Linux Systems uplifting migration from RedHat 6 to 8 version

Migration from RedHat 6 to 8 version.

We're looking for a jack of all trades.

A well-rounded engineer who can quickly perform the job. The job requires shifting working software, where is no active development planned, from one OS to another OS.

It might require coding as OS specifics might change, but the main job is to plan and execute the move in a risk-free manner (it is a trading environment).

It requires gathering the knowledge scattered throughout the organization, creating a plan, identifying stakeholders, executing tests, executing and monitoring the shift, and reacting to production issues.

It is a mix of DevOps/SRE with a C++ developer, with good communication skills.

The suitable candidate should be able to:

• Discover and explain the existing architecture to determine the impact radius of the upgrade work and releases.
• Navigate log files and read code to debug the deployment, figure out the correct configuration, etc.
• Come up with a migration plan for the system to a newer version, considering rollback, downtime, failover, etc.
• Work on a system that has no one expert and piece information by talking to various people with disconnected expertise.
• Comfortably work on Unix systems and ideally, read C++ code.
