We did some research for a job search engine we just launched. For mid-level positions, here is what we found:
- Google: $6k - $12k
- Facebook: $7k - $12k
- Grab: $5k - $8k
Amazon doesn't seem to be hiring software engineers in Singapore. They are hiring solutions architects though but it wouldn't be fair to compare solutions architect and software engineer salaries.
The job search engine we built is called CareerWiz and there are 300+ software engineer job listings for Singapore with salary information:
