Our Purpose

Impact

We could have chosen easier jobs at larger companies, but it’s too easy to get lost in a big organization. Even worse, we could waste our time doing things that don’t matter for bosses who don’t understand. At Sera4, everyone’s impact can be felt. It’s important that everyone is connected to the impact they make, whether that be to the results of the company or to the change that our solutions make in the world.

Experience

A small company offers a healthy selection of challenges across broad domains. Employees have the opportunity to engage with any of them. We often hear that employees learn more in a few months at Sera4 than they did in a few years at a larger company. For our technical developers, we are working on some of the most cutting-edge technologies. One of the few iron-clad promises we give to people who join us is that you won’t be bored.

Flexibility

We consider our time in thirds: a third for sleeping, a third for working, and a third for everything else. We support all of these parts, and we give all employees the freedom to strike their own balance. We celebrate results, not office hours. That’s why we don’t host catered dinners designed to keep you late into the evening. We want you to also spend time with friends, family, and hobbies.
