## Description

We\'re looking for a senior software engineer to join our core team. You\'ll work across the full stack of our platform - from API design and database modeling to frontend interfaces and integrations., We\'re looking for a senior software engineer to join our core team. You\'ll work across the full stack of our platform - from API design and database modeling to frontend interfaces and integrations.
Recommand is infrastructure, not a CRUD app. You\'ll work on APIs, data models, integrations, workflows, event-driven systems, and multi-tenant architecture. You\'ll connect systems, map data, handle edge cases, and deal with the realities of ERP integration and business document exchange.
This is a core team role. You\'ll shape the platform, not just build features on top of it.
What you\'ll work with

 * Runtime: Bun
 * Backend: Hono, TypeScript, OpenAPI + Zod
 * Frontend: React 19, Vite, TailwindCSS
 * Database: PostgreSQL with Drizzle ORM
 * Infrastructure: Docker
 * Monorepo: Bun workspaces, * Not a frontend-only role
 * Not a pure DevOps/infra role
 * Not a feature-building product engineering role
 * Not a rigid enterprise environment

How we work

 * Small, hands-on, technical team
 * Hybrid or remote - based in Belgium, with presence at Corda Campus, Hasselt when needed
 * AI-assisted development is the default, not the exception
 * Open source core - we build in the open
 * Full-time engagement (employee or contractor)
