Product Engineer (On-site)

The Short Version

You're the person who makes Viktor a product people love, not just a powerful one.

You've shipped real products that real users depend on - end to end, and you have taste: you know what good looks like and you won't ship less.

If you've never shipped a product people love, this isn't the role.

What You'll Actually Do

• Ship user-facing product end to end. Frontend to backend, idea to production, in Slack, Teams, and the web app (incoming!). The bar is something real users touch on day one, not a prototype.

• Own onboarding and time-to-value. From install to first real win in minutes, because the alternative is churn.

• Talk to users and shape the problem. You don't wait for a spec. You find the rough edge, decide what to build, and build it.

• Polish like it matters. The details that separate a tool people tolerate from one they recommend.

• Whatever needs building. Small team, large surface.

The Bar

You ship to production every day, and the changelog has your name on it. You have product taste and you defend it: you know when "it works" isn't done. You work backwards from the user, not forwards from the tech.

This role doesn't work without agentic coding fluency: if agentic engineering isn't already how you work, you'll be behind on day one.

Who You Are

• You've shipped a real product that real people use, and you owned it end to end. A product with real users is the point, not a side project that never left localhost.

• Range. React component to API to deployment script in an afternoon. The frontend/backend divide was never useful to you.

• Product taste. You have opinions about UX, you know what good looks like, and your work shows it without someone handing you a design.

• You talk to users and own outcomes, not tickets. You shape the problem, cut scope when you should, and ship the thing that moves the metric.

• Speed, with the bar up. You ship today, not Thursday, and it's still good.

• Agentic coding is your daily workflow. You build with AI by default and you're faster because of it.

• Genuine drive. You build things because you can't not.

Why This Role Is Different

No layers. You work directly with both founders, and decisions get made in the room, not in a Linear ticket.

You own the surface customers actually see. Every polish win shows up in retention the next week.

We use Viktor to build Viktor. You ship the product using the product, every day.

Real ownership. Not a task. A surface of the company that customers depend on. When it wins, everyone knows whose work it was.

Even Better If

You've founded something or been an early-stage builder.

Design sensibility. You can make it look and feel right, not just function.

You've shipped something with real traction: users, revenue, downloads, a product people know.

You've built with the AI tooling we live in and have opinions about it.

Tech

TypeScript/React on the frontend. Python on the backend and agents. Modal for infrastructure. This role leans frontend and product, but you move across the whole stack. You don't need all of it coming in, but you need to learn fast.

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, and Warsaw. Remote for some roles.
