Product Designer at Plasma in London, United Kingdom

Job description

• The design team at Plasma is small by choice. Two senior designers currently cover the whole of Plasma One, from core money movement flows through to the design system. You would be the third.
• Design is a first-class input here. It shapes product direction, technical tradeoffs, and whether people trust us with their money.
• You would help decide how design actually works: how decisions get made, how work is reviewed, how quality holds up under speed, and how a coherent system takes shape as the product grows. There is no process to inherit and no large team to hide inside. What you build becomes the standard.
• The team works closely with engineering and the growth team. Designers at Plasma are expected to think in systems, understand real constraints, and push for clarity where ambiguity is expensive. The bar is high, feedback is direct, and the impact is visible quickly.
• This suits someone who wants autonomy and responsibility, who wants to build the product that changes how money moves, and the team behind it.

Responsibilities

• Own the Plasma experience. Invent new features and shape how Plasma One feels to use, taking ideas from concept to launch. Turn the advantages of stablecoins and blockchain into experiences that make people’s financial lives better.
• Extend your abilities with AI. Use AI as a core tool to explore more ambitious ideas, build functional prototypes, and push what you can design and deliver.
• Bring ideas to life. Turn abstract concepts into working coded prototypes, then collaborate with engineers who share your attention to detail to bring them into production. Refine microinteractions, motion, and visual polish together.
• Evolve the design system. Build reusable components and interaction patterns that keep the product coherent as it grows, with design and implementation aligned.
• Learn from real use. Combine research, usability testing, and product data to discover opportunities and improve what you ship.

Requirements

• Substantial consumer product experience. Typically 6+ years in product design, including shipped native iOS and/or Android work and meaningful contributions to a design system.
• A portfolio with exceptional craft. Show us the details you refined, the reasoning behind them, and your contribution to the finished product. We want to understand your taste and how you decide when an experience is ready.
• Confidence with functional prototyping. You can make an idea tangible enough to test its behaviour and communicate the intended experience to engineers. Understanding or writing code is a bonus, not a requirement.
• Sound product judgment. You can explain how user evidence changed a decision, what you chose to prioritise, and what happened after launch. You are comfortable making progress when the brief is incomplete.
• Direct, thoughtful collaboration. You make your reasoning easy to follow, give specific feedback, and can disagree constructively. You know when to work independently and when to bring others into a decision.
