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
