Who We Are

The idea was sparked from the clumsy paper flashcards that Alec Whitters, Co-Founder and CEO, and his peers were using to study for their dental boards. Wouldn’t it be better, he thought, to use our mobile phones to study? When he couldn't find an effective mobile learning solution, he decided to create it. HLT was born. Since its start in 2012, HLT has attracted millions of learners and we’re determined to support their desire to keep learning as part of their practice.

We hold tightly to our core values to innovate, captivate, and educate. These ideals are the heartbeat of our company and we are rigorous in finding coworkers who share these qualities.


Who We Are Looking For

Over 1 billion practice questions answered. Nearly 500,000 active monthly users. We are growing again and it’s time to add to our team. We are looking to work with the best, someone who learns from us as much as we learn from them. We are looking for someone bright with a proven track record in developing software for high quality, scalable applications. Someone we'll be proud to say is part of our team and who will play a large role in pushing HLT forward. As an engineer at HLT you will be responsible for the API that powers all our applications.
