• At least 5 years, ideally 10 years of experience developing web solution using Microsoft .NET Framework

• Advanced knowledge of C# programming

• Experience with API integrations and optimisation

• Knowledge of agile methodologies (scrum)

• Some knowledge of JavaScript and frontend development

• We value personal qualities and good communication skills

• Fluent/good oral and written English

• Work at least 3 days a week in the office in Krakow
