The Opportunity

We are looking for an experienced Senior Full Stack Developer with strong Node.js expertise and a solid background in React and Next.js to join an established digital transformation team currently going from strength to strength and undergoing an exciting period of transformation.
This is a permanent opportunity for a senior engineer who wants genuine technical ownership and the opportunity to make a significant impact on a business-critical digital platform.

You'll join the team at an important stage of the programme, helping to modernise and refactor an existing business-facing management platform used to support complex operational and management workflows.
The role is highly hands-on, with a particular focus on Node.js backend development, API architecture and application modernisation, alongside contributing to a modern React/Next.js frontend.

You'll have the opportunity to influence technical decisions, improve performance and scalability, and help shape the long-term architecture of the platform.

About the Role

As a Senior Full Stack Developer, you'll take ownership of key areas across the backend and frontend, with a particular emphasis on Node.js and API development.
You'll work closely with other engineers, UX/UI specialists, product teams and stakeholders to deliver high-quality, scalable digital products.
You'll be comfortable working autonomously, making technical decisions and contributing from day one, while also being a collaborative member of a wider delivery team. This is a role suited to someone who enjoys working across the stack but has a strong backend bias and genuine depth in Node.js.

Key Responsibilities
Lead and contribute to the modernisation and refactoring of existing applications
Design, develop and maintain robust Node.js backend services and APIs
Develop and maintain OpenAPI-driven backend services
Design and implement scalable API architectures and integrations
Work with PostgreSQL and Prisma ORM to develop efficient data access and persistence layers
Identify opportunities to improve backend performance, scalability, security and maintainability
Contribute to the development of the frontend using React and Next.js
Work with Next.js App Router, Server Components and Server Actions where appropriate
Build and integrate APIs across the frontend and backend
Implement and optimise client-side and server-side caching strategies
Develop automated tests using technologies such as Playwright
Work closely with other engineers to define technical approaches and maintain high engineering standards
Contribute to technical architecture and make pragmatic engineering decisions
Collaborate with UX/UI, product and delivery teams to translate requirements into scalable technical solutions
Contribute to the refinement of user stories, requirements and delivery plans
Participate in stakeholder discussions and technical presentations where required
Support the continued evolution of engineering practices, standards and ways of working

You'll Ideally Have

Experience working with OpenAPI or API-first development
Strong understanding of backend architecture, application design and software engineering principles
Commercial experience with React.js and Next.js
Experience working across both frontend and backend applications
Experience with PostgreSQL and/or relational databases
Experience with Prisma or a similar ORM
Proven experience delivering application refactors, migrations or significant modernisation programmes
A strong understanding of performance, scalability, security and maintainability
Experience writing automated tests and working with modern testing frameworks
Experience with Docker and modern CI/CD practices
The ability to work independently and take ownership of technical decisions
Strong communication skills and confidence working with both technical and non-technical stakeholders
A proactive, collaborative and delivery-focused approach
Experience working within enterprise or complex digital transformation environments would be advantageous

Why Join?

This is an opportunity to take on a genuinely senior Full Stack engineering position with real technical and architectural ownership, rather than simply delivering tickets against an established roadmap.
You'll be joining a high-profile digital transformation programme where your technical decisions will directly influence the performance, scalability and future direction of a business-critical platform.
The role has a particularly strong Node.js/backend focus, making it a great opportunity for an engineer who wants to work on meaningful backend architecture while retaining the ability to contribute across the full technology stack.
You'll work with modern technologies, collaborate with experienced technical and delivery teams, and play a significant role in the continued evolution of an enterprise digital product. xohmjla
