Job description

About Whale

Whale is the #1 AI-powered SOP platform. We help growing companies onboard faster and stop losing knowledge when people leave. We’re past 1,000 customers and heading for €10M ARR. Plenty of people sign up. Turning more of them into paying customers, and building the system that does it on repeat, is where you come in. That’s the job.

What You’ll Own

• Activation and lifecycle. Own the email and in-app flows that take a signup from first login to active to paying. Hunt down the drop-offs and fix them.
• Conversion experiments. Own the signup flow and run tests that move free to paid. Keep what works, cut what doesn’t.
• The growth engine. Wire up automations and AI agents (HubSpot, n8n) so the repetitive work runs itself.
• Be AI-native for real. Use AI to produce and ship at a volume that normally takes a whole team.
• Own your numbers. Report what moved every week. No vanity metrics.

You’re a fit if you

• Have run growth or lifecycle marketing in B2B SaaS and can show what you moved.
• Are genuinely AI-native. You reach for AI before doing things by hand, and can show what you’ve built with it.
• Are technical enough to wire your own stack (HubSpot, automations, analytics) without waiting on engineering.
• Ship tests and read the results without hand-wringing.
• Move fast and finish. You’d rather ship and iterate than polish forever.
• Write clear, human copy that converts.
• Stay organized with a lot in flight.

Our Core Values

At Whale, we don’t believe you just stick the values on a wall somewhere. We live and breathe them in everything we do, from product to meetings to team feedback and more.

Agility is in our DNA: we move fast, iterate quickly, and stay focused on creating value.

We believe in simplicity with depth: every interaction should be easy without sacrificing quality.

We own the ship: we take initiative, act with autonomy, and lead even through ambiguity.

We challenge, then unite: diverse perspectives make us stronger, and once aligned, we move as one.

Above all, we are humble and honest: we respect each other, give feedback with care, and keep it real.
