Together, we offer faster time-to-market, modular services, and a modern customer experience that helps financial service providers stay competitive and respond more flexibly in a changing market. Your Mission As a Product Manager in the Investing domain, you will contribute to the product scope our largest partners depend on, as well as our side of the joint dwpbank x lemon.markets suite. Your remit will include working with some of the biggest financial institutions in Europe to deliver core capabilities. These include trading mechanics, tax, corporate actions, and the investing capabilities we're building jointly with dwpbank. You will scope them, prioritise them, and deliver them. Reporting to the Senior Product Manager, Investing, you'll drive complex, multi-stakeholder commitments end-to-end. You'll work across internal teams at lemon.markets, our largest partners, and dwpbank counterparts in the group. Success looks like partners shipping compliant products on our infrastructure without us being the bottleneck. In this role you will: • Own the roadmap for a set of partner-critical Investing capabilities, from problem framing through to launch, adoption, and iteration. • Be embedded in a cross-functional crew including operations and engineering, while engaging with other product teams, solutions engineering, external partners, and colleagues in risk, finance, and compliance. • Prioritise commitments against the domain strategy using quantitative and qualitative evidence, and share your trade-offs internally and externally. • Ensure that any partner-specific integrations have longevity within our platform. • Engage directly with enterprise partners and prospects - scope requirements, negotiate delivery, prioritise. • Work with dwpbank counterparts on joint product opportunities, translating between two organisations with different ways of working. • Propose forward-looking solutions that outlive the immediate ask, rather than one-off fixes for the loudest partner. • Track market and regulatory developments in our space, and bring the insights back to the team. You’ll be successful in this role if: • You have at least 2-3 years of product experience, independently shipping highly complex products. • You are comfortable with ambiguity - you can define a problem space, structure it, and move forward without waiting for someone else to hand you a spec. • You argue your position based on data and evidence, and iterate when the evidence changes. • You can express yourself in writing. Documentation, decisions, specs, partner comms - clear writing is a core part of the job. • You use AI tools in your day-to-day work and are comfortable pushing what they can do. • You are professionally fluent in English and German. • Experience in regulated fintech / brokerag
