About the Role

Bei Arvana bauen wir die erste AI-native Go-To-Market Firma in DACH. Seit 2024 sind wir auf über €5M ARR und 30+ Leute im Team gewachsen mit über 200 B2B-Tech-Unternehmen als Kunden. Unser Team arbeitet täglich mit eigener Software (Arvana OS) und lokalen KI-Agenten, die wir auf eigener Hardware betreiben. Als Software Engineer bei Arvana entwickelst du beides weiter.

Responsibilities

  • Develop Arvana OS further: Next.js in the frontend, Python in the backend, Postgres underneath.
  • Build features end-to-end, not just one layer of it.
  • Model our data model in Supabase and Snowflake.
  • Integrate external tools like Smartlead, HeyReach, or Pipedrive into our system.
  • Build local AI agents and operate them on our own infrastructure.
  • Work daily with Claude Code.
  • Write tests and ensure clear error messages.

Requirements

  • Have 2 to 5 years of experience as a software developer.
  • Have built products that real users use daily.
  • Have initial experience with TypeScript, Python, and React/Next.js.
  • Understand databases deeply; SQL is a tool, not a crutch.
  • Productively use AI tools and know when to verify.
  • Work independently and make decisions.
  • Master German and English fluently in speaking and writing.
  • Familiarity with Data Warehouses, n8n, or self-hosting LLMs is a plus.
