If you’ve ever wondered which languages that developers used to build multi-billion dollar startups like WeWork, Juul, Airbnb and SpaceX, look no further.
Coding Dojo, a coding bootcamp that trains developers and helps place them in programming roles, looked at full-time job postings from the job listing site Indeed and the developer tool website StackShare to see what languages the billion-dollar plus “unicorn” startups were using to build their technology.
One of the top languages Coding Dojo sees growing strong amid the unicorns is Python.
Donovan An, director of West Coast Campus Operations at Coding Dojo, says this is because Python is a general purpose language that can be used for games and web development. But what has really make it gain popularity over the past five years is the explosion of data science and machine learning in Silicon Valley.
An also says he was surprised by the popularity of newer languages like Kotlin and Go. Kotlin is the fastest growing programming language according to GitHub, and it’s most often used to develop Android apps. Go is a language that was developed by Google – an association that may have given it a leg up, An says.
Overall, An says companies aren’t looking for developers who know one specific language.
“It’s important for these engineers to have a wide tool set,” An said. “What these companies are looking for in terms of is not a developer who knows Java or Golang or Kotlin. They are looking for developers who are self-sufficient and critical thinkers, not married to one language. They are looking for someone who can come in and problem solve.”
Here are the technologies that top startups are using to build their systems, according to Coding Dojo data:
