Lead Full Stack with passion for Frontend

Improve People Performance with Data-driven management

Join and build excellent software! - We are great at what we do but need you to pitch in with your skills and effort to grow and become an even better team.

For more than 30 years, Master International A/S has developed high-end HR test tools. The tools are used for both recruitment and team development.

Master International A/S focuses on development. They build and modernize their tests, solutions, and software in-house and have a network of Partners taking care of sales, support, and consultancies.

They are currently on a fast and exciting journey where they are expanding to new markets and regions. Perhaps you have never heard of Master, but we create psychological assessment software used daily by HR departments and Recruitment Consultants in more than 20 countries, and thousands of people are being tested by solutions every week.

The Project….

The platform consists of a suite of applications and tools used by the customers, their employees and candidates, external system vendors, our partners, and our colleagues.

The backend is implemented in .NET Framework and hosted on Azure. It provides core functionality for their psychologists to develop and maintains test solutions based on psychometric theories and data analytics.

It also serves the customer applications and integrations via an open API. The applications currently consist of Windows Applications build in WPF and Web Apps build in ASP.NET MVC.

They are transitioning towards a CQRS-architecture build using .NET (core) with an Application API (WebAPI) that supports multiple Apps. The current tools, windows applications, and Web Apps will be replaced by new web applications and (perhaps) native apps. Master wants to bring their products and solutions to all types of devices.
