Senior UX/UI Designer - Remote Freelance (m/f/d)

About the role

We are looking for an experienced and autonomous Senior UI/UX Designer (Freelance) to audit and elevate the user experience of our data-heavy B2B web application. In this role, you will not be driving an abstract greenfield rebrand or creating an entirely new design system from scratch; rather, you will be delivering focused, highly pragmatic design specifications and UX improvements that our engineering team can build directly.

Reporting directly to our Head of Product and collaborating closely with our frontend engineers (Angular / Angular Material), you will translate complex domain workflows into intuitive, high-utility interaction designs. The engagement is planned for a total of 120 hours across 2027 (~30 h/month in the initial audit and specification phase, tapering to a light monthly retainer of ~5 h/month for design QA and ongoing advisory).

Your mission

• Conduct a comprehensive UX heuristic audit of core product areas and prioritize usability issues based on business and user impact.

• Specify clear, end-to-end user flows through wireframes, diagrams, and low- to high-fidelity mockups.

• Design visual specifications for complex UI components, including interactive widgets, preview curve creation tools, and mini diagrams.

• Establish consistency guidelines for recurring elements (e.g., chips, dropdowns, form controls, tables, and filters) built on top of Angular Material.

• Lead design handover sessions with frontend engineers and maintain open, constructive communication to address technical feasibility questions.

• Conduct design QA on implemented screens and support the product team on a flexible monthly retainer basis.

Your profile

• 5+ years of UI/UX design experience, operating at a proven senior level.

• Demonstrated track record with enterprise SaaS or data-heavy B2B software showcasing strong interaction design for dense data tables, multi-level filters, analytical charts, and complex setup flows.

• Hands-on proficiency with Figma (or equivalent industry-standard tooling) and creating developer-ready design specs.

• Experience designing within established component systems, particularly Material Design / Angular Material or similar component libraries.

• Strong technical communication and handover skills, with a track record of partnering smoothly with frontend engineering teams.

• Fluent English (written and verbal).

• Location & Availability: Based remotely in the EU, Ukraine, or Turkey (Berlin-adjacent is a plus for occasional on-site sessions); available starting January 2027 with capacity for ~30 h/month initially and a ~5 h/month retainer through December 2027.

• Nice to have: Prior experience in pricing software, retail analytics, or mathematical optimization platforms.

What we offer?

• Competitive hourly rate of €90–€110 net (excl. VAT), capped at 120 hours (€10,800–€13,200 total net budget).

• 100% remote setup with flexible hours aligned with European working time zones.

• Culture of autonomy and direct impact, working on critical product workflows with high visibility and minimal bureaucracy.
