Agentic AI Engineer: Multi-Agent Workflows & LLMs

Valiant Technologies LLC; Irvine (CA); On-site; USD 150,000 - 210,000; Full time

Job summary

Valiant Technologies LLC is seeking a skilled AI developer to design and build enterprise-grade AI agents and interoperable multi-agent workflows. You will translate business use cases into reasoning agents that maintain context, invoke approved tools and APIs, and collaborate through A2A patterns.

You will build workflows with Google ADK and Vertex AI, use Gemini models for reasoning and summarization, and develop prompts and RAG capabilities.

Qualifications

• Strong Python development skills and hands-on experience with LLM or Generative AI applications.
• Practical knowledge of agentic patterns: reasoning, orchestration, tool calling and workflow execution.
• Experience with Google ADK, Vertex AI, Agent Engine and Gemini, or comparable agent frameworks with ability to transition to this stack.
• Understanding of Agent-to-Agent (A2A) architecture and multi-agent patterns, including agent discovery, capability exchange, task lifecycle, asynchronous interactions and secure context handoff.
• Understanding of RAG, embeddings, vector search, chunking, grounding and retrieval evaluation.
• Understanding of context and memory management for conversational and multi-agent applications.
• Experience consuming REST APIs and integrating external services; familiarity with MCP for agent-to-tool connectivity.
• Working knowledge of GCP, Git/GitHub, Docker or containers, CI/CD and automated testing.

Responsibilities

• Design and build enterprise-grade AI agents and interoperable multi-agent workflows using modern agentic AI frameworks.
• Translate defined business use cases into agents that can reason, use governed enterprise knowledge, maintain context, invoke approved tools and APIs, and collaborate with other agents through A2A patterns.
• Contribute to rapid pilots and production-ready implementations using reusable platform capabilities.
• Design and develop enterprise AI agents based on defined business workflows and acceptance criteria.
• Build agent workflows using Google ADK and Vertex AI / Agent Engine.
• Use Gemini models for reasoning, planning, summarization and structured response generation.
• Develop prompts, prompt templates and structured outputs; support prompt testing and evaluation.
• Implement RAG capabilities using approved enterprise knowledge sources, chunking, embeddings and retrieval.
• Implement session context, short-term memory and long-term memory patterns where required.
• Integrate agents with approved MCP tools, REST APIs and external AI services.
• Design agent-to-agent collaboration using A2A patterns, including agent discovery, capability definition, task delegation, context exchange, status handling and response coordination.
• Implement orchestration, tool selection, multi-step execution and human-in-the-loop checkpoints across single-agent and multi-agent workflows.
