Job description

Intro

For this position we are only looking for candidates located in Greece, Germany or Austria.

Nairon GmbH is a Swiss startup building AI voice agents that answer and make phone calls for businesses. Our platform runs real-time conversations over the phone and on the web, connected to our customers' telephony and business tools.

• Building our native companion app with Expo / React Native or Swift.
• Building features across the stack, from the user interface to the database with Prisma and PostgreSQL, and the Python services behind them.
• Owning features end to end: turning customer needs into requirements, shipping them and checking that they help.
• Applying DevOps practices to support development and deployment, including Docker and, when appropriate, Kubernetes.
• Participating in technical discussions, code reviews and architectural planning.
