Lead React Engineer (JavaScript/TypeScript)

Our client is among the leaders in creating traffic management systems. We are looking for a Technical Front-End Leader who will help to develop a common HMI and API layer that covers roadside products (Measurement systems):

- HMI / API architecture, which is reusable on other platforms with "minor" adaptations and extensions.

- The User-Interface should be harmonized in a recognizable style to align usability and workflows.

- The User-Interface (HMI) should be web-based, touch-friendly, and have a modern look and feel.

- Scalable client performance regarding bandwidth throttling product's configurability makes it suitable for a wide range of application types and measurement systems

- Modularity and con to cover multiple measurement systems with its requirements.

The Lead Front-End will provide the technical vision and guidance for the front-end development team. They make key architectural decisions related to the React application, oversee code quality, and often contribute significantly to the more complex development tasks. Will also be involved in the initial setup and configuration of the React project and its integration with the GraphQL API.

Key Skills:

• Expertise in React and JavaScript/TypeScript: Thorough understanding of React fundamentals (components, state management, hooks, routing), JavaScript best practices, and modern front-end development patterns.
• Experiences with Frameworks: Control Set Libraries (DevExtreme)
• Front-End Architecture and Design: Ability to design maintainable front-end components to reuse in different contexts and product lines.
• GraphQL Proficiency: Understanding of GraphQL concepts (schemas, queries, mutations, subscriptions), experience integrating with GraphQL APIs, and knowledge of GraphQL client libraries (e.g., Apollo Client, Relay).
• Testing Frameworks: Experience with unit testing, integration testing (e.g., React Testing Library, Selenium), and end-to-end testing.
• Build Tools and Pipelines: Familiarity with build tools (Gitlab, Jenkins), and experience with CI/CD pipelines.
• Version Control (Git): Expertise in using Git for collaboration and version management.
• Code Quality and Best Practices: Enforcing coding standards, conducting code reviews, and promoting best practices within the team.
• Problem-Solving and Debugging: Excellent analytical and debugging skills.
• Leadership and Responsibility: Ability to guide other developers on the team.
• Experience with backend and experiences in data transfers, especially bigger payloads (video-streams or 3d Visualization of PointCloud-Data.)

Core tasks:

• Technical Architecture and Design: Define the overall front-end architecture for the React application, make key technical decisions, and ensure scalability and maintainability.
• Technical Solution Design: Support Requirements engineering and propose a solution design for stakeholders.
• GraphQL Integration Strategy: Define the approach for integrating with the new GraphQL API, including client library selection, data fetching patterns, and error handling.
• Code Quality and Standards: Establish and enforce coding standards, conduct code reviews, and promote best practices within the development team.
• Development and Problem Solving: Lead the development of features, troubleshoot technical issues, and provide technical guidance to the team and stakeholders.
• Performance Optimization: Identify and implement optimizations to improve the performance and responsiveness of the React application.
