About the Role
We're hiring a Lead Product UX/UI Designer on a six month fixed term contract to own the end-to-end design of Say So's product experience, from research through to shipped, polished UI.
This is a senior individual contributor role with real ownership: you'll shape how the product looks, feels, and works, and you'll be the person closest to our users' behaviour and feedback.
You'll be based in our London office, reporting directly to the Creative Director who is based in New York and will work closely with Product, Engineering, and the broader Caliber design team to ensure Say So's experience is best-in-class while staying consistent with Caliber's cross-brand design system.
About Caliber
Caliber is a media company built to define a new era for journalism.
All brands in the Caliber family reimagine how stories are created, shared, and valued.
SAy So is one of these brands - an app that gathers and curates the stories that matter to you by individual creators and journalists in the way you want to receive them.
At Caliber we meet modern audiences on their terms, in their tone, and on their time, supporting storytellers with the tools, training, and rigour to shape the world with integrity.
With newsrooms in New York and London, and a global network of trained creators, we deliver stories that matter—shaped by robust measurement and a deep understanding of digital platforms.
At the heart of our business is The Caliber Collective, our digital agency working with clients across the US and UK to lead campaigns and partnerships of all kinds.
What You'll Do
- Own product design for Say So end-to-end - from problem framing and research through wireframes, prototypes, high-fidelity UI, and shipped features.
- Run tight user research feedback loops - design and execute usability tests, synthesize qualitative and quantitative feedback (surveys, in-app research tools, user interviews), and translate findings into concrete design decisions and roadmap input.
- Partner cross-functionally with Engineering to scope, prioritize, and ship features, balancing user needs with business and technical constraints.
- Contribute to and extend the design system, ensuring Say So's UI stays consistent with shared tokens, components, and brand variables while meeting Say So-specific needs.
- Present and defend design decisions to leadership and stakeholders, using research and data to support recommendations.
- Help build and refine our research infrastructure including in-app feedback tools, testing panels, and processes for continuously closing the loop between user insight and product iteration.
What We're Looking For
- Experience in product UX/UI design, ideally with consumer-facing digital products.
- Proven experience building and running user research feedback loops you can point to specific examples of research directly shaping shipped product decisions (not just research for its own sake).
- A portfolio that demonstrates end-to-end ownership: research, wireframing, prototyping, and high-fidelity UI.
- Deep fluency in Figma, including component libraries, variables/design tokens, and prototyping.
- Experience working within or contributing to a multi-brand or multi-product design system.
- Comfort working directly with Engineering to scope feasibility and ensure design fidelity through to production.
- Excellent communication skills - able to present research findings and design rationale clearly to both design peers and non-design stakeholders/leadership.
- A collaborative, low-ego approach paired with a strong point of view on craft.
- Experience with in-app research/testing tools (e. g., Sprig, Lyssna, or similar).
- Nice to Have
- Familiarity with gamification, streak-based, or habit-forming product mechanics.
- Experience designing for youth, Gen Z, or education/civic-engagement audiences.
- Illustration or motion design sensibility (e. g., Lottie), even if not a primary skill.
