Senior Full Stack Engineer

Full Stack Developer | Node.js, TypeScript, React, AWS/Azure | Greenfield Client Platform, PE-Backed Wealth Manager Salary: £90,000 - £100,000Location: Bristol or LondonRemote working: One day a week in either office **A financial services background is NOT required; curiously, coming from outside the finance world will count in your favour.** I'm working with a private equity-backed wealth management firm who are hiring two Senior Full Stack Developers to build their new client platform from the ground up in AWS. They manage several billion in client assets for private clients and grow by buying smaller advice firms and moving them onto their own technology. They employ 180 people, have been established for decades, and they own the full suite: the advisers, the (future) tech platform, and the investment products they invest the money into. You will be building the client portal and portfolio management system that the whole business plan runs through. Node.js and TypeScript front and back, React on the front end, and the whole thing sits inside the AWS ecosystem: ECS on Fargate, Lambda, RDS for PostgreSQL, and an event-driven integration layer. There is no DevOps team, so infrastructure as code, pipelines and deployment sit with you rather than with someone else. You will own the data model too, alongside the Microsoft Dynamics CRM that stays as the system of record. The product direction is an AI-led client journey, building modules such as transcription of an adviser meeting, turned into a draft financial plan, and then into client reporting. There will be backend integration, because that is where the focus sits. Front end work will also be your responsibility again using AI agents as your engine. On AI, the client expects the majority of the code to be written by Claude Code or an equivalent tool. The reason they want seven years plus behind you is that someone has to know what good looks like, hold the framework and security standards, and tell the difference between working code and correct code. If you have spent years honing the craft and have decided you would rather direct the machine than type every line yourself, this is built for you.

The CTO has architected it and deliberately written none of it. He has opinions, has tested the modules he thinks will work, and will hand you the good and the bad of that on day one and ask what you think. He has done this before, at a firm whose assets grew more than tenfold in five years, so the playbook is tested rather than improvised. The team stays at two until the first phase ships and the MVP is proven, which means no hiding place and no committee. It also means you set the standards the next engineers inherit.
