Senior Python Developer
Location: Remote (London office available)
Type: Full-time
We’re looking for an experienced Senior Python Developer to join a small, highly skilled engineering team building a next-generation Financial Services Regulatory Compliance platform.
You’ll work on complex systems that process and analyse tens of thousands of regulatory documents and millions of regulatory news items leveraging cutting-edge AI and LLM technologies to deliver actionable insights.
Key Responsibilities
* Design, develop, and maintain scalable backend systems using Python and FastAPI in an API-first architecture.
* Refactor and rebuild complex components of the existing platform to improve performance, scalability, and maintainability.
* Take ownership of key system modules while collaborating closely with a small, agile team of three engineers.
* Contribute to the evolution of the platform’s architecture as we transition cloud infrastructure from Azure to GCP (and potentially AWS).
* Integrate and optimise AI/LLM-based components to enhance automation and intelligence across the platform.
* Work cross-functionally with product and data teams to deliver new features and enhance existing capabilities.
About You
* Extensive experience with Python, particularly in API-first development (FastAPI preferred).
* Strong understanding of modern software architecture, system refactoring, and scalability improvements.
* Comfortable working autonomously and taking ownership of major system areas, while maintaining a hands-on, collaborative approach to team projects.
* Experience with LLMs or AI/ML-driven systems is highly desirable.
* Knowledge of Knowledge Graphs, RDF, or OWL would be an advantage, but is not required.
* Familiarity with financial services or regulatory technology is beneficial, though not essential.
Tech Stack
* Backend: Python (FastAPI)
* Frontend: Next.js / React
* Database: MongoDB
* Caching/Queueing: Redis
* Cloud: Azure (moving to GCP; AWS possible in the future)
What We Offer
* Flexible remote working (London office available for optional in-person 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.
