Just looking at annual pay, lets say you pay devs a reasonable 75K USD in Chattanooga. Thats 56 Lakh INR annual pay in India. You can get a top engineer for that kind of pay.

This doesn't even account for the difficulty in hiring an engineer of the same caliber in Chattanooga and all the associated overhead like health insurance, etc.. which are much lower in India.

If you already have experience building a high quality engineering team in India (thus know how to overcome cultural barriers), its pretty much a no-brainer.
