Senior Test Software Engineer

About the role

Modern aerospace and defense systems require sophisticated automated test capabilities to verify the performance, reliability, and quality of mission-critical avionics throughout development, qualification, and production. As a Senior Test Software Engineer, you will develop the software that powers our automated test systems, enabling efficient verification and validation of FPGA-based electronics, embedded systems, and avionics hardware supporting advanced missile and defense programs.

The ideal candidate enjoys solving complex hardware/software integration challenges, developing robust automation frameworks, and building test systems that improve product quality while reducing development and production cycle time.

Responsibilities

• Design, develop, and maintain software for automated test equipment (ATE), Hardware-in-the-Loop (HIL) systems, engineering development laboratories, and production test stations.
• Develop software to control laboratory instrumentation including oscilloscopes, digital multimeters, signal generators, power supplies, electronic loads, switching systems, and other electronic test equipment.
• Translate engineering test requirements and procedures into automated software solutions that produce repeatable, traceable, and reliable test results.
• Design reusable software architectures, libraries, and frameworks that support multiple products and test platforms.
• Develop operator interfaces, automated test sequencing, data acquisition, measurement analysis, logging, and report generation capabilities.
• Integrate software with avionics hardware, FPGA designs, embedded software, and external instrumentation to support hardware verification and system integration.
• Support hardware integration, qualification testing, environmental testing, and production acceptance activities.
• Troubleshoot software, instrumentation, and hardware integration issues, perform root cause analysis, and implement corrective actions.
• Develop software documentation including requirements, design descriptions, user documentation, and test procedures.
• Support software configuration management, version control, and continuous improvement initiatives.
• Collaborate with cross-functional engineering teams to improve test efficiency, automation coverage, and overall product quality.

Requirements

• Bachelor's degree in Computer Engineering, Computer Science, Electrical Engineering, Software Engineering, or related technical discipline.
• 5+ years of experience developing software for automated test systems, laboratory automation, or hardware integration.
• Proficiency in one or more programming languages such as C#, Python, C++, LabVIEW, or similar.
• Experience developing software that interfaces with electronic test instrumentation using communication standards such as VISA, GPIB, USB, Ethernet/LXI, Serial, or PXI.
• Experience developing automated test sequences, data acquisition, measurement processing, and test reporting.
• Familiarity with software architecture, object-oriented programming, and software design best practices.
• Experience troubleshooting hardware/software integration issues in laboratory or manufacturing environments.
• Experience using version control systems such as Git or Azure DevOps.
• Strong analytical, debugging, and problem-solving skills.
• Must be a U.S. Person with the ability to perform work subject to ITAR/EAR regulations and applicable program requirements.

Skills

• Experience developing automated test software for aerospace, defense, or other high-reliability electronic systems.
• Experience supporting FPGA-based systems, embedded software, or mixed-signal electronic hardware.
• Experience developing software for Hardware-in-the-Loop (HIL) or Automated Test Equipment (ATE) systems.
• Experience controlling electronic instrumentation using NI VISA, SCPI, PXI, or similar communication frameworks.
• Experience with test management tools such as NI TestStand or equivalent automated test executives.
• Experience with multithreaded software development and asynchronous hardware communication.
• Familiarity with digital communication protocols such as SPI, I²C, UART, CAN, Ethernet, or RS-422/485.
• Experience with qualification testing, environmental testing, and production acceptance testing.
• Experience developing software under configuration management and requirements-driven development processes.
• Familiarity with scripting and data analysis tools such as Python, MATLAB, or SQL.
• Active U.S. Department of Defense Security Clearance or the ability to obtain one.
