REMOTE GLOBAL | KEEPGO

Format: Full-time (170 hrs/mo), remote, long-term

Keepgo— a global mobile internet provider offering innovative products and solutions based on virtual technologies, primarily eSIM.

We are looking for a highly experienced Frontend Developer (JavaScript / Vue.js) to strengthen the team's frontend expertise and develop a mobile application on Capacitor (iOS + Android).

Responsibilities:

• Development and enhancement of the mobile application on Capacitor (web-tech within a native wrapper, publication in the App Store and Google Play)
• Development of the user web cabinet and admin interfaces
• Collaboration with the backend team on REST API design and integration
• Ensuring performance, responsiveness, and cross-browser compatibility of interfaces
• Participation in code reviews, writing tests, maintaining code quality
• Working with existing code and its gradual refactoring
• Automate repetitive tasks using AI agents (building screens for a new partner brand, connecting to APIs, testing on devices) — gradually reducing typical releases from days to hours.

Requirements (must-have):

• 3+ years of commercial experience in JavaScript
• 2+ years of experience with Vue.js (Composition API, Vue Router, Pinia/Vuex)
• Strong knowledge of HTML5, CSS3, adaptive layout
• Experience integrating REST APIs (HTTP, JSON, authorization, error handling)
• Experience working with Git in a team
• Basic knowledge of Docker (running projects in containers)
• Ability to read others' code and work with legacy code
• English: Beginner and above
• Practical experience or clear understanding of the value of working with AI agents
• Conscious code review of AI-generated code: ability to reasonably explain the logic and correctness of the generated result

Bonus points (Nice-to-have):

• Experience with Capacitor, Cordova, or Ionic
• Experience publishing applications in the App Store and Google Play
• TypeScript
• Experience with modern build tools (Vite, Webpack)
• Experience writing unit/e2e tests (Vitest, Jest, Cypress, Playwright)
• Understanding of PWA principles
• Experience with PHP backend (for effective communication with the team)
• Experience in telecom
• Skill in decomposing tasks for effective delegation to AI agents
• Ability to identify characteristic flaws in AI-generated code
• Experience creating system instructions and reusable roles for agents instead of writing one-off prompts
• Ability to build multi-step agent chains (analysis → planning → coding → testing)
• Skill in integrating agents with the external environment: MCP servers, technical documentation, and task trackers
• Clear understanding of the boundaries of AI applicability: where automation is useful and where manual execution is more appropriate
