Solutions/Integration Architect

Role Outline

We are looking for an experienced Integration / Solution Architect to support the modernisation of a complex application landscape spanning legacy on-premise systems, cloud platforms and third-party solutions.

The initial and primary focus will be a major legacy platform replacement programme, requiring the architect to understand the current application, integration and data landscape and use this to shape target and transition architectures.

Alongside this, the role will work across the wider technology landscape, ensuring solutions align with broader architecture, integration and modernisation goals.

We are looking for someone equally comfortable understanding how complex legacy systems work today and designing how the landscape should work tomorrow.

Key Responsibilities

• Investigate and document the as-is application, integration and data landscape, including legacy systems, interfaces, dependencies and data flows.
• Work with business and IT stakeholders to understand business processes, system behaviours and non-functional requirements.
• Identify technical debt, hidden dependencies and legacy constraints that may impact transformation.
• Define target and transition architectures, including interim states where legacy and new solutions need to coexist.
• Assess internal and vendor solution designs against the existing landscape and strategic architecture direction.
• Develop integration approaches covering APIs, events, messaging, batch, files and existing legacy patterns.
• Support data migration, reconciliation, coexistence, cutover and legacy decommissioning.
• Translate architecture decisions into clear implementation steps, dependencies and work packages.
• Maintain clear architecture documentation covering applications, integrations, data flows, transition states and key decisions.
• Work closely with internal teams and external partners to challenge proposals, resolve architectural issues and align solutions.
• Contribute to architecture and modernisation initiatives across the wider technology landscape, beyond the primary programme.

Required Technical Skills & Experience

Cloud & Infrastructure

• Cloud-native experience, working primarily in AWS, but also Azure or GCP
• Leveraging and supporting development of enterprise platforms
• Experience working across multiple regions, implementing high availability and disaster recovery strategies
• Strong network and routing knowledge, understanding gateways, reverse proxies, VPNs, and tunnelling

Security

• Proven experience applying least-privilege, need-to-know, and zero-trust principles against an as-is landscape
• Experience designing and automating data ingress controls for external party data, including PII detection, format/schema validation, and malware/virus scanning prior to landscape entry

Integration

• Strong experience working with complex legacy application and integration landscapes, ideally involving major system replacement or modernisation.
• Strong experience in integration or solution architecture, covering both legacy and modern integration approaches.
• Experience designing transition architectures, phased migrations and coexistence between legacy and new platforms.
• Ability to balance long-term strategic architecture with pragmatic delivery decisions.
• Expertise in change data capture and event streaming technologies (e.g., Apache Kafka, Kafka Connect, Debezium, Oracle GoldenGate)
• Experience with message queuing and pub/sub services (e.g., RabbitMQ, Amazon SNS, Amazon SQS)
• Experience with batch and file-based integrations, and common exchange formats such as JSON, CSV, XML, and Avro
• Working knowledge of API management and API-led integration patterns (e.g., API gateways, API-first design)

Operations & Cost Management

• FinOps experience, understanding key cost drivers and how to trade them off against other aspects of the solution
• DevOps experience, considering deployment, change management, test automation, release management, and load testing

Preferred / Nice-to-Have

• Demonstrable experience using large language models to accelerate discovery, documentation, solution design, and implementation
• Developed and supported data pipeline / data engineering solutions (e.g., ETL/ELT tooling such as AWS Glue, orchestration frameworks, data lake/warehouse integration patterns)
• Relevant cloud architecture certifications (AWS, Azure)
• Experience operating within regulated environments with data residency or compliance requirements
• Experience using AI tools to support system discovery, codebase analysis, documentation or solution design.

Experience Level

• 10 years of industry experience, covering hands-on experience configuring, governing, and operating system-level integrations across system landscape
• 2+ years of integration or solution architecture roles, including experience in multi-cloud and hybrid environments
• Demonstrable experience supporting major modernisation, migration or application replacement initiatives.
• Comfortable working across multiple programmes and understanding how individual solutions affect the wider enterprise landscape.
