At Boeing, we innovate and collaborate to make the world a better place. We’re committed to fostering an environment for every teammate that’s welcoming, respectful and inclusive, with great opportunity for professional growth. Find your future with us.

Boeing Test and Evaluation (BT&E) is currently seeking an Associate Flight Test Data Processing Software Engineer to join the Midwest Data Processing & Visualization team in Berkeley, MO.

Boeing Test & Evaluation’s Midwest Data Processing & Visualization team develops software applications and tools for instrumentation system setup and configuration; real-time monitoring; and post-test data processing, storage, access, visualization, and analysis. These tools enable flight test operations teams to efficiently collect, view, and analyze high-quality time history data to validate specially equipped aircraft and weapon systems.

This requires a wide range of skills, including experience with modern software development practices, user interface design, database design and interaction, management of large volumes of data, operations in real-time environments, and hardware and software integration. C/C++, C#, WinForms/WPF/WinUI or Blazor, SQL Server, Visual Studio, .NET framework, git, and Azure DevOps are used daily to maintain legacy software and develop new applications as needed to support our users.

We’re looking for self-starters who can handle a variety of tasks; design, develop, and troubleshoot Windows-based software applications; derive requirements and determine the best path forward even when working from an incomplete work scope; and work efficiently in a dynamic team environment.

Develop or modify legacy (C++) or modern (C#) applications based on defined requirements
Develop unit or system tests to verify operational and functional requirements
Troubleshoot and resolve software integration issues and production anomalies

1+ years of experience in developing software
1+ years of experience with system integration, testing, and troubleshooting
1+ years of software development experience in C++ and C# using Microsoft Visual Studio and .NET

Preferred Qualifications (Desired Skills/Experience):

An active U.S. Security Clearance in the past 24 months
Experience with Agile software development methodologies
Experience with data communication protocols, including Ethernet, MIL-STD-1553, ARINC, CAN bus, and/or Serial
Experience collaborating with users to develop software requirements, and perform integration or testing/verification activities
Bachelor’s degree or higher in computer science, computer engineering, or similar

The Boeing Company also provides eligible employees with an opportunity to enroll in a variety of benefit programs, generally including health insurance, flexible spending accounts, health savings accounts, retirement savings plans, life and disability insurance programs, and a number of programs that provide for both paid and unpaid time away from work.
