About The Role
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.

About The Role
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

What we\'re looking for
You Should Be

  • A systems thinker - comfortable with APIs, data models, event-driven architecture, and multi-system integration
  • Full-stack with a platform mindset - you\'re strong in backend and infrastructure, but you also care about building great UI and UX
  • Pragmatic - you build v1s, evolve architecture, and thrive with changing requirements
  • Comfortable with ambiguity - this is an early-stage startup, not a feature factory
  • Someone who has embraced AI-assisted development - you use AI tools daily and know how to leverage them effectively
  • Passionate about open source - you care about building in the open and value extensibility

Strong Signals

  • Built or maintained an API platform, SDK, or developer tool
  • Integration-heavy product experience - connecting external systems, handling messy data
  • Open-source contributor
  • Experience with workflow engines, automation tooling, or event-driven systems
  • ERP integration, fintech, or invoicing experience
  • Startup experience - you\'ve built from zero

Must-haves

  • Strong TypeScript / Node.js (or Bun)
  • Solid database and API design skills
  • Integration mindset - you enjoy connecting systems
  • Based in Belgium, available for hybrid or remote work

Nice-to-haves

  • React experience
  • Peppol or e-invoicing knowledge
  • Experience with B2B or supply chain systems
  • Familiarity with Belgian/EU compliance landscape

What this is not

  • 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)
