We are building Quasible, an AI-first, modular, open-source business platform designed for European SMEs.
Think “Odoo meets AI-native architecture” — built from scratch with modern tooling, type-safety, modularity, and openness at its core.

You will join the core engineering team responsible for building the first version of the platform, together with experienced engineers from the client side (Right on Skill) and from Unlocking Tech.

🌍 About Quasible

Quasible is a next-generation platform for SMEs, aiming to unify:

• AI-powered document management
• Business workflows
• Collaboration
• Modular “App Store” with installable apps
• Extensibility through a public TypeScript SDK

The entire platform is:

• AI-first from day one
• Open source (LGPL-3.0)
• Contract-first (shared types & schemas end-to-end)
• Built for modularity (apps, permissions, dynamic loading)

🧠 The goal: create a scalable open ecosystem for European businesses, with AI embedded in every workflow.

🧩 Tech Stack You Will Work With

Frontend

• TanStack Start (modern alternative to Next.js)
• React + TypeScript
• Sackberry (server state + React Query ecosystem)
• Component composition, lazy loading, dynamic module loading
• Biome (formatter/linter)

Backend / Platform (you will consume)

• ORPC (Object RPC, contract-first)
• Drizzle ORM
• PostgreSQL + pgVector
• Redis
• Ingest (task/workflow engine)
• AI Gateway (multi-provider LLM orchestration)

DevOps

• Monorepo with Turborepo
• Docker
• Railway.app
• Cloudflare R2
  
  🎯 Your Responsibilities
• As one of the first frontend engineers, you will shape the platform:
• Build the core frontend architecture (auth, orgs, billing, dashboard, App Store UI).
• Contribute to the contract-first architecture (Zod/TypeBox schemas, shared types).
• Implement dynamic modules, lazy loading, and UI extensibility patterns.
• Develop the first functional module, e.g. document management with AI semantic search.
• Collaborate closely with backend engineers and the technical lead on ORPC & SDK integration.
• Write maintainable, type-safe, test-covered code.

• Participate actively in open source—PRs, reviews, documentation, and community engagement.

  
  🧑‍💻 Requirements

• 5+ years experience building modern React apps
• Strong expertise in TypeScript and type-safe architectures
• Experience with modern React frameworks (Next.js, Remix, TanStack, etc.)
• Solid understanding of state management + server state
• Experience with monorepo structures (Turborepo, Nx, etc.)
• Comfortable working with contract-first APIs, Zod, or similar
• Strong testing mindset (unit + integration)

• Good communication and ability to collaborate in a senior, distributed engineering team

  
  Nice to have

• Experience contributing to open source
• Familiarity with PostgreSQL, AI/LLM integrations, or ORPC/TRPC
• Backend TypeScript knowledge
• Interest in building developer tools / SDKs / internal frameworks
