI startups that’s already profitable.Our secret? A culture of extreme ownership, autonomy, and customer obsession. At Mashgin, we are building something extraordinary by challenging conventional wisdom. We’ve thrown out the old rules to focus on what truly matters: creating a kickass product that makes people say, 'Wow'. We don’t care about short-term wins; we build systems that stand the test of time. If you thrive in a culture of excellence without compromise and want to see your work have an immediate, remarkable impact, you’re in the right place.Position SummaryThis 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 TodayReporting & 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.What We Value:Impact: You will own significant responsibility and have total ownership over your work. We stay lean and efficient, so your work directly impacts the product we ship every daySimplicity: Complexity is a waste of time here—we take pride in building things that just workHard Work: Forget the glamorous research papers. We prioritize the hard work it takes to achieve real-world clarity and accuracy. You will innovate relentlessly to push the boundaries of what’s possible in visual automationHumility: No task is beneath you. Whether it's high-level architecture or grunt work to fix a bug, we check our egos at the door and get real work doneRuthless Prioritization: If everything is on fire, nothing is. You will be expected to prioritize ruthlessly, cutting through distractions to focus on the most impactful product improvementsCustomer Innovation: We are customer-centric, not customer-pleasing. You won’t bend to every client demand; you will let innovation drive the product forward to solve the real problems our users faceEfficiency: Meetings suck. We keep them short and only use them for alignment, giving you your time back to focus on real workWhat You'll DoOwn products, not tickets. Take a problem from "we heard this from customers" to "it's live in 4,000 locations." You decide what to build, how to build it, and when to ship. You'll work directly with the founders on product development from end to endTalk to customers. Visit kiosk deployments, sit with operators, watch transactions happen, and understand pain points firsthand — not through a requirements docDesign the experience. Sketch UIs, prototype interactions, and make product decisions. You don't need to be a trained designer, but you need taste and empathy for the person standing at the kioskBuild simple MVPs and ship them quickly from 0 to 1. Dream up new architecture to solve challenging problems. Rethink and recreate existing codebases for scaleWrite great code. Full-stack: React/TypeScript for kiosk UIs and dashboards, Python for backend services and ML pipelines, C++ for on-device inference. You don't need all of these today, but you need to be comfortable learning new languages, libraries, and frameworks when the solution calls for itBuild with AI. Use LLMs, copilots, and AI development tools to move at 10x speed. Understand how to leverage AI models in production — not just as toys. You get an unlimited token budget as long as you keep shipping great workSolve hard problems at the intersection of hardware and software. Work with a small interdisciplinary team in hardware, software, and design to build new versions of products from scratch. Deal with edge cases that only happen in a stadium during the 7th-inning stretch. Make systems that recover gracefullySupport what you ship. When something breaks at a customer site, you feel it. Continuously improve and maintain code that's already in productionWho You AreYou're a builder at heart. You'd be building software even if nobody paid you. You have side projects, open source contributions, or a startup in your past (or future)You're deeply technical. 5+ years shipping production software. Excellent knowledge of one or more of: Python, Node.js, C++, Go, C#, Java. Experience building production-ready code that's used regularly by lots of peopleYou think like a product person. You don't just ask "how should I build this?" — you ask "should we build this at all?" and "what would make this 10x better for the user?"You have taste. You care about the details — the animation speed, the error message copy, the API naming convention. Craft mattersYou move fast. You bias toward action. Ship MVPs, get feedback, iterate. You'd rather have something in front of users in a week than a perfect spec in a monthYou're comfortable with ambiguity. We won't hand you a fully-specced PRD. You'll figure out what the right thing to build is, often with incomplete informationYou use AI as a multiplier. You're fluent with AI-assisted development tools and understand how to use LLMs to accelerate your workflow — from code generation to prototyping to analysisYou can go start a company. This is the litmus test.
