Job Description

 

Project – the aim you’ll have

Lead delivery of a next-generation risk analysis and scoring platform for a payments technology company. It combines the client’s risk rules with AI-driven, pre-scored risk feeds from a global card network over a Microsoft Fabric data estate. You’ll lead an AI-first team of C#/.NET and React developers, a Python developer and a data platform engineer – a hands-on role with about 70% coding.

Role – how you’ll contribute

  • Design, build and ship production C#/.NET services, APIs and React features, taking on the hardest slices when the team is blocked
  • Contribute to and review the team’s Python work, holding it to the same standard as the .NET codebase
  • Use Claude Code or an equivalent agentic coding tool as your primary accelerator, backed by automated tests, and harden AI-generated code before it reaches production
  • Deploy via Docker, Helm and Azure DevOps pipelines to AKS, and integrate services with the Microsoft Fabric data estate
  • Translate the architecture group’s designs into technical plans, task breakdowns and code-level designs
  • Run code reviews and set engineering standards for testing, review practices and AI tooling (CLAUDE.md files, custom commands, guardrails)
  • Track technical status, surface risks early, and unblock and mentor developers through reviews and pairing
  • Act as the team’s technical point of contact with the client: lead stand-ups, join design reviews, report status and ensure clean handoffs

Qualifications

Expectations – the experience you need

  • 12+ years of commercial software development, including 5+ years as a technical lead on production systems
  • Expert C#/.NET (ASP.NET Core, REST API design, async, EF Core or Dapper) with active hands-on .NET coding in the last 12 months
  • Working proficiency in Python (typing, async, FastAPI, pytest) and in React and TypeScript, enough to build features and review code
  • Relational database and distributed-systems skills: schema design, query tuning, transactional correctness, idempotency, failure handling
  • Docker, Kubernetes (AKS preferred), Helm, CI/CD (Azure DevOps or similar) and working knowledge of Terraform
  • Daily use of agentic AI coding tools (Claude Code, Cursor, Copilot Workspace, Codex or similar) and experience setting AI-tooling standards for a team – you’ll demo your workflow live
  • Proven ability to lead distributed teams through design and code reviews without direct authority, with clear written communication
  • Ability to operate autonomously with minimal ramp-up in an existing codebase

Additional skills – the edge you have

  • Payments, card processing, risk/fraud or merchant services experience, ideally with PCI DSS-scoped systems
  • Microsoft Fabric, Delta Lake or building services over analytical data stores
  • Shipped LLM-backed or agentic features: RAG, LangGraph or similar, and evaluation practices
  • Messaging, observability and identity: Service Bus, Event Hubs or Kafka; OpenTelemetry, Azure Monitor; OAuth2/OIDC, Entra ID
  • Prior consulting or staff-augmentation experience leading a team embedded in a client organization

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
