The market right now

Alion currently lists 841 open Backend Developer jobs in Warsaw from 326 companies. 171 of them were posted or refreshed in the last seven days. 287 of the employers have posted something in the last three months, which is the pool worth watching if you are starting a search now. 15 of the 841 carry the marks of a stale or abandoned posting - open far beyond the usual time to fill, reposted, or on a board that mostly never closes a role - and are marked as likely inactive; the list can hide them. Every listing links straight to the employer, so you apply on their own board rather than through an intermediary.

What these roles pay

277 of these Backend Developer jobs in Warsaw state pay directly. Across them the middle half of the market sits between $66K and $92K a year, with a median of $78K. By level, the median runs junior at $57K, middle at $66K, senior at $80K, staff at $91K, and lead at $98K. The step from junior to lead is worth about 1.7x on median pay. Figures are gross annual amounts converted to US dollars, so roles in different currencies stay comparable.

The largest concentrations of these roles are Poland (841), Spain (16), Germany (15), Netherlands (13), and Czech Republic (10). 25% of the listings are fully remote and a further 45% are hybrid, so a large part of this market is open to you regardless of where you live.
