Job description

Role: .NET Developer

Location: Neenah, WI (Onsite 5 days a week)

Duration: 4–5 month contract

About the Role

We're looking for a Senior .NET / WPF Developer to join an onsite team building and enhancing a laboratory information management and instrument integration system. You'll own the development of a complex desktop application spanning instrument communication, data processing workflows, and reporting — working directly with engineering, product, and QA stakeholders in an Agile environment. If you thrive in device-connected, data-intensive environments and enjoy solving real-world integration challenges, this role is worth a close look.

Key Responsibilities

Application Development (approx. 80%)

  • Design and develop a WPF-based desktop application using a modular, scalable architecture
  • Build and enhance workflows supporting lab data capture, calibration, measurement, review, and reporting
  • Implement multithreading and async programming patterns for real-time instrument interaction and responsive UI behavior
  • Develop data access, offline data handling, synchronization, and upload capabilities
  • Enable data export, reporting, and printing functionalities

Device & Instrument Integration (approx. 20%)

  • Implement device integration frameworks for multiple laboratory instruments and peripheral devices
  • Develop device management and configuration modules, including health checks, status monitoring, thresholds, and communication settings
  • Handle serial communication and device connectivity using COM protocols, device APIs, and SDKs

Collaboration & Quality

  • Partner with engineering, product, and QA teams on architecture, testing strategy, and deployment planning
  • Perform end-to-end validation, integration testing, and issue resolution across device and application workflows

Qualifications

Required

  • 5–8 years of software development experience
  • Strong proficiency in WPF and desktop UI development
  • Solid experience with C# and .NET Core / .NET Framework
  • Hands-on experience with serial communication and COM port-based integrations
  • Strong understanding of multithreading and async programming using Task and async/await
  • Experience integrating hardware devices through APIs, SDKs, or communication protocols
  • Knowledge of database access technologies such as ADO.NET or ORMs
  • Experience with modular application architecture and desktop application design
  • Strong problem-solving and debugging skills in device-connected environments

Preferred

  • Experience with laboratory systems, scientific instruments, or embedded device integrations
  • Familiarity with LIMS workflows, sample/result handling, or regulated lab environments
  • Knowledge of NI libraries or equivalent integration frameworks
  • Experience with installer creation and deployment packaging
  • Exposure to offline-first applications and sync mechanisms
