• You will drive tangible outcomes by taking ownership of incidents when they arise, leading thorough post-mortems to identify root causes, and implementing continuous improvement initiatives based on lessons learned.
• This role offers the chance to work on challenging and interesting projects within a dynamic and fast-paced environment, contributing directly to the security and longevity of critical open-source software used by enterprise organizations worldwide.
• You will be instrumental in ensuring that TuxCare's ELS product remains a leading solution, providing essential security patches and support for software that would otherwise be unsupported, thereby mitigating significant risks for our clients.
• The position demands a proactive and self-driven individual who can thrive in a startup-like atmosphere, taking end-to-end responsibility for the tools and services they develop.
