Job Description: Senior Software Engineer
We are seeking a highly capable Senior Software Engineer to help design, build and evolve resilient, event-driven, cloud-distributed systems. This role is ideal for an engineer who combines deep technical expertise, strong computer science fundamentals, and commercial awareness - someone who not only understands how systems work, but what they are meant to do and why. The role requires a constructive, can-do approach and the ability to operate effectively in a fast-paced setting.
You will work across the full engineering lifecycle from system architecture and data modelling to implementation, testing and operational excellence. You will be encouraged to use modern AI-assisted tooling and continuously improve our platforms, while maintaining a pragmatic balance between innovation and delivery.
You will be part of a friendly and collaborative team responsible for post-trade and reporting software development. The role involves working closely with operations, fund accounting, and other teams across the business including senior management - there is no BA layer, you will gather requirements directly from the business, design solutions and own them end-to-end. In addition to project work, you will have regular opportunities to implement enhancements for both business and technology.
