Where do you fall?

Salary trend

Estimated total: $170,000

Before you negotiate a AI Documentation Engineer offer in Charleston, understand the terrain. 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. Compensation reflects the ability to create comprehensive documentation for AI systems including model cards, data sheets, system design docs, and user-facing AI explanations. Engineers who can document complex ML architectures with both technical accuracy and accessibility command premiums. Experience with AI governance documentation requirements adds value.

Junior documentation engineers start at $75,000 to $90,000. Mid-level engineers producing model cards and system docs reach $108,000 to $135,000. Senior engineers leading AI documentation programs earn $140,000 to $170,000. Directors of AI documentation at large companies can reach $180,000 to $220,000 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 companies adds $10,000 to $40,000 annually. Bonuses of 8% to 12% are standard. Benefits often include learning stipends for maintaining AI technical knowledge, conference attendance budgets, and access to documentation tooling platforms. Remote work flexibility is common. 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 $114,000, 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 Documentation Engineers in Charleston runs from $84,000 to $146,000. That is not a narrow window. Where you land inside it depends almost entirely on whether you negotiate and how well you prepare.
