Cornerstone Technologies is a community of engineers driven by making a better world through lines of code. We believe that technology is here to help us live easier and happier lives, and we want to play a role in building this future.

Our staff are our core competitive advantage. While almost anything in this world can be imitated, the one thing that can’t be copied is the culture. We put accent on work-life balance, flexibility and opportunity to grow.

Our vision is for everyone to live a better life, regardless of their geo-location. When everyone has access to information — and learn from — the impact of their work, they are poised to make better decisions and be happier.

You don’t have to wait for a better world. You can join us and build it.
