He found the very idea of stillness disturbing, though he often visited the observation lounge to stargaze. Despite being an engineer, Grace considered himself a warrior, and was trained in the use of the battle lance handed down to him by his forefathers, remarking that "occasionally, the old ways are still the best!"
Early in his career, Grace served on the USS Alexander and the USS Lee. He then served as chief engineer of the USS Enterprise, under both Captain Robert April and Captain Christopher Pike.
Grace continued to serve aboard the Enterprise until at least 2262, and was instrumental in rescuing Pike and Spock from captivity in the Kanes system.

By 2269, he was serving as chief engineer of the USS Lovell, and second in command of that vessel's Starfleet Corps of Engineers team
