Senior Interaction Designer (Motion, Animation, Mobile Product)
Location: London
Client: Chase UK
Working model: Onsite

The role:

We're seeking a Senior Interaction Designer to join Chase UK, JP Morgan's digital consumer bank, to help define the motion language, interaction patterns and iconography for an exciting new mobile product.

This isn't a traditional UI or Product Design role. We're looking for someone who obsesses over the details that elevate a product from functional to exceptional-timing, easing, choreography, micro-interactions and thoughtful motion that helps users understand what's happening at every step.

You'll work within a small, collaborative team of Product Designers, Engineers and Product Managers, owning the interaction and motion experience from concept through to production. Everything you create will contribute to a scalable design system and be shipped to users.

What you'll be doing:

You'll take ownership of the product's interaction and motion system, including:

• Defining motion principles, behaviours and animation standards across the product.
• Designing meaningful transitions that guide users naturally through key journeys.
• Creating loading, processing, confirmation and error state animations that clearly communicate system status.
• Designing polished micro-interactions including button feedback, selection states, expansion, reordering and navigation.
• Building a cohesive iconography system covering functional icons, status indicators and supporting illustrations.
• Producing high-fidelity prototypes that demonstrate timing, behaviour and interaction.
• Contributing to the design system with motion guidelines, reusable patterns and documentation.
• Working closely with engineers to ensure animations are performant and implemented as intended.

What we're looking for:

We're interested in people who have experience designing mobile product experiences, not just marketing or brand animation.

You'll ideally have:

• Strong experience in Interaction Design or Motion Design with a significant focus on mobile applications.
• An outstanding portfolio showcasing motion, transitions, interaction design and micro-interactions.
• Deep understanding of animation principles including timing, easing, sequencing and visual hierarchy.
• Experience creating motion systems and reusable interaction patterns.
• Strong iconography skills with experience designing consistent icon sets.
• Advanced Figma skills alongside one or more motion tools such as Rive, Lottie, After Effects, Principle or ProtoPie.
• Experience working with design systems and creating developer-ready specifications.
• Knowledge of accessibility best practice, including reduced-motion considerations.
• Experience collaborating closely with engineers throughout implementation.

About you:

• You notice when an animation feels just a little too slow.
• You know when an easing curve doesn't quite feel right.
• You care about craft but understand how to ship quickly.
• You're comfortable working in ambiguity, helping define patterns before they exist.
• Most importantly, you believe motion isn't decoration-it's a critical part of how great products communicate.

Why join us?

You'll have the opportunity to shape the interaction language of a brand-new product from the ground up. Rather than maintaining an established design system, you'll help define it.

If you're passionate about creating beautifully crafted mobile experiences and want your work to have a visible impact, we'd love to hear from you.

*To apply, please include your CV and a portfolio showcasing your interaction and motion design work. Applications without a portfolio are unlikely to be considered.*
