Senior Technical Architect - Integration

Senior Technical Architect | Integration & Event-Driven | Up to £700/day inside IR35 | Remote

THE ROLE

A central government programme needs a Senior Technical Architect. The integration specialism is what decides it, not the general architecture list underneath.

THE INTEGRATION SPECIALISM — this is the seat

• Event-based architecture design and patterns, including pub-sub and data streaming
• Modelling techniques, tools and standards for event architecture
• Across multiple domains in private data centres and public clouds, not one or the other
• Microservice and API-led architecture
• Integration design tools, techniques and best practice

THE TECHNICAL GROUND

• AWS as the platform. This account is AWS heavy throughout
• EventBridge, SNS and SQS, MSK or Kinesis, Kafka, Confluent, Kafka Connect, RabbitMQ or ActiveMQ
• Schema registry, ordering guarantees, idempotency, replay and dead letter handling
• API Gateway, contract-first design, versioning, REST and asynchronous patterns
• Lambda, Step Functions, ECS or EKS
• Transit Gateway or Direct Connect, and hybrid connectivity across both sides of an estate

THE STANDARD LIST

• Architecture design across on-prem, cloud and hybrid covering networking, security, presentation, middleware, database and integration
• Principles, patterns, technical radars, practices and standards
• Working with delivery teams across agile, waterfall and hybrid, concept to go-live
• Translating business requirements into technical solutions with traceability you can demonstrate
• Architecture modelling techniques and tools

WHAT THEY ARE LOOKING FOR

• UK central government delivery, and ideally longer tenures rather than a run of short stints
• SC eligible
• Held Senior Technical Architect or equivalent at SFIA 5
• Evidence of the hybrid estate, not just one cloud

WHY THIS ONE

The last person in this seat won it on one line of their CV: a hundred and three applications out of seven European data centres into public cloud on a single programme. If you have only ever worked one side of that divide, this will be a hard sift. If you have worked both, there are not many of you and this is worth a conversation.
