On behalf of a Leading financial services organisation, I am seeking an experienced System Architect and strong technologist to work on their market leading bespoke trading platform. The System Architect is responsible for defining and delivering the shared technical and architectural vision for the Agile Release Train (ART). As this is to work for a global business, there will be a requirement to work with geographically distributed teams and support global deployments as part of the overall architecture, therefore an individual with experience of working similar large scale environments with a strong background in ownership is essential.
The technology includes systems (applications, processes and information), shared infrastructure services, shared application services, and their effective integration and reuse across the business. The System Architect is working to align Feature teams to the Architecture roadmap and ensure the systems under development support the evolving business need and enables fast reliable implementation of value.
Responsibilities:
- Define and communicate the architecture vision, translating it into Epics, Features, and Stories.
- Ensure solutions align with business priorities, enterprise architecture, and evolving business needs.
- Support DevOps practices and the continuous delivery pipeline; contribute to release governance.
- Promote built-in quality, defining and managing non-functional requirements (NFRs).
- Collaborate with teams to evolve design, validate implementation, and drive sustainable practices.
- Maintain architecture documentation, system tools, and technical assets.
Experience/Skills required:
- Extensive experience in technical architecture and IT solution development (Front End, Back End, or Middleware) preferably within bespoke trading platforms.
- Track record of designing and delivering modern architectures with strong grasp of architectural principles.
- Experience working in Agile environments and understanding of the product life cycle.
- Exposure to multiple technologies and enterprise-scale environments.
- Strong technical leadership, with the ability to mentor and influence teams.
- Excellent analytical, communication, and stakeholder management skills.
- Hands-on enterprise systems development experience (Front End: JavaScript/REACT, Back End: Typescript – other languages considered).
- Proficiency in cloud platforms (AWS preferred; Azure/GCP), containerisation, and microservices.
- Strong knowledge of APIs, system integration, and DevOps (CI/CD, infrastructure-as-code, Git).
- Understanding of security practices (application, cloud, authentication, authorisation).
- Knowledge of Scaled Agile Framework (SAFe).
