Description

CloudLinux is a global remote-first company. We are driven by our principles: do the right thing, employees first, we are remote first, and we deliver high volume, low-cost Linux infrastructure and security products that help companies to increase the efficiency of their operations. Every person on our team supports each other and does what we can to ensure we all are successful. 

TuxCare is a subsidiary of CloudLinux. It offers a portfolio of security solutions for Linux and open-source software aimed at enterprise organizations. With TuxCare, enterprises can automate live vulnerability patching, minimize downtime, keep their applications secure and compliant, and get support from a team that knows Linux security best – covering the most popular Linux distributions, end-of-life systems, programming languages, and much more.

Endless Lifecycle Support (ELS) enables organizations to continue securely using Linux distributions and software languages that have reached the end of life or no longer receive standard security support – delivering vulnerability patches for unsupported versions of CentOS, CentOS Stream, Ubuntu, Debian, Oracle Linux, PHP, Python, and Spring software development framework.

We are looking for a Senior Software Engineer to join our team and contribute to the development and maintenance of our Windows-based projects. In this role, you will be responsible for building, modifying, and maintaining .NET (C#/.NET) applications on Windows, ensuring their stability and performance.
