The future of aerospace and defense starts here. Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands. 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. In this role, you will design, develop, integrate, and maintain software applications that control electronic test equipment, execute automated test procedures, collect and analyze test data, and generate reports used for engineering development, qualification, and production acceptance. You will work closely with Electrical Design Engineers, FPGA Engineers, Flight Software Engineers, and Electrical Test Engineers to deliver scalable, reliable, and maintainable automated test solutions throughout the product lifecycle. 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. Required Qualifications: 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. Desirable Experience: 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. Colorado law requires us to tell you the base compensation range of this role, which is $110,000 - $135,000, determined by your education, experience, knowledge, skills, and abilities. What we can’t quantify for you are the exciting challenges, supportive team, and amazing culture we enjoy.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
