What is a Contract Developer job?

A Contract Developer is a software developer hired on a temporary or project basis to create, modify, or maintain applications and systems. They typically work for clients or companies under a contract agreement rather than as a full-time employee. Their responsibilities may include coding, debugging, testing, and collaborating with teams to meet project requirements. Contract Developers often specialize in specific programming languages or technologies and may work remotely or on-site. The duration and terms of their work vary based on the contract and project scope.

What are some common challenges faced by Contract Developers and how can they be managed?

Contract Developers often work on multiple projects or with various clients, which can present challenges such as rapidly adapting to different codebases, meeting tight deadlines, and managing shifting priorities. Effective communication with stakeholders and clear agreement on project scope and deliverables can help minimize misunderstandings. Staying organized through productivity tools and maintaining continuous skills development also contribute to handling workload fluctuations. By proactively addressing these challenges, contract developers can deliver high-quality work and build strong professional relationships.

What are the key skills and qualifications needed to thrive in the Contract Developer position, and why are they important?

To excel as a Contract Developer, strong programming skills, experience with relevant frameworks, and a solid educational background in computer science or related fields are essential. Familiarity with version control systems like Git, project management tools, and possibly certifications such as AWS Certified Developer or Microsoft Certified: Azure Developer Associate are advantageous. Excellent time management, client communication, and adaptability are critical soft skills for success in contract-based work. These skills enable a Contract Developer to efficiently deliver quality results, meet client expectations, and thrive in dynamic, project-oriented environments.

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
