Senior Frontend Engineer/Frontend Lead

A reputable software company that harnesses the power of AI voice automation to supercharge customer experiences is hiring a Senior Frontend Engineer/Frontend Lead. With AI voice assistants, your call center can make quality human-like calls at lightning speeds, collecting and analyzing data automatically to reach and activate more customers. This helps call centers reduce costs by automating repetitive tasks and lowering agent workload. This frees up agents to focus on things only humans can do. Over the long term, the company aims to rethink the future of business communication.

The KL R&D Center is our core overseas engineering hub, responsible for building and iterating our product and technology stack locally. We are looking for a Senior Frontend Engineer/Frontend Lead to join and help lead the KL engineering team. This role combines hands-on technical leadership with team management, serving as the technical backbone of the local R&D center. You will drive architecture decisions, own the technical roadmap for key systems, and mentor a growing engineering team — while still writing and reviewing production code daily.

Responsibilities

Technical Leadership
• Own the frontend architecture for our SaaS platform and operations management systems; make technology selection and framework upgrade decisions.
• Design and implement complex frontend features with a focus on performance, accessibility, and maintainability.
• Build and maintain reusable component libraries and design systems to ensure UI consistency across products.
• Establish frontend engineering best practices: code review standards, build tooling, testing strategies (unit / E2E), CI/CD integration, and performance monitoring.
• Collaborate with backend teams on API design and data contract definition to ensure efficient frontend-backend integration.
• Explore and integrate AI/LLM capabilities into frontend products, such as conversational UIs, real-time data visualization, and intelligent interaction patterns.

Team Management
• Mentor and guide junior frontend engineers, conducting code reviews and fostering a culture of quality and continuous improvement.
• Coordinate frontend development tasks: sprint planning, workload distribution, and delivery tracking.
• Serve as the frontend communication bridge between KL R&D center and headquarters (Shanghai), aligning on product requirements, UI specifications, and release schedules.

• Strong experience with modern frontend tooling: Vite/Webpack, ESLint, Git workflows, and automated testing frameworks (Jest, Cypress, or Playwright).
• Proven ability to architect frontend applications: state management, routing, modular design, and micro-frontend patterns when appropriate.
• 1+ years of team lead or mentoring experience; comfortable owning code quality standards and guiding other engineers’ technical growth.
• Proficiency in English — able to participate in technical discussions, write documentation, and communicate with both local and overseas teams. Added advantage if able to converse in Chinese as collaboration is expected with China-based teams.
• Strong sense of UI/UX quality, attention to detail, and user empathy.

Preferred
• Experience with React or other major frontend frameworks in addition to Vue; ability to evaluate and migrate between frameworks when needed.
• Experience building data visualization dashboards or real-time monitoring UIs (ECharts, D3.js, etc.).
• Familiarity with backend development (Node.js, Golang, or Python); ability to understand and debug full-stack issues.
• Experience with AI/LLM-powered UI features, such as chatbot interfaces, streaming response rendering, or prompt-based interaction design.
• Experience working in cross-cultural, distributed teams (especially China + Southeast Asia collaboration).
• Experience with mobile-responsive design or hybrid app development (e.g., uni-app, Electron).
