About us

We're a fast growing fin-tech startup making waves in the lending industry. We've built an innovative product that has just been launched into market and now we're looking to go to the next level. We're well funded with backing from heavy weights in the industry. We're not just looking to be disruptive but to take over.

About the role

We're looking for a strong senior, back-end focused engineer. Our stack is predominantly TypeScript/Node, and you'll be working with us on many different elements of our platform, from:

• integrating AI into our broker platform,
• building out our APIs and corresponding SDKs, and integrating with commercial partners,
• dabbling in our Electron-based desktop application and (React) web application,
• working on UI automation over websockets / CDP,
• changing our event-driven durable execution pipelines (Inngest),
• provisioning infrastructure across Cloudflare and AWS

Being a small team, we're used to jumping on all ends of the stack to tackle our priorities effectively, and we don't tend to have static, pigeon-holed responsibilities.

We make heavy use of AI to write code at Financeable, and our team have experience across multiple harnesses including Claude/Codex/Amp/Cursor/OpenCode etc, we're looking for similarly curious engineers with opinions about the tools they use.

You should have:

• 5+ years experience as a developer
• Extensive experience working with TypeScript, knowledge of other languages like Go greatly appreciated.
• Knowledge of observability tools, vendors and ecosystem. We utilise Honeycomb.io, but knowledge of OTEL generally is highly regarded.
• Infrastructure-as-code experience is a must - we provision application infrastructure exclusively via IAC. We utilise a mixture of Serverless Stack and Alchemy, across AWS and Cloudflare.
• Experience and knowledge regarding API management (versioning, documentation) is a plus.

Nice to have:

• Experience working in Finance/Banking
• Experience working with distributed/remote teams
• Experience with feature toggling
• Knowledge of emerging trends like Local First, Durable Compute, LLMs generally.
• Domain Driven Design knowledge is appreciated but not essential.
• Opinionated about error handling: do you prefer treating errors as values or throwing exceptions? How do you ensure your error output meets your API spec?

Why join us

• Very competitive salary
• Relaxed, flexible and accommodating working environment
• Equity opportunities
• Free tech - keep the equipment we buy you!
• Get in on the ground level of a fast growing company
• Make your mark - you'll have direct influence on the product
• We're tons of fun - loads of team, community and industry events on the calendar
