Posted 3 weeks ago

Worldwide

Summary

We're looking for a versatile engineer who builds production-grade web applications and architects intelligent, autonomous AI systems. You'll work across the full stack, designing responsive frontends, robust backend APIs, and databases while integrating LLMs and deploying agentic AI workflows that solve real business problems. You'll own the end-to-end delivery of AI-powered features: from prompt engineering and RAG pipelines to multi-agent orchestration using frameworks like LangChain, LangGraph, or AutoGen. This role sits at the intersection of solid software engineering and cutting-edge AI, ideal for someone equally comfortable shipping user-facing products and reasoning about agent reliability and performance at scale. *What you'll bring:* 3–6 years of full-stack experience, hands-on LLM API integration, and familiarity with agentic patterns, tool calling, memory systems, and multi-step reasoning. Cloud deployment, CI/CD, and a curiosity for what's next in AI are a must.
