Position Description

As a Desktop Application Developer, you’ll be working on various desktop applications that we’ve developed; one of these applications is Top Tracker - the most innovative and flexible time-tracking software in the world.

We use C++ as our main language for creating desktop applications. While being powerful and flexible, it allows us to control the applications at the deepest level possible. We’re looking for talented C++ developers to further improve and enhance our desktop products.

We’re aiming to support as many different platforms (OS X, Windows & GNU/Linux) as possible, so most of the code we write is cross-platform. Because of this, we use various platform-agnostic frameworks in our work. The one we use most extensively is Qt. Not only does it allow us to create beautiful and responsive GUI but it also makes it much easier to write portable system-interacting code with minimal effort.

Our desktop team spans the full stack of development, from digging into system API calls to perfecting the GUI.

We don’t cut corners, and we don’t make compromises—we create beautifully architected desktop apps that are polished, fast, well-tested, and a joy to use.

This is a remote position that can be done from anywhere.


  • Build cross-platform desktop client features and infrastructure.
  • Full life cycle development of software products.
  • Identify bottlenecks and bugs and devise elegant solutions.
  • Making strategic technical decisions related to new products and functionalities.
  • Onboarding and mentoring new team members.


  • You must have a solid grasp of object-oriented programming, automated software testing, databases, development, and testing methodologies.
  • Background in cross-platform application development.
  • Solid understanding of Qt 5.
  • Good in desktop development on, at least, one of the following platforms: Windows 7+, OS X 10.8+, Linux (Ubuntu 12.04+, Fedora 22+) and deep knowledge of underlying native API (WinAPI, Cocoa/Carbon, X11, GTK).
  • Great experience with, at least, one of the most common compiler toolsets (GCC, CLang, Visual C) is a must.
  • Substantial experience in C++11/14.
  • Ability to come up with simple solutions without hacking and overcomplicating.
  • Take smart risks and champion new ideas.
  • Be comfortable with iterative and incremental development.
  • Be willing to help your teammates, share your knowledge with them, and learn from them
  • Be open to receiving feedback.
  • You must be a world-class individual contributor to thrive at Toptal. You will not be here just to tell other people what to do.
