Role Overview

We are seeking a Senior Solution Architect to join one of our Government Clients across a technology platform design project.

You will own and define the target state architecture, driving technology modernisation across an estate that combines legacy .NET services, modern cloud-native components, identity and security platforms, and AWS managed data services.

  • Data Architecture: Oversee logical/physical data across PostgreSQL, MySQL, Oracle, and Elasticsearch/OpenSearch with a focus on data minimisation and security
Key Requirements
  • 10+ years in software engineering/architecture, with 3+ years as a Solution/Technical Architect on complex platforms.
  • Active SC Clearance
  • Proven experience in technology modernisation and legacy-to-cloud migration paths.
  • Core tech stack: .NET / .NET Core, Python, JavaScript/TypeScript (Vue.js, React).
  • AWS Managed Services (RDS, SQS, DynamoDB, OpenSearch, ECR) and AWS Well-Architected Framework.
  • Terraform (IaC) and Docker at scale.
  • Identity, authentication, and API Gateway platforms (e.g. WSO2, RADIUS).
  • Background in regulated, security-conscious, or public sector environments.
Desirable
  • TOGAF or AWS Certified Solutions Architect (Professional).
  • AWS SageMaker or ML/analytics tooling.
