Cannaleo Digital GmbH

Backend Engineer

• Platform development: You will develop core modules of our multi-vendor marketplace platform based on a headless commerce framework (Medusa JS or comparable) — from product and batch management and pricing/conditions logic to order and quote flows.
• Backend logic: You will implement business logic for customer-specific price lists, tiered pricing, bundles, minimum and maximum quantities, approval flows, and resale between vendors.
• Domain modeling: You will model pharma-specific requirements accurately — including batches (expiry date, COA, THC/CBD values), FEFO/FIFO logic, and inventory tracked at batch and packaging-unit levels.
• APIs and integrations: You will design and develop REST/GraphQL interfaces to wholesale ERPs, pharmacy merchandise-management systems, and, prospectively, DMS/archival systems.
• Frontend: You will implement admin UIs, vendor backoffices, and storefronts with React/Next.js and work closely with the design team to deliver a thoughtful, high-performance UX.
• Multi-vendor & single sign-on: You will design the technical implementation of the multi-vendor checkout (including multi-vendor shipping) as well as white-label vendor shops with unified SSO across the marketplace, vendor shops, and the existing Cannaleo inventory system.
• Code quality and operations: You will establish robust testing and CI/CD standards, focus on performance, security, and maintainability, and operate the platform in production together with the team.
• Technical conception: You will actively participate in architectural decisions, document interfaces, and make pragmatic trade-offs between clean architecture and delivery velocity.
