We thrive in a global, inclusive culture that values innovation, collaboration, and technical excellence. With continued growth, we’re looking for a **Principal AI Engineer **to join our **HotDocs Team**. HotDocs is Mitratech’s flagship document automation platform, used by enterprise clients worldwide to streamline the assembly of complex legal documents and contracts. ### **You'll set the technical direction for AI at HotDocs - designing and delivering new AI-powered enterprise capabilities and driving our adoption of AI across the software development lifecycle. This is a remote-first role.**   ### **About the Role** As a Principal AI Engineer, you will: -       **Set the AI Technical Direction: **Own the architecture for AI capabilities across HotDocs - model management, LLM and agent orchestration, retrieval strategy, evaluation, cost and latency management - and translate it into a pragmatic delivery roadmap. -       **Deliver Enterprise AI Features: **Take new AI-powered features from prototype to production at enterprise scale, writing clean, maintainable code in .NET Core and React and holding the bar for performance, security, and readability. -       **Drive AI Adoption in the SDLC: **Lead how we use AI across engineering - coding assistants, agentic workflows, test generation, code review, and documentation - selecting tooling, defining safe and effective usage patterns, and measuring the impact on delivery. -       **Build Trustworthy AI: **Establish evaluation harnesses, guardrails, observability, and AI governance practices so that AI features are accurate, explainable, and safe for use in regulated, compliance-heavy environments. -       **Bring Deep Technical Expertise: **Apply strong .NET and React ecosystem knowledge to complex problems, modernize and refactor legacy code where it blocks AI integration, and improve system scalability and reliability. -       **Lead and Mentor: **Raise the AI capability of the wider engineering group through code reviews, design reviews, pairing, brown-bag sessions, and clear written guidance. -       **Influence Across the Business: **Partner with product management, architecture, security, and customer-facing teams to shape the AI roadmap, evaluate build-versus-buy decisions, and set realistic expectations for what AI can deliver. -       **Enhance DevOps and AI Ops: **Extend CI/CD pipelines to cover AI workloads - prompt and model versioning, automated evaluation gates, monitoring, and cost tracking - working closely with DevOps engineers. -       **Focus on the User:** Ensure AI features solve real customer problems and deliver a great experience through attention to detail, responsiveness, transparency, and accessibility.   ### **About You** You are: -       **A Technical Leader: **You set direction without needing authority, build consensus across teams, and communicate clearly with technical and non-technical peers. -       **An AI Practitioner, not a Spectator: **You have shipped AI features to real users, keep pace with a fast-moving field, and can tell genuine capability from hype. -       **Evidence-Led:** You care about maintainable code, testing, and measurable outcomes - you evaluate AI systems with data rather than intuition. -       **Adaptable and Pragmatic:** You balance long-term architectural goals with the practical needs of a sprint-driven environment, and you know when a simple solution beats a model. -       **Security-, Privacy- and Performance-Minded**: You build with scalability and resilience in mind, using secure-by-design principles, and you treat data privacy and responsible AI as first-order concerns.   ### **Required Skills and Experience** -       12 or more years of professional software development experience, including time in a principal, lead, or staff-level technical role. -       Strong skills in **.NET Core (C#)** and **React (TypeScript)** or similar SPA frameworks - this remains a hands-on engineering role. -       Demonstrable experience designing and shipping production **AI solutions** - LLM integration, prompt engineering, RAG, MCP, and agentic or tool-calling systems. -       Hands-on experience with cloud AI platforms and services (e.g. Azure OpenAI / AI Foundry, or equivalent) and with orchestration frameworks such as Semantic Kernel. -       Experience building and maintaining **REST APIs**. -       Proficiency with **Entity Framework** and **Azure SQL** (or SQL Server). -       Experience evaluating and improving AI system quality - test sets, benchmarking, human review loops, and handling non-deterministic behavior. -       Understanding of **web applications **and AI-specific security, including secure coding, prompt injection, and safe handling of sensitive customer data. -       Experience using **Git** and collaborating through modern workflows (e.g., pull requests, branching strategies). -       Experience with CI/CD pipelines (Azure DevOps or similar). -       Comfortable working in agile teams using tools such as Jira and Confluence. -       Practical experience using AI tooling within the SDLC (e.g. coding assistants, agentic developer tools) and a view on how to adopt it well across a team. -       A track record of technical leadership - mentoring senior engineers, leading design reviews, and influencing roadmap and architecture decisions.   ### **Nice to Have** -       Deeper AI specialism in areas such as SLMs and fine-tuning, CAG, vector databases, AI observability, multi-agent systems, or AI/ML pipelines. -       Experience with Microsoft Office Addins (office.js / VSTO) -       Familiarity of .NET Framework / WPF -       Experience with authentication standards such as **OAuth** and **SSO**. -       Exposure to **distributed caching** (e.g., Redis) -       Knowledge of **Linux environments** and **containerization** (Docker). -       Scripting in **PowerShell**. -       Familiarity with **performance tuning** and application diagnostics. -       Experience with **infrastructure-as-code** or automation tooling. -       Previous experience in enterprise SaaS or compliance-heavy domains (e.g., legaltech, fintech), particularly applying AI to document, contract, or natural language workloads.   ### **What We Offer** -       A collaborative, supportive, and learning-focused work culture. -       The chance to shape an AI strategy end to end, from architecture through to production, at enterprise scale. -       Opportunities to grow your technical skills and career path. -
