Senior Software Engineer

Senior Python Developer

Location: Remote (London office available)

Type: Full-time

Were looking for an experienced Senior Python Developer to join a small, highly skilled engineering team building a next-generation Financial Services Regulatory Compliance platform.

Youll 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 platforms 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.
