Full Job Description

đź“‹ Description

  • • We are looking for a Full Stack Engineer - AI Systems to build the product layer that turns AI capabilities into usable, production-grade workflows.
  • • The role involves designing how agents operate, fail, recover, and deliver consistent value to users.
  • • Key responsibilities include building end-to-end product features across frontend, backend, and AI integrations, designing agent workflows that handle planning, tool use, failure, and recovery across multiple steps, and integrating LLMs, memory, and external tools into systems that behave reliably under real-world conditions.
  • • The ideal candidate will have strong experience in full stack engineering, solid understanding of system design and API architecture, experience working with LLMs, RAG systems, or AI-powered applications, and ability to handle ambiguity and make pragmatic engineering decisions.
  • • The role requires strong ownership, ability to take features from idea to production, and comfort working in fast-moving environments with evolving requirements.
  • • The successful candidate will own and ship AI-native product features that move beyond chat into persistent, goal-driven workflows, design and deploy agent workflows that reliably complete multi-step tasks across tools and sessions, reduce latency and improve responsiveness of AI interactions while maintaining output quality, and build robust fallback and recovery mechanisms for LLM and tool failures in production environments.
  • • The team uses a tech stack including Next.js, Python, NodeJs, Pytorch, OpenAI / Anthropic / open-source LLMs, SQL & noSQL, Kubernetes, and Docker.
  • • The company values transparency and efficiency, and expects a prompt decision.
