Mashgin powers checkout automation for over 40 million users through AI-driven kiosks that ring up entire orders in under a second. The company operates over 1 billion transactions annually across professional sports venues, convenience stores, airports, universities, and more. Backed by Series B funding and already profitable, Mashgin is seeking a Hardware Validation Engineer to join their San Jose team.
In this role, you will execute comprehensive validation testing across functional, performance, stress, thermal, and reliability dimensions. You'll build and maintain hardware test setups, develop Python scripts for test automation and data collection, and troubleshoot hardware and hardware/software integration issues. Your day-to-day work includes using lab equipment (oscilloscopes, multimeters, power supplies, logic analyzers), reviewing datasheets and schematics, reproducing failures for root-cause analysis, and testing new hardware revisions and supplier samples. You'll document test procedures, results, and validation reports while maintaining hardware configuration records. As the role evolves, you'll support prototype builds, pilot deployments, and field testing, collaborating closely with hardware, software, manufacturing, and supplier teams.
Mashgin's culture emphasizes extreme ownership, autonomy, and customer obsession. The company values simplicity, hard work, humility, ruthless prioritization, and efficiency—meetings are kept short to maximize focus on real work. You'll have significant responsibility and direct impact on the product shipped daily.
