Overview

We are hiring a Software Engineer to support the development of test equipment and engineering systems used in advanced defense and missile technologies.

This role is part of a hands-on engineering team responsible for building software that supports system validation, integration, and production environments. The work directly impacts real-world systems, where reliability, performance, and precision are critical.

You will develop software that interfaces with hardware, instrumentation, and system-level test platforms used to validate complex defense systems across engineering labs, manufacturing, and deployment environments.

What You Will Do

• Design and develop Windows-based applications using C# and C++
• Build software for test equipment, automation systems, and engineering tools
• Develop instrument drivers and hardware interface software
• Integrate software with lab equipment, test stations, and production systems
• Troubleshoot issues across software, hardware, and instrumentation environments
• Support system-level testing, validation, and production readiness activities
• Collaborate with systems, hardware, and manufacturing engineering teams
• Contribute to requirements development, design reviews, and system architecture
• Manage multiple software efforts in a fast-paced engineering environment
• Mentor junior engineers and support team development

Program Environment

This role supports a long-term defense program focused on advanced system validation and production support for mission-critical technologies.

Work includes:

• Software used to test and validate complex defense systems prior to deployment
• Integration with hardware systems and sensor-driven platforms
• Support for engineering labs, system demonstrations, and production environments
• Involvement in full lifecycle activities from development through sustainment

This is a highly technical environment where software directly interacts with real systems and contributes to operational readiness.

Required Qualifications

• Bachelor’s degree in STEM field
• 5+ years of software engineering experience (or 3+ with advanced degree)
• Active DoD Secret Clearance (required to start)
• Experience with C# and/or C++ development
• Experience developing Windows-based applications (Visual Studio)
• Experience building software that interacts with hardware, instrumentation, or test systems
• Strong understanding of object-oriented design and system-level application development
• Ability to troubleshoot across software and hardware environments
• Experience working in cross-functional engineering teams

Preferred Qualifications

• Experience with automated test equipment (ATE) or test systems
• Experience developing instrument drivers or hardware interface software
• Familiarity with communication protocols such as TCP/IP, UDP, or RS-422
• Experience with Azure DevOps, GitHub, or similar version control tools
• Experience with UML or system architecture modeling
• Experience working in Agile or Waterfall development environments
• Exposure to hardware/software integration in lab or production settings
• Experience mentoring or leading engineers

How Success Is Measured

• Software integrates successfully with test equipment and hardware systems
• Applications support engineering, validation, and production environments
• Issues across software and instrumentation layers are resolved effectively
• Deliverables support system-level testing and production timelines
• Code is reliable, maintainable, and supports long-term system sustainment

Work Environment

• Onsite, hands-on engineering environment
• Combination of lab, production, and software development work
• Close collaboration with systems, hardware, and manufacturing teams
• Exposure to real-world system validation and deployment

Why This Role

• Work on systems that directly support real-world applications
• Build software that interacts with hardware and test environments
• Join a team focused on solving complex engineering challenges
• Strong opportunity for long-term conversion and career growth
