Knowledge of design patterns and programming principles
On a senior level we expect programmers to know design patterns and programming principles related to frontend and computer science itself. We believe that using such patterns decreases cognitive complexity when code is read and discussed.

Understanding of functional programming
We expect you to understand FP and FRP and know when to use each paradigm. You should know when OOP doesn’t work, but also when it’s more accurate than FP.

Ability to design high level architecture of frontend applications
As a senior developer you will be thinking in every layer of application, including high level architecture. You should be able to evaluate and propose different approaches, create POCs and write documentation.

Experience with GIT and Git Flow
We use GIT as a version control system, so you should be fluent with it. Also you should know git workflows like Git Flow.

Experience in agile development
We aim to use scrum methodology if possible, but for sure we have agile mindsets. You should know how to deliver business value in an incremental way

Experience in estimating projects and features
As a senior developer you should be able to estimate requirements on scrum plannings, but also do high level estimations on projects.

Will to claim the ownership of required tasks
As a senior developer you should take responsibility for tasks we need to develop for our clients. We work as a team, but we expect you to take ownership and deliver without supervision.

Will to mentor and lead other developers
We expect senior developers to guide less experienced ones. It’s also possible you will lead the frontend part in your project.

Experience in working with a clients
Gathering requirements both during workshops and on day-to-day work is one of responsibilities of all members of the scrum team but we especially count on the most experienced ones.

Remote work 1 day a week
