You will be at the heart of designing and building agentic systems that automate and revolutionize how designers and brands manage their supply chain, inventory, and digital storefronts.

  • Develop intuitive and powerful frontend interfaces using SvelteKit that allow brands to effortlessly manage their presence on Carrousel.
  • Collaborate with our AI/ML team to integrate cutting-edge models into user-facing products.
  • Mentor other engineers and champion a culture of innovation, quality, and high-velocity development.

Who You Are:

  • 5+ years of experience in fullstack development with a proven track record of shipping complex, scalable web applications.
  • Deep expertise in at least one modern backend framework (e.g., Node.js/Express, Go, Python/Django) and one frontend framework (Svelte, React, Vue).
  • A strong interest or direct experience in building with Large Language Models (LLMs) and agentic frameworks (e.g., LangChain, LlamaIndex).
  • Experience with microservice architecture, containerization (Docker, Kubernetes), and cloud platforms (GCP, AWS).
  • You are a product-minded engineer who thinks deeply about the user experience and business impact of your work.
