What We're Looking ForThe ideal candidate is a proactive, technically strong engineer who can take ownership of automation initiatives and deliver practical solutions with minimal supervision.
You should be comfortable working directly with Linux infrastructure, writing and troubleshooting scripts, integrating monitoring tools, and identifying opportunities to eliminate manual processes.
This is not a cloud-focused DevOps or application deployment role. We are specifically looking for deep Linux systems expertise combined with strong infrastructure automation and performance monitoring experience.
If you enjoy solving infrastructure challenges through automation and want to make a tangible impact within a collaborative technical team, we'd love to hear from you.
All applications are reviewed by our recruitment team, and hiring decisions are made by people. We may also use AI-enabled tools to support parts of the application review process.
