Job description

Marketing · Warsaw or Munich onsite · FullTime · Mid level

This role is for an engineer who treats growth as a product problem. The work is finding where new users stall on the way to a first good result, then building and shipping the fix, with each change measured. A strong candidate has moved activation, retention or conversion before, can show the numbers, and writes their own code all the way through the stack, including the database.

How it fits the AI era

Viktor is an AI employee people talk to, so growth here means making a first task go well, not polishing screens. Onboarding conversations, defaults and nudges matter as much as buttons. AI coding tools speed up the building, while judgment about what builds trust, what to test and how to read results stays with the person.

How it builds AI experience

The product is itself an AI agent that writes and runs code inside Slack and Teams, so the work offers close contact with how people really hand tasks to an AI and where trust breaks down. The team also builds Viktor with Viktor, which gives daily practice with agentic coding. Someone preparing for this could use AI coding tools on a small product with real users and track what changes behavior.

Worth showing

• Activation or retention gains with numbers
• A/B tests that changed decisions
• Shipped product with real users
• Funnel and metric analysis
• Agentic coding in daily work
