Node.js Contractor – AI Tool Replatforming

Remote | Outside IR35 | £450–500/day


We are looking for an experienced Node.js contractor to help replatform and modernise an internally developed AI-driven data platform.


The existing tool was rapidly developed by a member of the technical team using AI-assisted development tools and is currently running locally on a laptop environment.

We now need an experienced engineer to rewrite/refactor the application into a secure, production-ready Node.js solution suitable for deployment within our server infrastructure.


The Role

You will take ownership of analysing the current Python-based application and rebuilding/refactoring it into a scalable and maintainable Node.js platform.

The application:

  • Pulls data from multiple external sources including:
  • RSS feeds
  • Websites
  • APIs
  • Processes and stores data within a database
  • Includes a front-end interface for displaying and interacting with the data

A key part of the engagement will be ensuring the rebuilt platform is secure, robust, and capable of passing penetration/security testing.


Required Skills & Experience

  • Strong commercial experience with Node.js
  • Experience refactoring or rewriting existing applications
  • Solid understanding of secure software engineering practices
  • Experience building applications that integrate with APIs, web scraping, and data feeds
  • Database design and integration experience
  • Front-end development capability (React/Vue/modern JS frameworks beneficial)
  • Experience deploying applications into production server environments
  • Understanding of authentication, security hardening, and application resilience
  • Ability to work independently and make pragmatic architectural decisions


Desirable

  • Previous experience working with AI/LLM-powered applications
  • Python experience to help interpret the existing codebase
  • Experience preparing systems for penetration testing/compliance review
  • DevOps/cloud infrastructure experience


Contract Details

  • Contract: Outside IR35
  • Rate: £450–500 per day
  • Location: Fully remote
  • Start: ASAP
  • Duration: Initially 10-12 weeks but potential for extension


We’re looking for someone pragmatic, technically strong, and comfortable taking an early-stage internal tool and turning it into a secure, production-grade platform.
