Senior🎓
Top SchoolPhillip Dunlap is a Principal Verification Engineer with 12 years of hands-on experience building and debugging embedded systems, internal tooling, and server-side software from Longmont, Colorado. He began contributing to production platforms early at Infinite Automation, becoming a go-to engineer for Mango Automation product and protocol integrations, UI work, and client training. Phillip pairs low-level verification expertise—having tested ARM ASIMD blocks—with backend Java development, notably contributing bug fixes and new data types to the popular modbus4j Modbus library. As a frontline problem-solver he prototypes simulators and tooling, handles complex debugging requests, and drives extensions that make systems more observable and reliable. Colleagues rely on his practical mix of engineering breadth and persistence; he also brings a playful, unconventional curiosity that fuels creative approaches to tricky problems.
