About fonio.ai

fonio.ai is an AI voice automation company building AI telephone assistants for small and medium-sized businesses. The product ensures that no business call is ever missed, helping companies stay responsive while focusing on what matters most.

The Role

As a GTM Engineer, you build the systems and processes that power hypergrowth across Europe. You combine modern GTM tools, data, and AI to identify, enrich, and activate scalable outbound and growth engines.

You are not just executing campaigns—you are building the infrastructure behind repeatable revenue generation.

Key Responsibilities

• Build scalable lead generation workflows using tools like Clay, Apollo, HubSpot, Instantly, Smartlead, and similar platforms
• Research, enrich, and qualify leads using multiple data sources and APIs
• Develop and optimize outbound campaigns together with the founding team (targeting, messaging, deliverability)
• Automate sales and marketing processes using AI and modern SaaS tools
• Analyze funnel, conversion, and campaign data to continuously improve performance
• Work closely with Product and Engineering to feed GTM insights back into the product

What You Bring

• Strong growth mindset with a focus on building scalable systems, not one-off campaigns
• Experience with modern GTM and lead generation tools (e.g. Clay, Apollo, HubSpot, Instantly, Smartlead, PhantomBuster)
• Solid understanding of outbound, lead enrichment, ICPs, intent signals, and deliverability
• Technical literacy: comfortable with APIs, automation tools, or light scripting (no need to be a senior engineer, but you should not be intimidated by API documentation)
• Pragmatic execution style: start lean, ship fast, iterate quickly
• Fluent German (mandatory for DACH-focused outbound) and strong English

What You Can Expect

• Build systems that directly impact revenue and company growth
• High autonomy with ownership over GTM infrastructure
• 100% focus time (no regular meetings)
• Extremely fast execution pace with frequent shipping
• Close collaboration with founders, product, and engineering teams
• Direct influence on how fonio scales across Europe

Benefits

• €65,000–€95,000 salary + equity
• 100% remote with optional office in Vienna (7th district, meals included)
• Unlimited budget for tools when ROI is clear
• Access to top-tier GTM, data, and AI tooling
• Fast-moving environment with thousands of customers
