Your Role
As our GTM Engineer, you own our outbound engine end-to-end. You build and run the email marketing outreach machine that puts fonio in front of thousands of the right prospects every month – at high volume, high deliverability, and with copy that actually converts

Who We're Looking For

Someone who already:

• Knows cold email deliverability inside out – you understand domains, inbox setup, warmup, SPF/DKIM/DMARC, bounce hygiene and how to consistently land in the primary inbox instead of spam.

• Has built high-volume sending infrastructure – you've operated dozens or hundreds of mailboxes and domains across tools like Smartlead or Instantly, and you know how to scale sending safely to 6–7 figures per month.

• Writes copy that sounds human, not templated

• Owns data and list building

• Thinks in experiments – A/B testing, conversion rate optimization, and decisions driven by numbers.

• Knows modern MarTech and CRM stacks.

• Speaks German at native level and is fluent in English.

What You'll Do

• Own the Outbound Engine

• Build & Scale the Infra

• Write & Test Copy

• Own the Growth Stack

• Turn Data into Pipeline

What We Offer

• Competitive salary: €80,000–100,000 per year

• 100% Remote: But if you're into office life, we have one of the coolest offices in Vienna's 7th district (lunch & dinner included).

• a lot of focus time (no regular meetings)

• Unlimited budget when the ROI is there

• Extreme speed (we ship almost daily)

• Thousands of enthusiastic customers building the product together with us.
