Your Role

As a Forward Deployed Engineer for our Spanish 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 Spanish 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 we are 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 at native or near-native level & English fluent

What you get

• Competitive salary: €65,000-€95,000 per year

• Equity

• Relocation support

• Daily lunch and dinner

• Equipment of your choice

• Regular team off-sites
