About this role

Senior GenAI Engineer

  • The vacancy has been successfully added to favorites
  • We are seeking a hands-on GenAI Engineer to join a team developing production-grade, AI-powered solutions for a major US insurance provider.
  • Designed and developed an enterprise-grade Generative AI platform using Python, FastAPI, and FastMCP to automate recruitment workflows and provide intelligent candidate insights. Built scalable, production-ready APIs that integrated with OpenAI GPT and Anthropic Claude models for candidate screening, resume analysis, job matching, and automated recruiter assistance.
  • Implemented RAG (Retrieval-Augmented Generation) pipelines using vector databases such as Pinecone/Milvus to provide context-aware responses from enterprise knowledge repositories. Developed AI Agents and custom plugins/skills to automate candidate engagement, interview scheduling, talent recommendations, and workflow orchestration.
  • Owned the complete application lifecycle, including architecture design, API development, deployment, monitoring, observability, logging, and performance optimization. Leveraged AI-assisted development tools such as Claude, Codex, and VS Code to accelerate development, debugging, code reviews, and delivery.

Responsibilities

  • Design and deliver production-grade GenAI solutions using OpenAI GPT and Anthropic Claude models.
  • Build agentic workflows using LLM orchestration frameworks such as LangChain, LangGraph or similar, including multi-step reasoning, tool use and human-in-the-loop patterns.
  • Design and implement RAG pipelines covering document ingestion, chunking, embeddings, hybrid search, re-ranking and retrieval quality tuning.
  • Develop MCP servers using FastMCP to expose enterprise tools and data to AI agents.
  • Create and extend Skills and Plugins that adapt LLM capabilities to insurance-specific workflows.
  • Work with vector databases to support semantic search and knowledge retrieval.
  • Implement LLM evaluation, guardrails and safety controls, including hallucination detection, prompt injection protection and PII handling.
  • Implement observability and diagnostics for LLM systems: tracing, evaluations, token and cost tracking, latency and quality monitoring.
  • Build scalable backend APIs in Python and FastAPI that serve GenAI capabilities to client applications.
  • Own the full lifecycle of GenAI applications: prototyping, development, deployment, monitoring and continuous improvement.
  • Use AI-assisted development tools (Claude, Codex) as a core part of the daily engineering workflow.
  • Advise client stakeholders on GenAI feasibility, solution design, cost and model selection.

Skills

Must have

  • GenAI experience (primary focus):
  • 2+ years of hands-on GenAI engineering experience, with at least one LLM-based solution delivered to production.
  • Deep practical experience integrating OpenAI GPT and Anthropic Claude: prompt engineering, tool/function calling, structured outputs, streaming and context management.
  • Proven experience designing, building and tuning RAG pipelines in real-world projects.
  • Hands-on experience building agentic solutions with LangChain, LangGraph, LlamaIndex or similar frameworks.
  • Practical experience with MCP servers (FastMCP preferred) and LLM extension mechanisms such as Skills and Plugins.
  • Hands-on experience with at least one vector database (e.g., Pinecone, Weaviate, Qdrant, Chroma, pgvector, Azure AI Search).
  • Experience with LLM observability and evaluation tooling (e.g., LangSmith, Langfuse, Arize Phoenix, OpenTelemetry).
  • Understanding of LLM limitations and risks: hallucinations, prompt injection, cost and latency trade-offs, and model selection.
  • Engineering:
  • 4+ years of professional software development experience with a strong focus on Python.
  • Solid experience building production REST APIs with FastAPI.
  • Experience deploying and running applications in production: Docker, CI/CD and at least one major cloud platform (AWS, Azure or GCP).
  • Daily, confident use of VS Code and AI coding assistants such as Claude and Codex.
  • Upper-Intermediate (B2) or higher English, with the ability to communicate directly with US-based stakeholders.

Nice to have

  • Experience applying GenAI in insurance or financial services (e.g., claims automation, document understanding, underwriting assistance).
  • Experience with fine-tuning, embeddings optimization or open-source LLMs.
  • Experience with multi-agent architectures and agent-to-agent communication.
  • Kubernetes and infrastructure-as-code (Terraform, Bicep).
  • Knowledge of responsible AI practices and compliance requirements for PII in regulated industries.
