I'm working with a SaaS start-up in the B2B retail space. They've just closed Series A and are kicking off a new payments platform for their client base. They're building smart tools for retailers to manage suppliers, stock, and payments all in one place.

They need a strong full stack JavaScript contractor to help lead this greenfield build. You'll be working closely with the CTO and product team to bring the new feature to life.

The stack:

  • Frontend: Vue3, TypeScript
  • Backend: Node.js, PostgreSQL, Stripe API, GraphQL exposure, RESTful API design
  • Infrastructure: Docker, AWS, CI/CD Pipelines

What they need from you:

  • 5+ years of full stack JavaScript experience with strong commercial use of Vue and Node
  • Ability to design, develop and document scalable APIs and microservices
  • Comfortable integrating third-party services (Stripe experience essential)
  • Experience managing PostgreSQL databases and designing relational data models
  • Strong TypeScript fundamentals and ability to enforce typing and testing standards
  • Familiar with containerised environments and deploying via AWS
  • Confident in handling security, authentication and role-based access at scale
  • Ability to work independently and make architectural decisions when needed
  • Experience in Agile teams and communicating directly with product/CTO maintainable code

Why this one's worth a look:

  • Fully greenfield project
  • Direct influence over how it's built
  • Outside IR35
  • Clean, modern stack
  • Fast feedback loop and minimal red tape
