Role
Who you are
- Have experience working as a Full-Stack or Backend-leaning Engineer within a product team, contributing to system design discussions and delivering production software
- Have hands-on experience designing and implementing data flow through software, from persistent storage to API endpoints, applying industry best practices for validation and reliability
- Have experience building and consuming APIs, ideally within a service-oriented architecture
- Are a collaborative and proactive communicator, comfortable working with engineers and non-engineers across the business
- Care about code quality, writing testable and maintainable code, and actively participating in code reviews — both receiving feedback and reviewing others’ work
What the job involves
- As part of a cross-functional team, contribute to projects by helping design systems, building proof of concepts, and delivering new service functionality — including APIs, data processing, and automation — while collaborating closely with Product and Clients
- Development and engineering primarily on backend services and web-application–hosted tools and systems within the 9fin platform
- Play an impactful role within project teams as an individual contributor, participating in code reviews, collaborating with peers, and contributing ideas during research and experimentation with new technologies
- Continually improve the 9fin codebase by taking opportunities to automate, refactor, and document where it’s most valuable
- Work across a diverse set of web platforms, including financial data modelling, access-control business logic, environmental and emissions data capture, integration with ML/AI prediction services, data visualisation, and automation systems

Our take
9fin’s initial aim was to solve the problem of extracting data out of financial documents. It quickly turned to AI, where computer vision tools can be deployed to find key financial data point quickly and automatically.
Its AI tools learn to understand the complicated legal clauses in contracts, automating a lot of the manual work that's usually involved in this space. 9fin also has a team of journalists and analysts who product news and analysis that help make sense of complex situations. The result is an integrated platform that debt capital market professionals can use to make quicker and better investment decisions.
9fin is used by leading banks, hedge funds, and asset managers around the world. The company has seen significant investment, the most recent of which will support the scaling of its team and expansion of its product into new asset classes, as well as helping it to grow its presence in the US, Latin America, and Asia Pacific.
