MarketAxess is looking to digitally transform one of the world's largest financial markets by enabling the shift from analog, phone-based trading to a fully electronic marketplace. The company aims to make trading fixed-income more accessible, improving transparency, efficiency, and competition. The UI Platform team is responsible for building and maintaining the shared frontend infrastructure that powers all MarketAxess web applications, including data streaming technology, component libraries, developer tooling, CI/CD pipelines, and desktop integration capabilities.

- Strong architectural foundation, with practical experience designing and implementing cloud-native systems, event-driven architectures (e.g., Kafka), and scalable frontend/backend platforms.
- Experience working with desktop interoperability frameworks such as Interop.io (formerly Glue42 + Finsemble), OpenFin, or similar technologies, and an understanding of how they support multi-window, multi-app trading workflows.
- Comfort working across hybrid infrastructures (on-prem and cloud), with fluency in modern DevOps practices including CI/CD, monitoring, automated testing (e.g., Playwright, Cypress), and resilience engineering.
- Solid understanding of API and microservice architectures, structured and unstructured databases, and real-time systems — including logging, monitoring, and process automation.
