Section 4: Total Compensation Breakdown

In AI, base salary is only part of the story. You must evaluate the Total Compensation (TC) package.

4.1 Equity Components

• RSUs (Restricted Stock Units): Common at public companies. Shares granted that vest over time (e.g., over 4 years). Their value fluctuates with the stock market. Question to ask: "What is the grant's value at today's share price?"
• Stock Options (ISOs/NSOs): Common at private companies. The right to buy shares at a fixed "strike price" in the future. Their value is the difference between the strike price and the company's future valuation. Critical question: "What is the current 409A valuation (fair market value) and the strike price?"
• How to Evaluate: For startups, understand the company's stage, funding history, and your percentage ownership. For public companies, look at the dollar value of the annual grant.

4.2 Bonuses & Incentives

• Performance Bonus: Typically 10-20% of base salary at tech companies, tied to individual and company goals.
• Sign-on Bonus: Extremely common in the competitive AI market. A one-time cash payment to offset forfeited bonuses or stock from a previous job. Can range from $25,000 to $100,000+ for senior roles.

4.3 Benefits & Perks

• Standard: High-quality health insurance, 401(k)/pension matching, life insurance.
• AI-Specific Perks: Compute budgets for personal projects, generous conference and education allowances (e.g., for courses on Coursera or DeepLearning.AI), support for open-source contributions and paper publication, and access to cutting-edge hardware (e.g., H100 GPU clusters).
