About Mashgin
Mashgin powers the worlds 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.
Mashgins technology powers over 1 billion transactions at your favorite locations including over half of all US professional sports teams 4000 convenience stores major airports universities and more.
Were not just building cutting-edge AIwere creating real-world impact and unforgettable experiences. Backed by a well-funded Series B were also one of the rare AI startups thats already profitable.
Our secret A culture of extreme ownership autonomy and customer obsession. At Mashgin we are building something extraordinary by challenging conventional wisdom. Weve thrown out the old rules to focus on what truly matters: creating a kickass product that makes people say Wow. We dont 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 youre in the right place.
Position Summary
This is not a specialized position. Were hiring Builders people who can wear every hat and ship products that blow peoples 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 dont 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 its right.
Youll 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. Youll use AI tools to move at 10x speed but youll understand whats happening under the hood.
If you could credibly start a company tomorrow and do every job yourself engineering design product support youre the kind of person were 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. Youll 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 day.
- Simplicity: Complexity is a waste of time herewe take pride in building things that just work.
- Hard 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 whats possible in visual automation.
- Humility: No task is beneath you. Whether its high-level architecture or grunt work to fix a bug we check our egos at the door and get real work done.
- Ruthless 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 improvements.
- Customer Innovation: We are customer-centric not customer-pleasing. You wont bend to every client demand; you will let innovation drive the product forward to solve the real problems our users face.
- Efficiency: Meetings suck. We keep them short and only use them for alignment giving you your time back to focus on real work.
What Youll Do
- Own products not tickets. Take a problem from we heard this from customers to its live in 4000 locations. You decide what to build how to build it and when to ship. Youll 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 not through a requirements doc.
- Design the experience. Sketch UIs prototype interactions and make product decisions. You dont 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 dont 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 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 thats already in production.
Who You Are
- Youre a builder at heart. Youd be building software even if nobody paid you. You have side projects open source contributions or a startup in your past (or future).
- Youre deeply technical. 5 years shipping production software. Excellent knowledge of one or more of: Python C Go C# Java. Experience building production-ready code thats used regularly by lots of people.
- You think like a product person. You dont 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 matters.
- You move fast. You bias toward action. Ship MVPs get feedback iterate. Youd rather have something in front of users in a week than a perfect spec in a month.
- Youre comfortable with ambiguity. We wont hand you a fully-specced PRD. Youll figure out what the right thing to build is often with incomplete information.
- You use AI as a multiplier. Youre fluent with AI-assisted development tools and understand how to use LLMs to accelerate your workflow 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 engineering design product customer support youre the kind of person were looking for.
