Can you imagine modernizing a business-critical platform used in automotive workshops while shaping its transition to a modern web architecture?
Join our expert team to work on an Automotive sector modernization initiative, contributing to the evolution of a workshop management solution. You will apply your knowledge of .NET, API Development, AWS and modern software engineering practices to transform a legacy desktop application into a scalable web-oriented platform. You will collaborate with multidisciplinary teams while ensuring system stability and enabling continuous modernization.
At ERNI, you are never just a number. Even if you work on an external project, you will feel part of the team and always supported.
How do we make this happen?
With people. Besides your team and manager, you will have several support figures like a godparent, who will help you with the practical and administrative aspects of daily life during your first 6 months. And the second most important person after you, your mentor, who will guide you through your entire onboarding and career at ERNI.



You will have regular 1:1 meetings with them, and recurrently, you will work on your development plan to define your short-, medium-, and long-term goals.

Knowledge of AWS cloud services and CI/CD practices.
