• Own features from start to end. Get to shape the feature while collaborating with other team members across the organization and actively contribute towards providing a great UI/UX to enterprise manufacturing companies
• Maintain and extend frontend codebase, keep the UI/UX code consistent across the application, avoiding technical debt and adhering to security best practices

• Interest in being challenged by developing a scalable web app with a strong UX focus to deliver process insights to our customers based on big data

• Excellent communication skills in English, in particular the ability to explain complex topics
