Senior Product Designer

Why Polar?

It's never been easier to build, ship and scale software.

But it's never been harder to monetize it.

We're obsessed over solving this to empower the future one-developer unicorns.

These unicorns will be rare but inevitable. Whether in 3, 5, or 10+ years, they also symbolize a broader shift already in motion and accelerating:

• Smaller & smaller teams with...

• Exponential revenue/employee growth

• Focusing fully on their core product and marketing. Delegating & automating everything else that's boilerplate – be it in their codebase or business operations.

Exceptional billing primitives, APIs, SDKs and abstractions are a crucial foundation, but not enough. They will need a full-fledged platform to oversee, manage and scale their business.

Turning their software into an international business in 6 lines of code.

Join our small, talented and engineering-led team across Europe to shape how future software businesses are built. We focus on shipping at high velocity to serve developers in unlocking their next stage with their business. Everything else is secondary.

Role & responsibilities

We're hiring a Senior Product Designer to craft the experience of Polar across our dashboard, SDKs, and developer-facing surfaces. You'll design end-to-end product flows — from onboarding, checkout, dashboard to customer portals and emails — always with the goal of making complex billing feel effortless and magical for developers and their customers.

You'll own our design system, collaborate closely with engineers, and bring clarity and polish to every part of the product. You'll also help shape product direction directly, working hand-in-hand with Birk (Founder), design- and product engineers, and our community.

• Design end-to-end product experiences: flows, interfaces, prototypes, and interactions

• Create and maintain a design system that balances speed, consistency, and craft

• Collaborate with team to scope, refine, and iterate to ship world-class features and user experiences

• Work directly with developers (customers + open source community) to understand needs and turn feedback into elegant solutions

• Prototype and test concepts quickly — from Figma mocks to prototypes made in Cursor / Claude Code.

• Champion craft: typography, animations, micro-interactions, and developer ergonomics

• Contribute to our open source repos where design and developer experience overlap

What we're looking for

• 7+ years of experience designing digital products end-to-end

• Strong portfolio showcasing thoughtful UX, clean UI, and polished interactions

• Comfortable designing complex, data-rich, or developer-facing products

• Proficient with modern design and AI tools (Figma, Cursor/Claude Code, prototyping tools, etc.)

• Excellent communicator who thrives in close collaboration with engineers and product managers

• Someone experienced setting direction and designing for the future of the product while still executing and polishing current efforts and features

• You're comfortable building the first prototype (React, , Tailwind + using AI) when needed vs. delivering a static design alone

• (Bonus) Experience designing for developer tools, SDKs, or APIs

• (Bonus) Contributions to open source design systems or component libraries
