The Role

As a Forward Deployed Engineer for our DACH market, you work directly at the intersection of product and customer setups. You capture requirements, translate them into robust implementations, and take fonio live at customers – including integrations, automations, and ongoing optimization.

You work closely with Product/Engineering and Go-to-Market, making sure deployments are fast, stable, and repeatable across the DACH market.

What to Expect

Capture customer requirements and translate them into concrete implementation plans

Build and roll out fonio setups in production: workflows, logic, prompts, guardrails

Implement integrations with third-party systems (APIs, webhooks, CRM, calendar, ticketing, etc.)

Develop smaller features and glue code to cleanly map customer cases

Debug under production conditions: calls, flows, edge cases, fast fixes

Build reusable templates and deployment playbooks to make setups scalable

Deliver product feedback: bring pain points and feature gaps to the team, prioritized and concrete

What You Bring
