Senior Product Designer (Contract or FTE)

Momentum is not a place for narrow specialists. We are a true product design group: our designers move fluidly across the entire process—from hands-on research and insight gathering, to framing experience strategies, leading client workshops, crafting UX/UI systems, and embedding AI-driven thinking into product and service ecosystems.

As a Senior Product Designer, you will shape outcomes at the intersection of business analysis, service design, and digital product experience. This requires craft, confidence, and the ability to guide both teams and clients through complexity.

We are a global company, with clients and team members distributed across time zones, so flexibility in how and when you collaborate is essential for our integrated approach to succeed. This position can be hybrid or remote, but candidates must be available during working hours aligned with our London office (GMT/BST time zone). Full-time work from the London office is also an option. We welcome both full-time employees and contractors, and qualified international candidates within reasonable time zones are encouraged to apply.

Momentum helps global brands, fast-moving startups, and category leaders solve high-impact business challenges through product and service design. 

Our work extends beyond digital interfaces. We design multi-channel, multi-touch experiences that integrate brand, experience, and value across physical, digital, and human interactions. 

We are collaborators first—partnering with clients in workshops, research, and prototyping to uncover opportunities, reduce risk, and drive innovation. Each engagement is unique, but all are grounded in the same belief: design should create clarity, confidence, and transformation. 

Designers at Momentum move across industries, problems, and horizons. As a Senior Product Designer, you may help: 

• Shape the future of mobility, exploring how people, vehicles, and services connect in new ecosystems 
• Reimagine neurosurgical planning through 3D, VR, AR, and AI-powered tools that support both pre-operative planning and live surgical procedures 
• Architect end-to-end telecom service experiences across digital and physical touchpoints 
• Build intelligent digital agents to combat misinformation in global health 
• Visualize and model strategies for billion-dollar venture portfolios, with AI-augmented insights 
• Design multi-channel healthcare journeys for patients, providers, and caregivers—personalized through AI orchestration and automation 
• Shape carbon-positive experiences through climate and sustainability platforms 
• Explore the frontier of AI-powered experiences—from automation to augmentation and beyond
