Job Description

Can you imagine contributing to simulation platforms that improve diagnostic laboratory workflows worldwide? 🧪💻

Join our expert team to work on a MedTech environment, contributing to the development of laboratory simulation solutions focused on diagnostic workflows and automated testing. You will apply your knowledge of NET Core, REST APIs, Docker and modern backend practices to build scalable and reliable applications. We are looking for engineers who actively collaborate, validate ideas critically and participate in technical discussions with ownership and curiosity.

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.

At ERNI, we highly value experience and technical knowledge. As a senior profile, you will have the space to continue growing, whether by deepening your technical skills or having greater influence on project decisions, with autonomy and the opportunity to share knowledge with other experts.
And if you are interested in mentoring, there is also space for that: supporting other ERNIans while still focusing on the technical excellence that sets us apart.

What you will bring 🤝
• Strong experience with .NET Core / C# backend development.
• Experience designing and maintaining REST APIs and working with Entity Framework.
• Hands-on experience with Docker containers and SQL databases such as PostgreSQL.
• Team player mindset with proactive communication and critical thinking when validating solutions or AI-generated suggestions.
• Experience with Git workflows and Agile collaboration.

You will be responsible for developing new functionalities for laboratory simulation platforms while maintaining and improving the current solution. Creating unit tests and technical documentation to ensure software quality and reliability. Collaborating with international teams in an Agile environment and contributing to the continuous evolution of simulation and testing tools used in diagnostic workflows.

What if the project ends?😅

We work on a wide variety of projects, technologies, and sectors, allowing you to keep growing in different environments. If a project ends or you feel ready for a new challenge, we will find another one that aligns with your professional development.

Our working model 👩‍🔬

We ask you to be available for key meetings. Need to leave for a doctor’s appointment or to pick up your child from school? No problem. We trust you to deliver quality work within your 40-hour workweek.

Our model is hybrid: we usually go to the office 2 days a week, though this depends on the project and team, but we love seeing each other’s faces; the best stories always happen in the office!

You will also enjoy:

🎓 We cover your certifications and reward technical achievements up to €1,400.
🏥 Private health and travel insurance.
💯 Full coverage for sick leave + 1 extra day off per month without medical leave.
🧘‍♀️ Free emotional, legal, and family support.
🏋️‍♀️ Gym discounts + sports compensation.
