About the role

In this role, you will engineer and develop the backend that will serve 10s of millions of users. There is no legacy codebase which means you don’t need to suffer from old poorly-written code, you need to write clean code from scratch. As one of the first engineers in the company, you will be responsible for ensuring the code style is implemented consistently across the codebase right from the start. Keeping the code modular and easy to read is one of the top priorities. At the same time, as a growing startup, we are moving at a fast pace, so you need to be agile and focus on delivering software that does the job first and then improve it step by step. You will work directly with the founding team.

  • Be on top of all most recent code practices, libraries and frameworks and push the team to use better tools

  • Conduct thoughtful code reviews for your team members

Basic qualifications
