About the Company

An AI-native SaaS startup building the AI teammate that lives inside Slack and Microsoft Teams - connecting to thousands of tools and doing real work for real companies across finance, marketing, ops, and engineering. The product replaces half the SaaS stack with a single teammate. The team is small. The scope is not.

The Short Version

A Senior Product Designer is needed 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 optimising a small piece of it.

What You'll Do

Design core 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
Improve clarity, trust, and control in moments where AI behaviour 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. This company needs something better: a product language for delegating work, tracking progress, correcting behaviour, 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. No alignment meetings or stakeholder syncs. Build things, see if they work, iterate.

Everyone here owns something real. Not a task. A surface of the company that customers depend on. When it breaks, you fix it. When it wins, everyone knows whose work it was.

Compensation

Competitive salary and the kind of ownership that only exists at this stage.

Based in Munich, New York, and Warsaw. Onsite preferred. The best work happens when you're in the room.
