Senior Developer, Full-Stack (C#, React) – Potential for promotion to IT Lead (m/f/d)

Employer

  • We are digital architects for regulatory masterpieces, transforming complex legal requirements into smart, digital workflows
  • For over three decades, we have set the gold standard. We dominate the market for SMEs and corporations
  • Stable team of 50 employees, striking the perfect balance between professionalism and a personal work environment

Senior Developer / Tech Lead, Full-Stack (C#, REACT) (m/f/d)

Responsibilities

  • As a coach and mentor, you are the guiding star of our MantineManiacs. You don’t just love SOLID—you live and breathe clean code—whether through inspiring code reviews or fine-tuning our toolchain components like SonarQube and Grafana. Your goal: A stable codebase, so secure and high-performing that everyone can sleep soundly at night
  • Bureaucratic jungle? Not with you. You translate dusty laws into fluid IT processes and make our customers compliant—and happy
  • You independently implement software solutions—idea → concept → development → testing → maintenance—and bring your own style to the table
  • You create technical requirement analyses for migrating legacy software—perhaps soon with the help of AI—to a modern DDD architecture, all while keeping the big picture in mind
  • You continuously grow and develop alongside the team

Profile

  • Several years of experience in backend development with C# / .NET
  • Strong knowledge of modern frontend technologies, e.g., React / TypeScript
  • Experience with WebAPI, MS SQL Server, and relational databases
  • Ideally, experience in migrating legacy systems (e.g., VB.NET)
  • Ability to analyze requirements and independently develop and implement solutions
  • .NET Framework / .NET Core in the programming languages C# and VB.NET
  • ASP.NET Core
  • MS SQL Server
  • DevOps experience, e.g., in Docker, Linux administration: Ubuntu, GitLab CI/CD

Benefits

  • 100% remote work possible – work where you are most productive
  • Flexible hours and Short Fridays for a relaxed start to the weekend
  • Modern work environment and a dedicated, supportive team
  • Opportunities for specialization and professional development
  • Many other perks
