• Write and maintain comprehensive test cases to ensure code quality, reliability, and maintainability
• Contribute to frontend architectural decisions and participate in design/code reviews to uphold best practices

• Proven ability to analyze and troubleshoot technical issues and deliver effective solutions

• Experience integrating AI-assisted workflows into front-end pipelines — e.g., automating repetitive tasks, code review, or test generation
• Experience writing and maintaining executable specifications and living documentation that stay in sync with code as it changes
• Familiarity with MCP (Model Context Protocol) and connecting AI tooling to internal systems (design tools, issue trackers, component libraries, docs)
• Experience with AI-assisted code review as part of the development workflow

Nice to have

• Experience with Node.js and/or additional programming languages or full-stack development exposure
• Familiarity with state management using Redux and React-Redux, and saga-based side-effect / async flow handling (redux-saga)
• Proficiency with styling solutions such as styled-components
• Experience with testing frameworks such as Jest
• Background in handling multimedia files (e.g., video, audio, image optimization) within the UI
• Exposure to frontend development for networking, mobile, or IoT device interfaces
• Familiarity with visualization libraries or techniques used for topology maps, hierarchical graphs, or interactive layouts
• Experience implementing high-interaction UI behaviors such as zooming, panning, snapping, and node-link editing

• Five weeks of holiday per year
• Flexible work hours and hybrid work model
• Modern office space located in Epicenter in central Stockholm (Hötorget)
