Description:

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

• AI tools and applications used across multiple internal departments (engineering, operations, support, product, tax, compliance, and more) 

• Customer-facing AI capabilities embedded in our existing products 

• The creation of entirely new AI-native products that leverage AI as a foundational capability 

​

This is a senior, hands-on technical role for an engineer 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 will act as both a technical leader and a multiplier—shaping architecture, setting standards, and enabling teams across the company to build effectively with AI. 

RESPONSIBILITIES:

AI Platforms & Internal Enablement 

• 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). 

• Develop internal AI platforms, shared services, and reusable components that enable teams to safely and effectively build AI-powered applications. 

• Build and maintain retrieval-augmented generation (RAG) systems grounded in internal documentation, codebases, tax knowledge, and proprietary data. 

• Partner with DevOps, platform, and security teams to ensure AI systems are scalable, observable, secure, and compliant. 

Customer-Facing AI & AI-Native Products 

• Embed AI capabilities into existing Taxwell products to improve accuracy, usability, personalization, and customer outcomes. 

• Architect and build new customer-facing products where AI is a core differentiator, not an add-on. 

• Work closely with product, design, and tax domain experts to translate real user problems into effective AI powered solutions. 

• Ensure AI features meet high standards for reliability, explainability, and trust—especially in a regulated domain like tax. 

Technical Leadership & Strategy 

• Design and implement agent-based systems using frameworks such as LangChain, LangGraph, ADK, or similar. 

• Evaluate and integrate commercial and open-source AI technologies, including frontier models and open-weight LLMs. 

• Establish best practices for prompt engineering, evaluation, monitoring, and continuous improvement of AI systems. 

• Influence AI architecture and technical direction across the organization through design review and hands-on collaboration. 

• Measure system effectiveness using telemetry, automated metrics, and qualitative feedback from internal and external users. 

REQUIRED QUALIFICATIOS:

• 10+ years of software engineering experience, including 3+ years' operating at a Principal- or Staff-level role. 

• Proven experience designing and deploying production AI systems used by real users. 

• Strong hands-on experience with LLM-enabled systems, including prompt engineering, RAG, and agent orchestration. 

• Proficiency in Python and/or TypeScript. 

• Experience integrating AI systems with real-world applications, workflows, and data sources. 

• Familiarity with vector databases and embedding techniques (e.g., Pinecone, FAISS, Chroma). 

• Experience deploying and operating systems on AWS, GCP, or Azure. 

• Strong architectural judgment and the ability to balance experimentation with production rigor. 

PREFERRED QUALIFICATIONS:

• Experience building AI platforms or internal copilots used across multiple teams or departments. 

• Experience developing customer-facing AI products at scale. 

• Background in regulated industries such as fintech, tax, or healthcare. 

• Experience fine-tuning or customizing open-weight models (e.g.,GPT-OSS-120B, Mistral 3, GLM-4.7).
