Senior Full-Stack Developer (React / Python) – Remote (UK)
We’re looking for an experienced Senior Full-Stack Developer to join our small, highly skilled engineering team building a next-generation Financial Services Regulatory Compliance platform.
You’ll work on complex systems that combine an elegant, data-driven frontend with powerful Python APIs and AI-backed analytics — helping financial institutions make sense of tens of thousands of regulatory documents and millions of news items.
Key Responsibilities
* Design, develop, and maintain modern, scalable React applications integrated with Python-based APIs.
* Take ownership of the frontend architecture, implementing clean, reusable components and responsive layouts in Next.js / React.
* Collaborate with backend engineers to shape and optimise FastAPI endpoints for data-heavy, real-time interfaces.
* Refactor and enhance existing UI components for performance, accessibility, and maintainability.
* Contribute to overall system design, ensuring smooth integration between frontend, backend, and AI/LLM modules.
* Participate in sprint planning, code reviews, and architectural discussions as part of a tight-knit, agile team.
About You
* Strong experience building complex SPAs with React (and ideally Next.js).
* Proficient in Python for backend integration — experience with FastAPI or Flask a plus.
* Strong understanding of RESTful APIs, asynchronous programming, and frontend performance optimisation.
* Comfortable working across the stack, contributing to both UI and backend logic.
* Experience with cloud-hosted environments (Azure, GCP, or AWS).
* Familiarity with AI/ML or LLM-driven systems is beneficial but not required.
* Knowledge of financial services or regulatory technology is a bonus, but not essential.
Tech Stack
* Frontend: React, Next.js, TypeScript, MUI
* Backend: Python (FastAPI / Flask)
* Database: MongoDB
* Cloud: Azure (moving to GCP; AWS possible)
* Other: Redis, Docker, GitHub Actions
What We Offer
* Flexible remote working (London office available for optional collaboration).
* The chance to work on a technically challenging, high-impact AI-driven platform.
* A collaborative, low-bureaucracy environment where your input directly shapes the product.
