Turing connects exceptionally talented software developers to remote engineering jobs at Silicon Valley and US-based companies. 200+ companies, including those backed by Google Ventures, Andreessen Horowitz, Founders Fund, Kleiner Perkins, and Bloomberg, have successfully hired Turing developers.

- Turing offers a wide range of long-term, full-time remote jobs for Full Stack, Front-End, Back-End, Mobile, DevOps, and AI/ML developers.
- Turing remote developers enjoy higher pay than local standards in most countries, a healthy work-life balance, a strong sense of community, and rapid career growth.

Turing is backed by well-known investors like WestBridge Capital, Foundation Capital, Facebook’s first CTO (Adam D’Angelo), executives from Google, Facebook, Amazon, Twitter, and Founders Fund (investors in Facebook, Tesla, Asana, etc.), among others. The company is led by serial AI entrepreneurs Jonathan Siddharth and Vijay Krishnan, whose previous firm leveraged remote talent and was successfully acquired.

The company was founded in 2018 and is headquartered in Palo Alto, California.
