About the role

Key responsibilities & impact

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.

Requirements

What you’ll need

Strong hands-on experience with Node.js and TypeScript in production web applications.
Experience with headless commerce or e-commerce frameworks based on Node.js/TypeScript — e.g. Medusa JS, commercetools, Saleor, Shopware, or similar.
Willingness to dive deep into Medusa JS if not already used in production.
Solid knowledge of React and Next.js for building admin interfaces, vendor backoffices, and storefronts.
Experience designing and building REST and/or GraphQL APIs and integrating external systems (ERP, merchandise-management systems, external services).
Good knowledge of PostgreSQL (data modeling, indexing, performance) and experience with ORM tools.
Confident use of Git, CI/CD pipelines, and Linux-based deployment environments.
Autonomous, structured way of working in a remote environment, clear communication, and teamwork.
German language skills at least C1 (business fluent) — our customers, partners, and technical terminology are German-speaking.
Nice-to-have: Practical production experience with Medusa JS (modules, workflows, events).

Benefits

Comp & perks

100% remote work from Germany with flexible hours.
