Senior🎓
Top SchoolGreg Kaiser is a Senior Staff Software Engineer with 20+ years of systems and embedded software experience and a decade focused on Android, currently helping scale Android Go to 250+ million users. He specializes in C/C++ system-level engineering—firmware, low-power sensor domains (CHRE), real-time avionics, and build/release automation—bringing deep expertise in memory/time-constrained environments. At Google he authored foundational CHRE APIs and drove stability in critical Android subsystems; his open-source contributions span high-profile projects like Skia and multiple AOSP components where he fixes subtle correctness and build issues. Greg pairs hands-on bug-fixing and tooling work with architectural thinking, having led system design on surgical-robot software and real-time flight systems. Based in Louisville, Colorado, he enjoys improving long-lived infrastructure and build systems—often via small, high-impact fixes that prevent elusive runtime failures.
