  • Participate in code reviews, unit testing, and software deployment activities.
  • Assist in monitoring, debugging, and improving application performance, security, and reliability.
  • Assist in troubleshooting application issues and contribute to root cause analysis under the guidance of senior engineers.
  • Collaborate with cross-functional teams including engineering, product, IT security, and release management.
  • Assist in the development and integration of AI-powered features and intelligent user experiences using modern AI technologies and services.
  • Stay updated on emerging trends in .NET, front-end technologies, cloud computing, and AI.

You've got what it takes if you have...

  • Basic programming knowledge in Java, Python, C#, or another object-oriented programming language.
  • Good understanding of relational databases and SQL, including database design fundamentals, query writing, stored procedures, and data modeling.
  • Strong understanding of object-oriented programming (OOP) principles; familiarity with design principles such as SOLID and KISS is a plus.

  • Understanding of software development concepts and application architecture principles.
  • Familiarity with version control systems such as Git and Bitbucket is a plus.
  • Familiarity with NoSQL databases is a plus.
  • Awareness of application performance concepts and optimization techniques.
