Senior Frontend Developer

Starting salary: €3,500–€5,000

We are looking for a new colleague to join our growing team. You'll be helping us build new features as well as define the technical and architectural direction for our app and its user interface.

This job is for a developer who gets excited about turning ideas into reliable and clear code, thrives on iterative development cycles, and enjoys collaborating with other developers.

You'll work on things like

• Frontend development of the Sufio application.
• Development of supporting applications for marketing and content management (Wagtail CMS).
• Working closely with our designers and technical writers to design and develop a great-looking, consistent, and intuitive user interface.

Requirements for the role

• Great experience with React for web
• Redux, TypeScript
• Npm/Yarn, Webpack bundler (or similar)
• Experience with development of web applications (HTML5, CSS3, Sass, JavaScript and jQuery)
• Some experience with Python and Python-based web frameworks like Django or Flash
• Git, Docker
• Passion for learning new things

Nice to have

• Tailwind CSS framework
• SQL and relational databases (PostgreSQL)
• Experience with UX and UI design

For easy project management and communication we use Jira and Slack. We’re not wasting time on endless meetings and we set reasonable deadlines for our tasks. We work in an open and easygoing atmosphere. Our work is challenging enough and we're always striving to move forward so you’re definitely not going to be bored. 

The backend of our app runs in Python 3.8 and uses the Django 3 web framework.

Our frontend uses React combined with the Redux framework for state management, while some parts of the app are built in HTML5 using jQuery. Our new UI kit helps us to achieve a consistent look of our UI across the entire app, with all UI elements defined in the Tailwind CSS framework.

Our applications are fully Dockerized, managed via Kubernetes and running in the Google Cloud Platform. We use Redis to store our cache and Celery queues state for background processing of tasks. Our main database is PostgreSQL, complemented by MongoDB for storage of our logs.

We manage our source code using Git and access it through GitLab. We use Gitlab CI to manage our continuous integration process including deployment to the cloud. To run and analyze our automated test suite, we use py.test test runner. To keep the code consistent, Black, Flake8 and Mypy ensure our internal code quality and style are in place. Documentation is managed and built using Sphinx, partially auto-generated from the code. In production, Rollbar helps us with tracking errors and performance metrics.

All the technologies we use are open source and we frequently contribute to various projects. We use mainly Python but we’re experimenting with some of the newest technologies such as Go.
