About the role
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. We value clear communication, thoughtful engineering, and a collaborative approach to problem-solving. Join us as we continue to develop tools that make a difference.
Tasks
As a Full-Stack & Mobile Engineer at Nairon GmbH, you will build our product on the web and on the phone in the customer's hand. Your responsibilities will include:
* Designing, developing and maintaining our web application with Next.js, React, Tailwind CSS and TypeScript: the flow editor, call analytics, billing and partner 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. * Experience building mobile apps with Expo / React Native, Swift or a comparable stack.
Nice to have:

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. * Growth Opportunities: Web, backend and mobile in one role, with the chance to expand into AI-related work over time.
