You will collaborate closely with backend engineers, protocol developers, designers, and research teams to deliver seamless and intuitive user experiences for highly technical products.
This position requires someone who can work independently, take ownership of features end-to-end, and maintain high engineering standards in a distributed team environment.
Job Description
In this role, you will be responsible for designing and implementing advanced front-end systems that support Heliax’s decentralized technology stack. You will work on complex dashboards, interactive interfaces, and data-heavy applications that require both performance and scalability.
A major part of your responsibility will be translating sophisticated technical requirements into clean, maintainable, and reusable UI components. You will be expected to contribute to system design discussions and ensure that front-end architecture aligns with long-term product goals.
You will also participate in code reviews, mentor junior engineers when required, and continuously improve front-end development practices within the team.
Key Responsibilities
- Develop and maintain advanced front-end applications using React and modern JavaScript/TypeScript
- Build reusable, scalable, and performance-optimized UI components
- Collaborate with backend and protocol teams to integrate APIs and data systems
- Translate complex technical requirements into clean and functional user interfaces
- Optimize application performance, load times, and rendering efficiency
- Participate in architectural discussions and contribute to system design decisions
- Ensure high-quality code through testing, code reviews, and best practices
- Work in a fully remote, distributed engineering environment
- Troubleshoot and resolve front-end issues across different browsers and devices
- Contribute to improving front-end tooling, workflows, and developer experience
Required Skills & Qualifications
- Strong professional experience in front-end development, especially React
- Advanced knowledge of JavaScript (ES6+) and TypeScript
- Experience with modern front-end frameworks, state management, and component architecture
- Solid understanding of HTML5, CSS3, responsive design, and UI/UX principles
- Experience working with REST APIs and/or GraphQL integrations
- Familiarity with performance optimization techniques for web applications
- Understanding of version control systems such as Git
- Ability to work independently in a remote-first engineering environment
- Strong problem-solving skills and attention to detail
