AI Engineer

vFairs is looking for an experienced AI Engineer to help us build and scale AI-powered features within our virtual events platform. Youll work at the intersection of our core product and our AI agent infrastructure designing building and shipping intelligent features that make events more engaging and easier to run for organizers and attendees alike.

Youll join a small high-leverage AI team at the center of that shift the team responsible for the agents and AI-driven tooling behind our MCP server and support experiences today and for the autonomous customer-facing agents were building next. This isnt a team bolted onto the side of the product: the agents you build will become one of the primary ways customers interact with vFairs doing in minutes what currently takes an event organizer hours of manual setup.

• Design and build fully autonomous AI agents that can independently plan sequence and execute the multi-step workflows required to build out a customers event from initial setup through configuration of sessions booths speakers and content with minimal human intervention
  

• Architect multi-agent systems using LangGraph including planner/executor patterns task decomposition sub-agent delegation and recovery logic for handling partial failures or ambiguous instructions mid-task
  

• Extend and maintain our MCP (Model Context Protocol) server as the primary interface through which these agents read and write vFairs event data defining new tools resources and permissions as agent capabilities grow
  

• Design the guardrails validation and human-in-the-loop checkpoints needed to let agents act autonomously on customer data while keeping actions safe reversible and auditable
  

• Build robust evaluation and observability pipelines for agent behavior tracking task success rate drift hallucinated actions and cost/latency and use them to drive iteration
  

• Own the full lifecycle of Agentic features: from prototyping new capabilities to hardening them for production to monitoring how they perform against real customer events
  

• Collaborate with product to translate "build my event" as a customer intent into a reliable decomposed agent workflow balancing autonomy against predictability and user trust
  

• Work with our core engineering team (primarily PHP/Laravel/Vue) to integrate agentic services into the main application including how agent actions surface and are reviewed in the UI
  

• Stay current with the fast-moving agent ecosystem (frameworks evaluation techniques autonomy patterns) and bring in whats genuinely useful skepticism of hype is as valuable as enthusiasm for new tools
  

• 6 years of professional software engineering experience
  

• Hands-on production experience building with LangGraph (or comparable agent orchestration frameworks) and FastAPI
  

• Experience designing multi-step or multi-agent systems not just single-turn chat/RAG including task planning tool orchestration and error recovery
  

• Strong Python skills with experience designing and shipping LLM-powered applications (agents RAG tool-calling structured outputs)
  

• Experience with MCP (Model Context Protocol) or similar tool/agent-to-application integration patterns
  

• Experience with vector databases (e.g. pgvector Chroma) and SQL-based retrieval strategies
  

• Solid understanding of LLM application architecture: prompt design retrieval strategies evaluation and handling model limitations/failure modes in production
  

• Judgment about autonomy: knowing when an agent should act independently versus pause for human confirmation and how to design systems accordingly
  

• Comfort working across the stack from API design to deployment and shipping features end-to-end
  

• Strong communication skills and ability to work cross-functionally with product and non-AI engineering teams
  

• Experience with PHP Laravel and our core application stack
  

• Experience with multi-cloud infrastructure
  

• Background in building customer-facing chatbots or support automation
  

• Experience with WebSocket streaming for real-time AI interactions
