Job description

Описание

Software Mind develops solutions that make an impact for companies around the globe. Tech giants & unicorns, transformative projects, emerging technologies and limitless opportunities - these are a few words that describe an average day for us. Building cross-functional engineering teams that take ownership and crave more means we're always on the lookout for talented people who bring passion and creativity to every project.

Задачи

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 client’s internal team: stand-ups, documented design decisions, clean handoffs, CI/CD and repo conventions

Требования

3-5 years of commercial software development, including at least 3 years of production React and TypeScript (hooks, state management, Vite or Next.js) 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: ASP.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) – you'll 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)

Будет плюсом

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
