We are looking for an AI Engineer to help build and scale our next-generation AI platform, with a strong focus on agentic systems. In this role, you’ll design and develop intelligent agents powered by LLMs—leveraging tool calling, orchestration frameworks, and advanced context management to enable reasoning, planning, and autonomous decision-making across complex workflows. You’ll work hands-on with modern agentic stacks (e.g., LangGraph, Autogen), asynchronous and streaming architectures, and production-grade observability to bring scalable, real-world AI systems to life. If you’re passionate about pushing the boundaries of agentic AI and building systems that operate reliably in production, AppZen offers a high-impact environment to do just that.
We are an equal opportunity employer and value diversity. All employment is decided on the basis of qualifications, merit and business need.
