Job description

Overview

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.

Please provide a link to your portfolio in your resume or in your work experiences, including the password if applicable. Applications without a portfolio will not be considered.

About us:

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.

What You’ll Work On

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

Who We’re Looking For

We are seeking designers who thrive across the full spectrum of product design—hands-on and strategic, analytical and creative, global and collaborative.

• Experience – 4+ years of product design experience with a portfolio that demonstrates excellence in interaction and visual design
• Language – Excellent written and spoken English; this is a 100% English-speaking role
• Fluency Across Stages – Skilled in research, synthesis, strategy, and UX/UI delivery; confident facilitating workshops and guiding client conversations
• AI IQ – Strong understanding of AI as both design material and system architecture. If you’d rate yourself a 4 or 5 (on a 1–5 scale), we want to talk. Skills in vibe coding, prompt engineering, agentic architectures, and rapid prototyping workflows are highly valued
• Systems Thinking – Ability to design for the whole: ecosystems, organizations, and interactions that span channels and services
• Business Acumen – Able to frame trade-offs and connect design decisions to measurable outcomes
• Craft – Proficient in Figma and modern design tools; capable of building modular, scalable systems and prototypes that bring clarity to complexity
• Collaboration – Comfortable working across time zones in distributed teams; eager to learn from peers, share knowledge, and co-create with clients as true partners
• Attributes – Curious, adaptable, empathetic, and a critical thinker who can clearly defend design decisions
• Mobility – Willingness to travel occasionally for client engagements or team activities (less than 20%)

Additional Skills

• Planning and conducting user, customer, and stakeholder interviews; running validation sessions and usability testing
• Performing heuristic evaluations and expert reviews
• Analyzing and synthesizing user research findings
• Creating and communicating mental models, personas, flows, journeys, and other information architecture deliverables
• Storytelling and narrative development to communicate design concepts, inspire stakeholders, and build conviction
• Experimenting with motion design, 3D, AI, or emerging technologies

Designers at Momentum aren’t locked into roles—they are empowered to shape outcomes across industries and touchpoints. No year is the same.

You’ll gain:

• Opportunities to influence products and services used by millions worldwide
• Experience across startups, scale-ups, and Fortune 500 companies
• Exposure to industries ranging from health to climate to finance
• Collaboration with colleagues and clients across continents
• The chance to experiment at the forefront of AI, design, and technology

The Perks:

• Create Impact – Influence real-world products and services at scale
• Work Across Boundaries – Expand your range with projects spanning industries and markets
• Collaborate Globally – Learn how design operates across cultures and contexts
• Experiment with AI – Push the edges of how AI transforms discovery, design, and delivery
• Grow Continuously – Learn from peers in design, data, engineering, and business strategy

Competitive salary and benefits, diverse projects, and opportunities for global collaboration are part of the package. More importantly, you’ll join a culture where design is treated as a core driver of business value and human experience.

If you’re a designer who thrives across the full arc of product design—and who brings both craft and systems thinking—we’d like to meet you.
