Your Role

As a Forward Deployment Engineer for our Spanish and Italian markets, 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 both the Spanish and Italian markets. This is a Barcelona-based role, ideally suited to someone who can operate natively in both Spanish and Italian.

What you'll do

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

Who we're looking for

Solid coding skills: you can implement independently, not just configure

Strong understanding of AI systems and LLMs (prompting, tool-use, RAG, failure modes)

Workflow thinking: translate complex processes into robust, testable flows

Experience with APIs, webhooks, auth, and common integration patterns

Cloud fundamentals: deployments, observability, debugging in production

Highly pragmatic working style: ship fast, make it stable, iterate

Bonus: Voice/Telephony, n8n, TypeScript/Python, SQL, monitoring/tracing, GDPR

Spanish and Italian at native or near-native level & English fluent

What we offer

Competitive salary: €65,000–€95,000 per year

Barcelona-based role, with relocation to Vienna for onboarding; we also have one of the coolest offices in Vienna's 7th district (lunch & dinner included)

100% Focus Time (no regular meetings)

Unlimited budget when the ROI is right

Extreme speed (we ship almost daily)

Thousands of enthusiastic customers building the product together with us
