About this role

Join the best bank to work for in Bulgaria*.

Who we are:

Do you want to join a well-established bank with a start-up culture? No, we’re not joking!

We, at tbi, have been one the most profitable banks for years and we are growing at a fast pace. We’re a bank with a long history of success that operates as a start-up and we’re always on the lookout for new opportunities to grow our business. How do we do that?

It's all about our people. Our team is made up of brave, passionate and caring people who don’t just want to follow the same path – we want to transform into mobile-first, state-of-the-art lifestyle ecosystem. Our colleagues love working here – 70% of them would recommend tbi as an employer to their friends and family. Our people are engaged in challenging and meaningful work, inspired to grow their potential and career, encouraged to learn and empowered to take decisions.

That’s not corporate babble, it’s what our people say.

Do you want to play a key role in our unique success story?

If so, we're looking for a .NET Developer to join our team on the journey to success!

What You’ll do:

  • Design, develop, and maintain applications and modules across multiple in-house projects, working with both modern and established .NET technologies.
  • Develop new functionality using ASP.NET Core / .NET 10 with a Vue.js frontend.
  • Maintain and enhance existing applications built with ASP.NET MVC, .NET Framework, Razor, JavaScript, HTML and CSS.
  • Design and develop REST APIs and integrations with internal and external systems.
  • Take ownership of features from understanding the business need through to designing, developing, testing, and deploying the solution.
  • Investigate, troubleshoot, and resolve application and production issues, identifying the root cause rather than simply addressing symptoms.
  • Work with different database technologies, including SQL Server and Oracle.
  • Work with legacy applications, including ASP.NET Web Forms, when required.
  • Review and improve existing functionality, code quality, performance and maintainability.
  • Create and maintain appropriate technical documentation.
  • Collaborate with other developers through code reviews, knowledge sharing and support.
  • Move between projects and technologies as business priorities change, continuously learning and adapting to new challenges.
