Senior Product Designer

About Katana

Katana builds powerful inventory and manufacturing software for 1,500+ businesses that make and sell physical products around the world. We're an AI-first SaaS company, and that shows up in how we build as much as in what we build.

We've just stepped into an exciting new phase of expansion - moving beyond small merchants into a larger market of modern, multi-channel, multi-location businesses. With that growth comes bigger opportunities, more complex problems, and the chance to shape how we scale. Our 100+ person team across 10+ countries is building what's next - together. And that's where you come in.

Three things about this seat worth knowing before anything else.

Real ownership. You own a product domain end to end - the customer interviews, the problem framing, the design, the thing that ships, and the number that moves afterwards. Roadmap items at Katana aren't a product manager's by default. Designers and engineers lead them too, and we'll expect you to want one.

Speed. Sketch an idea Monday, put a working prototype in front of a real customer by Friday - built with AI on our design system, running on their own data. We work in cycles of two weeks or less, in vertical slices. Designers here have already taken roadmap work from prototype straight to a production pull request, and making that the default is part of this job.

Visibility. You report to the CPO. You present your own work, your own experiments, and your own misses - directly, to the person making the calls. Nothing gets absorbed into team output on its way up.

This isn't a role for someone who wants a bigger version of the job they already have. It's for someone ready to own something that matters, at a company moving fast enough that your work shows up in the product within weeks, not years. If you want to shape how a product gets designed while that is still being worked out, this is a seat where you actually can.

Where you'll work

This role is hybrid from our Tallinn office. Tuesday to Thursday are office days; Monday and Friday are up to you. It's the way our product team works - that's when the whole team is in the room, and the face-to-face time makes the work move faster and the collaboration sharper. If you're not already in Estonia, we're happy to support relocation from within Europe for the right person.

About the role

You'll join the Platform & Intelligence team - the team that pushes forward every AI initiative at Katana - and you'll report directly to our CPO. You'll work in a pair with another senior product designer, splitting the ground between you and debating the hard parts together.

It's a senior seat with real scope, and it sits in the most interesting place in the company right now.

This is frontier work in the most literal sense. We're building towards a Katana that a customer can simply talk to: ask "did I actually make money on this product?" in plain English and get a trustworthy, sourced answer out of their own operational data, then act on it - creating real purchase orders and manufacturing orders in a live system of record. We're also putting Katana inside the AI tools customers already use, through connectors for Claude, ChatGPT and Gemini, so we own the experience without owning the screen it renders on.

Nobody has a finished design language for any of this. How you show a customer where an answer came from so they trust it. How you ask for confirmation before writing to live inventory, and how you let someone undo it. How you make an assistant saying "I can't answer that one yet" read as confidence rather than failure. What a design system even needs to become when a growing part of the product is conversational rather than composed of screens. These are open design problems, and they'd be yours.

To be clear about scope: this isn't a design-ops or pixel-execution seat. We want the designer who framed the problem, not the one who styled the answer. You'll do your own research, argue for the user in roadmap decisions, and be accountable for whether the design moved a number. The learning curve is real - Katana is a deep operational product and our customers' businesses are genuinely complicated. So is the opportunity.

Katana AI - the job

This is the main focus of the role, the team's core bet, and the reason the seat exists.

Own the design of the in-product Katana AI experience end to end , from the first prototype through beta to something customers rely on daily.

Design the trust layer , which is the hard part: sourced answers, confirm-before-write safeguards, permissions, audit trails, and undo for anything the AI changed.

Design for the moment the assistant doesn't just report a number but explains why it's wrong and offers to fix it. Our strongest customer signal is that people don't trust the figures they see. Solving that is the differentiator.

Shape how proactive insight reaches customers , so they hear about a stockout, a late supplier, or a margin slip before it hurts them, without the product turning into noise.

Work on how Katana shows up inside other AI tools through our MCP connectors, where we shape the experience without controlling the interface.

Run the research that tells us which of this is real , and set the KPIs that tell us whether it worked.
