• 6+ years of professional software engineering experience.
• Hands-on experience with LangGraph and FastAPI.
• Experience designing multi-step or multi-agent systems with planning and recovery.
• Strong Python skills and building LLm-powered applications.
• Experience with MCP or similar tool-application integration patterns.
• Familiarity with vector databases (pgvector, Chroma) and SQL-based retrieval.
• Understanding of LLM app architecture and production failure modes.
• Ability to balance autonomy with human confirmation and ship end-to-end features.
• Strong cross-functional collaboration with product and non-AI teams.

Responsibilities

• Design and build fully autonomous AI agents to plan, sequence, and execute multi-step workflows.
• Architect multi-agent systems using LangGraph with planner/executor patterns.
• Extend and maintain MCP server as primary interface for event data.
• Design guardrails, validation, and human-in-the-loop checkpoints.
• Build evaluation and observability pipelines for agent behavior.
• Own lifecycle of Agentic features from prototyping to production.
• Collaborate with product to translate customer intents into decomposed agent workflows.
• Work with core engineering (PHP/Laravel/Vue) to integrate services into the main app.
• Stay current with agent ecosystem and assess useful frameworks.

Job description

vFairs is an all-in-one event management platform and Gartner Magic Quadrant Leader helping event planners power conferences, trade shows, and corporate events with in-person, hybrid, and virtual solutions. Our platform includes event registration, on-site badge printing, mobile apps, and more, managing the entire event lifecycle from planning through analytics. Rated 4.9/5 for customer support and recognized as a top platform on G2, we're known for robust technology and customer service that goes the extra mile. vFairs has a transparent, fast-paced, and collaborative culture, with geographically distributed teams united by strong processes and the autonomy to drive solutions forward.

Job Description

About the Role

vFairs is looking for an experienced AI Engineer to help us build and scale AI-powered features within our virtual events platform. You'll 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.

You’ll 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 we're building next. This isn't 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.

What You'll Do

Design and build fully autonomous AI agents that can independently plan, sequence, and execute the multi-step workflows required to build out a customer's 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 what's genuinely useful — skepticism of hype is as valuable as enthusiasm for new tools

What We're Looking For

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

Nice to Have

Experience with PHP, Laravel, and Vue.js — 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
