About Us

We're MuseCool, London's largest music school, now building The Muse, an innovative platform that assists music tutors in delivering personalised lessons and improving student engagement.

You'll help us develop a cutting-edge music lesson understanding engine, to be used in thousands of real lessons. Expect messy audio, real students, real tutors, real data, and the chance to build something no one has built before.

This is a fully remote role for Ukraine-based candidates. We work with an overlap with London hours.

The Role

We're hiring a Frontend Engineer (Music Education Games) to build interactive music-learning interfaces that respond to live piano playing. Games will be integrated with our real-time lesson analysis engine and become one of the high-value features of our solution.

This isn't static web development, it's about creating smooth, engaging, and playful musical experiences where timing, visual feedback, and audio synchronisation must all work flawlessly together.

You'll work with our team of engineers to turn analysis outputs into delightful, effective learning games for children.

What You'll Work On

• Build interactive music game interfaces with real-time visual feedback for piano practice
• Create original game mechanics with real-time performance feedback
• Implement smooth, performant animations and transitions that respond to live audio analysis
• Optimise for timing precision and implement responsive interfaces that work across devices
• Balance polish with pragmatism. Ship features that work, then iterate

Requirements

• Strong frontend fundamentals (Next.js + React + TypeScript)
• Experience building performant, interactive web interfaces with complex timing requirements
• Experience with animation, transitions, and creating smooth user experiences
• Basic music knowledge (played an instrument at an amateur level or above)
• Comfortable working remotely with some overlap with London hours

Nice-to-Haves

• Experience with animation libraries like GSAP, Framer Motion, or similar
• Experience with Canvas, SVG animation, or game-style rendering
• Familiarity with animation tools like Rive, Lottie, or After Effects
• Experience with game development, education apps, or interactive multimedia
• Knowledge of Web Audio API or audio-visual synchronisation
• Familiarity with MIDI and music notation rendering (Verovio, etc.)
• Experience with real-time systems or performance optimisation
• Mobile development experience (React Native or similar)
• Some backend or full-stack experience. Useful when a feature needs API support or cross-stack changes
• Background in children's educational content
• Curiosity about music pedagogy and learning psychology

Don't tick every box? Apply anyway if you're passionate about music education technology and eager to learn - we value curiosity and drive as much as experience, and we want people who can grow into the role.

What We Offer

• $2,000–3,000/month depending on experience
• Autonomy, ownership, and the chance to build something truly original
• Rapid development and growth as the company scales
• Weekly online instrument lessons - you get too choose which instrumet you want :)

To Apply

Please provide the following with your application:

• CV
• Link to 1-2 projects you've built (live demo, repo, or portfolio)

Interviews ongoing - we hire fast when we meet the right person!

Who we are:
Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries.
 

About the Product:
The product is a fast-growing online entertainment platform focused on delivering browser-based games along with real-time interactive features. It serves an expanding audience and operates under conditions of high traffic, strict latency requirements, and secure micro-transaction processing within a social gaming environment.

The platform relies on a hybrid technology stack that combines a legacy codebase built with a widely used DOM-manipulation library and modern solutions based on React and Next.js. Current challenges include transforming legacy parts into a scalable, component-based architecture, implementing real-time interactions using WebSockets, maintaining consistency across mobile devices and browsers, and integrating payment and promotion management systems.

Strong engineering ownership is key to ensuring system stability, improving performance, and enabling fast, scalable feature delivery.

About the Role:
In this role, you will take ownership of frontend feature delivery from idea to production. You will work closely with frontend leadership, backend engineers, designers, QA, and DevOps to build and evolve a complex product.

A key part of your work will be driving the transition from a jQuery-based architecture to a modern React/Next.js setup. You will be expected to make architectural decisions, improve development workflows, and ensure high standards of performance, security, and code quality.

This position requires strong independence, solid technical judgment, and the ability to work in a fast-paced, evolving environment.
 

Key Responsibilities:

• Improve and maintain existing jQuery-based interfaces
• Build scalable and responsive UI using React and Next.js
• Refactor and structure CSS/SCSS for long-term maintainability
• Ensure cross-browser compatibility and strong mobile experience
• Implement and support real-time features using WebSockets
• Apply frontend security best practices
• Contribute to the design of a reusable component architecture
• Integrate APIs and collaborate closely with backend teams
• Set up and improve build tools and performance monitoring
• Implement and manage state using Redux, MobX, or similar
• Work with designers to deliver high-quality UI
• Develop key features such as payments, authentication, and promotions
   

Required Competence and Skills:

• 6+ years of experience in frontend development on production systems
• Strong experience working with legacy codebases (jQuery)
• Solid knowledge of React (Hooks, functional components)
• Hands-on experience with Next.js (SSR, SSG, API routes)
• Strong CSS/SCSS skills and responsive design expertise
• Proficiency in JavaScript (ES6+) and TypeScript
• Experience with WebSockets and async patterns
• Understanding of performance optimization and Core Web Vitals
• Familiarity with build tools like Webpack, Vite, or Gulp
• Experience integrating REST APIs
• Strong debugging and cross-browser troubleshooting skills
• Experience with state management libraries
• Git proficiency and experience working in teams
• Strong communication skills and ability to work independently
   

Nice to Have:

• Experience introducing TypeScript into existing projects
• Basic knowledge of PHP
• Experience with testing tools (Jest, RTL, Cypress)
• Experience with animation libraries like GSAP
• Familiarity with design tools (Figma, Zeplin, etc.)
• Understanding of CI/CD processes
• Knowledge of SEO and analytics
• Experience with hybrid mobile solutions (e.g., Cordova)
   

Why Us:

• We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in). 
• We provide full accounting and legal support in all countries we operate. 
• We offer a highly competitive package with yearly performance and compensation reviews.
