About us
Lumen Cards is a new consumer lending business preparing to launch its first credit card to the UK consumer market in H1 2026. Our management team brings over 20 years of experience each in consumer finance, and we operate from two locations: London Kings Cross, and Leicester.
At Lumen, we approach consumer lending with a “do the right thing” mindset. Our goal is to provide credit that helps customers solve real-life problems.
We’re committed to building a great place to work. We want every colleague to feel valued, empowered and impactful. We celebrate shared success, support one another through challenges and foster a culture where ideas are welcomed, and collaboration is second nature. When things go wrong, we don’t point fingers, but we pull together to find a way forward.
Role Overview
You will be joining Lumen at an exciting time, as we prepare to launch first credit card product. We are looking for a credit & commercial manager to lead the development and optimisation of our credit strategy from day one.
This is a key role in an early-stage fintech, where you’ll be the central point of expertise for credit risk decisioning, responsible for shaping credit strategy for acquisitions, managing in-life credit performance, and driving commercial outcomes. You’ll design and implement, data-driven credit strategies that balance growth, risk, and customer outcomes.
In a new lending business and ever changing macro-economic environment, credit dynamics evolve quickly, and your role will be critical in ensuring our strategies are proactive, responsive, and resilient. You’ll work across pricing, credit limits, affordability, and portfolio optimisation, collaborating with product, tech, and data teams to embed credit thinking into every part of the customer journey.
We are a small but rapidly growing business. The role holder will be expected to be a hands-on contributor to the business while also helping mentor new joiners as we grow. This is a unique opportunity to help build a responsible lending business from its earliest stages, influence strategic decisions, and make a meaningful impact on how credit is delivered to UK consumers.
