Hi leaders, Do you generally have a rule of thumb of when you hire SREs/ engineers with more domain knowledge in your platform teams vs genaralists/ distributed systems engineers ? The question I have is when would you hire an SRE for say data platform if you've got mostly or all managed softwares.

People can spend a ton of money on managed software if they aren’t looking for optimization opportunities - implementing those can take time and expertise. Could bed worth the trade to bring in an SRE/platform person into a data area if they bring observability, troubleshooting, and optimization to the table

Thanks. Would the expectation from the SRE be to weigh the pros and cons of adopting self managed vs managed software?
