[WAP] Full-Stack Developer (React, .Net)

Project the aim youll have

Join a next-generation risk analysis and scoring platform built for a payments technology company. The platform combines the clients own risk rules with AI-driven pre-scored risk feeds from a global card network. Youll build the analyst-facing interfaces where risk teams review transactions and merchants and work their alert queues in a small AI-first delivery team alongside a backend-leaning senior developer.

Role how youll contribute

• Build and ship production React and TypeScript features for risk analyst interfaces: transaction and merchant risk views score explanations alert queues data-heavy tables filters and charts
• Extend the C#/.NET endpoints behind your features (new fields filters endpoints) within API contracts owned by the senior developer
• Integrate the front end with platform APIs handling loading error pagination and caching states cleanly
• Keep large-dataset UIs fast through virtualized tables smart data fetching memoization and regular profiling
• Use Claude Code or an equivalent agentic coding tool as your primary accelerator while owning the quality of every line merged
• Write unit component integration and end-to-end tests and review and harden AI-generated code before it reaches production
• Respect the PCI boundary across the stack: masked and tokenized card data only secure session and token handling
• Work closely with the clients internal team: stand-ups documented design decisions clean handoffs CI/CD and repo conventions

Qualifications :

Expectations the experience you need

• 35 years of commercial software development including at least 3 years of production React and TypeScript (hooks state management Vite or )
• Experience building data-heavy UIs: tables grids and charts over large datasets (e.g. TanStack Table AG Grid Recharts ECharts)
• Working proficiency in C#/.NET: Core Web API EF Core or Dapper and enough SQL to change endpoints safely
• REST API integration with typed clients and server-state libraries such as TanStack Query
• Daily hands-on use of agentic AI coding tools (Claude Code Cursor Copilot Workspace Codex or similar) youll demo your workflow live
• Testing discipline: Jest or Vitest React Testing Library Playwright or Cypress xUnit or NUnit
• Solid frontend fundamentals: modern CSS accessibility (WCAG) browser performance and web security (XSS CSP token handling)
• Docker and Docker Compose Git CI/CD (Azure DevOps GitHub Actions or similar)

Additional skills the edge you have

• Payments card processing risk/fraud or financial services experience ideally with PCI-scoped applications
• Design systems and component libraries (MUI Fluent UI) and Storybook
• Advanced data visualization (D3 time-series and distribution charts) or UIs for LLM-backed features
• Identity in SPAs: OAuth2/OIDC MSAL / Microsoft Entra ID
• Prior consulting or staff-augmentation experience embedded in a client team
