- Take ownership of work and follow through for on-time delivery.
- Optimize application performance and scalability.
- Troubleshoot, debug, and improve existing software applications, some of which are written using .NET, C#, and Python.
- Stay up-to-date with the latest Python, .NET and C# technologies and industry trends.
About You:
- Bachelor’s degree in Software Engineering or an equivalent qualification.
- Minimum of 4 years of full-time software development experience, including at least 1 year as a Senior Software Engineer.
- Proficiency in Python development, including high-volume ETL pipelines, data structures, design patterns, and test-driven development.

- Strong understanding of software development fundamentals, OOP, RDBMS, SQL, and Python best practices.
- Experience with databases (PostgreSQL, MS SQL) and cloud platforms. (AWS, GCP, Azure)
- Knowledge of version control (Git) and excellent problem-solving and debugging skills.
- Good professional communication skills in both written and spoken English, with the ability to work independently or as part of a team.
