Senior State and Local Income Tax Researcher

What You'll Do

What Your Responsibilities Will Be

• Train and refine Avalara’s AI on authoritative state and local income tax materials (statutes, regulations, case law) to answer complex customer questions accurately.
• Build and own a world-class state and local income tax research product, defining quality standards and the roadmap for AI agents like Avi.
• Curate and structure authoritative source materials for AI agents to reason through scenarios like audit defense, corporate structuring, apportionment, and transfer pricing.
• Develop reusable prompt libraries, validation frameworks, and rigorous quality-review standards for tax-specific AI applications.
• Establish measurable quality benchmarks and controls confirming AI answers trace back to primary legal sources.
• Review AI agent outputs against primary legal sources to ensure defensibility and compliance integrity.
• Identify high-impact AI opportunities to improve research speed, scale, and quality.
• Raise the AI fluency of peers by sharing frameworks, governance practices, and structured research methods.

• Hands-on experience applying AI tools: designing effective prompts, building validation frameworks, or creating structured AI workflows with measurable results.
• A genuine passion for raising the bar on how AI is used to capture and apply tax knowledge.
• Preferred: Advanced degree (J.D., LL.M. in Taxation, or M.S. in Taxation).
• Preferred: Experience with knowledge management systems, structured data formats (e.g., JSON, XML), or legal research platforms.
• Preferred: Familiarity with large language model (LLM) behavior, retrieval-augmented generation (RAG), or AI agent architectures.
