What you should know
Before you negotiate a Tool Use / Function Calling Engineer offer in Boise, understand the terrain. Boise has emerged as one of the fastest growing tech cities in the Mountain West, driven by Micron Technology, HP, and a wave of startup relocations. The city's quality of life and affordability have attracted significant in-migration from California and Washington. Tech salaries are rising fast as demand outpaces local talent supply. Compensation scales with the complexity and reliability of tool integration systems built. Engineers who can design robust function calling frameworks with error recovery and multi-step planning earn premiums. Experience with multiple LLM providers and enterprise API ecosystems drives salaries 10% to 18% above median.
Junior tool integration engineers start near $138,000 building basic function schemas. Mid-level engineers designing robust multi-tool orchestration earn $183,000 to $210,000. Principal engineers architecting enterprise tool-use platforms reach $242,000 to $290,000. In Boise, cost of living sits near the national average, so the numbers you see are roughly what you keep.
Base salary is not the full picture. Equity at AI platform companies is a significant compensation component. Performance bonuses of 12% to 18% are standard, with some roles offering developer ecosystem growth bonuses tied to platform adoption metrics. And on the tax side: idaho has a flat 5.8% state income tax. Boise has no city income tax. While higher than neighboring states, the rate is offset by affordable housing and low overall cost of living. When someone quotes you $174,000, ask what the total package looks like. The gap between base and total comp is where real money hides.

The range for Tool Use / Function Calling Engineers in Boise runs from $130,000 to $228,000. That is not a narrow window.
