Contractor

Job Overview

We are looking for an experienced AI Engineer to design, develop, and implement production-ready AI applications and intelligent agent-based solutions.

The ideal candidate will have strong software engineering skills and hands-on experience developing LLM-powered applications, conversational AI solutions, and agentic workflows.

This role focuses on building and deploying practical AI solutions that integrate Large Language Models (LLMs), Retrieval-Augmented Generation (RAG), vector databases, and backend services to solve real-world business challenges.

Candidates should have hands-on experience with Google Agent Development Kit (ADK) and developing AI agents or chatbot applications in production environments.

Key Responsibilities

  • Design, develop, and deploy AI-powered applications using modern LLM APIs and agentic frameworks.
  • Build intelligent AI agents and multi-step workflows to support business use cases.
  • Develop and implement RAG pipelines using embeddings, vector databases, and semantic search.
  • Integrate LLM-based capabilities into existing backend applications, APIs, and microservices.
  • Develop conversational AI solutions and chatbot applications with context-aware responses.
  • Design and optimize prompts to improve response accuracy, consistency, and overall LLM performance.
  • Implement guardrails and validation mechanisms to minimize hallucinations and improve AI output quality.
  • Optimize AI applications for performance, scalability, reliability, and response latency.
  • Monitor, troubleshoot, and enhance AI solutions deployed in production environments.
  • Collaborate with product and engineering teams to deliver scalable, reliable AI solutions.

Required Skills & Qualifications

  • Strong hands-on software engineering experience developing and delivering production-grade applications.
  • Practical experience building Agentic AI applications, AI agents, or LLM-powered chatbots.
  • Hands-on experience with Google Agent Development Kit (ADK) for building agent-based applications.
  • Strong programming skills in Python or a comparable backend programming language.
  • Experience integrating LLM APIs and working with Large Language Models (LLMs).
  • Hands-on experience implementing Retrieval-Augmented Generation (RAG) architectures.
  • Knowledge of embeddings, semantic search, and vector databases such as Pinecone, Weaviate, FAISS, or similar.
  • Experience with REST APIs, microservices, and distributed application architectures.
  • Strong understanding of prompt engineering, prompt evaluation, and LLM behavior.
  • Ability to troubleshoot, optimize, and maintain AI applications in production environments.

Preferred Qualifications

  • Experience with agentic AI frameworks such as LangChain and Google ADK.
  • Exposure to multi-agent architectures and workflow-driven AI applications.
  • Experience with LLM fine-tuning, model customization, or optimization.
  • Familiarity with cloud platforms such as AWS, Google Cloud Platform, or Azure.
  • Experience working with structured and unstructured data pipelines.
  • Understanding of AI application security, reliability, and operational best practices.

Additional Requirements

  • Strong problem-solving and analytical skills.
  • Ability to work independently and collaborate effectively with cross-functional teams.
  • Comfortable working in a fast-paced engineering environment.
  • Must be willing to work in a hybrid environment in Houston, TX.
