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.
• Frontend: React, Next.js, TypeScript, MUI
• 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.
