Overview

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

Join to apply for the Software Architect (Contractor) – Composable Commerce & Event-Driven Design role at Cobble Web - The Online Marketplace Experts

This position is 100% remote, with flexible daily/weekly hours (part-time).

We’re looking for a Software Architect contractor with strong expertise in composable modular architecture and event-driven design to support the next evolution of Sharewise: our marketplace framework that helps entrepreneurs and small businesses launch world-class platforms faster.

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 high-performance marketplaces, and we’re now evolving it into a platform that is modular, event-driven, and future-ready.

We Need Someone Who Can

• Audit and strengthen module isolation (reduce hidden coupling).
• Push us toward a stronger event-driven architecture (pub/sub over direct calls).
• Lay the foundation for customisation: moving from fragile inheritance overrides toward clear extension hooks, composition patterns, and well-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.

• Backend & Core:
  Node.js (Type Script) - Fastify for REST, Apollo for Graph
  
  QL, TypeORM, Redis, Postgre
  
  SQL.
• Side deps: chalk, chokidar, commander, winston, class-transformer, class-validator.
• Frontend:
  Next.js v15 & React v19.

• Mid-Senior level

• Full-time

• Engineering and Information Technology
• Industries:
  Technology, Information and Internet
