Junior Trainees

Junior trainees help our firm’s employees in a wide range of tasks as part of a tight-knit trainee team. Our junior trainee programme is open to law students in the early stages of their studies and provides a window into the daily routines of our firm and an opportunity to develop organisational and team-work skills.

Knowledge Management Trainees

When you are at least halfway through your legal studies, you can apply for a trainee position in our Knowledge Management team. KM trainees are the detectives, researchers and analysts of our firm. They find the right information and background material to support our firm’s lawyers in their assignments.

Legal Tech Trainees

Are you eager to see and experience how technology can be harnessed in legal work? Our legal tech trainees are responsible for using and supporting our personnel in the use of legal technology tools.

Senior Trainees

When you're on the home stretch in your studies, we can offer you practical experience of working as a lawyer in our senior trainee programme. Senior trainees assist our lawyers, and their job description is very close to that of a freshly graduated lawyer.

Trainee Assistants

Our trainee assistants either work directly with our lawyers or act as an extra pair of hands for our full-time assistants in various administrative and client project tasks. This position is ideal for the work-practice component of a BBA.

Business Services Trainees

Our business services traineeships offer you a behind-the-scenes view into the support functions of a major law firm and their vital role in assisting the work of our experts. We regularly employ trainees in HR, ICT, library services, communications and marketing, risk management and finance. In addition, we hire catering assistants to support our conference services.

The most important characteristics for a lawyer are curiosity and the desire to learn new things. Every assignment is an opportunity to learn.
