On average, backend developers make either https://www.glassdoor.com/Salaries/backend-developer-salary-SRCH_KO0,17.htm, https://www.indeed.com/career/back-end-developer/salaries, or https://www.salary.com/research/salary/recruiting/back-end-developer-salary#:~:text=The%20average%20Back%20End%20Developer,have%20spent%20in%20your%20profession. StackOverflow uses medians instead, and their https://survey.stackoverflow.co/2022/#salary-united-states suggests the backend developers actually make upwards of $150,000 per year.
Backend developers have a high salary (whether it’s $80k or $150k!), solid career prospects, and unshakeable job security because backend developers are in very high demand by very well-funded companies.
To compare these roles to how much backend developers make, I’ll use the same source for every job: Indeed’s average salary estimate.
The average salary for data scientists is a bit higher than backend developers, clocking in at $100k per year https://www.indeed.com/career/data-scientist/salaries#salary-satisfaction to Indeed.
