What you should know
Here is what the Principal AI Compiler Engineer market actually looks like in North Charleston. North Charleston is the industrial and manufacturing heart of the Lowcountry, home to Boeing's 787 Dreamliner assembly facility and the Charleston Naval Complex. The area has attracted significant defense, aerospace, and advanced manufacturing investment. Growth in logistics driven by the expanding port continues to drive employment. Model complexity, data pipeline scale, and infrastructure cost optimization are the primary drivers.

Signing bonuses of $25,000 to $75,000 are common when changing roles. Refresher equity grants vest annually. Relocation packages and executive benefits like financial planning are typical.

When someone quotes you $284,000, ask what the total package looks like. The gap between base and total comp is where real money hides.
