  • Implement a flexible architecture to support future integrations with other eCommerce and ERP platforms.
  • Set up multi-tenant SaaS functionality, user management, authentication, and billing.
  • Deploy, monitor, and scale the application in a secure cloud environment.
  • Collaborate directly with the founder on roadmap, prioritization, and execution.

✅ Knowledge of vector databases, embeddings, and agent-based AI workflows.

✅ Exposure to B2B or enterprise SaaS products.

✅ Comfort with cloud infrastructure and CI/CD pipelines.

Why Join Us?

  • Work with the industry leaders of B2B eCommerce and help define the future of intelligent selling.
  • Be the founding engineer of a high-impact AI product in a massive B2B commerce space.
  • Help shape the future of intelligent selling, starting with Shopify and expanding far beyond.
  • Own your work, ship fast, and see your impact immediately.
