What is Scaler Academy

Many engineers (like us!) enter software engineering almost by mistake, are exposed to ‘old’ teaching methods and are taught to ‘cram’ content. This creates gaps in an engineer’s CS learning, makes them under confident and prevents them from accelerating in their career. 

Scaler Academy is tailor-made for engineers to master the foundations of CS (DSA & System Design) and to take their career to the next level, via: 
  • A structured, guided and industry vetted curriculum
  • Live classes by faculty who have been there, done that
  • Regular 1:1 mentorship from industry veterans 
  • Practical experience through real-life projects
  • Career support via a dedicated recruitment team, alumni network, etc.
  • Aspirational peer group of 3,500+ Scaler students & alumni
  • NEW! We've introduced 3 new electives - Advanced DSA, Concurrent Programming, and Product Management to help you further accelerate your tech career. These will be taught at the end of the course, and are completely optional. However, they provide deep insight into crucial topics, and hence, we strongly advise you to opt for them!

 The curriculum is designed to make you a solid engineer. Find out more about us at
