About us

Crazy fast growth

Zenefits launched in May 2013 at TechCrunch Disrupt. Since last January, our revenue has grown 20x, and our engineering team has grown from 5 to 180. TechCrunch called us one of the fastest-growing SaaS companies ever. Forbes ranked us as the hottest startup of 2014. Even David Sacks, COO of PayPal and founder of Yammer, couldn't resist joining us as COO!

Why all the fuss? Back-office operations for small and medium businesses are broken. Owners are faced with a myriad of time-consuming systems that don't talk to each other. Often, they throw their hands up and use Excel. Zenefits is changing that by providing one system that handles payroll, HR, health insurance, and a lot more for free! That way, our clients can do what they love -- run their business.

Engineering at Zenefits

Here at Zenefits we're trying to redefine the way software is built. From the beginning, we've built our team around the principle that every engineer is the CEO of their own product. Instead of being handed feature requests and requirements from on high, it's each engineer's job to decide what's important for their products, and prioritize accordingly. The product team is our resource, rather than the other way around. We're all full-stack engineers, though of course some projects are more backend- or frontend- intensive.

What do we look for? From stock options to health insurance enrollment, our job is to encode complex business processes and employment regulations in our codebase. Zenefit's engineers need to have a certain savvy about how to deal with these sorts of things. A passion for killing ad-hoc, inefficient spreadsheet workflows also helps.

About our stack: Python/Django on the backend and Ember on the frontend. We don't care that much whether you're familiar with our languages/frameworks; we know that the best engineers pick these up quickly.

Are you ready to be challenged?



Zenefits is home to doers; people with a bias for action and an aversion to the status quo. Together, we're building things that make running a business a whole lot easier.
