Job Description
Project – the aim you’ll have
Join a next-generation risk analysis and scoring platform built for a payments technology company. The platform combines the client’s own risk rules with AI-driven, pre-scored risk feeds from a global card network over high-volume payment data under PCI DSS. You’ll own the C#/.NET services and API contracts the analyst-facing apps run on, in a small AI-first delivery team alongside a frontend-leaning developer.
Role – how you’ll contribute
• Design, build and ship production C#/.NET services and REST APIs serving high-volume payment and risk data under PCI DSS constraints
• Own API contracts with the front end: typed OpenAPI contracts, versioning and backward-compatible change
• Write efficient data access against the operational database and Microsoft Fabric Gold-layer risk tables at analyst-scale volumes
• Implement security-critical concerns: authentication, authorization, audit logging and PCI-safe handling of tokenized card data
• Contribute to the React and TypeScript front end – building features end to end, reviewing and pairing
• Use Claude Code or an equivalent agentic coding tool as your primary accelerator, backed by unit, integration and contract tests, while owning the quality of every line merged
• Maintain Dockerfiles and Compose configurations, support deployments to AKS and contribute to Azure DevOps CI/CD
• Implement against the target architecture set by the client’s architecture group, raise risks early and hand off work the internal team can own
