Builder

Mashgin•Palo Alto, CA

1d•$185,000 - $275,000

About The Position

This is not a specialized position. We're hiring Builders â 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 â 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 â engineering, design, product, support â 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 â 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 â the whole product experience around the data. Creator (Menu Management UI). Own Creator, our menu management platform â 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.

Requirements

You'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 people.
You think like a product person. You don't just ask "how should I build this?" â 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 â the animation speed, the error message copy, the API naming convention. Craft matters.
You 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 month.
You'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 information.
You use AI as a multiplier. You're fluent with AI-assisted development tools and understand how to use LLMs to accelerate your workflow â from code generation to prototyping to analysis.
You can go start a company. This is the litmus test. If you could credibly do every job at a startup â engineering, design, product, customer support â you're the kind of person we're looking for.

Nice To Haves

Experience in a fast-paced work environment, shipping quality code quickly and iterating
Comfortable with deploying and managing cloud infrastructure
Experience with computer vision, deep learning, or ML systems in production
Experience building software that interfaces with hardware (IoT, embedded, kiosks, robotics)
Experience in retail, payments, or point-of-sale systems
Founding engineer or early startup experience

Responsibilities

Own 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 end.
Talk to customers. Visit kiosk deployments, sit with operators, watch transactions happen, and understand pain points firsthand â not through a requirements doc.
Design 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 kiosk.
Build simple MVPs and ship them quickly from 0 to 1. Dream up new architecture to solve challenging problems. Rethink and recreate existing codebases for scale.
Write 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 it.
Build with AI. Use LLMs, copilots, and AI development tools to move at 10x speed. Understand how to leverage AI models in production â not just as toys. You get an unlimited token budget as long as you keep shipping great work.
Solve 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 gracefully.
Support what you ship. When something breaks at a customer site, you feel it. Continuously improve and maintain code that's already in production.
