Senior Product Manager - Platform & Developer Experience

About 9fin

9fin is the AI platform powering global debt markets — the world’s largest asset class at over $145 trillion.

Debt markets are vast, global, and mission-critical, yet still run on fragmented data, PDFs, and manual workflows. 9fin replaces this broken infrastructure with a single platform that centralises proprietary credit data, deep analysis, and high-value workflows across global markets.

Today, 9fin powers teams at 300+ blue-chip institutions worldwide, including global banks, asset managers, private equity firms, law firms, and advisors. The business is scaling at exceptional speed, with rapid expansion in the US and best-in-class retention driven by deep workflow adoption.

We’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.

The Opportunity

Our 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.

Today, 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.

You 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.

Key responsibilities:

Product Strategy & Execution

• Strategy: Collaboratively create and champion a clear product vision and strategy for the platform product squad.

• Problem definition & structured thinking: Synthesise insights from engineering surveys, interviews, and usage data to craft clear problem statements, articulating root causes in a structured way.

• Discovery: Run structured discovery with internal engineering customers - interviews, usage analysis, survey synthesis - to understand developer workflows, identify friction, and build confidence before investing.

• Impact 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.

• Measuring success: Proactively identify and track metrics that capture platform value and make the impact of platform work visible across the engineering org.

Team Leadership & Communication

• Team 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.

• Communication: 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.

• Influence: 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.

• Stakeholder 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.

About You

This role will be a great fit if you:

• You 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.

• You 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.

• You'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.

• You'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.

• A software engineering or platform engineering background is a significant plus.
