About the role

Headquarters

We are seeking an AI Engineer to develop AI-first applications and integrate custom models and infrastructure into an existing e-commerce platform. The role focuses on building agent-led product experiences, including internal automation, dynamic site customization, and customer-facing conversational commerce workflows.

General information

This engagement supports an e-commerce startup building a platform around conversational design and intelligent automation. The current objective is to extend the existing product with AI-native capabilities while building on top of the current backend and application stack.

The work includes three core initiative areas: an internal AI employee for operational tasks, a fluid site customizer, and a customer-facing commerce agent designed to support one-prompt checkout experiences. The role will involve model integration, infrastructure setup, and product-facing implementation across both backend and UI surfaces.

Tasks and Deliverables

  • Develop AI-first applications for an existing e-commerce platform.
  • Architect and implement autonomous e-commerce AI agents using open-source and proprietary foundation models.
  • Establish GPU infrastructure and data pipelines for model fine-tuning and deployment.
  • Integrate AI workflows with the existing stack, including MongoDB, Node.js, Express, React, and third-party APIs.
  • Build conversational UI components and backend logic for one-prompt checkouts and dynamic site customization.

Required Experience

  • Strong expertise in AI/ML engineering and LLM integration.
  • Hands-on experience fine-tuning open-source models such as Llama or Mistral.
  • Experience building autonomous agents and conversational AI workflows.
  • Solid background in GPU infrastructure setup and optimization for training or inference.
  • Full-stack proficiency with MongoDB, Express, React, and Node.js.
  • Experience integrating REST APIs into production applications.
