🔍 Dekoder Ogłoszenia
🔴
Expert Java Engineer
Może oznaczać zarówno doświadczonego specjalistę, jak i kogoś, kto ma po prostu szerokie, ale niekoniecznie głębokie doświadczenie w Javie.
🔴
mission-critical financial systems
Systemy te często wymagają bardzo wysokiej stabilności, co może oznaczać pracę pod presją i konieczność reagowania na awarie w trybie 24/7.
🔴
influencing architecture
Może oznaczać rzeczywisty wpływ na architekturę lub jedynie udział w dyskusjach, gdzie ostateczna decyzja należy do innych.
🔴
6–8 office visits per month
W praktyce może oznaczać częstsze wizyty, jeśli zespół lub projekt tego wymaga, mimo początkowych deklaracji.
🟡
Mentor developers and support technical delivery
Oprócz zadań technicznych, będziesz odpowiedzialny za wsparcie i rozwój mniej doświadczonych członków zespołu.
