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
Expectations – the experience you need
- 7+ years of commercial software development, including 5+ years of production-grade C#/.NET (ASP.NET Core, async, DI, EF Core or Dapper)
- Strong API design: REST conventions, OpenAPI contracts, versioning and evolving APIs without breaking consumers
- Relational database and distributed-systems skills: schema design, query tuning, transactional correctness, idempotency, failure handling
- Working proficiency in React and TypeScript – able to build features end to end and review frontend code
- Daily, hands-on use of agentic AI coding tools (Claude Code, Cursor, Copilot Workspace, Codex or similar) and a track record of shipping AI-accelerated code that holds up in production – you’ll demo your workflow live
- Containers: Docker (multi-stage builds, hardening), Docker Compose and Kubernetes (AKS preferred)
- Testing discipline: xUnit or NUnit, integration testing with real dependencies (e.g. Testcontainers) and contract testing
- Git, CI/CD (Azure DevOps, GitHub Actions or similar) and autonomy in an existing codebase
Additional skills – the edge you have
- Payments, card processing, risk/fraud or merchant services experience, ideally with PCI-scoped systems
- Microsoft Fabric, Delta Lake or building APIs over analytical data stores
- Messaging and observability: Azure Service Bus, Event Hubs or Kafka; OpenTelemetry and Application Insights
- Identity standards: OAuth2/OIDC, Microsoft Entra ID, managed identity
- Python and exposure to LLM-integrated or agentic applications (e.g. LangGraph); prior consulting experience
What we offer:
- Flexible and remote cooperation options
- International projects with leading global clients
- Travels related to international projects
- Non-corporate atmosphere
- Access* to language classes
- Access* to knowledge-sharing initiatives
- Access* to private healthcare and life insurance
