Intro
_For this position we are only looking for candidates located in Germany, Austria or Switzerland._
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 Forward Deployed Engineer at NAIRON, you will work directly with our customers and make the platform do what they need. Your responsibilities will include:
* Building voice agents and conversation flows for customers, from the first workshop to go-live.
* Connecting the platform to customers' systems: CRMs, ticketing, calendars, internal APIs and their phone setup.
* Writing integration code and small services in _Python_ or _TypeScript_.
* Debugging live calls with customers: reading logs and traces, finding the cause, fixing it or handing it to the core team with a clear report.
* Turning what you learn on site into product improvements, together with engineering.
* Supporting pre-sales with technical answers when a deal needs an engineer.
Requirements
Experience:
A mid-level engineer, or a developer with several years in solution engineering, integration or technical customer work.
Technical Skills:
Required:
* Solid _Python_ or _TypeScript_; REST APIs, webhooks and authentication.
* Comfort reading logs and traces and debugging systems you did not write.
* Basic understanding of how telephony or real-time media works, or the will to learn it fast.
Nice to have:
* Experience with LLMs, prompt design or conversational AI.
* SIP, PBX or contact-centre systems.
* _Docker_, cloud platforms, CRM platforms such as _HubSpot_ or _Salesforce_.
Communication:
* _German at business-fluent level (C1) is essential, as you work with our customers in German._
* _Good English, as it is our internal working language._
Soft Skills:
* You enjoy being in front of customers and stay calm when something breaks in a live call.
* Ownership: you follow a customer problem until it is solved.
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: Work across product, engineering and customers, and grow into solution architecture or product roles.
Closing
If you like building with customers rather than for them, we'd love to hear from you.
