Job description

About The Role

We're looking for a junior software engineer to join our core team. You'll work across the full stack - backend APIs, database work, frontend interfaces, and integrations - with senior engineers who'll help you grow.

Recommand is infrastructure, not a simple web app. You'll learn to work with APIs, data models, integrations, workflows, event-driven systems, and AI-powered document processing. You'll see how real-world business systems connect and how B2B transactions actually work.

This is a core team role at an early-stage startup. You'll have real ownership and impact from day one.

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

You Should Be

• Curious about how systems work together - not just building screens, but understanding what happens behind them
• Someone who writes code to solve problems, not just to complete tasks
• Comfortable learning fast - you'll encounter new domains (Peppol, ERP, B2B automation) and need to pick them up
• Someone who has embraced AI-assisted development - you use AI tools to learn, build, and move faster
• Excited about open source - you like building in the open or have contributed to open-source projects

Strong Signals

• Personal projects or open-source contributions that show initiative
• You're drawn to how systems work - APIs, databases, and system design - but you also care about building interfaces that feel great to use
• You've built something that connects to an external API or integrates systems
• You're comfortable in the terminal and with Git
• You learn by building, not just by reading

Must-haves

• TypeScript or JavaScript proficiency
• Basic understanding of databases and APIs
• Willingness to work across the full stack
• Based in Belgium, available for hybrid or remote work

Nice-to-haves

• React experience
• PostgreSQL or any relational database experience
• Docker basics
• CS degree or equivalent self-taught depth
• Familiarity with any business domain (finance, logistics, supply chain)

What this is not

• Not a frontend-only role
• Not a pure DevOps/infra role
• Not a large-team environment with months of onboarding
• Not an enterprise environment where you'll work on isolated tickets

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)
