Forward Deployed Engineer

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.

If you like building with customers rather than for them, we'd love to hear from you.
