• Architecture & Integration: Engineer scalable frontend/backend solutions, ensuring seamless integration between React components and .NET services.
• Testing & Quality: Write unit, integration, and functional tests using modern testing frameworks (Vitest/Jest-compatible, Playwright) and React Testing Library to ensure reliability and performance.
• Collaboration: Work closely with product, design, and engineering teams to refine requirements, participate in code reviews, and contribute to sprint planning.
• Documentation & Best Practices: Create clear technical documentation, enforce coding standards, and mentor team members on best practices.
• Agile Delivery: Track progress via Jira or Kanban, estimate effort, and deliver projects on time in a fast-paced, iterative environment.

What do you need to succeed?

• 5+ years of experience in React (with Material UI) and .NET Core (C#, MVC, REST/SOAP APIs).
• Strong proficiency in TypeScript, HTML, CSS, and frontend build tools (Webpack, npm).

• Expertise in unit/integration testing and CI/CD pipelines.
• Ability to design scalable frontend/backend architectures and integrate APIs.
