Initial 2 months, extension very likely
Projekt może zakończyć się po 2 miesiącach, a przedłużenie nie jest gwarantowane, mimo że jest prawdopodobne.

Small, experienced team with a clear technical direction
Zespół może być mały, co oznacza potencjalnie większą odpowiedzialność i mniejszą możliwość delegowania zadań.

Access to learning and training platforms
Dostęp do platform może być ograniczony lub wymagać dodatkowych zgód, a niekoniecznie oznacza dedykowany czas na naukę.
🟡
Competitive hourly rate: PLN 120–160
