Accountabilities:

  • Design and implement autonomous agents and multi-agent orchestration systems capable of handling complex, open-ended tasks.

  • Build and optimize production-grade applications on top of leading foundation models, with a focus on reliability, observability, scalability, and low-latency performance.

  • Architect advanced Retrieval-Augmented Generation (RAG) pipelines and vector database strategies that provide agents with accurate, relevant, and real-time context.

  • Develop sophisticated tool-calling, planning, reasoning, and autonomous execution workflows for AI agents.

  • Contribute to AI-powered developer tools and internal frameworks that accelerate the development and deployment of AI-native products.

  • Establish rigorous evaluation frameworks and Evals to measure model and agent performance in production environments.

  • Implement monitoring, fine-tuning, testing, and optimization pipelines to improve accuracy, reliability, and safety.

  • Collaborate across product and engineering functions to integrate foundation models into solutions that address real-world user needs.

  • Help shape the technical architecture and engineering practices for scalable AI-native systems.

  • Continuously evaluate emerging AI technologies, frameworks, and approaches and identify opportunities to incorporate them into production systems.

Requirements


  • Proven experience building production applications using large language models, AI agents, or other advanced AI technologies, ideally within an AI-native startup, research environment, or developer-tool organization.

  • Deep understanding of agentic systems, including agent frameworks, tool calling/function calling, autonomous planning, and reasoning loops.

  • Expert-level proficiency in Python and/or TypeScript with Node.js.

  • Hands-on experience with LangChain, LlamaIndex, or custom-built AI orchestration frameworks.

  • Strong expertise with vector databases such as Pinecone, Weaviate, or Milvus.

  • Experience designing efficient machine learning and data pipelines.

  • Strong understanding of foundation model applications and the practical challenges of deploying LLM-powered systems at scale.

  • Experience building sophisticated RAG architectures and retrieval strategies.

  • Strong product intuition and the ability to translate emerging AI capabilities into useful, reliable products rather than purely academic experiments.

  • Experience with production AI engineering practices, including evaluation, monitoring, optimization, and reliability.

  • Ability to work effectively in a distributed, global-first environment with a high degree of autonomy and ownership.

  • Strong problem-solving skills and a willingness to work on complex, ambiguous technical challenges.
Benefits:
  • Fully remote opportunity with a global-first distributed team.

  • Primary hiring regions include the United States, Europe, and India.

  • Opportunity to work directly on autonomous agents, LLM applications, advanced RAG, and AI-native product infrastructure.

  • Exposure to leading foundation models and modern AI development frameworks.

  • Significant technical ownership at the intersection of product engineering and frontier AI research.

  • Opportunity to build production-grade AI systems rather than experimental prototypes.

  • For US-based candidates, a 3-month contractor-to-hire period followed by potential conversion to full-time employment.

  • For candidates outside the US, long-term independent contractor engagement through OnTop.

  • Opportunity to contribute to AI-powered developer tools and emerging AI technologies.

  • Potential for significant career growth in a rapidly evolving AI environment.
