Senior Product Designer

About Bitstack

It all started with an idea in 2021. Initially built to democratize Bitcoin in France, Bitstack has gone from a simple product that invests spare change in bitcoin, to a crypto-native bank bringing a better way to save, spend, and grow money to our 300K+ users. We want to rebuild finance from the ground up to empower people to achieve financial freedom by participating in a more open and inclusive financial system. We’re a small, ambitious team of operators. We believe in moving fast, sweating the details, and creating products people truly love. At Bitstack, you’ll have the opportunity to shape not just our products, but the culture and practices of our entire organization. Bitstack is backed by YC, leading VCs like 13books Capital, Stillmark, Serena, and many more. We are building a product our users love and we are just getting started!

The role

At Bitstack, we believe that great product & design are key to win in a competitive market.

Since we operate without product managers, you’ll have the opportunity to lead projects end-to-end, from discovery to delivery, working side by side with engineers. You’ll own the vision, the craft, and the impact.

For this role, we expect robust design skills, sharp product thinking, and the ability to engage in technical discussions. We work in small, autonomous project teams, where engineers are paired tightly with designers to explore ideas, build prototypes, deploy internal builds, and ultimately ship to customers. You will be a key element of projects from beginning to end.

We value extreme ownership, high velocity, and low-ego collaboration. If you’re a designer who obsesses over details, loves solving complex problems, and care about craft over process, you’ll thrive here.

What You'll Do

• Collaborate closely with engineering, care, and compliance to deliver impactful projects
• Lead end-to-end design initiatives, from idea to polished delivery, and taking ownership for achieving their success
• Create mockups, prototypes, and high-quality visuals with exceptional attention to detail
• Use and improve our lightweight design system components
• Communicate design decisions with clarity, inviting feedback while holding a strong vision
• Contribute to set the bar for design quality and the culture for how design works at Bitstack

What We’re Looking For

• Proven track record of designing high-quality products in fast-paced start-up environment
• A portfolio featuring exceptional craft, taste, and problem solving
• Strong command of visual design, UI patterns, and interaction principles
• Experience with prototyping in Figma (and beyond with tools like AI)
• Ability to lead projects independently — from discovery to shipping
• Pragmatic mindset: you balance design quality with speed, business goals, and technical constraints
• Clear communicator who can distill feedback and articulate design decisions
• Bonus: You ship to production, perhaps with a little help from AI

We hire talented and passionate people from all kinds of backgrounds, we don’t care about your age or where you studied. If you’re excited about the role but your past experience doesn’t match every bullet point in the job description, we still encourage you to apply. What matters most is that you’re a builder at heart, you share our values, and you’re enthusiastic about our mission.
