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 into existing products to deliver intelligent, AI-powered experiences * 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 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 * 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 evaluation strategies covering model quality, retrieval optimization, benchmarking, and performance monitoring for deployed AI systems. * 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. ## Related Videos - [ Evaluating AI models for code comprehension](https://www.wearedevelopers.com/videos/1462-evaluating-ai-models-for-code-comprehension) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Getting to Know Your Legacy (System) with AI-Driven Software Archeology](https://www.wearedevelopers.com/videos/1437-getting-to-know-your-legacy-system-with-ai-driven-software-archeology) - [Inside the AI Revolution: How Microsoft is Empowering the World to Achieve More](https://www.wearedevelopers.com/videos/869-inside-the-ai-revolution-how-microsoft-is-empowering-the-world-to-achieve-more) - [Speak, Code, Deploy: Transforming Developer Experience with Voice Commands](https://www.wearedevelopers.com/videos/1159-speak-code-deploy-transforming-developer-experience-with-voice-commands) - [Coffee with Developers - Maria Apazoglou](https://www.wearedevelopers.com/videos/1209-coffee-with-developers-maria-apazoglou) ## Related Articles - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [Coffee with Developers - Maria Apazoglou - Making AI understandable for all in production](https://www.wearedevelopers.com/magazine/475-coffee-with-developers-maria-apazoglou-making-ai-understandable-for-all-in-production) - [Got AI ideas but no money?
