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 are looking for a developer-centric AI Engineer to join us in revolutionizing how we build software. You will be responsible for building the "engine that drives the engineers." By leveraging Large Language Models (LLMs) and intelligent automation, your goal is to make our engineering team 10x more productive.

This is not a traditional "research" role. This is a highly technical, hands-on, execution-oriented position where you will build production-grade tools that integrate directly into our development and production lifecycle—from automated code reviews, intelligent documentation, and context-aware debugging.

We maintain a flat, high-impact engineering culture where every engineer who joins our team carries the title of Member of Technical Staff.

For roles based in Palo Alto, CA, the overall market range for Mashgin is typically $185,000 - $275,000 USD annually. Note that total compensation for this position will be determined by candidate’s relevant qualifications, work experience, skills, and other relevant factors. This estimate excludes the value of any benefits offered by Mashgin, and the potential future value of any other long-term incentives.

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 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 Developer Productivity: Identifying bottlenecks in the Mashgin engineering workflow and architecting LLM-powered solutions to eliminate them.

Interviewing engineers to understand their current process and accelerating them 10x.

Building Intelligent Tooling: Implementing 0-to-1 systems for automated code refactoring, test generation, and context-aware documentation.

Bridging Infrastructure and AI: Architecting and deploying LLM-powered services using both commercial APIs (like Claude) and open-source models.

Scaling Workflows: Rethinking and recreating existing internal CI/CD and build processes to integrate AI-driven bug detection and security vulnerability assessments.

Prototyping & Shipping: Building simple MVPs of developer tools and shipping them quickly to the team for immediate feedback and iteration.

Minimum Qualifications

6+ 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 with LSPs (Language Server Protocols) and IDE integration

Experience managing and optimizing large monolithic repositories, including build systems and version control workflows

Strong proficiency with SQL and database technologies

Knowledge of cloud infrastructure (AWS, Terraform, or similar)

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
