This is a rare opportunity to join a high-performance engineering team at the early stages of a major build, working on low-latency, high-throughput payment services that sit at the core of the firm's trading operations. The business is investing heavily in modernising its payments architecture, with all new development built in C# .NET and deployed on AWS. The focus is on speed, scalability, and resilience-designing systems capable of handling high transaction volumes with minimal latency and maximum reliability. You'll work closely with traders, quants, and senior engineers to help shape the next generation of the firm's payments infrastructure. As a Mid-Level Software Engineer, you will design and build new microservices, drive architectural decisions, and take ownership of key components across the payments lifecycle, including authorisation, routing, reconciliation, and settlement-all within a performance-critical trading environment. ## Related Videos - [Migrating half a million users to a new payment service provider](https://www.wearedevelopers.com/videos/730-migrating-half-a-million-users-to-a-new-payment-service-provider) - [Containers in the cloud - State of the Art in 2022](https://www.wearedevelopers.com/videos/410-containers-in-the-cloud-state-of-the-art-in-2022) - [Microservices: how to get started with Spring Boot and Kubernetes](https://www.wearedevelopers.com/videos/242-microservices-how-to-get-started-with-spring-boot-and-kubernetes) - [Swapping Low Latency Data Storage Under High Load](https://www.wearedevelopers.com/videos/746-swapping-low-latency-data-storage-under-high-load) - [Reliable scalability: How Amazon.com scales on AWS](https://www.wearedevelopers.com/videos/983-reliable-scalability-how-amazon-com-scales-on-aws) - [Cloud Chaos and Microservices Mayhem](https://www.wearedevelopers.com/videos/104-cloud-chaos-and-microservices-mayhem) ## Related Articles - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Highest Paying Tech Companies in Europe](https://www.wearedevelopers.com/magazine/162-highest-paying-tech-companies-in-europe) - [The Biggest German Tech Companies](https://www.wearedevelopers.com/magazine/424-the-biggest-german-tech-companies) - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Frontend Developer Salary in The UK](https://www.wearedevelopers.com/magazine/233-frontend-developer-salary-in-the-uk)
