Full Stack Developer (MERN Stack, React, Next.js)

Who We Are:

At Hunt St, we help Australian companies hire top remote talent in the Philippines. For this role, you will be engaged directly by the client as an independent contractor. We are not an outsourcing agency. All of our roles are 100% remote so you'll be able to work from home.

The client is an Australian digital learning and technology company specializing in creating engaging, interactive online learning experiences. Since 2014, they have been helping organizations turn complex information into practical, memorable, and enjoyable digital learning through instructional design, interactive technology, video, animation, and custom software.

The business is expanding its development team to support the growth of its software products, including a digital learning marketplace and a learning creation platform.

Role Overview:

This is a hands-on full stack development role for someone comfortable stepping into an existing codebase, understanding its workflow, and improving it without needing a complete rebuild. You'll work across the MERN stack, including Node.js, Express, MongoDB, Mongoose, React, Redux, and Next.js. The role spans multiple React generations, from older Create React App code to React 18, React 19, and Next.js 16.

For the right candidate, there is potential for long-term ongoing development work as the products continue to evolve.

Key Responsibilities:

The developer will own features end-to-end, from the MongoDB model through the Express API to the React screen, in codebases they did not write.

• Take ownership of development work from MongoDB data model through Express API to the React frontend
• Take over and become familiar with the existing codebase developed by 3rd Digital
• Get applications running locally and understand how repositories, environments, and services fit together
• Document setup, architecture, processes, and technical decisions as you learn the system
• Build and fix features in Genesis, TMRW's learning creation platform
• Develop functionality within Genesis's drag-and-drop learning editor using React and related libraries
• Build and maintain interactive learning objects such as flip cards, hotspots, accordions, video, 3D, and parallax components
• Maintain the SCORM 1.2 export and preview functionality so published courses work correctly within clients' learning management systems
• Contribute to SensAI, TMRW's AI-powered course-writing assistant using the OpenAI API
• Build and maintain features in Cosmos Public, the creator-led Next.js learning marketplace
• Develop marketplace functionality covering learning experiences, pricing, delivery methods, and subscriptions
• Build and maintain subscription and billing functionality for separate learner and creator plans
• Work with Stripe for subscription payments and invoices
• Design and modify Mongoose models, database queries, indexes, and REST API endpoints
• Maintain and extend the shared Node.js/Express backend supporting Genesis, Cosmos, subscriptions, and administration
• Work with authentication and sessions, including email/password authentication, Google sign-in, magic links, and two-factor authentication
• Build and maintain administration functionality covering users, content, analytics, and master data
• Work across older React applications as well as newer React 18/19 and Next.js applications
• Safely improve or upgrade older code and dependencies where appropriate
• Introduce automated tests into areas where testing is currently limited or absent
• Test your own work thoroughly before handing it over for review
• Work through Git feature branches and pull requests using Bitbucket
• Communicate progress, blockers, risks, and technical concerns clearly and early
• Work to agreed priorities and timelines set with the CEO
• Document important technical decisions and processes to make the codebase easier for future developers to work with

Requirements:

Must Have:

• 3+ years of commercial experience in full stack JavaScript development
• Strong experience with Node.js and Express, including building REST APIs, authentication, and session management
• Strong experience with MongoDB and Mongoose, including schema design, indexing, queries, and working with existing data and migrations
• Strong experience with React and Redux, including working across older Create React App codebases and modern React 18/19 applications, as well as Next.js
• Comfortable working with existing codebases that have limited documentation and automated testing
• Strong understanding of Git, including feature branches, pull requests, and submodules
• Clear written English and the ability to provide effective async updates to an Australian team

Nice to Have:

• Knowledge of e-learning technologies and standards such as SCORM, xAPI, or LMS integrations
• Familiarity with drag-and-drop and rich-text editors such as GrapesJS, Craft.js, Tiptap, or CKEditor
• Stripe subscriptions, billing, and tiered plans
• OpenAI or other LLM API integration
• Electron or Capacitor apps
• Automated testing with Jest or React Testing Library, plus modernizing older dependencies
• Interactive frontend libraries such as GSAP, Lottie, or three.js
• Experience working alongside AI coding assistants

Work Arrangement & Expectations:

This is a remote role set up as an independent contractor engagement. Successful candidates will be expected to:

• Disclose any existing ongoing roles or client work
• Reflect this engagement on their LinkedIn profile (clearly marked as “Independent Contractor”)
