Where do you fall?

Salary trend

Estimated total: $257,000

If you are interviewing for ML Engineer roles in Charleston, here is what you are walking into. Charleston is one of the South's fastest growing tech hubs, with Boeing, Volvo, and a wave of software companies establishing operations. The city's port drives significant logistics employment. Charleston's quality of life, moderate costs, and growing tech scene attract relocating professionals from across the country. Model training expertise at scale, infrastructure optimization skills, and publication record in top venues are the strongest differentiators. ML engineers who can reduce training costs by 50% or improve model latency by an order of magnitude are exceptionally valuable. Specialization in transformer architectures, reinforcement learning, or generative models commands the highest premiums.

Entry level ML engineers (with MS/PhD) start at $130,000 to $165,000, reaching mid level at $170,000 to $220,000 in two to three years. Senior ML engineers earn $220,000 to $300,000. Staff and principal level engineers at leading AI labs can exceed $500,000 in total compensation. In Charleston, 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 labs and top tech companies often doubles total compensation, with RSU grants of $50,000 to $200,000+ annually at senior levels. Bonuses of 15 to 25% are standard. Signing bonuses of $40,000 to $100,000 are common. Compute budgets for personal research projects are a growing perk. And on the tax side: south Carolina's top income tax rate is 6.4%. Charleston has no city income tax. The state rate is moderate, and the affordable cost of living keeps net pay competitive. When someone quotes you $179,000, ask what the total package looks like. The gap between base and total comp is where real money hides.

On negotiation: Highlight the Boeing and Volvo ecosystem when negotiating. Manufacturing and engineering employers in Charleston benchmark against national aerospace pay scales. The range for ML Engineers in Charleston runs from $136,000 to $233,000. That is not a narrow window. Where you land inside it depends almost entirely on whether you negotiate and how well you prepare.
