As a Design Engineer, you will need to master following:

• engineering processes
• interpret technical requirements
• project management

More generally, a design engineer is also versed in:

• CAD software
• assess financial viability
• circular economy
• define technical requirements
• design principles
• engineering principles
• execute analytical mathematical calculations
• execute feasibility study
• manage engineering project
• mathematics
• perform scientific research
• present artistic design proposals
• technical drawings
• use technical drawing software

It also helps to know the following:

• adapt to new design materials
• design power plant systems
• keep up with digital transformation of industrial processes
• nuclear physics
• thermohydraulics
• CAE software
• adjust engineering designs
• analyse stress resistance of materials
• analyse stress resistance of products
• analyse test data
• build a product's physical model
• conduct performance tests
• conduct research on trends in design
• create a product's virtual model
• create technical plans
• design prototypes
• determine suitability of materials
• develop test procedures
• draft design specifications
• draw design sketches
• liaise with engineers
• manufacturing processes
• model based system engineering
• perform test run
• prepare production prototypes
• product data management
• record test data
• supervise work on design planning
• use CAD software
