Senior Product Designer

About the role

As a Senior Product Designer at Fluxon, you'll lead design end-to-end on ambitious projects, often working directly with founders and product leads to shape what gets built. We are looking for design generalists — someone who owns the design surface, thrives in ambiguity, and cares as much about why something gets built as how it ships. This position is fully remote and open to candidates based anywhere in Poland.

What you'll do

• Partner with founders, product leads, and other stakeholders to turn business goals into experiences customers love
• Lead design end-to-end, from discovery and research through interaction design and production-ready execution, calling the right level of depth for each project
• Make the right call when user needs, technical constraints, and business goals pull in different directions
• Collaborate closely with clients, PMs, and engineers to set the direction and ship high quality work
• Bring a point of view on craft, process, and where the field is going, while staying current with new technologies and design trends

Qualifications

• Experience leading product design end-to-end, from strategy through to production-ready execution, delivering work that customers love and drives business results
• Strong judgment on process: knowing when to go deep on research and when to move fast
• Strong UX foundations across the full discovery and design process, from research through interaction design, user testing and accessibility
• Strong visual craft across layout, typography, iconography, color, and motion, with the ability to take work to a polished, production-ready bar
• Excellent communication and presentation skills across written, visual, and spoken formats, with experience presenting directly to clients
• Comfortable collaborating closely with clients, PMs, and engineers, including managing expectations and navigating disagreement
• Experience shipping with startups or founding teams, comfortable building from zero without established design foundations or process
• Experience working with US clients (European clients a plus)

A note on applications: a portfolio is a required part of your application — it is treated as a critical element of the review process and must be included in your submission.

What Fluxon offers

• Remote-first, flexible work with a budget to set up a workspace that works for you
• Localized healthcare coverage, flexible paid time off (minimum 3 weeks plus holidays), and "no internal meetings" Fridays
• A professional growth budget, a monthly wellness allowance, and annual company offsites
• A competitive salary, profit-sharing, and a paid sabbatical program
