  • Job Title: Senior AI Developer
  • Location: Remote — Central or South America
  • Job Type: Remote, Full-time
  • About Us: AgilityIO is a global software design and development consultancy that builds AI-driven and enterprise-grade applications for startups and Fortune 500 companies. With a distributed team of over 400 engineers, designers, and product experts across the U.S., Vietnam, and LATAM, we combine technical excellence with innovative product thinking to deliver intelligent, scalable solutions.
  • We’re seeking a Senior AI Developer to architect, build, and deploy modern AI systems and multi-agent orchestration frameworks such as LangChain, LangGraph, and CrewAI. This role is ideal for someone who thrives at the intersection of applied AI and full-stack engineering—building intelligent agents, scalable APIs, and human-in-the-loop experiences.

  • Job Responsibilities

    • Design, implement, and deploy AI systems and agentic workflows using modern orchestration frameworks (LangChain, LangGraph, CrewAI, Agno, AutoGen, or Google ADK).
    • Develop and optimize backend services and AI APIs using Python and FastAPI, integrating LLMs and Retrieval-Augmented Generation (RAG) pipelines.
    • Integrate and evaluate AI systems using Langfuse, DeepEval, or Guardrails AI to ensure performance, safety, and reliability.
    • Leverage cloud AI ecosystems such as AWS Bedrock, SageMaker, and Guardrails (or equivalent Google Vertex AI / Azure AI Foundry tools) for scalable model deployment.
    • Implement semantic search and RAG pipelines using modern embeddings (OpenAI, Cohere, etc.) and vector databases such as Qdrant, Pinecone, or Chroma.
    • Collaborate with frontend developers to integrate AI capabilities into React/TypeScript-based interfaces using frameworks like Vercel AI SDK or CopilotKit.
    • Containerize and deploy AI applications with Docker, ensuring consistent environments and CI/CD reliability.
    • Contribute to architecture decisions, code reviews, and AI system observability, ensuring robust design patterns and scalable infrastructure.
    • Stay current with the latest LLM, multi-agent, and orchestration technologies; proactively introduce new approaches for optimization and automation.

  • Qualifications & Experience

    • 5+ years of professional software development experience, with at least 1 year in AI/ML systems or LLM-based application development.
    • Strong proficiency in Python (FastAPI, asyncio, Pydantic) and hands-on experience with LangChain, LangGraph, CrewAI, Agno, or AutoGen.
    • Experience implementing LLM evaluation and observability pipelines using Langfuse, DeepEval, or Guardrails AI.
    • Proficiency with AWS AI services (Bedrock, SageMaker, Guardrails) or similar offerings in Google Vertex AI or Azure AI Foundry.
    • Familiarity with embedding-based search, RAG systems, and vector databases (Pinecone, Qdrant, Chroma).
    • Experience integrating AI-driven components into React/TypeScript frontends and deploying real-time chat or agent interfaces.
    • Knowledge of MCP, A2A, or AG-UI protocols for agent communication and data integration.
    • Strong understanding of Docker, modern DevOps workflows, and CI/CD pipelines.
    • Excellent communication and collaboration skills in English, with an ability to work cross-functionally across distributed teams.

  • Preferred Qualifications

    • Experience designing or contributing to multi-agent systems or AI copilots.
    • Familiarity with Infrastructure as Code (Terraform, CDK, or CloudFormation).
    • Contributions to open-source AI frameworks or libraries.
    • AWS certification (Solutions Architect or Machine Learning Specialty).
    • Experience with Guardrails, PII filtering, or AI safety practices.

  • What We Offer

    • Competitive salary and performance-based bonuses
    • Fully remote work flexibility across Central and South America time zones
    • Opportunity to work with a cutting-edge AI technology stack
    • Career growth and mentorship in applied AI and cloud architecture
    • Collaborative and forward-thinking engineering culture

  • Ready to Build the Future of AI?
