The business is scaling at exceptional speed, with rapid expansion in the US and best-in-class retention driven by deep workflow adoption.\nWe’re at a defining inflection point. With proven product-market fit and strong, global market pull, 9fin is accelerating toward becoming the category-defining platform for debt markets worldwide.\nThe Opportunity\nOur Platform engineering team is growing up. Two engineering teams, Developer Experience and Cloud Infrastructure, build the foundations every 9fin engineer and product squad relies on. We now need a senior Product Manager to sit across both and bring product discipline to how the platform is shaped.\nToday, Platform runs on speed and engineering instinct. You will help it work more like a product team. You will own the upfront work of problem definition, internal user research, prioritisation and success criteria, so engineers can focus on building the right things. Engineers are your customers: you will interview them, compare solutions, synthesise what you learn, and turn it into a clear roadmap. You will also own quarterly strategy and priorities planning across both teams, balancing operational and support demand against building the self-service platform of the future.\nYou will work closely with two engineering leads and their teams, and partner with product squads across the organisation who depend on the platform. Day-to-day triage will largely stay with platform engineers, so you can focus on the decisions that matter most. This is a high-autonomy role with direct access to engineering leadership and real scope to define what “platform as a product” means at 9fin. You will also make the value of platform work visible, using data to show where it makes teams more effective and celebrating the wins.\nKey responsibilities:\nProduct Strategy & Execution\nStrategy: Collaboratively create and champion a clear product vision and strategy for the platform product squad.\n\nProblem definition & structured thinking: Synthesise insights from engineering surveys, interviews, and usage data to craft clear problem statements, articulating root causes in a structured way.\n\nDiscovery: Run structured discovery with internal engineering customers - interviews, usage analysis, survey synthesis - to understand developer workflows, identify friction, and build confidence before investing.\n\nImpact driven: Define and align the team around key outcomes and effectively prioritise across Dev Experience and Cloud Infrastructure, distinguishing urgent requests from long-term investments that benefit multiple teams.\n\nMeasuring success: Proactively identify and track metrics that capture platform value and make the impact of platform work visible across the engineering org.\n\nTeam Leadership & Communication\nTeam Success: Create a collaborative environment across Dev Experience and Cloud Infrastructure, providing wider context and clear goals so engineers can do their best work. Celebrate platform wins and build a culture where engineers trust the roadmap.\n\nCommunication: Ensure all people involved are aware of the team's strategy, initiatives, and progress. You must be able to effectively communicate complicated technical concepts to non-technical audiences.\n\nInfluence: Build strong relationships to empower your squads to achieve the desired outcome, often by influencing stakeholders outside your team - including product and feature teams who depend on you.\n\nStakeholder Management: Work with internal engineering stakeholders to gather the right input, ensuring they have the information to effectively represent the platform team within their own areas.\n\nAbout You\nThis role will be a great fit if you:\nYou are an experienced platform product manager. You have solid experience in platform product management, preferably in the FinTech or B2B SaaS space, and you're eager to solve internal platform users' problems, drive adoption, and measure impact.\n\nYou have technical and analytical fluency. You understand developer workflows well enough to investigate problems independently, interrogate data, and challenge assumptions with evidence. You have an outstanding ability to think on your feet and tackle intellectually challenging problems. You are highly analytical and comfortable using data to make decisions.\n\nYou've got a keen interest in AI. You actively use AI in your day-to-day, attend courses, follow industry developments, and attend relevant talks about AI. You are ready to work closely with technical teams to understand different approaches and translate product goals into clear platform requirements.\n\nYou're a collaborative leader. You have an empathetic leadership style and build strong, effective relationships. You love working autonomously but are able to earn the trust of others with a collaborative style. You are a great prioritiser, not afraid to say no, and excel at managing stakeholders while also being confident in voicing your own opinions and challenging others.\n\nA software engineering or platform engineering background is a significant plus.\n\nBenefits\nWe’re a scaling start up, and we enjoy sharing our success, when the company succeeds, we always reinvest that in our people. We also offer huge amounts of responsibility, an abundance of opportunity for growth and a platform to truly excel.\nFinancial & Insurance\nCompetitive Salary (our salary bands are benchmarked at the top end of the market)\n\nEquity options\n\nPension (your minimum contributions are 4% with 9fin matching up to 7%)\n\nPrivate Medical Insurance\n\nPaid sick leave with Income Protection for long periods of illness\n\nGroup Life Assurance\n\nSeason Ticket Loan & Cycle to Work schemes\n\nTime off\n25 holiday days per year\n\nLocal public holidays (with the ability to exchange them for alternative days)\n\nWork abroad for up to 3 months a year\n\n1 month paid sabbatical after 5 years of service\n\nEnhanced parental leave & flexible working arrangements available\n\nTraining & Culture\nProfessional learning and development budget\n\nQuarterly team socials\n\nSummer and Winter company social events\n\nHybrid Policy\n9fin is a hybrid company, and the office is a regular part of how we work. From January 2027, all employees will work from their designated 9fin office on Tuesdays and Wednesdays. Some teams may be asked to be in the office more often, where the nature of their work calls for it. For the rest of the week, you may work from wherever works best for you and your team. Your Talent Partner will share hybrid working details for this role.\n9fin is an equal opportunities employer\nAt 9fin we are dedicated to building and promoting a fair and inclusive workplace where everyone can reach their full potential and truly belong.
