NET Team Lead

Do you want to work for an International Service Delivery Center in Valencia as a .NET Team Lead?

You will lead the development and delivery of high-quality .NET software solutions in regulated domains such as MedTech for national and international clients. These business- and safety-critical projects demand strong engineering discipline, regulatory awareness, high quality standards and close collaboration with stakeholders.

You will work in international, multidisciplinary teams, within an environment that values technical excellence, ownership, and collaboration.

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

• Minimum 5+ years of professional .NET development experience and proven experience in a team lead role
• Strong expertise with C# and modern .NET ( .NET Core / .NET 6+ )
• Experience building backend services and APIs using ASP.NET / ASP.NET Core and RESTful APIs
• Solid practical application of Clean Code and Clean Architecture principles
• Experience with relational databases (SQL Server or similar) and ORMs (Entity Framework / EF Core)
• Cloud and DevOps experience designing and implementing CI/CD pipelines and DevOps practices
• Experience working in Agile environments (Scrum/Kanban)
• Frontend or cross‑platform familiarity (Flutter, Angular, React, Blazor) is a plus
• English level C1 or higher
• Experience with MedTech or other high regulated environments

You will be responsible for

• Design, develop, test, and maintain .NET-based applications and services.
• Guide other engineers through coaching, code reviews and pair‑programming to improve skills, autonomy and code quality.
• Support technical decisions.
• Ensure alignment between technical solutions and business or regulatory needs.
• Take ownership of features or components throughout their full lifecycle.
• Collaborate closely with international team members, product owners, architects, and stakeholders.

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'll find another one that aligns with your professional development.
