For most IT roles, Phoenix employers pay a little less than the national median. Software developers earn a median $131,750 against $135,980, systems administrators $93,730 against $99,130, and data scientists $114,540 against $120,230. That works when you hire locally. It works less well when the candidate also holds a remote offer priced on a national band, which is common for software and data roles. Check the software engineer and systems administrator Salary Guide pages before you set a range.
The practical read: entry-level support and operations roles are relatively easy to fill in Phoenix, mid-level software roles are competitive on pay, and security, database and data-science searches often need candidates from outside the metro or a stronger offer. Contract-to-hire is a good fit for data center operations and service desk leads, where you want to see someone on shift before converting.
