Job Description This is a remote position. APPLICATION DEADLINE: JUNE 30, 2026 This position may close earlier than the advertised deadline if we receive a sufficient number of applications. We therefore recommend that you apply as soon as possible. We are looking for a Senior Product Designer with excellent knowledge of B2B SaaS UI, with enough experience to immediately recognize how good enterprise software should look and work - and how it shouldn't. You can be a designer who learned to code, or a UI developer with excellent taste and judgment. In the AI-first era, the line between the two professions matters much less than your instinct for what's good. The main focus of this role is the Nimbus Data Systems Events platform: our core commercial product built on ASP.NET that handles complex workflows in event management, ticketing, hospitality and guest management. It has a solid foundation and a loyal customer base. It also has real UX and UI debt that has accumulated over years of continuous development. You are here to transform it, not maintain it. What makes this role interesting is how you will implement your work. Instead of handing off designs to the development team, you will use AI-powered coding tools (primarily Cursor) to make changes directly to the codebase. You don’t need a formal engineering background. But you do need real fluency with these tools and the ability to quickly learn. The selection process includes a real-time practical test. You will report to the Principal Product Architect – an experienced product design manager who is highly collaborative and actively involved.
