Salary trend

Estimated total: $135,000

Here is what the AI Annotation Lead market actually looks like in Charleston. 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. AI annotation leads manage labeling teams and define annotation guidelines for ML training data. Salary variance is driven by domain complexity, with medical imaging and autonomous driving annotation commanding 20 to 30% premiums over general text or image labeling. Team size and ability to maintain quality at scale also influence compensation.

Junior annotation leads start at $72,000 to $85,000. Leads managing teams of 10 to 30 annotators earn $98,000 to $132,000. Senior leads and annotation operations managers reach $138,000 to $180,000, while directors of annotation operations at large AI data companies can command $185,000 to $240,000. 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. AI startups offer equity of 0.02 to 0.1% for annotation leads. Annual bonuses range from 5 to 12%. Some companies provide project completion bonuses of $3,000 to $10,000 for delivering high-quality annotated datasets on schedule for critical model training milestones. 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 $92,000, 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 AI Annotation Leads in Charleston runs from $68,000 to $124,000. That is not a narrow window. Where you land inside it depends almost entirely on whether you negotiate and how well you prepare.
