Principal Product Designer

An agile UK-based SaaS is disrupting the digital research space with a high-growth platform used by over half a million users. Operating as a remote-first team that champions autonomy and high-impact innovation, they have built a sophisticated, security-first ecosystem powered by C#, .NET, and React. My client seeks a high-impact Principal Product Designer to be the design anchor for this AI-powered platform. In this pivotal role, you will bridge the gap between high-level product strategy and hands-on execution, owning the end-to-end user experience from the moment a user lands on the website to the point they derive deep value from the software.

You will not just design features. You will lead the evolution of a unified design language that spans marketing, brand storytelling, and complex product workflows. You will turn technical complexity into elegant clarity, using AI as a design partner to create user journeys that feel simple, fast, and empowering. If you are ready to play a defining role in scaling a platform built for the modern web, this is your chance to leave a lasting mark on a global product.

The Role

• Product Design Leadership: Lead end-to-end design across user research, prototyping, and delivery, focusing on onboarding and AI-first workflows.
• Web and Marketing Ownership: Own the UX and design for the public website and conversion-critical landing pages, ensuring brand consistency across all channels.
• Player Coach Mentality: Act as a hands-on designer producing beautiful work while simultaneously setting standards, defining ways of working, and guiding a value-aligned design culture.
• Data-Driven Design: Use qualitative and quantitative data from tools such as Mixpanel or Power BI to validate design decisions and measure what matters most to users.
• Technical Innovation: Rapidly prototype using modern tools and translate complex AI outputs into elegant, accessible interfaces.
• Cross-Functional Collaboration: Partner closely with Engineering, Marketing, and Customer Success to ensure design excellence is embedded in every touchpoint.

About You

My client is seeking a thoughtful and experienced designer who is excited by complexity and motivated by impact. You are a proactive collaborator and a craft-led thinker who puts inclusive design at the heart of everything you create.
