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.
Requirements
Experience:
Any relevant experience in web or mobile development is welcome; we are open to junior, mid-level and senior candidates who demonstrate strong practical skills and a willingness to learn.
Technical Skills:
Required:
* Proficiency with _Next.js_, _React_ and _TypeScript_.

Nice to have:
* _Tailwind CSS_, _Prisma_, PostgreSQL or _Supabase_.
* _Python_ and _FastAPI_ for backend services.
* _Docker_ and _Kubernetes_ basics; experience with real-time features, audio or AI products.
Communication:
* _English proficiency is essential, both written and spoken, as it is the working language for all positions._
* German is a plus.
Soft Skills:
* Ability to work independently and as part of a distributed team.
* Product sense: you ask why before you build.
* Willingness to take ownership of features and contribute to team discussions.
Benefits
* Flexible Work Setup: Work fully remotely or from a co-working space — whichever suits you best.
* Equipment Provided: Company laptop and phone provided for all employees.
* Collaborative Environment: Join a small, agile team where your contributions have a direct impact.
