Junior Full Stack Developer

Position Summary As a Junior Level fullstack developer at CST Training, you will design, build and maintain web applications across the entire stack. Joining a small but talented development team and reporting directly to the Lead Developer, you will ship features end-to-end – from database schema design through to building full applications including APIs, backend services and polished, responsive user interfaces. This is a hands-on role where your work will have a direct, visible impact on our learners and operations.

Essential Duties & Responsibilities

Build and maintain fullstack web applications using React (TSX/JSX) on the frontend.
Develop APIs and backend services using Node.js to support frontend functionality.
Design, implement, and optimise MySQL databases, including schema design, queries, and performance tuning.
Write clean, maintainable, well-tested code that scales.
Collaborate with stakeholders to translate business requirements into technical solutions.
Troubleshoot, debug, and resolve issues across the stack.
Participate in planning, estimation, and architectural discussions.

Strong proficiency in React with TypeScript (TSX) and/or JSX.
Solid experience with Node.js and a backend framework such as Express (or NestJS, Fastify) for building APIs and services.
Hands-on experience with Next.js or similar modern React frameworks.
Solid experience designing and working with MySQL databases (schema design, joins, indexing, query optimisation).
Experience building and consuming RESTful APIs.
Familiarity with state management (Redux, Zustand, React Query, or similar).
Experience with automated testing (Jest, Vitest, Playwright, or Cypress).
Familiarity with version control (Git) and collaborative development workflows.
Strong problem-solving skills and the ability to work independently.
Excellent written and verbal communication.

Nice to Haves

Experience with cloud platforms (AWS, Azure, GCP, or Hetzner).
Exposure to CI/CD pipelines and DevOps practices.
Background in the EdTech or training sector.
Experience in Linux environments
Familiarity with Docker or other containerisation tools.
Experience with authentication/authorisation systems (OAuth, JWT, SSO).

Professional Development

Stay up to date with the latest developments in the React, Node.js, and wider web ecosystem.
Receive mentorship and code review from the Lead Developer.
Participate in relevant training and certification programs.
Contribute to the improvement of internal engineering practices and tooling.
Opportunity to progress into senior development roles or specialise in areas such as backend architecture, DevOps, or technical leadership.

Career Growth

Advance to a Senior Fullstack Developer position.
Specialise in key areas such as backend systems, frontend architecture, or DevOps.
Take ownership of larger projects and contribute to technical direction.
Gain recognition as a technical expert within CST Training and beyond.

Core Competencies

Problem Solving – Takes a proactive approach to resolving technical challenges across the stack.
Teamwork – Works collaboratively within a small development team.
Communication – Clearly articulates technical decisions and progress to both technical and non-technical stakeholders.
Time Management – Manages workload effectively to deliver features on schedule.

Adaptability – Adjusts to changing requirements and evolving technologies.
