Engineer

Engineer is Tinkaton's (aka Tinkmaster's) signature specialty. Its all-purpose hammer lets it lead the very biggest construction projects, dramatically cutting down completion time on structures that would otherwise take a long time to finish.

Hand Tinkaton some Iron Ingots and it forges Tinkagears — the mechanical parts needed for late-game builds like lifts, elevators, and moving platforms.

Because a handful of key structures (including those tied to certain Eeveelutions such as Glaceon) require Tinkagears, Engineer is one of the most impactful specialties to unlock in the late game.
