Job Description

W Code & Pepper tworzymy produkty z obszaru FinTech, HealthTech i AI. Pracujemy głównie dla klientów zagranicznych, budując systemy, które realnie działają, skalują się i przechodzą audyty.

Nie sprzedajemy historii o „innowacjach” i „dynamicznym środowisku”. Interesuje nas konkret: architektura, decyzje technologiczne i kod, który dowozi. Budujemy systemy, które przechodzą audyty, skalują się i realnie wspierają biznes - bez sztucznego nadęcia.

Obecnie szukamy osób, które interesuje budowa middleware hubu dla platformy Direct Market Access (DMA) - systemu, który:

• monitoruje wyniki traderów,

• wylicza metryki ryzyka,

• integruje się z zewnętrznymi platformami tradingowymi,

• obsługuje real-time data streaming.

To rola dla kogoś kto lubi odpowiedzialność za architekturę backendu oraz kluczowe decyzje technologiczne.
