Questions about joining our team?

remote/office work

We are a fully remote company, but we value in-person connections. We host annual trips for the entire team to collaborate and bond, and some teams organize additional meetups throughout the year to work together.

what does "flexible work" mean at KIS?

You can choose your work hours, as long as you meet your team and client's main meetings, cerimonies and deliveries. Apart from those ceremonies, you can choose how to distribute the remaining hours of your day. Just make sure you're communicating frequently and clearly.

how we keep our teams together

We have performance plans, feedback and follow-up sessions, social gatherings (online and offline) and laid-back events to keep the teams engaged and united.

how does our contract work?

Our contracts are based on Legal Person agreements (PJ in Brazil). Let us know if you need help explaining this contract model.
