Fullstack Developer (m/f/d)

Würth Cloud Services GmbH is a dynamic and rapidly growing startup within the Würth Group. As a spin-off of the global market leader Würth, we combine the best of both worlds: experience and continuity with pioneering spirit and a sense of new beginnings.

Tasks

• Develop, maintain, and scale fullstack features across our modern SaaS platform, working on both React-based microfrontends and serverless backend services.
• Implement responsive, user-friendly interfaces following our design system and ensure seamless integration with backend APIs.
• Design and develop RESTful APIs and event-driven backend logic using AWS technologies (Lambda, API Gateway, EventBridge, etc.).
• Leverage AI tools and agentic AI systems to accelerate development, improve code quality, and automate repetitive tasks.
• Collaborate on shared libraries and packages including UI components, API services, and authentication modules.
• Ensure clean, maintainable, and well-tested code across both frontend (TypeScript) and backend (Python) stacks.
• Work with databases (SQL and NoSQL), focusing on performance, data modeling, and maintainability.
• Write comprehensive unit, integration, and end-to-end tests to ensure high quality and reliability.
• Troubleshoot and resolve issues across the full stack - from frontend behavior to backend performance.
• Participate in code reviews and contribute to architecture and design discussions.
• Optimize applications for performance, scalability, and cost efficiency in a cloud-native environment.
• Contribute to CI/CD pipelines, deployment strategies, and infrastructure-as-code (IaC) practices.

Requirements

• 3+ years of experience in software development with a focus on both frontend (React, TypeScript) and backend (Python, AWS) technologies.
• Passion for building scalable, maintainable, and elegant fullstack applications.
• Self-driven, structured, and eager to adopt emerging technologies, especially in AI-assisted software engineering.
• Strong understanding of modern JavaScript (ES6+) and the React ecosystem (hooks, state management, component-driven design).
• Solid experience with AWS Serverless Architecture (Lambda, API Gateway, CloudFormation/SAM, EventBridge, DynamoDB or Aurora).
• Experience with RESTful API design and integration between frontend and backend services.
• Proficient in database design and querying (SQL; basic familiarity with NoSQL).
• Experienced with testing frameworks (e.g., Jest, React Testing Library, Pytest).
• Familiar with Git and modern development workflows.
• Understanding of responsive design principles, UI/UX best practices, and component-based architectures.
• Practical experience using AI-assisted development tools and agentic AI workflows to enhance productivity, automate repetitive coding tasks, or assist in testing, documentation, and debugging.
• Experience with CI/CD pipelines, Docker, and infrastructure-as-code.
• Knowledge of authentication flows (OAuth2) and microfrontend patterns (Module Federation) is a plus.
• Familiarity with Material-UI, Storybook, code quality tools (e.g., SonarCloud), or monorepo management (e.g., Turborepo) is advantageous.
