Description du poste

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
• Frontend: React 19, Vite, TailwindCSS
• Database: PostgreSQL with Drizzle ORM
• Infrastructure: Docker

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
• 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 skillsBased in Belgium, available for hybrid or remote work

Nice-to-haves:

• 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)
