With a vast network of laboratories and a mission-driven culture, it offers engineers the opportunity to work on impactful systems that directly support life sciences and environmental safety.

About This Role

As a Senior Software Engineer, you will architect and enhance LIMS applications using the Microsoft stack, ensuring seamless lab operations for BioPharma Product Testing. Your contributions will optimize data workflows, improve compliance, and accelerate drug development, making a tangible difference in public health.

💡 A Day in the Life

Your mornings start with a stand-up via Teams with developers in Europe and the US, discussing sprint progress. You then dive into coding a new Angular module for sample chain-of-custody, followed by a code review of a colleague's .NET Core API. After lunch, you troubleshoot a production issue in Azure, optimizing a slow query, and end the day documenting architectural decisions for the next sprint.

⚠️ Common Mistakes to Avoid

  • Submitting a generic resume without tailoring keywords like 'Entity Framework Core', 'Angular 15', or 'LIMS'.
  • Overlooking the importance of testing—failing to mention unit testing (e.g., xUnit, Jasmine) or integration tests.
  • Ignoring the global team aspect—not preparing examples of cross-time-zone collaboration or Agile ceremonies.
