Lead AI Engineer with .NET

We are seeking a Lead AI Engineer to drive the integration of AI-based features into measurement products. In this role, you will own the architecture of these features and ship them against an established AI/data platform, rather than building the platform itself. Your work will span natural-language query, summarization, intelligent validation and exception handling and workflow assistance, integrating with a model gateway, prompt registry, retrieval services and vector stores. Since outputs feed regulated measurement workflows, evaluation, auditability and human-in-the-loop patterns are central to the job, and you will be accountable for the work of a small engineering team.
Experience the freedom of remote work from anywhere in Uzbekistan, whether it's the comfort of your home or our modern office in Tashkent.
Responsibilities
Own the architecture of AI features and ship them, including natural-language query, summarization, intelligent validation and exception handling, and workflow assistance
Establish and evangelize reusable AI feature patterns for retrieval, evaluation and guardrails so teams do not reinvent them per product
Implement RAG end to end: chunking, embeddings, hybrid search, reranking, and grounded responses with citations
Drive prompt and context engineering, including multi-step and agentic flows where they add product value
Define evaluation discipline, including golden datasets, offline eval suites, LLM-as-judge approaches and per-release regression checks
Define and document complex requirements with stakeholders across product features, evaluation criteria and responsible-AI constraints
Lead and mentor a small engineering team on LLM integration and evaluation, taking accountability for their work
Manage cost, latency and reliability through caching, fallbacks, token budgets and graceful degradation
Integrate with platform services such as model gateway, prompt registry, vector stores and embedding pipelines
Apply responsible-AI practice, including tenant data isolation, auditability, OWASP LLM Top 10 mitigations and human-in-the-loop patterns
Instrument telemetry via Application Insights and Serilog
Requirements
8+ years of software engineering experience in .NET (C#) and/or Python, with lead-level ownership of AI feature architecture across one or more products
Proven background in shipping LLM-based features to production, including tool and function calling, structured outputs and streaming
Proficiency with Azure OpenAI / Azure AI Foundry, OpenAI or Anthropic APIs
Working knowledge of the component parts of a modern AI/data platform and how to build against them: model gateway, prompt registry, vector stores
Familiarity with embedding pipelines, evaluation frameworks, LLM observability and guardrails
Judgment about where AI adds product value and where deterministic logic is the better tool
Solid SQL fundamentals and API integration skills
Strong documentation and standards habits, including architecture docs in Azure DevOps Wiki, code review and testing discipline
Hands-on experience using AI coding agents in the SDLC such as GitHub Copilot, Claude or equivalent
Capability to work in agentic automation pipelines, including AI-driven PR review and QA acceptance flows triggered by ADO work item tags
English proficiency at an Upper-Intermediate level (B2) or higher
