Senior Full Stack .NET Developer (m/f/d)

Full-time (40 hours/week), hybrid

Your tasks at dacore

You will play a key role in developing custom software applications for technical and physical testing laboratories and help design new products based on modern cloud technologies—from architecture and implementation to quality assurance.

Specifically, that means:

  • Design software architectures and be responsible for technical decisions for projects
  • Design, develop, and optimize complex user interfaces in C# and WPF
  • Designing and maintaining database structures and high-performance queries in Microsoft SQL Server
  • Creating server applications in C# for data processing and notifications
  • Designing and implementing interfaces to third-party systems (ERP, measurement systems, etc.)
  • Architectural evolution of our platform towards clear layer separation and cloud-native operating models.
  • Conceptualization and prototypical implementation of AI-powered features in our specialized applications
  • Active use and evaluation of generative development tools to increase team quality and velocity
  • Anchoring Security by Design throughout the entire lifecycle
  • Knowledge sharing and technical support within the team
  • Create development and user documentation in German and English
  • Advise our customers on setup, operation, and technical issues
  • You have completed a degree in computer science or training as an IT specialist and have relevant professional experience in .NET development.
  • You surely design complex data structures, routinely apply common design patterns, and make well-founded architectural decisions.
  • You have experience with WPF and the MVVM pattern, and you value performant, maintainable user interfaces.
  • Ideally, you'll bring cloud experience – Azure preferred, alternatively AWS or GCP.
  • You've already integrated AI functionality into productive software – or you're eager to do so.
  • You use generative development tools in your daily life as a matter of course and can judge when they help and when they don't.
  • You bring a solid understanding of security: secure coding, authentication, and authorization concepts.
  • You enjoy taking responsibility, sharing your knowledge, and actively participating in technical discussions.
  • You communicate fluently in German and have good English skills.
  • You enjoy evaluating new technologies and integrating them into existing systems.

You work in cross-functional, agile teams alongside colleagues from web development, mobile development, project management, and directly with our customers. Full Stack at dacore means: you shape the entire software lifecycle — from planning and architecture through development and testing to deployment, training, and operations. Our customers are technical-physical testing laboratories involved in the product development process. Their requirements are as individual as the products they test. That's exactly what makes the work varied: this isn't about standard software with repetitive workflows, but about tailor-made solutions in a technically exciting environment.

What our team members say about us

Carmen Kupsch
Lead Developer, with dacore since 2016

„Over the years, I have come to appreciate the flexibility in particular. Whether it's doctor's appointments, private appointments or sports that you want to do in daylight in winter, everything can be arranged individually.“

Joachim Meyer
Head of Project Management, with dacore since 1996

„Already 25 years at dacore, haven't regretted (almost) a day and it's still fun. Super solid company, I'm retiring here!“

Stephan Fruth
Full Stack Developer, with dacore since 2006

„The flexible working hours make it easy to balance work and family life. I also think it's great that neither vacation nor hours on the time account expire. This also makes it possible to take longer breaks, e.g. to build a house or take a sabbatical.“

Tobias Weber
Full Stack Developer, with dacore since 2019

“From the very first day of my apprenticeship, everyone offered to be on a first-name basis. Since then, I’ve always been treated as a colleague on equal footing — no matter who I’m talking to.”

Frank Neusinger
Project Manager, with dacore since 2018

„I can work completely remotely and when I come into the office, I have my own workstation there too.“
