Mashgin is seeking a Hardware Validation Engineer to support validation and qualification of our custom hardware platforms and checkout systems. You will work closely with senior engineers to execute validation plans, build and automate test setups, troubleshoot hardware issues, and document results.

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