Full Stack JavaScript Developer - Contract

Manchester hybrid (3 days onsite per week)
Outside IR35 £450 - £525 per day

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

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

Experience managing PostgreSQL databases and designing relational data models

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

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
