Position Summary

We’re looking for a full-stack developer to help us build the software that runs our kiosks and powers the extensive infrastructure behind them. In addition to building more traditional web stacks, you’ll work on code that interfaces with our hardware and visual components, making sure kiosks are extra reliable and the user experience amazing. 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.

This is a remote, contract position for individuals who are based in Curitiba, Brazil. Mashgin is headquartered in Palo Alto, CA. We maintain a flat, high-impact engineering culture where every engineer who joins our team carries the title of Member of Technical Staff.

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.
