We are supporting a major multi-year technology transformation programme within a leading global financial markets organisation. As part of this initiative, we are looking for an experienced Solution Architect to play a critical role in modernising and migrating a suite of real-time, low-latency applications onto next-generation platforms.
As a Solution Architect, you will be responsible for designing end-to-end architectures for the migration of high-throughput, real-time applications from legacy environments to modern cloud and distributed platforms. You will define architectural standards, create migration blueprints, guide engineering teams, and ensure solutions meet strict performance, scalability, and resilience requirements.
What You’ll Be Working On
* Designing solution architectures for large-scale real-time application migration
* Creating technical designs, data flow diagrams, integration patterns, and migration routes
* Working closely with platform, engineering, infrastructure, and network teams
* Defining non-functional requirements: latency, throughput, availability, resilience
* Supporting architectural governance, design authority reviews, and technical decision-making
* Ensuring solutions align with enterprise architecture and cloud strategy
* Providing expert guidance during migration, cutover, and stabilisation phases
* Collaborating with global stakeholders and senior technical leaders
What We’re Looking For
* Experienced Solution / Technical Architect with real-time or low-latency systems exposure
* Strong background in distributed systems, messaging/streaming (Kafka, Solace, Tibco, 29West)
* Solid experience with cloud platforms (Azure/AWS), microservices, and Kubernetes
* Proven track record delivering application migrations or modernisation programmes
* Excellent architecture documentation, governance, and stakeholder engagement skills
* Financial services or complex enterprise experience is a strong advantage
