Job description

Location: Central London (on site)Experience: 2+ years## About FundflowFundflow is building the first AI-native investment bank for the innovation economy. Founded by Goldman alumni, we combine vast deal experience with AI-first execution to deliver best-in-class capital market services to the tech ecosystem.Where digital banks redefined retail banking for good, investment banking has barely evolved. Wall Street still runs on armies of analysts and PowerPoints to deliver a service that is slow, costly, and outdated - keeping great advice out of reach for most founders.Our mission is to change this.Purpose-built from real deal experience, our AI platform automates the manual work in credit advisory and turns deal data into actionable intelligence. This enables our bankers to deliver smarter advice, faster execution, and better outcomes for our clients.And it's working. Fundflow has already raised over $1Bn in private credit for startups - from $10M venture debt rounds to $200M pre-IPO facilities - establishing Fundflow as a trusted partner to founders and lenders alike. We're now growing our investment banking team to scale this impact across Europe.Read our story in .## Job DescriptionWe're looking for an exceptional engineer who wants to drag an archaic industry into the AI era - side by side with the bankers who live it every day.As our Founding Engineer, you'll be Fundflow's first dedicated engineering hire, working directly with the founders to build the platform our bankers run deals on. The engineering function is yours to create: what we build, how we build it, and the standards we build it to. The founders set the direction - you own everything from there, acting as your own product manager from idea to production.Your users sit ten feet away, work on live transactions, and will tell you within hours whether what you shipped made their deal faster. Come build the future of investment banking with us!## What You Will Do* Build side by side with our bankers. This is an in-house forward-deployed engineer role in all but name: sit with the deal team, find where a live transaction slows down, and own the fix from idea to deployment - shipped today, used on a live deal tomorrow.* Build across the entire stack. You will work across frontend, backend, and data as one product.* Put AI to work on real deals. Design and ship AI-powered workflows where models handle the grunt work and bankers apply judgment - then measure whether it actually made deals faster.* Set up the engineering function. Tooling, standards, culture, and how we ship: you'll define them from the ground up, not inherit them.## What we are looking for* Building Experience: 2+ years building and shipping production software - ideally in TypeScript - that real users depend on.* Generalist Range: You love building across the stack and pick up whatever the next most important problem needs.* Product Sense: Comfortable in ambiguous, unstructured startup environments - given direction, you act as your own product manager and make good calls without a spec.* AI-Native Instincts: Hands-on experience building with LLMs, and strong opinions about where they work and where they don't. Finance experience is a bonus, not a requirement.## Why join usWe're building investment banking the way it should exist: efficient, intelligent, and genuinely enjoyable. No politics. No pointless process. If something can be automated, we automate it. If something requires real thinking, we do it properly with AI at our side.We trust smart people to deliver great work and reward them like owners. Founding equity means when the company wins, you win. Improve our workflows, and you'll share in the value you create. Titles don't matter here. Impact does.Join early, automate a trillion-dollar industry from inside it, and help rebuild how deals get done - with the people doing the deals sitting next to you.## How to applyApply with the application form and tell us about the most impressive thing you've built.
