What you'll be doing

Reporting to The Head of Architecture we are looking for a highly skilled Contract Senior C# .NET Engineer to join our team and take ownership of delivering a new OpenSearch-based service in AWS. This role is hands-on, end-to-end, and central to solving critical performance bottlenecks in our mature software platform. You'll design, build, and ship a reusable, modular service that eliminates costly DB lookups and delivers scalable, cloud-native search functionality.

Lead the design and implementation of a new OpenSearch-based service to handle large-scale search queries. Build the service in C# .NET, ensuring it is modular, reusable, and extensible. Migrate expensive, multi-table database searches to a performant OpenSearch solution. Architect and deploy infrastructure using Infrastructure as Code (Terraform, AWS CDK, or similar). Leverage AWS cloud-native technologies to ensure scalability, reliability, and maintainability. Work closely with product and engineering stakeholders to refine requirements and priorities. Ensure robust integration between the new search service and the existing core platform. Establish monitoring, logging, and alerting for the new service. Document the architecture, decisions, and processes to enable handover and long-term maintainability.
