Full Stack House; Poznań; Remote; PLN 120,000 - 180,000; Full time

Job summary

Full Stack House is a senior-led studio delivering premium software experiences. You will own product design end-to-end, shaping visuals, flows, and interfaces in close collaboration with clients and engineers.

This role is fully remote with flexible hours, and we welcome full-time, part-time, or freelance engagements. A strong portfolio demonstrating typography, hierarchy, and UI craft is essential.

Qualifications

• Exceptional visual taste and UI craft—portfolio looks polished and considered with strong typography and hierarchy.
• Strong product/UX fundamentals: user flows, interaction design, end-to-end thinking.
• Proficiency in Figma and design-systems / component-based thinking.
• Comfort with AI-native, rapid prototyping (incl. Claude Code) to validate flows quickly.
• Strong written and spoken English; comfortable talking directly with clients.

Responsibilities

• Own features end-to-end — join client kickoffs, turn loose requirements into user flows and UI, prototype in Figma, iterate on feedback, and hand off to devs.
• Lead rapid prototyping — validate ideas fast using AI tools before committing to full implementation.
• Review dev output — ensure alignment with designs and catch deviations early.
• Build and maintain design systems that our team uses daily.
• Bridge design and code — occasional quick prototyping in code and connect Figma to dev tools via MCP integrations.

Job description

We care most about visual craft. You should sweat typography, spacing, and restraint — your work looks premium and intentional, not template-y. We're a senior-led studio building products that need to feel high-end, closer to a premium coaching service than typical SaaS/ed-tech.

We're Full Stack House, a senior, fast-growing software house building since 2005. We're flat enough that your work will have real impact, but experienced enough to support your growth. You'd own product design end to end: in the room with clients, turning loose requirements into flows and interfaces, prototyping fast with AI tools, and working alongside the engineers who ship it. Fully remote with flexible hours — and full-time, part-time, or freelance is all fine. We care about the work, not the contract type; this is an ongoing collaboration, not one-off project work.

What you'll do

• Own features end-to-end — join client kickoffs, turn loose requirements into user flows and UI, prototype in Figma, iterate on feedback, and hand off to devs.
• Lead rapid prototyping — validate ideas fast using AI tools (Lovable, Claude Code, etc.) before committing to full implementation.
• Review dev output — check that what's being built matches what was designed, catch deviations early.
• Build and maintain design systems that our team actually uses day-to-day.
• Bridge design and code — occasionally hop into codebases for quick prototyping, or connect Figma to dev tools via MCP integrations.

What we're looking for

• Exceptional visual taste and UI craft — a portfolio that looks polished and considered, with strong typography, hierarchy, and attention to detail.
• Strong product/UX fundamentals: user flows, interaction design, end-to-end thinking.
• Proficiency in Figma + design-systems / component-based thinking.
• Comfort with AI-native, rapid prototyping (incl. in-code with tools like Claude Code) to validate flows fast before full build.
• Strong written + spoken English; comfortable talking directly with clients.

Nice to have

• Experience with motion design or micro-interactions.
• Experience in SaaS, e-learning, or media products.
• Based in or near Poznań.
