Full-Stack Engineer Intern - React, Next.js & Python
Remote | Duration: 6 Months | Start Date: 6 July 2026 | Commitment: ~20 hours per week | Eligibility: Students enrolled in a credit-bearing UK university placement | Application Deadline: Sunday 28 June 2026 | Unpaid (credit-bearing, contributing towards your degree)
About the Opportunity
NexCell Solutions is building a production-grade, AI-powered SaaS platform used by live clients, and we need strong full-stack hands to help ship it. This is not coursework simulation or a demo project: you will design, build, and ship real product features, from responsive interfaces through to the APIs behind them, inside a professional engineering environment.
The role spans the full development lifecycle, from pixel-accurate UI through to backend endpoints and real-time data. It is built for students with strong frontend foundations who want to grow into full-stack engineering, with direct mentorship from NexCell's senior engineers. The work rewards initiative, attention to detail, and a bias towards shipping.
What You Will Do
- Build responsive, high-performance UI components using React and Next.js
- Translate Figma designs into pixel-perfect, production-ready interfaces
- Develop dashboards for monitoring AI-driven conversations and system activity
- Design UI components that visualise AI outputs, analytics, and system insights
- Build and maintain FastAPI REST endpoints powering product features and automations
- Implement real-time UI updates using WebSockets for live data streams
- Take part in early architectural discussions, implementation decisions, and testing
- Apply structured development practices focused on security, reliability, and user trust
- Write clean, maintainable, well-documented code across the full stack
- Collaborate with senior engineers on API contracts and feature UX
- Push production-quality code to GitHub as part of a real AI SaaS product
Who This Is For
- Students with a strong frontend foundation looking to expand into full-stack engineering on a real product
- Students currently enrolled in a Bachelor's or Master's degree that includes a credit-bearing placement or internship module
- Fast learners who enjoy solving complex problems and can work independently
- Individuals interested in SaaS platforms, AI-powered products, and end-to-end engineering
- Those able to balance academic commitments with a structured part-time internship
- Reliable, disciplined contributors who communicate progress clearly and work well in written English on a remote team
Preferred Background
Currently studying Computer Science, Software Engineering, Data Science, Artificial Intelligence, or a related technical discipline. Solid frontend fundamentals are essential: hands-on experience with React and modern JavaScript (ES6+), with familiarity with Next.js or TypeScript strongly preferred. Additional exposure to any of the following is a plus: Tailwind CSS, Python and FastAPI, building or consuming REST APIs, Git and GitHub workflows, or a basic understanding of AI-backed systems such as LLMs, automation pipelines, or analytics dashboards.
Tech Stack Exposure
- Frontend: Next.js 14, React, TypeScript, TailwindCSS, shadcn/ui
- State Management: React Hooks, Context API, TanStack Query
- Backend: Python, FastAPI (REST APIs powering AI features)
- Real-time: WebSockets for live data streams
- AI Layer: LLM integration, AI-generated insights, automation controls
- Charts & Visualisation: Recharts, D3.js
- Design Handoff: Figma to code
- Version Control: Git, GitHub
How to Apply
Submit your application by email to with:
- Your CV with a cover letter
- A short paragraph (maximum 150 words): \"Describe a frontend or full-stack project you recently built. What did you learn from it?\"
