Job description

We're looking for passionate and skilled software engineers to enhance our software development team that is responsible for building the cross-platform software framework and core technologies upon which Capture One is built, as well as the applications of our industrial partners.
This cross-platform framework is written in C++ and runs on Microsoft Windows, Apple macOS, Linux, and within our own embedded operating system. Consisting of a few million lines of code, it uses multi-threading, vectorization, and GPU processing for performance. The key components of the foundation software are libraries for reading and writing of various image file formats, a highly optimized image processing pipeline, a library for communicating with different camera systems, Capture One’s extensive document object model and data storage system, as well as several other cross-platform support libraries.
The team develops new features and functionality but also refactors existing code for improved encapsulation, performance and maintainability. One of the team's tasks is to convert existing C# and Objective C code to cross-platform C++. If you love developing well-written software libraries, refactoring technical debt, and using the latest modern C++ practices, as well as working on technically challenging projects, then you will be a good fit for our foundation team.
In your cover letter, please tell us why you'd be a good match for our team and what your key assets are as a software developer.
