Job Description

Job Description

The Senior Frontend Developer works on our in-house projects: designing features, writing code, performing code reviews, solving problems, and delivering stable, well-built solutions. The Senior Frontend Developer is part of a development team that owns and drives continuous improvement of its business domain using agile methodologies. Within that team they own frontend architecture and are a technical reference point for the frontend. They are expected to show ownership, versatility, and enthusiasm for technical challenges across our stack. They should also set a strong example in using modern development practices, including AI-assisted tooling, to work efficiently and to a high standard.

Key responsibilities

Key responsibilities

  • Designing and developing new frontend features, from requirements analysis through to delivery.
  • Proposing and owning frontend architectural solutions across multiple projects, including component architecture, state management, and shared libraries.
  • Building efficient, testable, and reusable UI components, and promoting consistent patterns and standards across the team.
  • Solving complex performance problems and architectural challenges, with close attention to performance, reliability, and maintainability.
  • Troubleshooting complex application and code issues, and leading root-cause analysis when problems span multiple systems.
  • Integrating REST and GraphQL APIs, and working with backend developers to design and propose new ones where needed.
  • Making effective use of client-side storage solutions.
  • Maintaining, refactoring, and modernizing application features across multiple projects, including legacy code.
  • Conducting analysis of UX/UI projects and application requirements, working closely with other developers, QA, designers and the product team.
  • Providing estimates and technical documentation when requested.
  • Managing individual project priorities, deadlines, and deliverables.
  • Working with external partners when required.
  • Helping track requests, issues, work progress, and other changes using our project management tools.
  • Performing code reviews and coaching and mentoring other frontend developers.
  • Using AI tools thoughtfully to support development, testing, and documentation (e.g. code review assistance, test generation, MCP-based workflows). These tools should enhance sound engineering practice, not replace an understanding of the code, and the role includes guiding the team on how to use them responsibly.
