. As a technology-driven organization, we value individuals who embrace innovation and are eager to leverage emerging technologies, including AI, to improve efficiency, enhance decision-making, and deliver better outcomes for clients and colleagues.

We believe the greatest impact comes from combining technological capabilities with human expertise, judgment, and accountability Group Details To capitalize on our success and continued growth plans, we are seeking an AI Platform Engineer to help build and scale Tradeweb’s enterprise AI capabilities.

You will build and run the shared AI platform layer on AWS Bedrock that engineering and business teams use to deliver AI safely and at scale: model gateways, Model Context Protocol (MCP) servers, evaluation and observability tooling, cost controls and secure configuration templates for AI developer tooling. You will also work hands-on alongside internal teams, including Risk, Cyber Security and Internal Audit, to turn their workflows into working AI solutions on the platform.

This is not a research role: you will build on foundation models through managed services rather than train models from scratch. As a member of the Technology team, this role will work with subject matter experts across engineering, infrastructure, cloud, data, information security, risk, compliance and the business, and will directly shape how AI is adopted across the firm. The role works closely with our Security Architecture and Cyber Security teams, so a working understanding of application, platform and cyber security is important.

We look to hire people who are comfortable working with minimal supervision as part of a team that has consistently delivered ground-breaking and innovative solutions in one of the most exciting and fast-moving areas of the financial markets. We need people who can prioritize, move quickly from idea to production, and effectively articulate complex issues to technical and non-technical team members. This role is based in our London office with a hybrid working arrangement.
