About Mashgin

Mashgin 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 Summary

We’re looking for a backend developer to help us build the software that runs our kiosks and powers the extensive infrastructure behind them. You’ll work on our code base that enables us to develop advanced deep learning solutions that power Mashgin's checkout experience for millions on transactions per month across the world. This is not a specialized position -- we believe in end-to-end ownership of projects, so you’ll be involved throughout the entire product lifecycle, from idea generation, design, and prototyping to execution, and shipping while contributing to many different parts of the codebase in multiple languages.

What We Value:

Impact: You will own significant responsibility and have total ownership over your code. We stay lean and efficient, so your work directly impacts the product we ship every day
Simplicity: Complexity is a waste of time here—we 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 what’s possible in visual automation
Humility: 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 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 won’t 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

You Will Be

Owning major feature development and working directly with the founders on product development from end to end
Working with a small interdisciplinary team in hardware, software and design to build new versions of products from scratch
Work on building new features and dreaming up new architecture to solve challenging problems
Build backend infrastructure to perform scalable training in the cloud
Rethinking and recreating existing codebases for scale
Continuously improving and maintaining code that’s already in production

Minimum Qualifications

4+ years relevant coding experience
B.S. or higher in Computer Science (or equivalent work experience)
Excellent knowledge of one or more of these languages: Python, Node.js, C++, Go, C#, Java
Comfortable learning new languages, libraries, and frameworks when the solution calls for it
Experience building production-ready code that’s used regularly by lots of people

Preferred Qualifications

Experience in a fast-paced work environment, shipping quality code quickly and iterating
Comfortable with deploying and managing cloud infrastructure
Good knowledge of algorithms and data structures
Strong proficiency with SQL and other database technologies

What We Offer

An opportunity to work on a small, multidisciplinary team with the potential to break new ground in many different industries
Excellent health, dental and vision insurance for you and your dependents
401k plan
Flexible PTO policy
Catered lunch in office with fully stocked snacks and beverages
