Staff Software Engineer (Python)

Staff Software Engineer (Python)We are looking for a Staff Software Engineer (Python) to join a cybersecurity company building products that keep Linux systems secure and supported. Its software helps organizations running Linux infrastructure stay protected against known vulnerabilities, and continues to support operating systems and tools that have passed their standard maintenance period.
