Solutions Architect

Job description

A major financial market infrastructure is undergoing a multi-year transformation, moving from legacy COBOL-based systems on HPE NonStop to a modern, event-driven, Java-based architecture.

This is not a simple migration. It’s a fundamental shift toward scalable, platform-independent systems built on Linux and containerised environments.

You’ll join a Solutions Architecture team within a Software Engineering function, working across both strategic design and hands-on delivery.

Your focus will be a large-scale transformation programme, shaping how legacy platforms evolve into a modern, distributed ecosystem.

What you’ll be doing

• Design end-to-end solution architectures across complex programmes
• Translate business and technical requirements into scalable designs
• Act as the bridge between Enterprise Architecture and engineering teams
• Define reusable architecture patterns and contribute to engineering standards
• Collaborate with security, infrastructure, and delivery teams
• Lead or support proof-of-concepts and prototype development
• Provide technical leadership, including hands-on Java development where needed
• Present architectural solutions to a range of stakeholders
• Ensure consistency, compliance, and quality across systems

What you bring

Core experience:

• Proven background in solution architecture across full delivery lifecycles
• Experience delivering complex, enterprise-scale systems
• Strong Java and object-oriented design expertise
• Experience with event-driven architectures (e.g. Kafka)

Nice to have:

• Microservices or SOA architectures
• Containerisation and OpenShift
• Database design (Oracle, SQL Server, etc.)
• Experience in regulated or financial environments

Interviews will commence swiftly.
