Founding Product Designer / Design Engineer

OverviewWe're looking for a Founding Product Designer / Design Engineer for one of the fastest-growing startups to come out of SSE Business Lab - a Stockholm startup that crossed $3M+ ARR within five months of launching. It's a role for someone who owns the whole loop: understand a painful workflow on Monday, redesign it, build it and have something genuinely better in production by the end of the week. If you want to be early, this is your opportunity. You'd own the product experience end-to-end: the customer product, the creator experience, the internal admin tooling and initially the marketing site and visual identity too. The real job isn't polishing screens and handing them off - it's designing the right thing and shipping the implementation yourself. Who we're looking forYou've shipped core product surfaces from idea to production, not handed off Figma files and waited for engineering to implement themSomeone who lives on the design-engineering boundary: world-class taste plus the technical ability to ship itSomeone with world-class taste in typography, hierarchy, interaction, motion and the details that make software feel premiumSomeone with an extremely high level of agency and autonomyYou've built stuff before (anything around side projects, open source, tools or your own company) and use AI tooling as part of how you buildFluent in English (Swedish not required) ApplicationPlease include a link to your portfolio in the CV that you upload What is offeredA founding-level product role with real ownership and meaningful equityCompetitive compensation: we don't want to filter out rare talent over normal Swedish startup salary bandsWorking directly with the founders on a live product with real traction, based in Stockholm As always at The Qualidex: if you don't tick every box, we still want to hear from you. We care more about trajectory and what you've built than a perfect match. If this role feels like it could be your life's work, take the shot! About usThe Qualidex was founded after feeling how inefficient hiring is. We connect high-potential people with fast-growing startups: You interview with us once, then get access to multiple opportunities without starting from scratch each time. And because a CV doesn't tell the full story, we'd rather see how you think and what you've built.
