Bolaget befinner sig i en skalningsfas och satsar hårt på AI för att förändra hur de bygger och driftar mjukvara. Här skriver du produktionskod som faktiskt används, i ett team på ~10+ ingenjörer som tar engineering på allvar: säkerhetstestat, ISO27001-certifierat och med direktkontakt till slutkund. Om rollen Vi söker en fullstack-utvecklare med AI engineering-fokus till deras kontor i Stockholm. Du bygger features tvärs igenom backend och frontend, och använder AI-verktyg för att göra teamet snabbare och bättre på att leverera. Det här är en hands-on roll. Du skriver produktionskod, bygger riktiga features och applicerar AI där det gör faktisk skillnad – inte för att det ser bra ut i en pitch.
