Founding Product Manager

Viktor; Warszawa; On-site; PLN 260,000 - 360,000; Full time

Job summary

Viktor is seeking a founding Product Manager in Warsaw to own activation, retention, and monetization across the user journey. You will run the experiment loop, form hypotheses, instrument results with SQL and HogQL, and ship A/B tests end-to-end. You’ll write PRDs and microcopy, live in Linear, and partner with co-founders and engineering to move fast.

The role offers ownership, a fast-moving environment, and the freedom to shape product-led growth with real impact on metrics and customers.

Qualifications

• 4 to 8 years as a PM at a PLG SaaS company or mobile gaming, with ARR growth you can attribute to your work.
• SQL and PostHog/HogQL fluent. You write your own queries and don't outsource the truth.
• You've shipped in-product growth surfaces with engineering and have the before/after numbers.
• You write your own PRDs, live in Linear, and are copy-capable on in-product microcopy.
• Opinionated on integration, OAuth, auth-funnel drop, and retention cohort work. You've done both.

Responsibilities

• Own activation, retention, and monetization across the user journey.
• Run the experiment loop: onboarding, integration activation, pricing, churn-recovery, in-product surfaces.
• Inherit a pipeline already in flight: onboarding reorder, auto-connect, installer drip, pricing tests, dashboard v1.
• Write your own queries and bring data-driven answers to the team.
• Write PRDs and microcopy; manage nudge copy and pricing card math.
• Work shoulder-to-shoulder with the co-founders and engineering.

Job description

The Short Version

You look at a funnel and see money on the floor. You write your own SQL, write your own PRDs, and have shipped enough in-product growth surfaces to know which ones move numbers and which look good in a deck. Equal parts product manager, analyst, and editor. You ship every week.

What's Actually Going On Here

The product works. Users who stick, love it. The question is whether we can turn more of them into long-term customers. Activation, retention, and monetization are where the next chapter of growth comes from, and right now nobody owns them end-to-end.

You'll be our founding PM. No PM above you, no playbook to inherit. You build the engine: how we form hypotheses, instrument them, ship A/Bs, and decide what scales and what dies. You have the budget and the freedom to move fast.

What You'll Actually Do

• Own activation, retention, and monetization across the user journey. Not paid acquisition, not brand: that frees you to go deep on the product-led growth engine.

• Run the experiment loop. Onboarding, integration activation, pricing, churn-recovery, in-product surfaces. Hypothesis, instrument, ship with engineering, read the data, decide. Three experiments live at any time.

• Inherit a pipeline already in flight: onboarding reorder, auto-connect, installer drip, credit top-up pricing tests, dashboard v1. Day one, you have momentum.

• Write your own queries. PostHog and HogQL fluent. You go find out, then bring the answer to the team.

• Write your own PRDs and microcopy. You live in Linear. The copy on the nudge, the order of the steps, the math on the pricing card: that's all you.

• Work shoulder-to-shoulder with the co-founders and engineering. They'll have opinions, you'll have data, and the good ones win.

Personally Execute

Activation funnel instrumentation and cohort analysis. Integration-drop recovery. In-product activation surfaces. Retention cohort work, first priority. Charge-failure recovery. Expansion triggers. Three live experiments at all times.

How You'll Know It's Working

• 30 days. Activation and retention funnel instrumented. Three experiment specs ready. Retention baseline locked.

• 60 days. Integration-drop recovery v2 shipped. First charge-failure recovery flow live. One expansion trigger live.

• 90 days. Integration drop and charge failure both moved. Four-week retention trending up, target 22%+. Two expansion triggers live.

Beyond that: the founders stop running growth experiments themselves, because you're better at it. The P&L moves and you can point to the experiments that did it.

Who You Are

• 4 to 8 years as a PM at a PLG SaaS company or mobile gaming, with ARR growth you can attribute to your work.

• SQL and PostHog/HogQL fluent. You write your own queries and don't outsource the truth.

• You've shipped in-product growth surfaces with engineering and have the before/after numbers.

• You write your own PRDs, live in Linear, and are copy-capable on in-product microcopy.

• Opinionated on integration, OAuth, auth-funnel drop, and retention cohort work. You've done both.

• Founder mentality. You're building a function, not inheriting one.

• Warsaw-based, on-site.

Why This Role Is Different

• No layers. No PM above you, no growth director between you and the work. You set the playbook.

• The experiments you ship define the company's economics. At this stage, retention and monetization curves bend the trajectory permanently.

• The product makes the work easier. People who try it, love it. You're compounding a good product, not papering over a leaky one.

• The co-founders already believe growth is strategic. No convincing anyone it matters.

Even Better If

• You've worked on AI products and understand trial-to-paid when usage is metered and value is non-obvious early.

• You've owned pricing and packaging end-to-end and have scars from one that didn't go to plan.

• You've worked where founders were deep in the metrics and you loved partnering on it.

How we work

Small team, high trust, low process. Decisions are made by owners, not committees. You will ship your first week. You will talk to users your first day.

We don't do alignment meetings or stakeholder syncs. We build things, see if they work, and iterate.

Why Viktor

We're one of the fastest-growing companies in the world. The product works. The market is pulling.

This is a rare window: everyone here owns something real. Not a task. A surface of the company that customers depend on.

That doesn't last forever. Right now, it's still true.

Compensation

Top-of-the-market salary and the kind of ownership that only exists at this stage.

The best work happens when you're in the room. Munich, New York, Dublin, and Warsaw. Remote for some roles.
