About the Role

We are seeking a Principal AI Data Scientist to lead the design, development, and deployment of AI-powered systems across Taxwell. These systems include:

\n
• AI tools and applications used across multiple internal departments (engineering, operations, support, product, tax, compliance, and more)
\n
• Customer-facing AI capabilities embedded into existing products to deliver intelligent, AI-powered experiences
\n
• Design and development of vertical AI solutions for the tax and compliance industry, as well as AI-native products built with generative AI at their core
\n

This is a senior, hands-on technical role for a Data Scientist who has operated at the Principal level and has a strong track record of turning emerging AI capabilities into production-grade systems with real business impact. You’ll apply technical expertise across AI evaluation, retrieval optimization, memory and state management, and AI agent architecture to support real-time insights and decision-making.

Responsibilities

AI Platforms & Internal Enablement

\n
• Design and build AI-powered tools that improve productivity across engineering and non-engineering teams (e.g., developer workflows, customer support tooling, tax development, operations, compliance, and analytics).
\n
• Develop evaluation strategies covering model quality, retrieval optimization, benchmarking, and performance monitoring for deployed AI systems.
\n
• Develop internal AI platforms, shared services, and reusable components that enable teams to safely and effectively build AI-powered applications.
\n
• Build and maintain retrieval-augmented generation (RAG) systems grounded in internal documentation, codebases, tax knowledge, and proprietary data.
\n
• Partner with DevOps, platform, and security teams to ensure AI systems are scalable, observable, secure, and compliant.
\n

Customer-Facing AI & AI-Native Products

\n
• Embed AI capabilities into existing Taxwell products to improve accuracy, usability, personalization, and customer outcomes.
\n
• Architect and build new customer-facing products where AI is a core differentiator, not an add-on.
\n
• Work closely with product, design, and tax domain experts to translate real user problems into effective AI powered solutions.
\n
• Ensure AI features meet high standards for reliability, explainability, and trust—especially in a regulated domain like tax.
\n

Technical Leadership & Strategy

\n
• Design and implement agent-based systems using frameworks such as LangChain, LangGraph, ADK, or similar.
\n
• Evaluate and integrate commercial and open-source AI technologies, including frontier models and open-weight LLMs.
\n
• Establish best practices for prompt engineering, evaluation, monitoring, and continuous improvement of AI systems.
\n
• Influence AI architecture and technical direction across the organization through design review and hands-on collaboration.
\n
• Measure system effectiveness using telemetry, automated metrics, and qualitative feedback from internal and external users.
\n

Qualifications

\n
• 8+ years of Data Science experience, including 3+ years' operating at a Principal or Staff-level role.
\n
• 5+ years of experience with Generative AI, LLMs, AI agents, or RAG applications, and designing, developing, and deploying AI solutions.
\n
• 3+ years of experience with AI agents and AI evaluation strategies in enterprise environments.
\n
• Proficiency in Python and/or TypeScript.
\n
• Experience integrating AI systems with real-world applications, workflows, and data sources.
\n
• Familiarity with vector databases and embedding techniques (e.g., Pinecone, FAISS, Chroma).
\n
• Experience deploying and operating systems on AWS, GCP, Azure, Databricks, or Snowflakes.
\n
• Strong architectural judgment and the ability to balance experimentation with production rigor.
\n

Preferred Skills

\n
• Experience building AI platforms or internal copilots used across multiple teams or departments.
\n
• Experience developing customer-facing AI products at scale.
\n
• Background in regulated industries such as fintech, tax, or healthcare.
\n
• Experience fine-tuning or customizing open-weight models (e.g., GPT-OSS-120B, Mistral 3, GLM-4.7).
\n
