Position Summary

Mashgin is seeking a Mechanical Product Design Engineer to join our hardware engineering team. You’ll play a key role in developing the next generation of Mashgin kiosks, working from concept to mass production in a fast-paced, cross-functional environment.

This is a hybrid role that requires you to be onsite at least 2 days a week in San Jose, CA.

• 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.
