Summary:

As a Senior Frontend Developer, you will join the team to develop and scale two core production applications used across multiple manufacturing sites worldwide:

• a native iOS app

• a Progressive Web App (PWA)

  
  

The role covers product development for both apps: delivering new features, modernisation, and strengthening quality, reliability, and usability.

You’ll work in a Scrum/Agile setup closely with a Product Owner, UX/UI Designer, Backend Developers, and a Data Engineer.

Main Responsibilities:

As a Senior Frontend Developer, you will be responsible for designing and implementing robust front-end solutions. Your core duties will include:

• Deliver complete features for both the iOS app and the PWA with a strong focus on performance, accessibility and usability.

• Integrate with complex RESTful APIs backed by a .NET/C# Azure backend and collaborate closely with backend engineers on API design.

• Implement UI testing strategies (unit and integration) using tools like Vitest and Playwright.

• Work with Tailwind CSS and design systems to build consistent, themeable UI components.

• Contribute to code reviews, mentor colleagues and participate in architectural decisions for the frontend.

• Support CI/CD practices (GitHub Actions preferred) to ensure automated testing and reliable deployments for both apps.

• Incorporate secure development practices and contribute to observability and performance monitoring for client apps.

• Collaborate closely with Product Owner, UX/UI Designer, Backend Developers and Data Engineer in an agile environment.

  
  

Key Requirements:

• Strong experience with Vue.js 3 (or similar modern SPA frameworks).

• Excellent JavaScript and TypeScript skills (TypeScript 4+).

• Proven experience integrating with complex RESTful APIs and handling asynchronous/real-time scenarios.

• Experience with Tailwind CSS and working with design systems.

• Strong communication skills and fluent English, written and spoken.

Nice to Have:

• Experience with Ionic (or other hybrid/mobile frameworks) and a strong understanding of mobile UI patterns.

• Knowledge of secure development practices and domain‑driven design.

• A collaborative mindset and the willingness to share knowledge and mentor others.
