## Job description

## 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 The AI Engineering team at 9fin is building the next generation of AI capabilities that will power our products for years to come. We're looking for an Engineering Lead to lead the GenAI Platform team, building the shared foundations that enable product teams to develop and operate AI-powered products and agents. Reporting to the Head of AI, you'll own the team's development, technical direction and delivery. You'll shape the platform strategy and roadmap, working with product and engineering teams to understand their needs and decide where shared capabilities will have the greatest impact. You'll combine people leadership with strong engineering judgement, staying close to architecture and code while giving engineers the support and autonomy to do their best work. Every day is different, but here's an example of the kind of things you'll work on:

- Lead and grow the team through hiring, coaching, feedback and clear expectations for performance and development.
- Set the GenAI platform's direction and priorities, evaluate technical approaches and adapt the roadmap as product needs and evidence evolve.
- Own the delivery and operation of reliable, secure and scalable platform capabilities, balancing quality, performance, cost and speed of development.
- Make the GenAI platform easy for other engineers to adopt and extend through effective APIs, tooling, documentation and clear ownership.
- Partner with AI and evaluation specialists to establish how platform changes are tested, measured and released.
- Work with product, engineering and security colleagues to resolve dependencies, communicate trade-offs and turn emerging needs into sustainable capabilities.

What Makes This Role Different You'll join an evolving GenAI platform with substantial scope to shape its next stage. You'll help decide what the platform should provide, which approaches to adopt and how the team should grow as 9fin's AI ambitions develop. Your impact will reach across product teams. By building shared capabilities that engineers trust and choose to use, you'll help teams deliver AI products more quickly and operate them with confidence. You'll own both people leadership and technical direction, developing the team while remaining closely involved in the engineering decisions that determine the platform's success.

Production LLMs & Agentic AI

- Have built or operated complex LLM-powered applications or agent systems in production.
- Understand the challenges of non-deterministic systems, including evaluation, quality regressions, tool use, reliability, security and cost.

Backend, Cloud & Operations

- Have a strong backend or infrastructure engineering background, with ownership of distributed production systems in the cloud.
- Understand how to operate services reliably, including monitoring, incident response, performance and cost management.

Collaboration & Technical Leadership

- Have the technical depth to review designs and code, assess alternatives and help engineers work through difficult problems.
- Communicate trade-offs clearly, build effective partnerships across teams and use evidence to make decisions in ambiguous situations.

- Event-driven architectures or long-running asynchronous workloads
- Secure execution environments and access controls
- AI evaluation, experimentation or observability
