Junior Software Engineer

0to9 AB (publ)

Är du en av de vassaste på KTH som tar examen till sommaren? Ser du Claude, Cursor och V0 som dina närmsta kollegor snarare än bara verktyg? Då vill vi att du bygger framtidens lösningar tillsammans med oss på 0TO9. Om rollen Vi söker en junior stjärna inom Machine Learning och datalogi till vårt Maskin Inlärnings Team. Här handlar det inte om att sitta och harva i gamla legacy-system. Vi bygger nytt, snabbt och smart. Vi letar efter dig som anammat "vibe coding"-filosofin: du fokuserar på arkitektur, logik och kreativitet, medan du låter de absolut senaste AI-verktygen sköta grovjobbet med koden. Vem är du? Du läser sista terminen på en relevant civilingenjörs- eller masterutbildning med planerad examen till sommaren. Du har förmodligen byggt egna projekt där du använt LLM:er för att accelerera din utveckling. Du är "power user" av verktyg som Cursor, Replit eller liknande. Du har en stabil grund i datalogi och förstår mekanismerna bakom ML, men du föredrar att applicera dem praktiskt snarare än att bara teoretisera. Att förstå och utmana kod/arkitektur är dock ett måste. Du fattar att den bästa koden är den som löser problemet snabbast och säkrast. Verktyg Objektorienterad Python, Numpy/Pandas, Pytorch , Sklearn Teoretiskt passion & förståelse för klassiska som nyare ML algoritmer Vad vi erbjuder Jobba från "Sveriges snyggaste kontor 2025" mitt i hjärtat av Stockholm.
