Understanding of security tools and practices , such as multi-factor authentication, data encryption, etc.

Previous experience supporting IS Operations or enterprise platforms

What We're Looking For

A self-starter who takes ownership of systems and delivers results independently

A problem-solver who thrives in lean teams with hands-on responsibilities

Someone who values clarity and documentation

A strong communicator who collaborates well with both technical and non-technical stakeholders

This is an opportunity to join a technically challenging project environment with the freedom to own infrastructure and influence systems from the ground up. If you're an engineer who enjoys solving deep platform-level challenges and working across Linux systems and networks, this is the role for you.
