PAID INTERNSHIP WITH FURTHER PROGRESSING TO JUNIOR FULL STACK ROLE

The goal is to find developers who have basic coding skills but are at the beginning of their careers. Recent graduates (or students finishing their final coursework) in Computer Science or STEM (Science, Technology, Engineering, and Mathematics) are appropriate candidates. We are also open to working with developers who have meaningful coding experience but no formal degree in Computer Science or STEM.

Participants are expected to know how to code and to know the basics of web development. Familiarity with Javascript plus any one of PHP, Java, Python, C#, Ruby, Rust, Elixir, or C/C++ is required. We will use git (Gitlab), YouTrack, and xWiki extensively, but will train participants (at a fast pace) on all of these tools. Meaningful participation in open-source projects is a huge plus, but not expected.

Candidates must be proficient English readers and speakers, equivalent to a C1 or higher on the British Council scale. Test certifications are appreciated, but language skills will be verified independently by Academy instructors prior to accepting candidates into the program.

THE PROCESS

1. Interns will complete a three-month academy followed by a one-month "reading period" during which they must pass certain full-stack certification exams.

Coursework will be partially synchronous, and students will need to be available for lectures or team activities between 12 PM and 4 PM GMT+1 time. (Exact schedule TBD.) Please note this is considered a full-time position. In the prior cohort, we observed that students who were still taking university courses or had a job in addition to the program were less likely to complete the program than those that were able to dedicate more time and energy to the program.

2. After successful completion, they will interview for four-month internship positions on company teams.

3. At the end of the four-month internship, teams may choose to convert their interns into junior developers, with the appropriate salary increase.

This cohort’s focus will be full-stack development using PHP/Laravel for the back-end, Angular for the front-end, and Postgres as the RDBMS. We will also cover theory and practice of coding with agentic AI assistants, since this is fast becoming a must-have skill for developers of all experience levels.

Please apply with your full CV.

Thank you!
