Job description

ELEKS Software Engineering and Development Office is looking for a Senior Full-Stack (.NET + Angular) Developer in Poland or Ukraine.

ABOUT PROJECT

Our US-based client is the leading provider of Asset Liability Management (ALM) solutions for banks and credit unions.


REQUIREMENTS
  • Strong C# and .NET skills, with the judgment to work in an existing codebase – read it, understand the patterns, and improve it rather than paving over it
  • Solid experience with a modern SPA framework and TypeScript (Angular preferred; React/Vue transfers), plus comfort with HTML/CSS and a utility-first approach like Tailwind
  • Proven experience building and consuming RESTful web services in the cloud (Azure preferred)
  • Range across the stack – you have a home layer, but you’ll follow a problem from the UI through the API into a calculation or a query
  • Comfort reasoning about correctness: where a bug should have been caught, and how to verify numerical output (tolerances, expected values, regression of calculated results) rather than just HTTP 200s
  • Working knowledge of relational and/or document databases – schema design, writing queries, and knowing when the query is the bottleneck
  • Excellent communication in a distributed team – strong written English, and the ability to defend a design in review, ask hard questions in grooming, and explain tradeoffs to business stakeholders who aren’t engineers
  • 5+ years of relevant experience, and a bachelor’s degree in Computer Science, Mathematics, or a related discipline – or equivalent practical experience

    • RESPONSIBILITIES
  • Design and build features end-to-end – C# APIs and Azure Functions on the backend, Angular and TypeScript on the frontend – and own them from design through production
  • Work in the numbers, not just around them: extend and maintain the financial calculation engines at the heart of platform
  • Build out new UI, wired to the API – and help establish the patterns the frontend will scale on
  • Extend and debug our event-driven Azure architecture: Service Bus, queue workers, blob storage, App Configuration, and Key Vault
  • Model and query data in MongoDB, and push work to the right layer when a query or a calc-heavy path gets slow
  • Write tests as you build – unit, integration, and end-to-end – with a clear opinion on where each layer earns its keep, especially for calculated output
  • Treat performance and reliability as features: catch slowdowns the same week they’re introduced, not the quarter a client notices
  • Close the loop with production – monitor Azure alerts, logs, and traces (Application Insights), diagnose escaped defects across the stack, and feed what you learn back into the code and the tests
  • Use AI tools like Claude Code daily – to explore unfamiliar code, scaffold features, generate tests, and sharpen how the whole team ships
  • Raise the floor for the team: review PRs with substance, partner on testable design, and make good practice shared practice
  • Refine requirements with business analysts before they become code – and push back when a requirement doesn’t hold together
  • Serve as second-level support for internal user questions and issues
    •
