Signing bonuses of $40,000 to $100,000 are common given the extreme demand. Benefits include dedicated GPU access, research time allocations, and conference travel budgets. And on the tax side: tennessee has no state income tax on wages. Knoxville has no city income tax. This zero income tax environment combined with very affordable housing creates excellent purchasing power. When someone quotes you $169,000, ask what the total package looks like. The gap between base and total comp is where real money hides.
