Senior Software Engineer

Python Developer – GenAI Project Tier-One Investment Bank (without the politics) London £90,000-£120,000 + benefits Are you a seasoned Python Developer looking to work on cutting-edge Generative AI projects without the bureaucracy of a typical banking role? A developer-led software consultancy is partnering with a tier-one investment bank on a critical project, and we’re seeking engineers to work on global-scale technology solutions with massive impact—without the red tape. The consultancy places a huge emphasis on quality and software engineering best practices and only hires the best who share these high standards. This is a unique opportunity to work in the banking sector without being bogged down by the typical politics. You’ll focus purely on engineering, leveraging modern technologies and cloud-native principles to build secure, scalable platforms using open-source tools. The work includes core engineering, API development, and building Python-based frameworks that enable safe and efficient use of generative AI across the bank’s ecosystem. What You’ll Do: Develop robust, reusable Python code, building libraries and frameworks to safely integrate GenAI technologies into the bank’s infrastructure. Work on key APIs that consume data used by GenAI tools, enabling innovations like generating database queries and client reports from free-text inputs. Design and develop globally scaled backends using microservices or distributed systems. Deploy Python applications using Docker and Kubernetes, contributing to the development of cloud-native, scalable systems. Tackle PDF parsing and OCR (optical character recognition) challenges. Build data pipelines and handle large-scale, enterprise-level systems. Engage in research on new AI/ML tools, and present your findings to the team. What You Bring: 5+ years of Python programming experience (Django preferred). A keen interest and some commercial experience in AI/ML and emerging GenAI technologies. Experience with DevOps tools like Docker and Kubernetes (preferred but not essential). Experience working with systems at scale, handling large datasets across regions. Strong communication skills, able to articulate complex issues to both technical and non-technical stakeholders. The ability to drive ideas and solve challenges within a large, matrixed organization. Why You’ll Love This Role: Work on transformative AI projects without needing prior banking experience. No bureaucracy—focus on building and innovating. Experiment with cutting-edge LLMs (switching between OpenAI, Google Vertex AI, etc.) and build AI tools that will shape the future of finance. Flexibility to work in the office Monday, Wednesday, and Friday while engaging with groundbreaking projects. Ready to shape the future of AI in banking without getting caught up in banking politics? Apply now and become part of a team that’s driving innovation on a global scale.
