Job title: Senior Full Stack Developer (TypeScript, React, Node.js)
Type: Full-time, Contract (3 months initially)
Location: Edinburgh, Newcastle, Leeds, Manchester or London

In this role, you will:

Join a product team to help deliver critical deadlines where additional capacity is needed.

You’ll work hands-on across the stack using TypeScript, React and Node.js (Express), using AI-assisted development tools as part of your day-to-day workflow.

You’ll take ownership of small, clearly defined, high-volume tickets that unblock wider delivery, working within a domain-driven team under experienced engineering leadership.

You’ll build and extend services on AWS with MongoDB, working within a monolith or modular MVC-style architecture and established CI/CD pipelines (Bitbucket, Jenkins).

You’ll write well-tested code and help raise the bar on testing within the team.

Why this role

You’ll be expected to contribute quickly within a live system, getting up to speed and delivering value within days, not weeks.

Work is broken down into small, well-defined tasks to maximise delivery speed and reduce ambiguity.

You’ll work under experienced team leads with clear direction, within a team already using AI-assisted workflows and evolving its testing approach.

This is a focused engagement designed to increase delivery capacity without disrupting existing teams.
