Senior Software Engineer (.NET / C#)

BISTEC Global   Remote • Full-time

We are looking for a Senior .NET Developer to join a growing product team - someone who writes clean, solid code and is ready to take ownership beyond their own ticket. This role suits a developer who enjoys working close to the metal: optimizing queries, thinking about data access patterns, and keeping the codebase clean for the developers who come after them.

What you'll work on:

  • Building and maintaining .NET Core / ASP.NET Core APIs and services
  • Working across both legacy .NET Framework and modern .NET Core codebases - including migration work
  • Designing the data layer using Entity Framework Core and writing complex SQL queries
  • Collaborating with Angular frontend teams and contributing to code reviews

What we are looking for:

  • Strong hands-on experience with C# and .NET Core
  • Solid SQL skills - writing, reading, and reviewing queries with confidence (performance tuning)
  • Entity Framework Core - you understand how queries translate to SQL and how to avoid common pitfalls
  • Experience working with both .NET Framework and .NET Core applications
  • Good grasp of SOLID principles and the ability to apply them in real codebases
  • Experience with Angular is a plus

Why apply:

  • Work on a product used at scale with a team that takes code quality seriously
  • Real ownership - not just tickets, but outcomes
