Technical Tools

Desktop EngineerInfrastructure & Cloud

We are seeking a skilled Frontend Desktop Engineer to develop and maintain a cross-platform peer-to-peer (P2P) communications application built with React and powered by a decentralised runtime. In this role, you will contribute to an innovative software environment that enables direct application connectivity without relying on traditional server infrastructure. You will work across user interface development, application architecture, state management, testing, and performance optimisation to deliver a seamless desktop experience. Collaborating with a globally distributed engineering team, you will help build reliable, responsive, and maintainable applications for multiple operating systems. You will also have the opportunity to explore P2P networking, real-time communication, and decentralised technologies that support greater user privacy and control over personal data. This role is ideal for an engineer who enjoys solving complex frontend challenges and contributing to forward-looking technology in a remote, innovation-driven environment.

Develop, maintain, and enhance a cross-platform desktop communications application using React or Preact, JavaScript/TypeScript, and the Pear runtime.
Implement intuitive, responsive user interfaces and translate product requirements and design concepts into reliable frontend experiences.
Build and maintain application state management solutions using tools such as Redux, Redux Toolkit, Zustand, or comparable libraries.
Write modular, maintainable, well-tested code that follows established engineering standards and supports long-term scalability.
Test, debug, and troubleshoot complex frontend applications, identifying and resolving functional, performance, and stability issues.
Optimise application performance, including rendering efficiency, memory management, responsiveness, and resource utilisation.
Contribute to cross-platform desktop application development and help ensure consistent behaviour across macOS, Windows, Linux, and other supported environments.
Work with peer-to-peer networking and distributed application technologies to support reliable connectivity, data exchange, and decentralised communication.
Integrate and support real-time communication capabilities, including audio and video functionality where applicable.
Collaborate with engineers and other stakeholders in a remote, globally distributed team to plan, implement, review, and deliver software improvements.
Participate in code reviews, testing, debugging, and continuous improvement of frontend architecture and development practices.
Contribute to the evolution of decentralised applications by identifying technical challenges and proposing practical, maintainable solutions.
