I don't have specific salary data for a Meta level 5 software engineer at the moment. However, based on general industry standards, software engineers at similar levels in major tech companies typically earn between $120K and $180K in base salary, with additional compensation such as bonuses and stock options.
For a more accurate figure, I recommend researching further on platforms like Glassdoor or reaching out to current employees for insights on compensation packages at Meta. If you're looking for salary data for a different role or company, let me know!
