Job summary

Appnovation is seeking an AI Builder (Agent Engineer) to join our core platform team in the Miami area. You will craft MCP servers, tools and graphs to enable agents across multiple LLMs and ensure high-quality, grounded answers.

The role emphasizes building scalable retrieval, maintaining production-grade code, and collaborating with product, data, QA in an agile environment. Strong Python and AI/LLM experience are essential.

Qualifications

• Bachelor’s Degree in Computer Science, Engineering, or equivalent practical experience.
• 5+ years of software engineering experience, with 2+ years in AI/ML or LLM-based applications.
• Strong Python, with hands-on experience in LLM application development and agentic patterns.
• Direct experience building MCP servers, tools, and skills.

• Solid software engineering fundamentals: Git, testing, and CI/CD.
• Strong problem-solving and communication skills, able to work independently in ambiguity.

Responsibilities

• Build and evolve MCP servers, tools, and skills that expose the platform to multiple LLMs (e.g., Claude, Gemini).
• Design and refine the graph-RAG pipeline that transforms documents into agent-friendly representations of facts, entities, and relationships.
• Implement retrieval across multiple tiers (source document, vector-RAG, dense graph) and temporal replay.
• Partner with QA on eval-driven improvements to answer quality and factual grounding.
• Write clean, well-tested, production-grade code and participate in code reviews.
• Collaborate closely with product, data, and QA in an agile/sprint model.
• Document designs, prompts, and tool interfaces for maintainability and handover.
• Monitor deployed agents/models, troubleshoot issues, and iterate on performance.
• Stay current with the fast-moving LLM/agent tooling landscape.
