Viktor is an AI coworker service that lives in Slack and connects to workplace tools to perform operational work.
THE SHORT VERSION We’re hiring a Senior Product Designer to shape the core product experience of working with an AI coworker. This is not a role for someone who wants clean briefs, mature playbooks, or perfectly scoped tickets. The category is still being invented. You’ll work from messy problems, ambiguous user behavior, technical constraints, and fast-moving product bets - then turn them into simple, trustworthy, high-craft product experiences. You should be the kind of designer who could thrive in a top product company, but wants more ownership, more speed, and more room to define the thing instead of optimizing a small piece of it. WHAT YOU’LL DO - Design core Viktor product surfaces across Slack, Microsoft Teams, onboarding, integrations, permissions, billing, collaboration, and admin flows - Turn vague, high-stakes product problems into clear interaction models - Work directly with engineers to ship fast, not hand off and disappear - Prototype AI-native UX patterns before the industry has settled on obvious answers - Prototype new AI-native UX patterns before they become obvious to everyone else - Improve clarity, trust, and control in moments where AI behavior can feel confusing - Sweat the details: empty states, loading states, error states, edge cases, copy, spacing, hierarchy - Help raise the product taste bar across everything users touch WHAT WE’RE LOOKING FOR - Strong product taste. You can explain why one flow feels obvious and another feels broken - Very high craft in interface design, typography, layout, and interaction detail - High autonomy. You do not need every problem fully specified before you can move - Speed. You can go from ambiguous problem to prototype to shipped product quickly - Systems thinking. You design reusable patterns, not isolated screens - Comfort with ambiguity. AI products do not have mature playbooks yet - Strong collaboration with engineers. You understand constraints and use them well - A portfolio with real product work, not just beautiful case-study decoration YOU’LL PROBABLY BE A STRONG FIT IF - You’ve worked on products where interaction quality, speed, and trust really matter - You care about reducing hesitation, not just making the UI look premium - You can design both the happy path and the weird edge case - You’re comfortable moving through ambiguity without waiting for perfect requirements - You want to invent interaction patterns for AI coworkers, not copy SaaS dashboards from 2021 EVEN BETTER IF - You've designed for a product-led company with very high UX standards - You use Cursor, Claude Code, Lovable, Replit, v0, or similar tools to turn ideas into working prototypes - You have opinions about AI product UX because you've fought with the tools yourself - You understand the difference between a polished Figma prototype and something people can actually use YOU’RE PROBABLY NOT A FIT IF - You only design what someone else has already fully specified - You see engineering as a handoff partner, not a creative partner - Your product design workflow ends at Figma WHY THIS ROLE MATTERS Most AI products are still designed like chat boxes and dashboards. Viktor needs something better: a product language for delegating work, tracking progress, correcting behavior, understanding cost, trusting outputs, and collaborating with an AI teammate inside the tools people already use every day. You'll help define what good UX for AI coworkers looks like before the category has settled. That's the job. 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.
