Job description

AI-assisted development is becoming a normal part of modern software engineering. This role is for a developer who wants to work that way, not just read about it.

You will join a software business building technology for the eCommerce and logistics sector, where AI-assisted and agentic development practices are already influencing how the team designs, builds and improves software.

Commercial experience with AI development tools would be useful, but it is not essential. What matters is that you are genuinely curious, technically engaged and already experimenting with AI-assisted development, either at work or in your own time.

The role

You will join an experienced development team working on a greenfield project for the company’s parent group, alongside the ongoing development and improvement of existing software products.

This is a balanced full-stack role, covering front-end development, APIs, back-end services, databases, cloud platforms and deployment pipelines. You do not need to be equally strong in every area, but you should enjoy working across the stack and be comfortable moving between user-facing features and server-side development.

The team is using AI-assisted development as part of its day-to-day engineering approach, including tools such as Claude, Cursor, GitHub Copilot or similar. You do not need to have used these commercially, but you should be interested in how AI can improve development speed, code quality, testing, problem solving and delivery.

You will be involved in:

• Creating clean, tested and maintainable TypeScript code across front-end and back-end services
• Building and improving user-facing features, APIs and core platform functionality
• Working with databases, cloud services and deployment pipelines
• Using AI-assisted development tools as part of your coding workflow
• Contributing to modern development practices, including the team’s approach to agentic AI
• Working with product owners, developers and technical leadership to shape technical solutions
• Supporting, maintaining and improving existing services

You should have experience with:

• React, Next.js or similar front-end technologies
• REST APIs, ideally with Express, Nest.js or similar
• MongoDB and/or relational databases
• Unit testing with Jest or similar
• Clear communication and collaborative software development

Useful experience includes:

• AI-assisted development tools such as Claude, Cursor, Claude Code, GitHub Copilot or similar
• Personal or commercial experience experimenting with LLMs, coding agents or agentic development workflows
• Docker and Docker Compose
• Continuous Delivery or Continuous Deployment
• Feature flagging, dark launching, Kubernetes, serverless or GitOps principles

The company uses GCP, but strong AWS or Azure experience is also welcome if you are interested in moving further into Google Cloud.

This will suit a full-stack developer who enjoys building software, likes working with modern tools and is open-minded about how AI is changing development.

You do not need to be an AI specialist. You do need to be the kind of developer who keeps learning, tries new tools, thinks carefully about quality and wants to understand how AI-assisted development can be used properly rather than just talked about.
