Product Design Lead About Monument Were building something genuinely rare: a financial brand designed for the mass affluent: the professionals, entrepreneurs and ambitious savers that traditional banks have systematically underserved for decades. We exist to make managing wealth simpler, smarter and more human, treating every clients wealth with the same care as if it were our own. We have over £7 billion in client deposits, a fresh funding round and a place on the Future Fifty, the UKs top pre-IPO companies.

The Opportunity Savings is Monuments most established product. We have product-market fit. The challenge now is scale. Were targeting £10 billion in deposits this year and £30 billion by the end of 2030. This is a 1-to-100 role, not a 0-to-1 role. Were not searching for product-market fit. Were engineering the systems, experiences and design decisions that turn a proven product into a category-defining one.

For the right designer, this is one of the most compelling roles in UK fintech: genuine scale, a discerning client base, real commercial stakes and the mandate to do it properly.

What Youll Do Own design for the Savings frontier. Work closely with the Product Lead to set direction. You are the design authority, from research and concept through to shipped, scaled product. Design for scale, not novelty.

At this stage, the work is less about invention and more about rigour: removing friction, increasing activation, improving retention and turning one-time depositors into long-term clients. Translate complexity into clarity.

Savings products for the mass affluent sit at the intersection of trust, emotional significance and financial sophistication. Your craft is making that feel effortless. Build and run a fast experimentation cadence.

Hypothesis-led, data-validated. You design the test as carefully as the final product. Work with evidence, not opinion.

Let client data, usability research and commercial outcomes shape decisions. Adapt fast when the evidence changes. Partner across functions.

Collaborate with Engineering, Compliance, Data and Marketing to ship work that holds together end to end. Use AI to move faster.

Leverage AI-enabled design tools to accelerate iteration, reduce non-core work and amplify your output. Raise the bar across the design team.

Share learnings, contribute to shared systems and help Monuments design practice grow with the business. The Challenges Youll Tackle Scaling without breaking trust.

The mass affluent chose Monument for a reason. Every change to the product must reinforce, not erode, the confidence that brought them here. Turning activation into lifetime value.

Getting clients to open an account is the start. Designing the journey that keeps them engaged, deepens their relationship and grows their deposits over time is the actual challenge. Moving at pace inside a regulated environment.

Compliance and experimentation must move together. You know how to navigate that without using it as an excuse to slow down. Finding the next product frontier. Savings accounts are well understood. The opportunity is to look beyond the obvious and design genuinely new product forms that give the mass affluent better ways to grow and manage their money. The Mindset Scale-first thinking.

You have moved a product from working to dominant. You know what changes at 10x and 100x, and you design for it. Radical ownership.

Accountable for design outcomes, not design activity. You measure yourself by what ships and what it does in the market. Craft without compromise.

Fast and polished are not in conflict for you. Quality is the default, not the exception. Bias to action.

You show progress through product, not Figma files. Intellectual humility.

Half your assumptions will be wrong. You love finding out which half. What You Bring Proven experience scaling a digital product from established PMF to significant scale. This is a 1-to-100 role and we will look for evidence of that Full-stack design skills: research, interaction design, visual…
