AI Agent Product Engineer / AI Agent Developer

We are looking for an experienced AI Agent Product Engineer to help us build production-ready AI agents that can be used directly by businesses and the general public. We are not looking for someone who only builds prototypes, automations or basic chatbot demos. We need someone who has experience turning AI agents into reliable, scalable products with real users. You will work on AI products for Servicia, including Agents on Demand and Companies on Demand, as well as AI agents that may be offered to external clients through our AI initiatives. The ideal candidate has experience with: OpenAI API and agentic AI frameworks OpenAI Agents SDK, LangGraph or similar technologies Tool calling and multi-agent workflows RAG and knowledge bases Memory and context management API integrations Authentication and user management Multi-tenant SaaS applications Human-in-the-loop approvals Guardrails and permissions Monitoring, logs and observability AI evaluations and reliability testing Managing token and inference costs Payments and subscriptions Deploying AI products to real users Full-stack development Experience with voice agents, WhatsApp, Gmail, Google Drive, CRM, ERP or enterprise software integrations is a strong plus. We are particularly interested in developers who have already launched AI agents or AI-powered SaaS products used by real customers. This can begin as a freelance project, with the possibility of becoming a long-term relationship. We expect to develop multiple agents and eventually create a reusable platform that allows us to rapidly build, customize, deploy and monetize AI agents.
