Software Architect (Contractor) – Composable Commerce & Event-Driven Design
Lisboa
Lisboa, Lisboa, Portugal

Overview

We’re looking for a Software Architect contractor with strong expertise in composable modular architecture and
- driven design to support the next evolution of Sharewise: our marketplace framework that helps entrepreneurs and small businesses launch
- class platforms faster. This position is 100% remote, with flexible daily/weekly hours (part-time).

This isn’t a “keep the lights on” role. You’ll be shaping the backbone of a framework designed to democratise marketplace creation and empower communities. Sharewise is built on 12+ years of Cobble
Web’s experience delivering
- performance marketplaces, and we’re now evolving it into a platform that is modular,
- driven, and
- ready.

We Need Someone Who Can

• Audit and strengthen module isolation (reduce hidden coupling).
• Push us toward a stronger
  - driven architecture (pub/sub over direct calls).
• Lay the foundation for customisation: moving from fragile inheritance overrides toward clear extension hooks, composition patterns, and
  - documented integration points. This is about more than code style: it’s about making Sharewise a framework where developers can confidently adapt and extend features without breaking core stability.
• Make the platform easier to scale, extend, and maintain, both for our team and for external developers.
