Your mission will be challenging but interesting: to develop a sophisticated end-to-end system, and drive adoption of modern methodologies like Scrum, TDD, and Continuous Integration within the team.

Description
We work primarily with big enterprise companies, helping them to replatform their client-facing web applications to the modern technological stack, or build web applications for internal use. In most cases we work with modern frameworks and tools, like Angular or ReactJS. We also use NodeJS to build back-end for the front-end. In addition, we do performance optimization and architecture assessment. Solutions we use are based on strong engineering practices, and our company follows the best DevOps and automation practices.

You can get a unique experience working with a complex customer’s infrastructure and dealing with a high number of integrations with external systems, as these require strong architectural design skills.

If you are excited about all aspects of modern engineering - writing great code, creating architectures, designing components, interacting with clients, and delivering the working system to production - then you are the kind of person we are looking for. If you enjoy freedom and responsibility, creative thinking, leading, and mentoring others, come join our team of world-class developers, QA engineers, DevOps engineers, architects, and managers.
